Hajime Nagumo

"I will protect you, Yue, and you will protect me. We are the strongest. We will mow all down, and we will cross worlds."

- Hajime to Yue

Hajime Nagumo (ハジメ) is the main protagonist of the novel series Arifureta Shokugyou de Sekai Saikyou.

Being called "incompetent" and later betrayed by one of his classmates, Hajime falls into the abyss where his journey to become the strongest begins.

Appearance
Hajime at the beginning of the story is said to have black hair and also has a slim body. He also had a kind face and attitude. But after falling into the abyss and eating the wolf-like monster, his body begun dying. When he drunk the sacred water, it made his body heal, destroying the bones and muscles, then healing over and over again until he got a very buff body called "overcompensation". Due to the stress of breaking and healing, his hair turned white, a condition called. His eyes also turned red and his body gained tattoo-like red veins, which is the sign of him becoming a demonic monster similar to the monster's he ate which allowed free use of magic without chants.

In the after-story his appearance has reverted back to before he and his classmates were summoned to Tortus.

Personality
He was originally an weak and average person with a timid and tolerant personality, but with an extremely kind and gentle heart. While a bit of a "Herbivore", he had a special type of bravery and strength of heart that would allow him sacrifice his own dignity and well being to protect child from harm even though he was against great odds. Kaori had noted that it would be easy to be a hero to fight against evil if one were already strong, but it takes true strength to go against evil if one knows that they are weak. This strength of heart is evidenced by his ability to keep calm when his class faced perilous dangers by a Behemoth, while Kouki had momentarily stood paralyzed by fear until snapped out of it by Hajime. He had a Motto of "Hobbies First" and would put his hobbies over everything else despite ridicule by his peers.

After the betrayal of a classmate and falling in into an abyss, he began his descent to madness. The fear of dying and the pain of losing his arm coupled with days of starvation pushed him over the edge. His iron forged will to survive had made him become extremely ruthless and capable of killing any person who wants to cause him misfortune or get in his way. He would also smile in front of danger which made Shia call him a new species of monster called "Predator". He may be merciless, but he deeply cares for his comrades which is the last and only fragment of his lost kindness. As the series progresses, Hajime eventually does prove himself willing to help the helpless (particularly if his companions coax him into it), though he continues to demonstrate a cold demeanor about the whole thing. His methods, however, are usually pragmatic (frequently to the point of brutality), and he is stubbornly resistant to guilt trips and appeals to his moral compass (as Kouki Amanogawa repeatedly encounters, and refuses to acknowledge).

During the Shunee Great Labyrinth, its revealed that he has some doubts of whether or not he can live in Japan due to how strong he became and was scared of being referred to as a monster. Although unlike others that would be distracted by the labyrinth's trials that induce doubt, Hajime learned to power through it and just ignore it.

Background
His father was a game creator and his mother was a shoujo mangaka. His original plans while in high school was to eventually get a part time job at his father’s company or mother’s workplace.

And all his Otaku hobbies were perfect for practicing his skills for his future plans and occupation.

In Middle School, Hajime had witnessed a scared mother and child apologizing to a punk for accidentally spilling something on the punk's clothes. An ordinary passerby would not have gotten involved, but he moved his body unconsciously when he saw the punk start to lay his hands on the child. Knowing that he was no match for the bully but still wanting to protect the child, he knelt down to beg forgiveness for the child even at the sacrifice of his own dignity. Kaori once witnessed this bravery and the strength of his heart that allowed him to stand against evil while a weak person and began approaching him everyday once she found him in high school.

Plot
At the beginning of the story, Hajime was a complete otaku in his class who always and always comes to class with a sleepy expression. He was always bullied and was glared by both of his male and female classmates for being close to their idol-like classmate, Kaori.

After wishing for his annoying classmates to be summoned to another world, the next thing he saw was that they were on top of a pillar-like structure in another world. Then, they become saviors called by the "GOD" on Tortus, Ehito, thus becoming one of the heroes.

However, he had the job "Synergist" which was not a cheat-like job with all his stats starting with 10. All of his classmates had cheat-like jobs and stats reaching the hundreds just by being level one. He was thus also bullied for being weak. After that, Kaori visited his room, telling him not to go to Orcus Dungeon, because she had a dream that someone is gonna take him away and Kaori can't just sleep with that thought. But Hajime comforted her that even if he will go with them, he will not be in any danger because Kaori is there to protect him which made Kaori happily nod in agreement.

