Hajime Nagumo/Relationships

Yue
The vampire princess, Aletia became Hajime's most important person after he fell into the Abyss. At first, when Hajime discovered that she was sealed in the abyss of the Great Orcus Labyrinth, he was willing to leave her behind out of the cautious belief that she was sealed there because she was dangerous. However, after she begged him to help her by saying she was betrayed just like him, he freed her and renamed her "Yue" at her own request. As the two fought together to conquer the Great Labyrinth in order to escape, they quickly grew close due to their similar backgrounds and circumstances. Even in public, they tend to go into their own "pink world" and ignore everything in their surroundings. Whenever there is danger, Hajime and Yue always prioritize each other's safety. The two have a deep understanding of each other as they are able to discern each other's thoughts.

In the Haltina Labyrinth, Hajime was instantly able to tell that Yue had been replaced by a slime that was impersonating her and was later instantly able to identify Yue even though she was forcibly transformed into a goblin. Although she became a goblin, Hajime was able to understand her. Even though Hajime is surrounded by women who want to be his lovers and Yue herself wants him to be intimate with her, he has never wavered in loving her. His reasoning being that because he is a man who would never cheat on the woman he loves and wants to be monopolized by Yue since, if the situation was reversed, he would never want Yue to be with anyone but him as for Yue wants the same thing. Later in volume 8 he accepts the love of Shea after being convinced by Yue.

If anyone saying Yue's name without honorifics, Hajime make them suffer in a worse case as they have no rights to say Yue's name because he is the one who gave Yue her name when he brutalized Kouki.

When Yue was captured by Eri and temporarily possessed by Ehit, Hajime was engulfed with tremendous rage as he killed his way to reach to Yue.

In battle, they move with perfect synchronicity and are able to anticipate each others moves. After clearing the Labyrinths and after Ehit's death, Hajime holds hands with Yue to use ancient magic and creates a crystal key which enables him to open a doorway back to Japan. It is Hajime's wish to bring Yue and the other girls back to his world.

Kaori Shirasaki
Hajime has always seen Kaori as a friend, although her attention only brought him nothing but trouble. When Hajime began his journey he decided that he wants nothing to do with his former classmates after his transformation, but the moment he heard from Kousuke Endou that Kaori was in trouble, he went in the Great Orcus Labyrinth to save her to pay off her kindness. While Hajime said that he would not respond to her feelings because he was in love with Yue, she refused to give up winning him over. After that she decided to travel with Hajime to earning his affection despite his completely different personality. On the harsh journey, Hajime has offered Kaori to return her to Shizuku when she was saddened by her weakness compared to other members of Hajime, but she refused the offer and always wanted to stay by his side. As shown, Kaori is important to Hajime when he saved her from the influence of an evil spirit. Due to her unbreakable love for Hajime, Kaori always believed everything when Hajime told her that she easily accepted of Ehit's true nature as an evil god who used her and Hajime as pawns in "The Chessboard of Life".

Later after Kaori was killed by Hiyama, he became enraged and unleashed his true power by destroying each of the forces of Eri undead soldiers and slaughtering Hiyama, while at the same time he was determined to revive her using spirit magic as he promised her to put her soul in a stronger body at Kaori's request because she did not want to remain weak any more. Kaori is the only one of his wives that shares Hajime's otaku hobbies.

Shea Haulia
During their first meeting, Hajime's impression of Shea was negative due to her excessively clingy attitude that he wouldn't hesitate to strike her for out of annoyance. Hajime wouldn't allow Shea to travel with him until she became strong so she trained with Yue so that one day she could stand next to them in battle.

As time passed Hajime and Yue began to see Shea as part of their family, but to Shea's and, shockingly Yue's great disappointment, Hajime could not see Shea in a romantic light. However, that began to change during their return to the Haltina forest, where her concern for her father(who had gone missing) damped her smile so much that Hajime decided to alter his plans to save Cam and the others first before he goes to the Haltina labyrinth. After the Haltina labyrinth, Hajime eventually realized that Shea is just as important and irreplaceable to him as Yue and has begun to show his previously hidden feelings for her and subsequently confessed to her. Without realizing it the two have created their own "pink world" while they are alone. While Hajime has come to respect Shea for how far she's come, he does miss the old useless Shea, feeling nostalgic when he does.

Tio Klarus
At first Hajime and Tio met as unwilling enemies in battle due to her being manipulated by Yukitoshi Shimizu's dark magic while on a quest from the adventurer's guild. Even when she was snapped out of the mind control after being defeated by Hajime and explaining the circumstances behind her attack, Hajime was still willing to kill her out of the annoyance of her attack on him which Shea compared to her own first meeting with him. His attempt on her life while ignoring her circumstances and pleas shocked and terrified her before Yue convinced him to spare her. After this first encounter which involved arguably "tainting" her, Hajime has been followed by the masochistic and incredibly perverted dragonman who refers to him as her "master". Hajime constantly finds himself punishing her for her various misdeeds during their travels which makes Tio incredibly happy much to his dismay and disgusts everyone else.

In Volume 4, Hajime trusted Tio enough to guard Myu when he goes to the Great Orcus Labyrinth to save his classmates.

During their fight against Freid Bagwa, Tio admitted her true love for Hajime before escaping per his orders. Since then, Hajime has become "slightly" more tolerant of her and sees Tio as a member of their group. He also has great respect for her wise decisions and being able to remain calm in situations that even Yue couldn't hold her composure.

This in addition to her always doing her best to get along with everyone and her superb insight, Hajime was forced to admit to himself that if it wasn't for her perverseness, she could be the perfect woman for him. However even when Tio was transformed into Super Tio, the graceful princess of dragonmen who was acting wise, Hajime himself said that he liked the perverted Tio and changed her back to her normal self by insulting her.

While initially Tio joined Hajime's party with the intention of using him to fight the gods that destroyed her country out of revenge, Tio soon fell in love with him and wanted to stay at his side. Tio's wish of using Hajime to achieve her revenge was known to Hajime which is why he had her aid him during his battle against Noint by defeating the Holy Church members (with some help from Aiko that were interfering in his fight with Noint) thus helping her achieve her revenge.

Hajime later confesses that he loves her when her grandfather and the rest of the dragon race decided to help him to wage war on Ehit. While Hajime's treatment and feelings have improved, he still doesn't hesitate to punish Tio like before, both out of affection and annoyance.

Shizuku Yaegashi
Hajime cannot handle Shizuku for she knows his secrets such as middle school chuni habits. Hajime regarded Shizuku as the most reliable of all his classmates. Hajime always had a positive opinion of Shizuku because she always helped him out before they were summoned to Tortus and didn't cause him any trouble, unlike Kaori.

Shizuku sympathized with Hajime's plight as the target of bullying by Hiyama and his gang as a result of Kaori's infatuation with him due to her similar circumstances in the past as Kouki's childhood friend. Even after his transformation, he still spoke with her more nicely compared to the rest of his classmates and was willing to help her out on many occasions, including giving her one of his masterpieces, a new enchanted Black Blade Katana that works better for her fighting style and consoling her after Kaori's death.

