Hajime Nagumo

Hajime Nagumo (ハジメ) is the titular main protagonist and anti-hero of the "Arifureta Shokugyou de Sekai Saikyou" series.

He was originally a member of the Hero Party, where he was ostracized for receiving the commonplace "Synergist" job and his weak stats, until his presumed death in the Orcus Labyrinth, after which he discovered the truth about the world and made it his goal to return to Japan at all costs. He mutated into a monster hybrid when he devoured the meat of the monsters and is no longer considered to be a pureblooded human.

Appearance
Before his transformation, Hajime had black hair, brown eyes, and a slim body, along with a kind face. After falling into the abyss and eating a pair of twin-tailed wolf monster meat, his body began to wither away. He immediately drank the ambrosia found in the abyss to counter the poisonous effects of the monster meat. His body began to heal and grow stronger and becoming more muscular. Due to the stress of the revitalization, his hair turned white. His eyes also turned blood-red and his body gained tattoo-like red veins (Light Novel and Manga). Inside of his body, his normal red blood cells turned into a purple spiked blood cells, a sign of becoming a demonic monster. He also grew 10 cm in height. This change in his appearance (along with his personality and abilities) made it difficult for those who knew Hajime before to recognize him at first, only recognizing him because of his voice and facial features.

Shortly after falling into the abyss, Hajime lost his left arm to the Claw Bear on the first floor. He later lost his right eye during his battle against the Hydra on the 100th floor. After completing the Great Orcus Labyrinth and gaining creation magic, Hajime replaced both of them with a mechanical arm made with Creation Magic and an artifact called the Demon Eye.

Hajime's adventure outfit consists of a black coat with crimson-colored linings and trimmings, coupled with a gray blazer and a buttoned white shirt underneath it, along with a cravat terminated by a ring tied around his neck. He wears black pants that have gun holsters attached to them, as well as knee-length black boots. His appearance has been described to look like an anime character, something Hajime is painfully aware of.

After he returned to Earth, Hajime's hair was reverted to its original black color due to Kaori's improved Restoration Magic. He decided, however, to keep his mechanical arm and demon eye, disguising them as his original arm and eye in order to keep Tortus' existence secret from the general public.

Pre-Fall
Hajime was originally very laid back and timid, but was humble, with a kind and gentle heart. Though mild-mannered, he had a special type of bravery and strength of heart that allowed him to sacrifice his own dignity and well-being to protect people from harm. Kaori 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. His strength of heart is evident by his ability to keep calm when his class faced extreme danger from a Behemoth. While Kouki had momentarily been paralyzed by fear, Hajime snapped him out of it. He had a motto of "Hobbies First", and would put his hobbies over everything else, despite being ridiculed by his peers. He was also considered mature by some, especially his true friends. He was lazy at school mainly because his future is already set and he would be likely to work at his father's videogame company. He always comes to school when the class almost started, sleep the entire lesson, and wake up when it's break time or school is over. This is because he stays up late to play videogames or read manga, sometimes helping his father and mother with their work. His grade is average and he doesn't play sports at all.

Post-Fall
"I'll protect you, and you'll protect me. As long as we watch each other's backs, we'll be stronger than anyone. We'll beat down anyone who stands against us and burst our way out of this shitty world!"

- Hajime to Yue

After being betrayed and thrown into the abyss to die because of Hiyama's cowardly betrayal, anger, hunger, fear of dying, and despair drove Hajime to his limit. All these factors mixed with his desire to survive and live at any cost, causing his gentle personality to change into that of a cold, ruthless, brutal, bloodthirsty, unstable and sadistic killer. He abandoned most of his former kind and generous nature, exchanging it for that of a cold and indifferent man capable even of abandoning a person to death without a second thought. This can be seen when Hajime's goal is not to free Tortus from Ehit's tyranny by defeating him. Rather, it is the opposite.

Hajime's only concern is to survive and return to Japan with no concern for the fate of Tortus or its inhabitants. He no longer even cares about his former classmates that he is even willing to kill them without any hesitation, if they become his enemies. He has stated that he will murder all the Humans, Demons and even destroy Tortus itself if he has to. He will show no mercy to anyone, including his own classmates if they dare to cross him. Shizuku and Aiko have even acknowledged he would slaughter them, if they were to attack him at the instigation of the Heiligh Kingdom and the Holy Church. Hajime developed a habit of smiling in front of danger which prompted Shea to call him a new species of monster called a "Predator".

Due to the hardships he had suffered, Hajime developed a firm belief in independence, namely relying on one's own abilities to solve problems and to overcome obstacles independently. Thus, when he was safeguarding Shea's family and clansmen, Hajime opted to train the Haulia Rabbitmen to be strong enough to protect themselves. Additionally, Hajime refused to do anything about Ehit's manipulation of the people of Tortus, stating to Miledi that it is their own problem to solve, and that he has no intention to risk his life for their well-being, as she and her fellow Liberators had. He also refused Chase's attempts to persuade him to rejoin them or teach the Heiligh Kingdom's Synergists how to manufacture firearms to aid them in their war efforts.