After that day, they went to Orcus Dungeon to level up. They were fine until they reached the 20th floor when Hiyama touched a huge shiny ore in an attempt to obtain it for Kaori. It was a trap and everybody present was teleported to a lower floor in the dungeon. There, they saw a lizard-like monster called "Behemoth" which was the monster that was not defeated even with the legendary adventurer who reached the 65th floor. Hajime helped a girl surrounded by monsters and told them to keep calm or they are gonna die. Then, he got mad at Kouki who was full of justice and wouldn't leave behind Meld, saying someone should lead the panicking classmates. Hajime told Meld to help him after his classmates where it is safe while he was preventing the Behemoth from moving. After that, their party was casting magic to kill the Behemoth, but one classmate betrayed Hajime and hit him with a "Fireball" which caused him to fall off the cliff.

He wakes up to see a giant bear monster and tries to run away, but his left arm is bit off by the demon. Falling into despair, Hajime transmutes a hole to escape pleaing for his life. He thinks back to how it all started for him and becomes determined to return home and will kill anything and anyone who gets in his way. He stops the bleeding in his severed arm and confronts a wolf monster as he sadistically stabs it to death. He them retores his vitality and mana and eats the demon to fil up his stomach. After finish eating, he starts feeling agony until he realizes that not ony did his hair turned white but he also gained new power. After gaining some lightning abilities, he transmutes a revolver and calls it Donner. He then traverses the abyss killing and eating monster until he confronts the same monster that ate his arm. After getting injured again by it, he uses a green glowstone as a flashbang and shoots the monster's left arm off completely disintegrating it. He then finishes it off by shooting it in the head and then consumes it.

Three days after killing the bear, Hajime continues traversing the abyss gaining raw material until he confronts 2 cyclopses but kills them instantly. He then comes across a room with a little girl sealed inside some kind of magic box. She then explains that she was betrayed. She then explains that she's a vampire and was the strongest of her clan until her people betrayed her, so she begs Hajime to help her escape. Hajime obliges and breaks the sealed box. Hajime asks for her name, but she says that she doesn't have one and asks Hajime to name her. He names name Yue. As they are about to leave the room, a monster pops up in an attempt to kill them. They have a hard time killing it, so Yue tells Hajime to trust her as she bites his neck and drinks his blood and uses one of her strongest attacks called Azure Blaze. Hajime finishes it off by shooting a hole in it and sticking what looks like a grenade inside of it causing it to explode. After a month of exploring, Hajime and Yue open up to each other on how they both fell down the labyrnith into the abyss, and Yue decides to tag along with Hajime on his journey back home.

They fight off monsters in a forest until Yue is held captive by a plant monster. Yue tells Hajime to kill it and don't worry about her, and Hajime shoots blowing the plant monster's head off. When it seemed like they made to the end of the abyss, they're immediately cut off by a hydra-like monster. As they fight it off, the monster cast some kind of mind spell on Yue causing her to freak out until Hajime breaks her out of her hallucinatin by kissing her injecting a potion inside of her. After saving Yue, Hajime tells her to distract the monster so that he powers up his secret weapon which is an anti-matter rifle he calls Schlagen. As Yue attacks with another one of her abilities called Crimson Javelin, Hajime then fires a shot at the monster blowing off multiple heads at once. When it seemed like they were finished, the hydra regenerates and blasts an attack at Hajime mortally wounding him and blinding his right eye. He falls unconscious while Yue desperately fights off the hydra with his Donner but gets mortally wounded as well. Hajime regains conscious and steps behind Yue letting her know that they're gonna end this fight. Hajime distracts the hydra in its true form while Yue charges up her Azure Blaze. The hydra constantly blasts attacks at them, but Hajime dodges them all and transmutes the ceiling above the hydra making it fall on it. Yue then fires her Azure Blaze greatly wounding the hydra, and Hajime finished it off by shooting it in the head with his Donner.