The way he got along with Shizuku caused Yue to see her as "the last boss", who she and Kaori might have to go up against for Hajime's feelings. After reviving Kaori, Shizuku owed Hajime a great debt for saving her best friend. After conquering the trials in the true Haltina Labyrinth, Shizuku couldn't stop thinking about Hajime due to her own preferences for men that she can rely on, in addition to her living an illusion where Hajime is her prince.

After Hajime saved Shizuku from being killed by her Frost Caverns of Schnee doppelganger and also gave her encouragement to accept her negative feelings that allow her to defeat her doppelganger, it cemented Shizuku's resolve to pursue her love for Hajime. Happily accepting a hand-crafted hair clip type restoration Magic Artifact from Hajime as his second present to her, Shizuku peacefully slept on Hajime's back as he carried her to find the others.

After Hajime stopped a corrupted Kouki's rampage without killing him, with gratitude and love, Shizuku affectionately kissed Hajime, confessing her love for him, and she will do anything to become his lover which Hajime silently accepted and did not reject compared to the time he received Kaori's love confession, given how he has already decided to practise polygamy with the other women of his harem.

After returned to Japan, Shizuku became one of Hajime's wives. Unfortunately, her so-called "fans" of the "Soul Sisters" (who are actually her annoyances) failed to try to break her up with Hajime and the students of her family's dojo failed at attacking Hajime only for both these groups to be easily defeated and completely humiliated by Hajime which after they caused misfortune to Shizuku.

Aiko Hatayama
His homeroom teacher who was transported to Tortus along with her students. At first, she thinks of him as one of the students that she cares for. She feels very responsible for his apparent death and does whatever she can to protect her students, even using herself as a bargaining chip.

Later, after Hajime had killed Shimizu, knowing that he had done it for her sake, she becomes conscious of him as a member of the opposite sex. She later comes to accept that she loves him after he saved her from Noint and he comforts her after she and Tio destroyed the Holy Church and killed all the people inside, although she's still troubled with the fact that she is older and his teacher.

However, Hajime later pointed out both of her problems are meaningless as he will stop being her student after he graduates high school and their age different is pretty pointless considering how much older Yue and Tio are in comparison.

Liliana S. B. Heiligh
The Crown Princess of the Heiligh Kingdom. She is one of the few people in Heiligh Kingdom who did not look down on Hajime due to his lack of combat skills and treated him kindly compared to everyone else in Heiligh Kingdom, who dismissed him as worthless.

When she found out that Hajime had survived and Kaori decided to travel with him, she tried to dissuade her father, the nobles, and the Holy Church from declaring Hajime a heretic so that both he and Kaori could have a place to return to, but to no avail. After her father and nobles started behaving oddly, she decided to leave the Heiligh Kingdom in secret to go searching for Kaori and Hajime to get help as they were the only people left she could trust.

Although she later learns that Hajime didn't care about the people of Tortus anymore, she was able to convince him to come back to the capital with her to save Aiko. At the Heiligh Kingdom, Hajime was able to defeat Noint and fighting the demon army who were invading the capital. Liliana is very grateful to Hajime for saving the capital and wanted him to stay as a deterrent against future demon attacks, which he refused but he compromised by repairing the capital's barrier.

After she managed to convince Hajime to drop her off in the Hoelscher Empire, she later grew angry and exasperated with Hajime due to him causing her trouble during her diplomatic trip. After Hajime's arachnea golem stopped Prince Baius attempt to rape her, Liliana became smitten with Hajime due to him rescuing her in her time of need. During the engagement ball, she asked Hajime if he could save her, and Hajime agreed due to her being one of Kaori's precious friends, causing Liliana to fall in love with him. After the “The Haulia Rebellion”, Liliana would attempt to get closer to Hajime but he would usually ignore her, causing her to become tearful.

In the After Story, it is revealed that Liliana succeeded in getting Hajime to fall in love with her. When Hajime returns to Tortus, he takes Liliana back with him to Earth with the blessing from her subjects, as they had originally believed she had eloped with Hajime and their desire to see the princess who they care for happy. She is very happy when he flirts with her and spoils her, blushing when it seems apparent that the two of them would become physically intimate. Hajime is the first to notice Liliana's workaholic habits and tries to help her get rid of them.

Myu
Hajime and Shea saved her from a sewage system after she escaped from slavers. Myu immediately bonded with them and began to call them "Onii-chan" and "Onee-chan". Later on, after Hajime and the others once again saved her from slavery she began calling him "Papa" much to Hajime's chagrin. As they traveled together Hajime began acting more and more like her father, from being incredibly overprotective to scolding and subsequently comforting her when she put herself in danger. After returning Myu to her mother, Remia, who started referring to Hajime as her husband, Hajime decided to take them with him once he returns to his world which both mother and daughter happily agreed to.

Remia
Myu's Mother is one of Hajime's wives. Remia sees Hajime as a savior and a father figure for her daughter while falling in love with him as time progress. She even addresses him as "darling" several times when talking to him and enjoys acting as his wife while they are together but became his real wife after he brought her and Myu to Japan.

Shuu Nagumo and Sumire Nagumo
As their only son, Shuu and Sumire held immense love for Hajime which he also reciprocated, having inherited their Otaku passion and interests, earnestly assisted them in their work. When Hajime suffered from bullying, Shuu and Sumire allowed Hajime to make his own choice if he wished to transfer to another school to avoid bullying or stay on.

Hajime would frequently discuss with his parents about their otaku interest including what would happen if he were to be summoned to another world which ironically came true when Hajime was summoned by Ehit to Tortus. When Hajime fell into the depths of the Great Orcus Labyrinth and lost his left arm and later his right eye, it was ultimately his desire to reunite with his parents again that gave him the resolve and willpower to fight and conquered the dangers of the Great Orcus Dungeon, doing everything in his abilities to become strong enough to survive and getting back home, doing so with immense conviction, even if it means becoming a genocidal mass murderer or even a god slaying destroyer as Shizuku had correctly predicted in Volume 8 ,when Hajime actually slayed Ehit while in his journey to returned home back to his parents.

Cam Haulia
The relationship between the two is complicated to say the least. Hajime respects him as a father in law but has trouble with his chuuni actions and the fact that Cam sees him as his superior officer.

Lundel S. B. Heiligh
Liliana's younger brother and the Crown Prince of Heiligh Kingdom. Lundel hates Hajime for "stealing" Kaori from him and seducing his sister who he respects. He always challenges Hajime to a fight only to be hit by Hajime with a sugar cube while Hajime himself finds Lundel's attempts humorous and interesting.

Luluaria S. B. Heiligh
Liliana's mother. She is grateful to Hajime who saved her kingdom and the world of Tortus from Ehit. When Liliana returned from the Empire and complained about Hajime, Luluaria got into high spirits unbecoming for her age. She is happy that Liliana found love since she feels guilty about how much Liliana has done for the kingdom including offering herself to marry Baius D. Hoelscher for the sake of having the Empire help the Kingdom despite her own misgivings about him and her maidenly desire to find love. However, she is worried about her daughter's habit of working too hard for the sake of the kingdom and how she would not be able to build a good marriage life. She is one of the few people that Hajime talks with respectfully.

