Hajime Nagumo/Relationships

Yue
The deposed vampire princess, Aletia became Hajime's most important person after he fell into the Abyss. At first, when Hajime discovered her 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In the Haltina Labyrinth, Hajime was instantly able to tell that Yue had been replaced by a slime that was impersonating her and was instantly able to identify Yue even though she was forcibly transformed into a goblin.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 only her until Yue finally convinced him to accept Shea as his lover as well. His reasoning being that 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 wanted to stay with Hajime and will always be only with him but not one else. 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 is 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 Labyrinth and 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, as she and Kaori among his wives are the closest to him.

Kaori Shirasaki
Hajime has always seen Kaori as a friend even though her attention brought him nothing but trouble. When Hajime began his travels he had decided to discard his former classmates after his transformation but the moment he heard Kaori was in trouble he went into a dungeon to save her to repay her kindness. In the end, Kaori decided to travel with him determined to win his affection despite his drastically different personality.

While Hajime said he wouldn't respond to her feelings because he was in a relationship with Yue, she refused to give up on winning him over. Hajime has proven that he does see Kaori as someone important in his life, becoming incredibly furious and brutal towards anyone who harmed her to the point where he will make them suffer horribly before killing them. In the harsh journey, Hajime offered Kaori to return to Shizuku when she displayed sadness at her own weakness compared to the other members of Hajime's party but she refused and always remained by his side no matter how ruthless Hajime acted or how harsh the journey might become. For Hajime Kaori is important to him when he saved her from the influence of an evil spirit. Kaori always believing everything when Hajime told her even she readily agreed of Ehit's true nature as an evil god who used them as pawns to his "chessboard of life". Kaori will always remained in Hajime's side no matter what happens or those who are foolish enough to try to take her from him when simply refused to Kouki's demands of returning to the so-called "Hero Party" as a pawn to Ehit's "chessboard of life and death" even if it means for Kaori to be the so-called "heretic" by the Holy Church or Garland. After Kaori was killed by Hiyama and Eri, he became absolutely furious and unleashed his true power by destroying every single one of Eri's undead troops and slaughtered Hiyama, while at the same time became determined to revive her using spirit magic, putting it as his top priority at the time as he promised her to put her soul into a strong body due to her not wanted to stay weak anymore so that she would win Hajime's affection.

After the Haltina Labyrinth, due to realizing how much his comrades (the harem) meant to him after his feelings about them were magically reversed due to magic, he was forced to publicly admit that even Kaori had a chance to make him fall for her. Eventually, Hajime does develop feelings and love for Kaori after she comforted him at his loss for Yue, and accepts her as one of his lovers/wives.

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 it forced Hajime to delay his plans to conquer the labyrinth.

During the ordeal, he slowly started to see Shea in a different light. 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. After they marry, she and Yue become his two most favorite wives.

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 and disgusts everyone else.

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 and killing the Holy Church members that were interfering in his fight thus helping her achieve her revenge. 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, even going so far as to trust her with Myu's safety while he and the others went into a dungeon. He also has great respect for her level-headedness 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. However even when Tio was transformed into Super Tio, the graceful princess of dragonmen who wasn't perverted, Hajime himself said that he preferred the perverted Tio and reverted her back to her perverted self by insulting her.

Hajime later confesses that he loves her when her grandfather and the rest of the dragon race decide to help him 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 has 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 willing to help her out on many occasions, including giving her one of his masterpieces, a new enchanted black 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 reviving 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 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 (while she is sleeping) to find the others.

After Hajime stopped a corrupted Kouki's rampage without killing him, with gratitude and love, Shizuku affectionately kissed Hajime, confessing to Hajime 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 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 destroyed the Holy Church (together with Tio) 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 survived and Kaori decided to travel with him, she tried to dissuade her father, the nobles, and the Church from declaring Hajime a heretic so that both he and Kaori could have a place to return to. After her father and nobles started behaving oddly, she decided to search for Kaori and Hajime to get help as they were the only people left she could trust. Although she knew 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, where Hajime defeated Noint and 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 quickly grew angry and exasperated with Hajime due to him causing her trouble during her diplomatic trip. After Hajime 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 as 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 co. 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 Earth.