Two months after clearing the labyrinth and learning creation magic, Hajime makes himself a prosthetic arm and makes Yue a necklace with a gemstone that contains reserved mana inside. Afterwards, they finally leave the labyrinth for good. After some walking, they find a hidden door leading to outside. They make haste through the Raisen Grand Canyon until they come across a bunny girl being chased by a two-headed dinosaur-like monster. Annoyed by it, Hajime steps in and kills the monster saving the girl. The girl then reveals herself to be a demi-human and that her family, the Haulia, lived the depths of the forest which was demi-human territory. Unfortunately, because of her abilities she and her family were exiled. The reason why was because originally, demi-humans had no talent for magic, but Shia did, and she had the ability to manipulate it. She has what's called the Inherent Spell Prophecy, the ability to see the future before it happens. She fears that if she's captured, she will be executed. During their time fleeing into the forest, her family was attacked by imperial soldiers and because her family were non-combative, half of her family was captured. Now she begs Hajime and Yue for help, but Hajime immediately refuses. Shia desperately begs and asks why. Hajime explains by asking what he gets out of helping a demi-human that has no home yet she has the ability to predict the future. Shia then admits that the future will change with hard work and that some futures won't change if you do nothing, so she's determined to believe that her vision of Hajime and Yue was meant to be and that she won't give up on them. Yue tells Hajime that they should go with her since they have no means of guidance through the forest and that they won't be defeated so easily. Hesitant on the matter, Hajime agrees to take her along. The demi-human then introduces herself as Shia Haulia.

 * Gatling Pile Bunker - Different from the pile bunker until now, the loaded pile bunker was two sizes smaller. But, its might didn't decrease for even a bit, in a second twenty electromagnetically accelerated shots spiraled forward and the huge and super heavy black pike pulverized the target.

It moves by the same principle as the Unmanned Reconnaissance Planes and their type specialized in attacking. Inside were loaded with gun and rifle bullet, they were operated using the bracelet where seven induction stones were installed. Moreover, the surface was covered with minerals which endowed with “Vajra” using Creation magic, so they could become strong shields as they reacted on the magic power from induction stone. When becoming a shield it becomes a huge flower-like cross. It can also self destruct when the enemy is distracted by its shooting power and acts like a surprise attack. When four points were united a boxed-type barrier would be formed. It’s not just a simple barrier though, it’s the type that shuts out space itself through Spatial Magic.
 * Custom made torpedoes  - Made by Hajime which would be used in Elisen, «Meljeenae’s Seabed Ruin» (One of the seven great dungeons and is also located underwater).Hajime thoroughly painted them so they looked like smiling mischievous sharks.