Adul Klarus
Tio's grandfather and leader of the dragon clan. Hajime meet him before the final battle against Ehit. Hajime treated him respectfully and apologized for turning Tio into a pervert, resolving to receive a punch from him before the final battle begun. Adul, although shocked by his granddaughter's transformation, accepted it.

He asked Hajime if he truly loved Tio, as Adul wouldn't allow Tio to risk her own life by going into the Holy Precincts with unclear feelings. Hajime answers that while he is in love with Yue, he also loves Tio. Satisfied with his answer, Adul asks that Hajime take care of Tio, to which Hajime promises to take care of her until the end of his life.

Adul is grateful to Hajime that Tio has found her happiness. During the final battle, he witnesses and compliments Hajime's power while expressing amazement at Hajime's artifacts that strengthened him. Adul is one of the few people Hajime treats respectfully and is the person he respects most among the adults that he knows, so much so that Hajime's own father became jealous of their interaction.

Whenever Adul witnesses Tio's happiness or gets complemented by Hajime and Myu, he loses his imposing dignified aura, instead transforming into a good-natured old man.

Tomoichi Shirasaki
Kaori's father. Hajime relationship with Tomoichi can best be described as complicated due to the latter being too doting towards his daughter. Most of the time, Tomoichi is hostile towards Hajime because he's dating Kaori, while also having a harem. Hajime understands Tomoichi's feelings on this well enough to admit he would feel the same way if something similar happened to his own daughter Myu.

At the same time, Tomoichi is grateful to Hajime for protecting his daughter and bringing her home, something he's willing to admit. There are also times where Tomoichi can sympathize with Hajime when it comes to being a father and is willing to lend his experience to him, such as when it comes to dealing with an angry daughter or being confined by their respected wives (Kaori and Kaoruko). Other times, Tomoichi is usually amazed or disturbed by Hajime's artifacts.

Kaoruko Shirasaki
Kaori's mother. She is more openly supportive of Kaori's relationship with Hajime than her husband.

Yaegashi Family
Hajime has a complex relationship with the Yaegashi family. While they are grateful to Hajime for protecting Shizuku and allowing her to be more honest with herself by being more girly, they also repeatedly attack Hajime everytime when he visits Shizuku's Dojo and due to him having a harem while proclaiming himself as Shizuku's lover. Nevertheless, Hajime bears no ill will towards them and gets along with them although he sympathizes with Shizuku when her family's secret ninja habits become a bother to deal with. They also have a lot of interest in Hajime's artifacts and have made some request for them, such as him building them a secret underground space for them or selling them a Neuralyzer New.

Ehit (Deceased)
Hajime is Ehit's latest archenemy and killer.

Orginally, Ehit was the God of Tortus that summoned Hajime and his classmates to serve as pawns in his game for his own amusement. At first, Hajime had an instinctive fear of Ehit when he saw his portrait in the Holy Church. Later, Hajime learns of Ehit's true evil nature through the projection of Oscar Orcus and how he manipulated the world in order to stop the Liberators uprising against him as well as his continuous manipulation of all living beings of Tortus. For this, Hajime abandoned all of his respects for Ehit for selfishly summoning him to Tortus for his twisted entertainment and hates all of the gods as he swear that he will kill them all if they dared to get in his way.

Despite his newfound hatred for Ehit, Hajime at first had no intention of carrying out the Liberators mission of destroying Ehit, preferring to focus on obtaining Ancient Magic for the sake of returning to Earth with his companions. Due to being the only one alongside Yue to have learned of Ehit's true nature in the Great Orcus Labyrinth, Hajime had come under Ehit's notice as Hajime had refused to obey the god's creed as one of his so called chosen heroes by rejoining his classmates and to aid the Holy Church in the war against Demons.

Having foreseen Ehit's schemes through the Liberators past defeat, Hajime had tried to warn Aiko about Ehit's true nature in order to prevent his classmates under Kouki's delusional pride and leadership to come after him under the evil god's manipulation as well as the fact Hajime had prevented tragedies stemming from Ehit's instigation of the Demons such as saving the Lake Town of Ur as well as the Dukedom of Ankaji. Seeing his new change, Ehit fears Hajime more than the Liberators and considers him "Irregular" and wishes to remove him from the game board as he has become too powerful and disruptive to his plans as his greatest pawns: the Holy Church, the Heiligh Kingdom and his other chosen heroes including Kouki himself could do nothing against Hajime, thus sending his Apostle Noint to assassinate him. However when Hajime killed Noint and used her corpse to revive Kaori as an insult to the God, Ehit is shown in both fear and rage.

With the help of his teacher Aiko and princess Liliana of managing to reveal the truth, Hajime has successfully made the human worshipers who were once devoted to Ehit, turning against him after learned they were being used as playthings.

When Tio revealed to Hajime that Ehit was responsible of her parents and people's deaths, Hajime decided to fulfill Tio's wish to kill Ehit.

However when Ehit's pawns notice that Yue (Ehit's long lost desired host was Hajime's companion) he changed his plans and focused on securing Yue as his host body. Knowing that Hajime and Yue are powerful enough to clear the remaining Labyrinths, Ehit decided to wait until Yue managed to acquire all of the Ancient Magic to possess her as he sent all his Apostles to aid Freid in capturing all of Hajime's classmates as well as Myu and Remia so they would serve as hostages until Hajime foiled it. Hajime then fought Ehit while in control over Yue's body until she broke free from his control and allowed him to kill Ehit to put an end to his game forever. During their battle, it also became even more insulting for Ehit when he realized that while Hajime was aiming to kill him, it was not to save Tortus from his manipulation like the Liberators and Kouki wanted to, but simply because Ehit was just another enemy for him to kill for standing in his way and to avenge Tio's people.

Heiligh Kingdom and Holy Church (Formerly)
When his class was first summoned by Ehit, Hajime was mistreated by the Heiligh Kingdom nobility for being the weakest member of the Hero Party. The Holy Church and the king however weren't rude to him, but they did not think much about Hajime either. From his "fall", they thought of him being dead since he was weak, although the king and the Holy Church are shown to be respectful with Hajime's supposed death while the other nobles showed delight and spoke ill of Hajime without caring about the sadness of some of his classmates.

When Hajime survived the fall and reunited with Aiko and his classmates as a completely changed person and saved the town of Ur, the knights reported the news about this. The nobles were shocked and angered when they heard that Hajime was still alive, and they also did not believe that his transformation had changed anything, while the king and the Holy Church also believed the same. However, after hearing the news that Hajime possesses overwhelming strength that completely surpassed his blessed classmates, along with the successful job of destroying an enormous horde of monsters, and that he had created very powerful weapons, the nobles along with the King and the Holy Church retracted their bad talk of Hajime, and began to take an interest in him, since the weapons and artifacts that Hajime had manufactured as well as the latter himself could serve them better in future wars against Demons. However, after Hajime had refused to return to the Hero Party and stated that he does not care about the lives of the people in Tortus anymore, the Holy Church called Hajime and his party "heretics". They tried to kill Hajime and his companions in the name of their "god" by sending Noint to assassinate him only for Hajime and his companions to destroy many of the Heiligh Kingdom's knights (who were controlled by Eri) and the Holy Church's pope and his bishops (who were destroyed by Tio and Aiko for their interference with Hajime's fight with Noint.)