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 Orcus Labyrinth and lost his left arm, 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 Orcus Dungeon, doing everything in his abilities to become strong enough to survive and returned 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 the Kingdom of Heiligh. 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 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 respectfuly 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 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 learnt of Ehit's true nature in the Orcus Dungeon, Hajime had come under Ehit's notice as Hajime had refused to obey the god's creed as his so called chosen hero by rejoining his classmates and aid the Holy Church in the war against Demons. Hajime, having foreseen Ehit's schemes through the Liberators past defeat, 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 considers Hajime "Irregular" and wishes to remove him from the 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 no matter how much he defy Ehit, 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 of managing to revealed the truth, Hajime has successfully made the human worshipers who were once devoted to Ehit of turning against him which caused fears to the false god after learned they were being used as playthings.

When Tio revealed to Hajime of Ehit's 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 Labyrinths, Ehit decided to wait until Yue managed to acquire all of the Ancient Magic to possess her as he sent 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 to the evil god when he realized that Hajime was aiming to kill him not to save Tortus from his manipulation like the Liberators and Kouki wanted to, but simply because Ehit was just another enemy for the latter to kill for standing in his way and to avenge Tio's people.

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 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 could make Hajime surrender by using his classmates as hostages. 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 for his ignorance as well threatening to kill him and destroy the rest of his army unless he retreated. Though furious, Freid retreated as he 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.

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 causing Kaori Shirasaki to fall in love with him. Daisuke secretly betrayed his classmates by his attempted murder on Hajime.

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 he will murder anyone who gets in his way even if they were once classmates, Daisuke is shown in fear that he is now no match for Hajime. When Kaori joined Hajime's party, Hiyama shown in greater fears when witnessed Hajime has easily defeated Kouki in an unarmed duel.

When Hajime and his party prepare to leave, Daisuke feigning his apologizes to tries to "convince" Hajime to forget what he have done to him and his mistreatment in the past to rejoin the Hero Party (just so he could get close to Kaori). But for Hajime, however 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 Daisuke's betrayal after he left Hajime to die in the bottom depths of the Labyrinth in front of him and his gang. He even warned them to stay out of his way if they wish to live causing them to become terrified of Hajime and give up in their pursuit on Hajime and in worse case made Daisuke go insane as he realized that his life was at the palm of Hajime's hands and he will never make Kaori his girlfriend.

After Daisuke revealed his betrayal and temporarily murdered Kaori, the raged-filled Hajime fought Daisuke and overpowered him with ease. While Hajime gripped Hiyama's neck, he tormented and beat up his former bully for killing Kaori as he called Daisuke a weak selfish loser as the reason for Kaori to never to fall in love to the likes of Hiyama and he brought about his own downfall after Hiyama blamed Hajime for getting attractions from Kaori. When Daisuke insolently bragged his final words of how he persistently will kill Hajime and make Kaori his girlfriend one day, Hajime has brutalized Hiyama ever further and told his former tormentor that he will not get his chance of trying as he won't be able to survive as Hajime put the nearly broken boned and organ damaged Daisuke out of his misery by kicking him to the courtyard filled with a horde of demonic beasts and watched pitilessly as the demons devouring Hiyama as he is screaming for agony and terror. Hajime eventually walked away and abandoned Hiyama to his miserable death to confront Eri where 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 as a lesson to his classmates of what would happen if anyone dares to cross him and break his absolute warning by harming one of his companions (harems). 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 or harming one of his comrades (harem) ever again only for Hajime to accepted the two as annoying stooges. Hajime also scolded Kouki for his naively expecting his classmates to naturally help and protect his comrades just because they are classmates only to allow the traitorous idiot, Hiyama and the intelligent Eri to betray him without him ever noticing it. Nakano and Saitou shows proper respect to Hajime after they return to Earth but he usually gets annoyed with them as he considered them both as stooges. 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 as a selfish and despicable traitor after Hajime enlightened them on the truth behind his fall into the abyss. Thus none of them even bothered pretending to mourn for him and ceremoniously buried what was left of Hiyama's body after it was found. In the funeral, nobody holds any sympathy or respects for Hiyama after branded him as a traitor. Out of all his former classmates who held a grudge on Hiyama for his betrayal even in death, Kouki was the only one who condemned Hajime for murdering Daisuke despite his treachery though this was mostly due to his delusional justice which persisted even after the latter's betrayal.