It has a remote control with an induction stone.
 * Magic powered Bola - It looks like two balls attached by a string to catch opponents. It also makes the opponent float at the air in a fixed space.
 * Hyperion - The weapon Hajime used to fire the "Light of Condemnation". A pillar of light with the length of 50 meters and erases whatever it touches. It can be described as a laser beam satellite powered by Magic and is a sunlight convergence laser. It is an enormous air-frame lens which converged sunlight, it can also charge itself while inside of the “Treasure Warehouse” which had heat capacity installed in it. Enormous heat which critically overflowed from the “Treasure Warehouse” would be discharged through the launching entrance where gravity magic was added in to make it discharge towards the ground. Its biggest feature was the fact that it could still converge the sunlight even while it was nighttime. Its secret was due to Oscar Orcus’s false sun which lit up his rooms. That thing’s sunlight was created through Reproduction magic along with Space magic. It has a remote control with an induction stone.
 * Burst Hyperion - improved version of Hyperion that had been explosively evolved in heat quantity, convergence rate, lasting time, and so on couldn't be compared with the previous Hyperion Using the 'distant viewing stone' loaded on Burst Hyperion, Hajime could even see the figure of people that are far away. Burst Hyperion had total length of around five meters
 * Mirror Bits  - The bits with isosceles triangle shape and size around thirty centimeters had crimson gem installed on their surface. the role of the mirror bits were to reflect the sunlight convergence laser of Burst Hyperion which was their mother machine. With that, they can exterminated the enemy from every direction. the bits had the word 'mirror' attached to their name, but they weren't reflecting the laser using mirror but by making use of space distortion. Using that it was also possible to bend the laser in sharp angles. In a glance, it looked nothing more than a reflection,
 * Ferner - An airship built by Hajime, mainly made out of gravity stones and induction stones, along with other various functions built in. Ferner is 120 meters in length and in the shape of a devil fish, inside of it contained halls that led to the bridge towards the front and living quarters at the center, furthermore, there was also a kitchen and room to take baths.
 * Mic Ferner - In a manner of speaking this artifact was a skyboard. With a shape like a surfing board, it reduced things like air resistance with space magic and flew in the sky using gravity magic. The control was of course using sympathy stone. With the air resistance equal to nothing, the burden to the user's body was extremely small, so it could easily give out a speed of five hundred kilometers per hour. It was an improvised item so there was a flaw that the magic power consumption was large.
 * Gate Key - A key made by Hajime to activate the gate hall.
 * Gate Hall - A lock made by Hajime. When thrusting out the gate key into space this process was “Opening the Lock”, the gate then connects the space to the place in the gate hall that is set up beforehand in order to be transferred to it. Of course, it was created with a combination of space magic and creation magic.
 * Spider-type Golem Scout - A metal-spider made by Hajime powered by magic it can make hole's in a hole and can cover it up. It can be used for assassinations. can go anywhere through remote control with “Transmuting” and “Thread”, the images are sent to the “Crystal Display” through the “Distance Transmitting Stone”, and it can sense magic traps just like the magic eye. It also has paralysis and sleeping poison on its feet, even poison which makes it so that the little sonny doesn’t get up.
 * Improved Telepathy Stone - It's a telepathy device created by Hajime and later improved into this version. The principle was this. Ore’s with the property of “High-Speed Magic Recovery” was created through Creation Magic and added into the magical power tanks which caused them to auto regenerate, it always added fuel back into it as “Magic Emission” was being emitted. And the magic formation needed to activate it was a kind of sliding switch which was placed on it to allow it to smoothly activate on and off. Furthermore, there was a function which responded to the blood and status plate, meaning only the blood of the user would be accepted.
 * Presence Severing Stone - A device that conceal one's presence. Probably given the property of "Hide Presence" and "Sign Interception" through Creation Magic.
 * Fairglass - A goggle-type artifact that can detect magic traps. It was given to the Haulia Tribe.
 * Grenzen - Magic power cannon, a pure magic power bombardment artifact. From his experience in Merujiine Undersea Ruins, there was also some situation where a pure magic power attack would be useful, so Hajime learned and created this. Although until now, there was no chance to use it, so it was something that was shelved. The derivative of ‘Magic Power Manipulation’ that was ‘Magic Power Emission’,‘Magic Power Compression’, ‘Remote Control’, also ‘High-Speed Magic Power Recovery’ and its derivative ‘Magic Source Absorption’, all those skills were used as a base and included into the magic power cannon. It focused not just Hajime’s magic power but also the magic power of the outside world, combined with gravity magic so it could compress that magic power. The more the compressed magic power was then the more the amount of magic power of the target would be blown away.
 * Compass of Guidance - Uses spirit magic to surmise what the user was wishing for, then using space magic it ignored the spatial gap and distance and searched the target, it seemed that the compass used sublimation magic to supplement the information of the target. All of those functions couldn’t be accomplished using the age of magic without concept magic.
 * Crystal Key - It was a characteristic artifact, made of the God Crystal and other rare materials, that looked antique with its crystal form that had a complicated and delicate pattern and twelve exact sides―the ‘Crystal Key’. It is like the Gate Key, but it can open a door to any desired place, even if it is in another world.
 * Degraded Version Crystal Key - Based on his experience when creating the real crystal key, Hajime produced with his all this short sword that possessed the effect to interfere with space. It didn't have the power to open a gate toward the Holy Precincts, but if it was just the power to lock pick a locked door then this item could do it.
 * Rose Helios - They were special treasure warehouses that stored sunlight which was focused until the limit. It was different with the treasure warehouse that was built internally to shot lasers, so to speak it was a large scale heat bomb that made use of the suns energy by self-destructing to release all the stored energy at once. The heat that was continuously converged was liberated and caused a large explosion like sun flare. ( it is installed in Hyperion to increase it firepower )
 * Solar bombs - It is filled with highly compressed sunlight which was focused until the limit it. The heat that was continuously converged was liberated and caused a large explosion like sun flare.it could easily obliterated space up-to 10 kilometer (it is was used by Hajime to destroy 9 lower level of hell )
 * Orestes - The chakram up to now could only create a gate at the small inside of the chakram, but this new type chakram ‘Orestes’ that had improvement applied in it could separate and with the built-in wire inside, a gate that could be freely changed in size would be made. Depending on the situation, it could also be used as a guillotine by making something passed halfway into the gate and then decreasing the size.
 * Cheatmate - Minerals that didn’t have an adverse effect to human body like calcium and the like were enchanted with metamorphosis magic and sublimation magic, it was then turned into powder and then transmuted and became a solid food with a particular effect. With this food the body was temporarily transformed into an optimum condition in metamorphosis, next, strengthening effect that was nearly like ‘Limit Break’ was also applied on the eater so that they could endure even heavy burden.
 * Holy Water - It is what Hajime called the potion dropping from the God's Crystal. It can recover any wounds and status effects in fast a succession rate.It is also limited because of the fact that the God's Crystal stopped dropping "Potion".
 * God Crystal - A very rare item found by Hajime when he fell from the abyss while being chased by the demon bear. It drops Holy Water. After completing the Orcus Labyrinth it lost it power due to the power it accumulated running dry. Though Hajime tried to empower it, it proved impossible due to it having to collect power gradually over many years. Hajime would later use the God Crystal to create various jewelry for Yue that acted as spare magic storage tanks.Due it high durability and abilities to store magic Hajime also use it to created Concept magic artifact. Since all remaining god crystal was Ehito and in order to return japan Hajime started created god crystal by himself
 * Bel Agartha - A satellite like artifact that is capable of healing any target to perfect health and has even been shown to restore those who had died recently.
 * Magic Crystal series - It was god crystal after losing it power to create holy water Hajime used it created jewelry for Yue that acted as spare magic storage tanks since it has abilities to store high capacity of magic power
 * Aidion - It large shield with function of creating a large dome using the metal plates that were sliding from the inside of the large shield in great speed to formed a dome that covered it user. to protect from the attack coming from all direction it also installed with green light stone inside it so it wouldn't be dark inside even if a part of shield get destroyed it can be regenerated immediately with the help 'Restoration Stone' that was enchanted with regeneration magic. Aidion was similar with 'Sky Severance' where it was a composite shield made of several layers of adamantium inserted with restoration stone, furthermore, Hajime's 'Vajra' was also reinforcing it. In other words, even with one layer destroyed, if the second, third, and fourth layer could buy time even for a second then the restoration stone could display its effect Therefore, even with highest grade magic the opponent couldn't hope to penetrate it
 * Hour Crystal - With the help Kaori regeneration magic 'Temple Rend' (it was a magic to stretch the time) enchanting the technique that Kaori used into the crystal pillar using creation magic. it is possible to interfere with time itself. to put it simply it is able to Slowing down the flow of time of a certain range