Currently, Hajime holds complete disloyalty towards the Heiligh Kingdom and Holy Church and didn't care about being considered along with his companions as so-called "heretics" due to not only his survival, but his demonic power. Hajime doesn't hold any qualms about destroying the Holy Church and half of the kingdom itself by using his satellite laser to extinguish 100,000 of Freid's troops as he stated that he was never affiliated with the Heiligh Kingdom or his classmates and called the latter a fool along with refusing to reveal the location of the Labyrinth to the demon.

After revealing the truth of Ehit's true nature as an evil "god" thanks to the help of Aiko and Princess Liliana, not only did the kingdom stopped being his enemies but also turned against Ehit for his manipulation and cruelty towards them by joining Hajime's side to destroy Ehit much to his fears. In spite of this, Hajime is still disloyal towards them and will destroy both of them and erase them from existence if they continue to become his enemies.

Freid Bagwa (Deceased)
The Grand Commander of the demon army in Garland as well as a Ancient Magic user. Freid became aware of Hajime's existence when Hajime foiled the demon invasion of Ur and the ambush of the "Hero Party" in the Great Orcus Labyrinth, in which his subordinate Cattleya lost her life. Seeing that Hajime kept interfering in his plans, Freid went to the Grand Gruen Volcano to obtain it's Ancient Magic in order to become stronger for his confrontation with Hajime. Freid managed to ambush Hajime at the Grand Gruen Volcano, but was unable to defeat him as Hajime, despite his injuries managed to fight back against Freid, injuring him in turn thus forcing him to retreat.

Freid faced Hajime again during the demon invasion of the Heiligh Kingdom, as he tried to ambush Hajime and trying to take his classmates hostage, mistakenly believing that Hajime was fighting for the Kingdom and that he thought that he could make Hajime surrender by using his classmates as hostages to force Hajime to give him the locations of the Labyrinths. Hajime scoffed at him, as he wiped out 100,000 of Freid's monster army with his Hyperion satellite laser weapon before calling Freid a fool and refused to give him the locations of the Labyrinths for his ignorance as well threatening to kill him and destroy the rest of his army unless he retreated. Though furious, Freid did not want to waste his comrades lives though he swore in the name of his God that he would kill Hajime the next time they meet as he retreats.

Cattleya (Deceased)
Hajime is Cattleya's murderer.

When Hajime arrived, he told Cattleya to leave or to die. She choose to fight him out of anger until her army were defeated. When seeing he felt nothing from her strongest attack, Cattleya asked Hajime if he is human which in response Hajime told the demon woman that he was once, but is no longer causing her to call him a monster. Hajime questioned her if the monsters were actually from ancient magic when clearing the labyrinth which Cattleya realized Hajime cleared a Great Labyrinth and understood that if he is anything like the monsters, his monstrous and inhuman strength were checked out which got all of Hajime's answers. After their conversation, Cattleya tells Hajime to shoot her but warned that her lover will avenge her one day which Hajime doesn't care who his enemies would be either demon or god as he told her he will kill them all. Hajime then shot her at the head while disregarding Kouki's pleas causing most of his classmates to be terrified of him.

Noint (Formerly)
Hajime was Noint's would-be assassination target, killer and reviver.

When Ehit sent Noint, his top apostle to assassinate him, Hajime wasn't impressed with her. He mocked Noint during their fight as being more than she can handle. Hajime ultimately killed Noint after a long battle and later used her corpse as a vessel to revive Kaori with spirit magic, after she was killed by Daisuke to both save her and to insult the evil god Ehit. After returning Kaori back into her original body, Hajime kept Noint's body to any case if Kaori dies, he will revive her with Noint's body over and over again.

After Hajime revived Kaori with Noint's body, the former apostle transferred her spirit to one of Hajime's spider golems along with Hearst and renamed herself Netemp. Eventually she decided to become a loyal subordinate to him.

Hearst (Formerly)
One of the apostles present during the decisive battle. After getting killed by Shea, she joined Noint in one of Hajime's spider golems and renamed herself Etemp

Garland
Hajime and his companions are deemed to be the greatest threats and the most wanted "heretics" to Demons and their land after not only he and his party murdered Cattleya (who was following orders to recruit the "Hero Party" or kill them if they refuse) and Mikhail, but his disrespect for their god. When the demon commander, Freid Bagwa and his troops invaded the Heiligh Kingdom, Hajime wiped out 100,000 intitial troops and threatend to kill more if they don't retreat. Later under the plan of Eri, the Garland tried to capture Remia and her daughter, Myu to use them as hostages only to be foiled by Hajime.

Alv (deceased)
Hajime is the killer of the so-called "god" of the demon race. Said "god" was the demon lord of Garland possessing the body of Yue's deceased uncle.

When confronting him after failed to try to capture Remia and Myu to use them as hostages, Hajime trapped Alv into a small cage using concept magic and tortured him to give him the location for Yue. When the severely injured Alv begged Hajime to spare him, saying that he will be a completely loyal servant or guide to lead him to Yue, only for Hajime to ruthlessly kill him by shrinking the cage and Alv to non-existence.

Daisuke Hiyama (Deceased)
Hajime's former bully from the past, but now his direct killed victim. Before being summoned to Tortus and falling into the abyss, Daisuke and his gang bullied Hajime for preventing Kaori Shirasaki to fall in love with him. Daisuke secretly betrayed his classmates by his attempted murder on Hajime but only to become a very powerful mass murderer.

After Hajime survived and became a ruthless murderer, Daisuke became terrified of him because of his monstrous strength when he massacred many monsters and Cattleya with ease. When Hajime gave a warning to Kouki that even they were former classmates, he will murder anyone who gets in his way, and when he defeated Kouki in an unarmed duel, Daisuke is shown in fear that he is now no match for Hajime.

When Hajime and his party prepare to leave while Kaori joining him, Daisuke attempted to manipulate Hajime by feigning his apology to him and tries to "convince" Hajime to forget what he have done to him and his mistreatment in the past in order for Hajime to rejoin the Hero Party (just so he could get close to Kaori). But for Hajime, he doesn't care about his previously mistreatment as it doesn't hold any means to him anymore and refused to return to the party by calling Daisuke and his gang worthless and weak as he see madness in Hiyama's eyes as well as he subtlety exposed hints of Daisuke's attack that caused him to fall into the Abyss. He even warned them to stay out of his way if they wishes to live, causing them to become terrified of Hajime.

After Daisuke has revealed his betrayal and temporarily murdered Kaori, the enraged Hajime fought Daisuke and overpowered him with ease. While Hajime gripped Hiyama's neck, he tormented and beating up his former bully as he called Daisuke a weak selfish loser due to his lack of responsibility and always enjoying inflicting pain on people which is the main reason Kaori will never become his girlfriend for the rest of his worthless life. Hiyama's downfall was that he blamed Hajime for getting attention from Kaori, and he insolently bragged his final words of how he persistently will kill Hajime and make Kaori his girlfriend one day. When Hajime heard that, he has brutalized Hiyama even further and he put the nearly broken boned and organ damaged Daisuke out of his misery by kicking him out to the courtyard filled with a horde of upcoming Demons and watched pitilessly as the Demons devouring Hiyama. With this, Hajime got his vengeance for Daisuke's betrayal thus not only avenging Kaori but also his fall into the bottom of the abyss.