In the After Story roughly 6-7 years after he murdered Hiyama, Hiyama's family try to get revenge on Hajime only for him to easily defeat them. They have also suffered an extreme breakdown after being told of Hiyama's betrayal in Tortus that lead to his murder by Hajime.

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 prolonged battle and later used her corpse as a vessel to revive Kaori after she was killed by Daisuke to both save her and to insult the evil god. 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, she become loyal to him and would rather wanted to be into her new body as she has no attachments to her old body.

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

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" in the wedding photo shoot as a warning if they challenged him again causing them to run away from their ambush of Shizuku wedding photo shoot with Hajime due to him completely humiliating them in publicity. After gotten humiliated by him, everyone were laughing at them even in 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, only for Hajime defeated them all with ease. For Hajime however, he isn't impressed by the students and got incredibly annoyed (along with Shizuku) because the students would attack him over and over again with their persistent stubbornness.

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 destroyed all of their hideouts to put an end to slave trades forever.

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 her boyfriend. Like Hiyama, Eri is also terrified of not only Hajime's survival but his monstrous strength and murderous instinct when he killed Cattleya. After capturing Remia and Myu, Eri believe of using the Dagon mother and daughter as good hostages against Hajime. Upon his arrival during the demon invasion, Hajime prevented Eri's "Blind Soul" from turning Kaori into Daisuke Hiyama's undead sex 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 slave, though is only made Hajime expressed an even greater rage. Eri sent her undead soldiers to attack Hajime only for them to be easily destroyed by him. Hajime's monstrous wrath caused Eri to become more terrified after he destroying her soldiers. She tried to attack him with daggers only for the latter easily overpowering her and tormented her worse than what her mother and stepfather did. She fear the worse when Hajime was prepared to coldly kill her for her betrayal while disregarding whatever reasons and motives she had for her betrayal but was saved by Hiyama when he attacked Hajime. After Hiyama and the undead soldiers' deaths, she got away with Freid when he retreated. When Eri captured Yue and presented her body to Ehit, Hajime has shown to be enraged as he will kill Eri for taking his lover away from him since the traitor dashed away her chance for redemption. Though he seems no longer need to when Eri died by committing suicide in an attempt to kill Suzu in the final battle.

Garland
Hajime and his companions (harem) are deemed to be the greatest threats and the most wanted "heretics" to Demons and their land after not only he and his party (harem) 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 and captured Remia and her daughter, Myu as hostages, Hajime wiped out 100,000 initial troops and threaten them to kill them more if they don't retreat which caused them to retreat.

Cattleya (deceased)
Hajime is Cattleya's murderer.

When Hajime arrived, he told Cattleya to leave or die. She chose 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 her lover will avenge her one day which Hajime doesn't care who his enemies would be either demon or god. Hajime then shot her at the head while disregarding Kouki's pleas causing most of his classmates to be terrified of him.

Alv (deceased)
Hajime is the killer of the so-called "god" of demon race.

When confronting him, Hajime trapped Alv into a small cage and tortured him to give him the location for Yue. When the severely injured Alv begged Hajime to spared 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.

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.

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

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 (harem) but was first insistent that he only loved Yue in a romantic way but that changed when Shea manged to get Hajime to acknowledge and accept her love for him too which lead him to accept Tio's 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 (including Kouki) who wish to seduce them, sometimes even threatening them and using violence to keep them away from his harem. He will never let anyone who is stupid enough to take his harem even through worthless fights and weak challenges such as when he defeated Kouki so easily twice. 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 clan and help them take down 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 was killed (even if temporarily), Hajime shows his wrath by murdering the one who killed his comrade (harem) as he murdered the traitorous idiot, Hiyama for temporarily murdered Kaori. Hajime willing to do anything to revive one of his harems 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 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 Earth even if it means leaving their own home in Tortus and people they care for. They often compete 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 when other men attempt to hit on or attempt to seduce them, frequently becoming annoyed when they approach. Kaori made promised with Hajime if she dies, revived her and place her into a stronger body.