Combat abilities
This The metal dust that had invaded into the body penetrated until inside the blood vessel, shredding the target from inside. If Hajime wanted, he could also use the crow type artifact "Ornis" as relay point to adjust the dust using "Convergence Transmutation", making the metal dust inside the body reacted and gave only intense pain without killing the target. By the way, the crimson light was optional! The metal dust was clad with crimson light, becoming heavy fog that covered the world. The living organism inside that territory would have the inside of their body within the grasp of the demon king, at the same time their right to live or die was also wrestled away from them. "Gag Bullet" even though the impact was terrific, by using regeneration magic the target would be able to stand up again in three seconds as though nothing had happened, it was a bullet to make gag situation in real life ( The classmate's naming => You cannot escape from the demon king-sama! ) It was a simple harassment done by simply making several hundreds Cross Velts laying out super wide range space isolation type barrier. Currently, the space in a radius of three kilometer around Hajime as well as until the height of three kilometer was completely isolated. it was first used when the illegal agents of a certain country in earth tried to make a move against the returnees. At that time, Shinji and Yoshiki who carelessly entered the range kept yelling? Let us outtt~, let us out from hereee~? while hitting on the invisible wall. With the cooperation of Tio who was the best in using metamorphosis magic, Hajime succeeded in developing the Grim Reaper - Bio Hazard version that he was completely fixated upon. And he released them inside the barrier at that time, so the two's reaction was understandable. The Tyrant was especially popular. To the degree that several people completely lost their SAN value It was a devilish harassment that would make a certain god of death from hell to say 「That’s wrong」 with serious face ――Now, everyone, are you all finished with your preparations? ――It’s starting you know? Peek, a demon king!

 * Weaver Stance - Hajime's right arm thrust straight forward and left arm’s elbow slightly bent. His feet, one positioned forward and one backwards. It was the shooting posture, the pose to accurately fire Donner.
 * 108 Harassment Demon king-style : it is one of the harassment style developed by Hajime after the battle with the Ehito in order to deal with the problem. there are total 108 harassment style but only few them, are reveled so far

The barrier vanished, and the Presence Isolation was dispelled.What appeared was a bursting crimson magic power with the demon king-sama grinning widely at the center.