After murdering Hiyama, he made this murder a lesson to his other classmates of what would happen if any of them dares to cross him and break his absolute warning by harming one of his companions. This caused his former classmates and former bullies who were now terrified of his ruthlessness and demonic strength such as Shinji Nakano and Yoshiki Saitou, to repent in front of Hajime and swear to never get in his way but finds them still annoying. Hajime also scolded Kouki for his naive expectations that his classmates are naturally obligated to help and protect each other just because they are classmates only to allow the traitorous idiot, Hiyama and the intelligent Eri to betray him without him ever noticing it. Every single one of Hajime's former classmates held bitter memories of hating Hiyama for his arrogance and treachery from both in school and Tortus. Kouki was the only one who condemned Hajime for Hiyama's death.

In the After Story roughly 6-7 years after returning from Tortus, Hiyama's family tried to get revenge on Hajime only for him to easily defeat them. Though this was because they were unaware of Hiyama's betrayal and temporary murder of Kaori. They have also suffered an extreme breakdown after this.

Eri Nakamura (Deceased)
One of Hajime's classmates who was also a traitor working for Garland as a spy.

It is unknown of how Eri personally felt for him, but was willing to kill him and the rest of their classmates due to them being her way to make Kouki hers. Like Hiyama, Eri is also terrified of not only Hajime's survival but his monstrous strength and murderous intent when he killed Cattleya. Upon his arrival during the Demon invasion, Hajime prevented Eri's "Blind Soul" from turning Kaori into Daisuke Hiyama's undead slave. When the enraged Hajime marched toward Eri following Kaori's temporarily death, Eri showed her fear of Hajime as she begged her demonic classmate to spare her life in exchange for making Kaori his undead slave, though is only made Hajime expressed an even greater rage as he has no need for Eri to do that, because he had already acquired Spirit Magic and was willing to kill her. Eri sent her undead soldiers to attack Hajime only for them to be easily destroyed by him. She then tried to attack him with daggers only for him to easily overpower her and tormented her worse than what her mother and stepfather did with her in the past. She feared the worse when Hajime was prepared to kill her, while disregarding whatever reasons and motives she had for her betrayal but was prevented by Hiyama's interference when he attacked Hajime with a fireball despite Eri having already betrayed Hiyama. After Hiyama's death, she got away with Fried when he retreated. In Garland, she suggests that Remia and Myu will be good hostages against Hajime which is too predictable as Hajime know of her plans. Later when Eri captured Yue and presented her body to Ehit, Hajime has shown to be enraged as he will kill Eri for taking Yue away from him since she dashed away her only chance for redemption. Though he seems no longer needed to do that when Eri died by committing suicide in an attempt to kill Suzu in the final battle.

Soul Sisters
Hajime is the "Soul Sisters'" sworn enemy and bully as well as the annoyance of his wife, Shizuku.

For the failed attempted to force Hajime to break up with Shizuku and their constant harassment of him, Hajime easily repelled and bullied the Soul Sisters by grabbing one of them by the neck to force her to drink his laxative before tying up her ponytail hair even using a permanent marker on her face to humiliate her and entire "Soul Sisters" at the wedding photo shoot as a warning if they challenged him again. After gotten humiliated by him, everyone were laughing at them at school much of their embarrassments.

Yaegashi Family Dojo's students
The students of the Yaegashi's Dojo are extremely jealous of Hajime for marrying Shizuku and continually attack him every time he visited the Dojo, because of their persistent stubbornness, only for Hajime defeated them all with ease, while he isn't impressed by the students.

Helmut (Deceased)
The evil dragon from a world of dragons. Hajime effortlessly defeated him by using the "hostages method", causing the people below, enemies and allies alike, to view him as a demon god.

MOTHER (A.I.) (Deceased)
The A.I. and self-proclaimed goddess who fought against Hajime and Kouki in a sci-fi world. It was thanks to him that Mother gets agitated pretty easily despite normally being calm and composed. After being defeated by him and his overwhelming army of Grim Reapers and so on, she was terminated by G10.

Freidhof (Disbanded)
After captured Myu and attempted to sell her and the beastman little girls as slaves, Hajime and his party murdered the dealers including their leader and later destroyed all of their hideouts to put an end to slave trades forever.

Crystabel and his manly women squad
Unlike with the rest of his enemies, Hajime sees them as more of annoying people and if it weren't for Yue and the rest of his party, he would have "massacred" them already. Crystabel and the group do not have any ill-intentions against him, which makes it harder for Hajime to kill them.

Hajime's Party
Hajime is the leader of his own party which initially only consisted of himself and Yue after they escaped the Abyss and were later joined by Shea, Tio and Kaori. He cares very deeply for his comrades but was insistent at first because he only loved Yue in a romantic way but that changed when Shea managed to get Hajime to acknowledge and accept her love for him too which lead him to accept Tio and Kaori's love as well. Since all the members in his party are beautiful women, Hajime often has to chase away and fend off men who wish to seduce them, sometimes even threatening them and using violence to keep them away from his harem.

Due to his protective nature, Hajime has fierce determination to protect his comrades and does whatever he can to keep them happy and satisfied as was demonstrated when he protected Shea's Haulia Tribe and help them take down the Hoelscher Empire when they tried to capture the Haulia or when he promised to fight Ehit on Tio and her tribe's behalf. However if one of them is harmed, Hajime shows his wrath by killing those who harmed them just like he murdered the traitor, Hiyama for temporarily murdered Kaori. Hajime willing to do anything to revive one of his comrades with spirit magic and transferred their soul within Noint's body as he revived Kaori for the sake of her best friend, Shizuku (who indebted Hajime and later also fell in love with him). Hajime wins many of their hearts and became popular with beautiful women even more than Kouki.

On the other hand, his female companions are absolutely loyal to Hajime due their love for him and support his desire to return home to Japan even if it means leaving their own home in Tortus and people they care for. They often competing against each other in order to seduce Hajime and want to further their relationships with him even willing to have sex with him and becoming very happy when he compliments them or ogles them, becoming very happy and excited when he does anything lewd to them or when they have sex, as Yue and Shea demonstrated. Due to their absolute love for him, they always ignore other men attempt to hit on or seduce them, frequently becoming annoyed when they approach (such as Kouki).

In the After Story, Hajime married all his female comrades and became Myu's father as he builds a stable family life with them and deepens his love for them.

Yuka Sonobe
Yuka is one of Hajime's classmates who was transported to Tortus. Yuka is grateful to Hajime for saving her life in the Great Orcus Labyrinth from the Traum Soldiers and wishes to pay him back. She is shown to have a crush on him as time passes. The two of them get along to the point that most of the other students in her class call her his 'Mistress' (though they both deny any romantic involvement between each other). Hajime has admitted he trusts Yuka and feels comfortable talking to her about his problems.