In the After Story, Hajime married 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.

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.

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.

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 alive, and about his journey and how he 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 had 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 result.

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.

Meld Loggins (deceased)
The former Knight Commander of the Heiligh Kingdom that was entrusted with the responsible 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 respects and still still speaks highly him to this day. Hajime was willing to use one of his Ambrosia to save Meld's life when he came to rescue him and the hero party at the Orcus dungeon, admitting he didn't want him to die. Meld on his part was grateful that Hajime saved him and the others, happy he survived and regretful he (Meld) failed to save him before. Hajime becomes saddened to 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.

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 mission he assigned without hesitations.

Kouki Amanogawa
Hajime has a neutral standing about his self-proclaimed rival Kouki and ignores the fact that Kouki envies him. He only has a 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 Kouki's bad habit of only believing what fits his worldview and his annoying sense of justice even after the latter had failed so many times because of it. He even preferred not to explain to Kouki about Ehit's true nature because he knows Kouki will never want to believe him given Kouki's delusional idealism and pride as Ehit's so called chosen hero of Tortus. While Kouki one-sidely sees Hajime as rival, Hajime however sees Kouki as an immature, stubborn and spoiled brat with grand words lost in his delusions. Thus, Hajime decided not to bother warning Kouki and the rest of the Hero Party about Ehit's true nature as an evil god and his schemes in summoning them to Tortus as pawns for his mad death game as Hajime correctly guessed that Kouki will get mad at him instead for slandering Ehit whom Kouki had blindly trusted for being his chosen hero and the glory of all the hero worship he had received from Ehit's worshipers of the Holy Church and Heiligh Kingdom up until the demon invasion of the kingdom.

As a former member of the "Hero Party", who had learned of Ehit's true nature as well as having became powerful enough to survive on his own in Tortus, Hajime refuses to take orders from Kouki 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 thinks he have the right to enforced his misguided justice upon Hajime and his friends (harem). When Hajime's lovers are greatly annoyed and disgusted by Kouki's insolence, Kouki self-righteously challenged Hajime into an unarmed duel only to be defeated and humiliated by Hajime when he tossed him into a pitfall filled with non-lethal grenades to end such a pointless duel.

Hajime also viewed Kouki as a masochist hero and a pathetic emotional weakling who can never defeat him due to the latter's lack of resolve and continuous attempts to enforce his naive beliefs on him only for Kouki to end up losing to Hajime in both strength and willpower.

After Hajime murdered Hiyama along Aiko exposing Ehit's true evil nature and his schemes to his classmates, Kouki stubbornly attempted to blame Hajime for Fried's invasion and Eri's betrayal by not warning them earlier about Ehit. Hajime however 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. 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 scolded Kouki of his delusional heroism 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 regardless of their own personal wishes, Hajime then coldly refused to follow Kouki's wishes and demands as the reason why he went through countless hardships to attain power was simply to go home rather than becoming a hero for Tortus.

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 Liberators's Labyrinth and gain Age of God's Magic due to Suzu, Shizuku and Ryutarou's pleas but kept his warning that if Kouki continued to test his patience past his breaking point he will kill him just like he did with Hiyama.

Even though Hajime saved him and the rest of his classmates twice, 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. 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.

Due to Hajime's newly wildly apperance, Kouki became more jealously of Hajime's ability of getting a harem of more beautiful girls (including Kaori and Shizuku). While Kouki on the other hand, lost all of his popularity for girls completely after Hajime winning their hearts. Kouki furiously asked why Hajime is the only one gotten harems while he doesn't.

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 he'll kill him just like he killed  Hiyama.

During their trials in the Frost Caverns of Schnee, Kouki was corrupted by his doppelganger and 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 his both delusional pride and naive justice over everything else especially his own goals. But when Kouki saying Yue's name without honorifics, Hajime brutalized Kouki for the worst case due to Kouki has no rights to say 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 by separating from his doppelganger and killing it before punching the latter unconscious, thereby ending another pointless and hopeless fight.