 * Concept Magic - allows you to understand the principles of all things and create, manifest a concept.
 * Creation Magic - if it was expressed more accurately then it was a ‘magic that interferes at inorganic material’, a magic that was the opposite of metamorphosis magic. And so theoretically this magic should be able to interfere with things like water or salt too, not just mineral.
 * Gravity Magic - Gravity magic was something that should be expressed as ‘magic that interfere with the energy of star’, not only gravity, theoretically, it could also interfere with things like earth vein or terrestrial heat, bedrock or magma, it wasn’t impossible to use this magic to purposefully generate earthquake or volcano eruption.

Shia’s characteristic magic of ‘Future Viewing’ was likely originated from this magic.
 * Spirit Magic - To define spirit magic the expression of ‘magic that interfere with negative material possessed by living thing’ showed its true nature the most. To say it specifically, this magic could also interfere with things like energy inside the body that was magic power, heat, electricity, then thought, consciousness, memory. Although this magic was designated as ‘soul/spirit’, what Yue and others could exercise with this magic was interference at thought body more accurately. And then if someone could handle this magic perfectly, the caster could personally create consciousness and the like, they could conjure it too. To put another way, it was possible to create artificial intelligence using magic.
 * Sublimation Magic - Expressing sublimation magic as ‘magic that interfere with the information of existing thing’ was more accurate definition. Its function that evolved an ability by a level was, for example, interfering a body information that said level 1 and raised it up to level 2. If the user reached the root, it was possible to browse and interfere with the information of all existing object.
 * Metamorphosis Magic - It’s a magic that interferes at organic material. You can also think of it as magic that interferes at material that originated from living thing. In other words, if you feel like it, not just an animal but something like a plant, and also things that are made from that――for example food or paper, this magic can also interfere with that kind of thing. Of course, it can also interfere at the human. The magic stone is nothing more than a byproduct.
 * Deny All Existences - Concept magic that, through sublimation magic, overwrites other's information from "Exist" to "Non-Exist" and fill it into thin thread-like chains created with transmutation. Everything that touched by the chain will be erased and feel a great agony and pain even if the target should not feel any pain.

Relationships
Yue - Yue became Hajime's most important person after he fell into the Abyss. The two quickly grew close due to their similar backgrounds and similar 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 the other's safety. Even though Hajime is surrounded by women who want to be his lovers and Yue herself wants him to be intimate with Shia, he has never wavered. 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. 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 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.

Shia Haulia - During their first meeting Hajime's impression of Shia was bad due to her excessive clingy attitude. Hajime wouldn't allow Shia 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 Shia as part of their family but to Shia's and shockingly Yue's great disappointment Hajime could not see Shia in a romantic light. However. that began to change when Hajime realized that Shia is just as important and irreplaceable to him as Yue and has begun to show his previously hidden feelings for her. Without realizing it the two have created their own "pink world" while they are alone.

Tio Clarce - After defeating and arguably "tainting" her, Hajime has been followed by the masochistic and incredibly perverted Tio 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. During their fight against Freed Baghaur, 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 Myuu's safety while he and the others went into a dungeon. Hajime later confesses that he loves her when her father and the rest of the dragon race decide to help him wage war on Ehito.

Myuu - Hajime and Shia saved her from a sewage system after she escaped from slavers. Myuu immediately bonded with them and began called 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 travelled 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 Myuu to her mother, Lemia, 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.

Amanogawa Kouki - Hajime has a neutral standing about 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.

Yaegashi Shizuku - Hajime cannot handle Shizuku for she knows his secrets such as chuunibyuu stuff. Shizuku later admits to him that she has feelings for him.

Quotes

 * (To Ilwa Chang): "A piece of paper can be a good shield if you use it right. My job’s Synergist, you know? My duty is to make sure anything that can be useful is made useful. Don’t worry, I’ll make good use of your support."
 * (To Daisuke Hiyama): "Don’t pin the blame on other people. You’re the one who decided to stoop to this level. Both here and in Japan, you’ve always been the loser. You didn’t lose to other people. You’ve lost to yourself. You never once tried to take responsibility for anything. All you ever did was sit on the sidelines and insult everyone else, when the real loser was always you."
 * (To Kouki Amanogawa): "If I have power, I should use it for justice? It’s because you think like that that you always end up messing up when it really matters. Personally, I think power should be wielded with a clear intent. You don’t do something because you have the power to. It’s because you want to do something that you obtain the power necessary to achieve it. If you really think you’re obligated to do things just because you have the strength to, then for you, strength is nothing more than a curse. You lack resolve, Amanogawa. Anyway, I’m not going to argue with you about the path I’ve chosen. If you keep pissing me off I’ll send you flying out of here like I did with Hiyama."