Helina
Princess Liliana's former personal maid. She now serves Hajime as the leader of the Fleur Knights combat maid group. Helina is shown to treat Hajime as more of her master than even Liliana as she enjoys serving him and the two of them have a proper relationship of master and servant. Hajime is shown to prioritize Helina's instructions rather then Liliana's wishes, which annoys Liliana as her husband is listening to her maid despite Liliana's status as a princess. Helina was responsible for helping Hajime create the Fleur Knights by scouting out various members for the group. Hajime appointed her as the maid leader of the Fleur Knights.

Fleur Knights
The Fleur Knights are Hajime's female students and combat maids. Hajime assigned them to protect Princess Liliana S. B. Heiligh with their lives. The Fleur Knights are absolutely loyal to Hajime and will execute every mission he assigned them without hesitations.

Kousuke Endou
He is one of Hajime's closest friends and he is considered as the 'Right-Hand of the Demon King'. Though Kousuke didn't used to have much interaction with him before the 'Summoning Incident', he was still affected by Hajime's supposed death in Great Orcus Labyrinth. But after learning that he was still alive, and learned about his journey and how he was able to overcame all the odds, Kousuke started to have respect towards him, especially after Hajime helped him rescue his friends who were ambushed in the Great Orcus Labyrinth. Later on, after the climactic battle, as Kousuke was entranced by Lana, he went on to ask her out repeatedly. After countless attempts, Lana gave him the condition of clearing a Great Labyrinth and landing one hit on their boss, a.k.a. Hajime, before she would consider going out with him. Kousuke managed to achieve both of them, and Hajime has since then respect for him. After the students return back to Japan, Kousuke becomes the only member of the Returnee's group who stays active and does various tasks for and with Hajime in order to protect and manage the safety of everyone close to them. Because of Lana's nature of wanting to gather 7 wives for Kousuke, and the fact that the "Abyss Lord" powers of Kousuke turned him into a, Hajime started to have a really close relationship with Kousuke and even considering him as a 'bosom friend'. Hajime also starts to egg Lana on her quest for a harem for Kousuke. This has resulted in many complicated situations for Kousuke, as a result.

Meld Loggins (Deceased)
The former Knight Commander of the Heiligh Kingdom that was entrusted with the responsibility for overseeing the training of the summoned heroes from the other world. While Hajime wasn't as close to Meld as the frontliners of his class, he always respected the captain, even after his transformation. This make Meld one of the few adults in Tortus who Hajime truly respected and still speaks highly of him to this day. Hajime was willing to use one of his Ambrosia to save Meld's life after he came to rescue him and the hero party at the Great Orcus Labyrinth, admitting he didn't want him to die. Meld on his part was grateful that Hajime saved him and the others, happy that Hajime had survived and regretful that he failed to save him before. Hajime becomes saddened when he learned that Meld was killed as he granted him permanent peace by destroying his corpse that Eri was controlling with her necromancy. Hajime later visited Meld's grave to leave a flower a token of remembrance and honor him.

Riiman
Riiman is considered to be Hajime's first male friend since he was summoned to Tortus. The two of them instantly bonded when they first met at the aquarium where Riiman was being held.

Kouki Amanogawa
Hajime has a neutral standing about Kouki and ignores the fact that Kouki envies him. He only has a little bit of good intent to Kouki because he is a close friend of Kaori and Shizuku. However Hajime mostly considers Kouki to be a large nuisance for him to deal with because of the latter's bad habit of only believing what fits his own worldview and his annoying sense of justice even after Kouki had failed so many times because of it. Hajime even preferred not to explain to Kouki about Ehit's true nature as an evil god and his schemes in summoning their class to Tortus as pawns for his mad death game because he knew Kouki would never wanted to believe him given Kouki's delusional idealism, immense pride as Ehit's so called chosen hero of Tortus, and the glory of all the hero worship he had received from Ehit's worshipers of the Holy Church and the Heiligh Kingdom fueling his ego. While Kouki one-sidedly sees Hajime as a rival, Hajime sees Kouki as an masochist hero and a immature, stubborn and spoiled brat with grand words lost in his own delusions.

As a former member of the "Hero Party", who had learned about Ehit's true nature as well as having become powerful enough to survive on his own in Tortus, Hajime refuses to take orders from Kouki anymore as he was deeply annoyed by the latter's self-righteous naive beliefs and his delusional pride of being Ehit's chosen hero which makes Kouki think that he have the right to enforce his misguided justice upon Hajime and his friends. When Hajime's comrades are greatly annoyed and disgusted by Kouki's insolence, Kouki self-righteously challenged Hajime to an unarmed duel to claim his comrades by force only to be easily defeated and humiliated by Hajime when he tossed the "hero" into a pitfall filled with non-lethal grenades to end such a pointless duel.

After Hajime murdered Hiyama and Aiko exposed Ehit's true evil nature and his schemes to his classmates, Kouki stubbornly tried to blame Hajime for Fried's invasion and Eri's betrayal by not warning them earlier about Ehit. Hajime scolded Kouki for his delusional justice and idealism that really caused it such as his naive expectations that his classmates are naturally obligated to help and protect each other, which are the very weaknesses that allowed both the intelligent, Eri and the treacherous idiot, Hiyama to betray him without even noticing until it was too late. Hajime also coldly criticized Kouki's lack of resolve, that led to all his failures during the important moments despite originally being the strongest of them, when Kouki berated him for refusing to use his new found powers of Ancient Magic for "justice" as that is not what Hajime wanted, rather as what he desired is to use the power of "Age of Gods" magic to return to Japan. Hajime even disparaged Kouki's delusional heroic beliefs to be ridiculous and childish, telling him that strength is nothing more than a curse if one must be obligated to do things simply because they have power to do so regardless of their own personal wishes.

Hajime also threatened to kill Kouki out of annoyance of his persistent naive idealism but he gave him a chance to join him in clearing the remaining Great Labyrinths and to gain Age of God's Magic due to Suzu, Shizuku and Ryutarou's pleas.

Even though Hajime saved him and the rest of his classmates twice already, Kouki still couldn't accept Hajime's choices to abandon the people of Tortus to their own fate under Ehit's tyranny because it contradicts his own ideals. Unlike Ryutarou and Shizuku who appreciated Hajime for reviving Kaori, Kouki was the only one who doesn't expressed his gratitude to Hajime due to both his jealousy and his stubborn adherence to his misguided self-righteousness and delusional justice. However Hajime disregards all of Kouki's complaints to be nothing but empty words due to Kouki himself continuously failing during the truly desperate moments, such as Cattleya's ambush and Eri's death trap, because of his indecisiveness getting the better of himself despite having been blessed by Ehit as the strongest of their class at the beginning along with repeatedly proclaiming that he would save and protect everyone. Out of all of his classmates who retained their bitter memories of their hatred towards Hiyama for his arrogance and betrayal, Kouki was the only one who condemned Hajime despite Hiyama was a traitor due to Kouki's naively and delusional sense of "justice".