Later in After Story, however, Kouki has trouble sorting out his feelings towards Hajime as due to his past actions and failures, Kouki cannot bring himself to be angry at Hajime but rather disappointed at himself for being so completely indecisive and not strong enough to realize his ideals. When the "Dark Being" 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 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 their friends 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 (summoned by Mother), Noint/Netemp, Jasper, and others like the upperworlders and underworlders.

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 once 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 friends.

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 Orcus dungeon, 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 seeing what happen to Hajime that caused most of them to become too scared to fight anymore.

However, Hajime survived the fall and decided to focus on his own goal instead of returning to them, thereby severing his ties to his classmates except for Kaori, Shizuku, and Yuka whom he only cared about. When Kousuke Endou reunited with him first and informed Hajime about Cattelya's ambush, he was willing to leave 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, he 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. 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 defiantly shot Freid and destroyed the latter's army of 100,000 since he literally couldn't care less if all of his classmates were to die by Freid's hands. Hajime transformation shocked all them to the point where they had difficulty recognizing him at first and became terrified of him as well especially for those who bullied him in the past. 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 both prior to and after their summoning to Tortus and thus ultimately didn't begrudge Hajime for not viewing them as comrades.

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 exception of Kouki (due to his delusional mindset). They became even more terrified of Hajime's wrath after witnessing how he brutally murdered Hiyama for the latter's betrayal and temporarily murdering Kaori, understanding what would happen to them if they dare to cross him like Daisuke did. With the sole exception of Kouki, when Aiko exposed Ehit's true nature and schemes to them which was what nearly led to their deaths by Eri's betrayal, all of them didn't dare to try blaming Hajime for not warning them about Ehit earlier. Besides their now traumatizing fear of Hajime, this is also partly because of the fact that they themselves did nothing to help him from Hiyama's bullying in the past, thus Hajime himself has no obligation to help them in return, especially regarding his harsh but correct criticism that it was ultimately their own careless optimism and naivety was what Eri and Hiyama had exploited to betray them without even noticing until it's too late. Also not to mention that Hajime had previously clarified rather coldly that he himself doesn't view most of them as friends or comrades in the slightest. While willing to kill his former classmates out of annoyance of Kouki, he gave them second chances to join him in conquering the last Great Labyrinths thanks to Suzu Taniguchi, Ryutarou Sakagami and Shizuku Yaegashi request but kept his warning that if they cross him or harm his harem for one last time, he won't be forgiving them and will kill them just like he did to Hiyama. After the demon invasion along with both Eri's defection and Hiyama's death, they've learned valuable lessons regarding their mistakes for not helping Hajime in the past by showing their remorse and gave proper respect to him in their resolves except for Kouki (due to his delusional mindset of his weak resolves). In the funeral when Hajime enlightened them of truth of his "fall", they don't condemned him unlike Kouki but rather held their terrible memories for their hatreds towards Hiyama and not having any actual sympathies for him after branded Hiyama as a traitor. When Hajime offered to enhance their weapons and armors with new abilities, his classmates rushed over to hand him their equipment to be enhanced but once failed to do so to Suzu's bracelets as they were destroyed until Hajime gives Suzu one of his masterpiece: a pair of twin iron fans as a gift to compensate.

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 the latter gave Hajime respect by considering the former as 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 but now stooges to him.

When Hajime returned after surviving the Great Orcus Labyrinth and seeing he had obtained monstrous strength, they became terrified of him. After Hajime killed Hiyama and Kondou, they redeemed themselves and kneel to apologized to Hajime as they swore they will never get in his way or harming his comrades (harem), including Kaori only for Hajime accepted them as stooges. After Ehit's death and returning to Japan, Saitou and Nakano started showing respect for Hajime, but he only to finds them as annoying stooges.

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.

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

Other Students from Different Classes
It is unknown how the other students from different classes in his school feels 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 more jealous of him as they attempted to attack Hajime but only for him to pulverise the other boys easily and caused them to be afraid of him..