Due to Hajime's new wild appearance, Kouki became more jealous of Hajime's ability of getting a harem of more beautiful girls (including Kaori and later also Shizuku), while he himself lost all of his popularity for girls completely after Hajime won their hearts. Kouki even furiously questioned why Hajime is the only one who has a harem when he himself doesn't have one.

Hajime also outright told Kouki in both the Heiligh Kingdom and again in the Hoelscher Empire that he himself doesn't care about Kouki's misguided justice by clearly stating that they are neither friends nor comrades and certainly do not believe in the same ideology. Hajime also clearly stated he himself is not obliged to do things the way Kouki wanted like Shizuku and Ryutarou had and if Kouki continues trying to enforce his stupid justice on to him then Hajime will break his arms and legs before sending him back to the Heiligh Kingdom.

During their final trial in the Frost Caverns of Schnee, Kouki was corrupted by his doppelganger and he decided to try killing Hajime in order take the former's harem for himself and continue his pointless heroic crusade as Ehit's chosen hero. Hajime finally lost his patience with Kouki's delusions and thus brutally retaliated by shooting both of Kouki's kneecaps and ruthlessly thrashing him. He also sharply criticized the "hero" that the reason why he failed at everything he did in Tortus up until their second fight is because of his foolish choice to constantly prioritize both his delusional pride and naive justice over everything else, especially the realization of his own goals. It got even worse when Kouki said Yue's name without honorifics, and Hajime brutalized Kouki further due to him having no right to say the name that he gave to his lover. Hajime initially wanted to kill Kouki to prevent another similar situation from occurring again but chose to spare his life for Shizuku and Kaori's sake by separating him from his doppelganger and killing it before punching the latter unconscious, thereby ending another hopeless fight.

Later, in the After Story, however, Kouki has trouble sorting out his feelings towards Hajime as due to his past actions and failures, and therefore could not bring himself to be angry at Hajime but is rather disappointed at himself for being so completely indecisive and not strong enough to realize his ideals. When the "Dark Beings" attacked, he thought about asking Hajime to transport the "Dark Beings" to another world, so that the people of Synclea Kingdom could be safe and the "Dark Beings" could survive without harming others. He was reminded of Hajime's way of prioritizing those close to him when he heard Koone's wish to save her sister above all. When Kouki was about to escape from Arquette that was attacked by the "Dark Beings", he thought about how he wanted to meet Hajime again along with his family and friends.

After defeating the "Dark Beings" that were attacking Arquette, Kouki resolved himself to fight for the sake of what he believed while accepting everything in contrast to Hajime's view of dividing the world between enemy and ally. Kouki and Hajime finally reunited when Kouki was about to be attacked by a pack of "Dark Beings", as Hajime dispatched them. Hajime then asked Kouki to go back with him but Kouki refused as he wanted to save Moana. Thinking that Kouki's delusional hero complex has returned, Hajime said that he would call Shizuku to give him a lecture but Kouki resolved himself to stay to save Moana. After the rest of Kouki's friends left the decision of Kouki's retrieval to Hajime, he wanted to confirm if Kouki thought that his choice was correct to himself, to which Kouki responded that such a thing didn't matter, an answer that impressed Hajime. Hajime then went to defend Arquette so Kouki could save Moana as he sent Kouki off with the aid of griffon Grim Reapers. When asked by the others why Hajime lent Kouki his aid instead of dragging him back, it is revealed that Hajime was curious as to where Kouki (who has obtained an answer which is the opposite of Hajime) is going to end up. After helping defeat the "Dark Beings", Hajime was willing to grant Kouki's request of taking Moana with him.

Right after saving the world, however, Kouki was again summoned into another world, dragging Hajime along with him. It turned out that both were summoned into a sci-fi world by the combat-support A.I. G10 by coincidence. During their time in the other world, both of them worked together when both of them were summoned into another world, where they fought against an evil A.I. with the help of G10, Kousuke (who was summoned by Mother), Noint/Netemp, and Jasper.

After defeating Mother, however, Kouki got summoned again, this time by an actual goddess, while dragging Hajime and Kousuke with him, similar to the previous summoning.

Classmates/Returnees
Hajime was originally not on good terms with most of his classmates due to being an otaku. The only classmates who were friends with him were Kaori (who had a crush since she first saw him) and Shizuku (being Kaori's best friend). Unfortunately, Kaori loving him caused most of the guys in the class to be jealous of Hajime and some of them bullied him at some point, mainly Daisuke Hiyama and his gang.

After they were summoned to Tortus, Hajime ended up having the lowest stats among them, causing almost everyone of them to call him incompetent. During the class training exercise in the Great Orcus Labyrinth, Hajime was the one who saved everyone by holding back the Behemoth long enough for them to get back, earning most of his classmates respect. Unfortunately, Hajime ended up falling into the abyss when he tried to retreat due to Hiyama's attack, which devastated most of them. It was because of witnessing what happened to Hajime had caused most of them to become too scared to fight anymore.

However Hajime survived the fall and decided to focus on his own goals instead of returning to them, thereby severing his ties to his classmates except for Kaori and Shizuku whom he only cared about. Upon reuniting with his teacher and some of his classmates who were acting as her bodyguards, he bluntly told them he himself had already forgotten them already and coldly warned them to stay out of his way causing them to become scared of him, especially after shooting David with a rubber bullet and giving a death threat to Chase. When Kousuke Endou reunited with Hajime after escaping the Great Orcus Labyrinth and informing him about Cattelya's ambush, he was willing to leave rest of his classmates behind to die, even going as far as to say they were no different than strangers to him whose deaths are no concern of his, despite Kousuke begging Hajime to help. However after being told that Kaori was with them, Hajime decided to rescue them to repay Kaori's kindness to him. When he reunited with the rest of his classmates after rescuing them from Cattleya, his transformation caused most of them to have trouble recognizing him at first and they ended up expressing ingratitude for his rescue due to both Kouki's delusional sense of justice over his murder of Cattleya and Hiyama's hatred of him for gaining Kaori's affection that became worse than usual before being silenced by both Yue and himself for their insolence.

Hajime later made it a point to tell them he doesn't consider them his comrades and he would kill them if any of them dares to go against him for whatever reasons including basic morality, even holding Kouki at gunpoint for physical emphasis. Because of this, they become terrified of him. Some of them though were more understanding of Hajime's new cold disposition towards them due to recalling the fact that they had chosen to turn a blind eye towards Hiyama bullying him in Japan and in Tortus and thus ultimately didn't begrudge Hajime for not viewing them as comrades. Even when Fried tried taking them along with the Heiligh Kingdom as hostages to force Hajime into surrendering, Hajime only responded with cold disdain as he destroyed Freid's army of 100,000 monsters since he literally couldn't care less if all of his classmates were to die by Freid's hands.

After Hajime gave his warning to his former classmates, most of them have taken it seriously as they don't want to die at Hajime's hands (with the sole exception of Kouki). They became even more terrified of Hajime's wrath after witnessing how he brutally murdered Hiyama for the his betrayal when he temporarily killed Kaori, understanding what would happen to them if they dare to cross him like Daisuke did. When Aiko exposed Ehit's true nature and schemes to them which was what nearly led to their deaths by Hiyama and Eri's betrayal, all of them except for Kouki didn't dare to try blaming Hajime for not warning them about Ehit earlier. This is due to both their fear of Hajime and their silent agreement with his harsh but correct criticism of how it was their naivety and careless optimism that nearly costed them their lives in Eri and Daisuke's betrayals. None of them (except for Kouki due to his delusions) condemned Hajime when murdering Hiyama for his betrayal and temporarily murdered Kaori.

Hajime gave them a second chance to join him in conquering the remaining Great Labyrinths thanks to Suzu Taniguchi, Ryutarou Sakagami and Shizuku Yaegashi's sincere pleas but kept his warning that if they cross him or harm his comrades again, he won't be forgiving towards them and will kill them just like he killed Hiyama. When Hajime offered his classmates who are traveling with him, to enhance their weapons and armors with new abilities, they rushed over to him to hand him their equipment to be enhanced but he only failed with Suzu's bracelets as they were destroyed. To compensate Suzu for her loss, Hajime gave Suzu one of his masterpieces: a pair of twin iron fans as a gift. When Suzu pleaded Hajime to give Eri a chance of redemption, he obliged her pleas due to Kaori but told her that he'll kill Eri if she doesn't redeem herself.

For Kaori's sake, he also allowed a few of his classmates to train under him as he did to the Haulia Tribe when he was touched by Ryutarou Sakagami's momentum and respect for him, with Ryutarou considering Hajime a pupil of Ryutarou's idol "Gunnery Sgt. Hartman" and called him a friend. Despite saying he doesn't care about them anymore, Hajime still found himself saving them whenever their paths crossed which they were grateful for. Hajime was also willing to bring his classmates back to Japan after clearing the Labyrinths and destroying the evil god, Ehit. After returning to Japan, his classmates gave him nicknames, "God Slayer" and "Demon King" out of appreciation but also combined these two nicknames into one as the "God Slaying Demon King".

In the After Story, Hajime's relationship with his classmates has improved greatly as they know better than to get on his nerves. All of them respect him for everything he has done for them in Tortus and consider him to be their leader now instead of Kouki, calling him the Demon King in a friendly manner. However since they can only see Hajime as the "God Slaying Demon King" they knew from Tortus, they find the sight of him going to school normally and using polite language towards the teachers as so unfitting they can barely keep themselves from laughing, no matter how many times they see it.

Yoshiki Saitou and Shinji Nakano
Saitou and Nakano were once Hajime's bullies from the past.

When Hajime returned after surviving the Great Orcus Labyrinth and seeing he had obtained monstrous strength, they became terrified of him. They attempted to apologize for Hajime to forget the mistreatment he received from them and begged him to return to the "Hero Party", purely to get closer to Kaori, Hajime himself revealed to the Bastard Four that his mistreatment from them doesn't holds any means to him and considered them as weak and worthless, but also revealed Hiyama's failed attempted to kill him which caused them be more afraid of Hajime. After Hajime killed Hiyama and Kondou, they genuinely redeemed themselves and kneel to apologize to Hajime as they swore they will never get in his way or harming his comrades. After Ehit's death and returning to Japan, Saitou and Nakano started showing respect for Hajime, but he still finds them annoying.

Other Students from Different Classes
It is unknown how the other students from different classes in his school felt towards Hajime prior to the summoning incident, but possibly the boys are jealous of Hajime for gaining Kaori's attraction though the girls have unknown feelings for Hajime.

After returning to Japan, the beautiful school girls from different classes have flirted with the newly wildly attractive Hajime and fell instantly in love with him as they want to win his heart which caused a rivalry with Hajime's harem and each other. For the boys from different classes, they became extremely jealous of him as they attempted to attack Hajime but only for him to pulverize the other boys easily and caused them to be afraid of him.

Inaba
A rabbit that saw Hajime's battle with the claw bear in the Great Orcus Labyrinth and recognizes him as the lord of the floor. Gained true sentience after imbibing water from the God Crystal. Eventually they met, and Inaba became one of Hajime's allies.

Miledi Reisen
Hajime respected Milidi for her determination of resolve to oppose Ehit, but was extremely annoyed with Miledi's mischevious nature due to all the traps and taunting insults he faced in her Labyrinth, and was irritated at Miledi for imposing her own wishes overthrowing Ehit upon him which Hajime ironically furfilled later for the sake of his lovers Yue and Tio both who were hurt by Ehit.

Oscar Orcus
Out of all the Liberators, Hajime respect Oscar the most due to being fellow Synergists, and Oscar's Labyrinth and Ancient Magic was the first one Hajime conquered and attained which Hajime used Oscar's collection of historical documents, notes, alchemist tools and artifacts in his hidden lair to further advance his own Synergist skills. Hajime's treasure trove ring and prosthetic arm were originally Oscar's masterpieces. It was through Oscar that Hajime got to learn about Ehit's true nature, and Hajime was able to gain insight towards the evil god's schemes due to Oscar's warning about the Liberators past defeat.

Meiru Melusine
Hajime also deeply respect Meiru for her wisdom and philosophy of independence in relying on one's own efforts and abilities to realized their wishes instead of relying on others and giving into the temptation of the evil god Ehit which Hajime also agreed from his own experience in conquering the dangers of the Great Orcus Dungeon without relying on others. Meiru's labyrinth also gave Hajime greater insight and precaution against Ehit as Hajime correctly predicted that Ehit had sent his Apostle Noint to abduct Aiko as well as assisting Eri and Hiyama in betraying their classmates and Fried's invasion of the Heiligh Kingdom. Hajime would also later make use of Meiru's philosophy to criticize Kouki and his other classmates about their idealism and naivety as their careless over-reliance on others and also Ehit's blessings and protection as his so called "chosen heroes" was what gave the treacherous Eri and Hiyama the advantage of using their enhanced abilities from Ehit's blessing to massacre and zombify Meld and the other knights into undead soldiers that nearly killed them in the former's death trap without even realizing it. Especially Kouki who stubbornly clung onto his glory and pride as Ehit's chosen hero even after the evil god's true nature was exposed due to his delusional hero complex, even giving into the temptation of his misguided self righteousness under Ehit's influence in the Frost Caverns of Schnee Labyrinth's doppleganger trial, failing not only his second attempt for Ancient Magic, and would have also nearly lost his own life by antagonizing Hajime by giving into Ehit's temptation as the members of the Holy Church did.

Koutaro Fukube
Koutaro has been in contact with Hajime for over a year as a member of the "Returnee Response Division", which is impressive by most standards since his predecessors could not even handle his job for three months. He is extremely scared of Hajime and always takes stomach medication at even the slightest gesture that is made by the demon king. Hajime feels bad that he has inadvertently caused Koutaro to feel so much stress, but views him as a highly competent public servant.

Roze Phiris Avenst
Roze is the queen of another world. She is amazed at Hajime's powers and initially mistakes him to be the "Dragon Knight" that she hears from stories of her childhood. After getting to know Hajime and seeing how he mercilessly treats his enemies, Roze now views him as a demon god, but still holds him in high regard. It is implied that she has romantic feelings towards Hajime.