Kouki has stated Hajime could have convinced him of Ehit's true nature as an evil god by thoroughly explaining it several times. Hajime simply called Kouki stupid, fiercely criticizing him and his other classmates' beliefs that they must always risk life and limb to protect others as delusional and naïve, stating that it is because they keep holding onto and believing in such ridiculous ideas that they allowed Eri and Hiyama to stab them in the back, nearly leading to their own deaths. Hajime also told Shizuku to stop being so protective of her classmates in the Schnee Great Labyrinth as they must learn to overcome their own trials by themselves in order to attain Age of God's Magic to realize their respective goals.

Hajime also believes that it is strong resolve and determination, rather than power and abilities, that allow one to realize their goals. Therefore, when Kouki criticized Hajime's refusal to defeat Ehit and save Tortus, Hajime took the chance to berate Kouki's indecisiveness, weak will, and misguided faith in his naïve idealisms by pointing out that despite being blessed by Ehit with the strongest powers out of his classmates in the beginning, he keeps screwing up during desperate moments when it truly mattered, such as during Cattleya's ambush and Eri's death trap.

Despite his merciless nature, Hajime cares deeply for his comrades, as they are the last fragment of his lost kindness. Kaori and Shizuku noted that, despite his newfound strength, confidence, and courage, Hajime is always desperate to protect his comrades and to defend against any potential dangers that may befall them, a trait he has exemplified even before his fall into the Great Orcus Labyrinth. As the series progresses, Hajime eventually proves himself to be willing to help the weak and helpless, particularly if his companions coax him into doing it, though he often does it while still demonstrating a cold demeanor. His methods are efficient and merciless, frequently to the point of brutality. He is resistant to guilt trips and appeals to his moral compass, as seen when Kouki repeatedly tries to make appeals to Hajime's morals and fails. Despite outwardly appearing reckless and brave, Hajime is actually quite cautious, taking any possible precaution to prevent disadvantages, even if they are minimal and is not willing to take any unnecessary and futile risk, such as his refusal to part with his techno-magical firearms and artillery when More Nos wanted to buy his weapons, or when Chase tried to persuade him to help the Heiligh Kingdom mass-produce firearms for their war.

Hajime knew that with Ehit's absolute influence over the people of Tortus, giving up his weapons to the Holy Church and Heiligh Kingdom would be an extremely risky mistake, as he knows that they will all eventually be turned against him. Hajime even threatened Chase with death if he ever tried to steal Donner, much to the shock of Aiko and his classmates. Hajime also took the opportunity to tell Aiko of what he learned about Ehit, in order to warn and gain her help & support in warning his other classmates about it. His motives were not altruism, but to minimize the chance that his classmates would turn against him under Ehit's manipulation. Hajime also reluctantly agreed to Kouki's party members' requests in helping them gain Age of God's Ancient Magic as a precaution, in case he needed their help to fight against more of Ehit's Apostles. Hajime also told Shizuku that he preferred to resolve problems early rather than at the last minute before it went out of control, lamenting that Kaori's murder and nearly becoming an undead slave by Hiyama's hands was traumatizing, even for himself.

While Hajime is usually blunt and cold to most people after his transformation and is not above expressing his annoyance with even those close to him, he is very spoiling towards those he loves, his family, or towards people he's become fond of. Though usually cold towards people he meets, Hajime is not above showing respect and behaving courteously towards people he finds interesting. While he usually scoffs at figures in positions, authority and power, he is shown to express respect to authority figures that are competent, cunning and who are willing to help others such as Catherine, Ilwa Chang and Lanzwi Feuward Zengen.

Hajime become a very popular person with women. Kouki, who was popular with women before, lost his fame and become jealous of Hajime. But Hajime didn't want to use this to his advantage and initially, he had eyes for Yue and Yue alone. But after the incident at the Haltina labyrinth, where his feelings for his comrades (harem) were reversed, he realized how much they truly meant to him and subsequently started to accept the romantic attempts of the others around him after accepting Shea as his second girlfriend. This is often shown in how he would flirt with Yue and later his other wives without concern for his surroundings. While he was against Myu calling him "papa", he quickly became a doting and overprotective father to her. When around his in-laws, Hajime is more respectful and patient than how he is with his own birth parents, using polite language when talking with them, something his wives, his classmates and his other close associates still not used to.

While Hajime appears to be one with certain air of arrogance and stubbornness to most people, he can still be "easily talked" into doing things that he'd initially unwilling to do, by his wives and especially Yue. Also, his doting tendencies towards Myu does make him more approachable with children, as shown during his stay in Verbergen. He once took up an impromptu babysitting of a group of beastmen children, who were fascinated by the stories of his adventures and small trinkets he is able to synergize at will. The scene of children taking an afternoon nap with Hajime was too adorable for his wives, as it reminds them of the future when they too have kids with Hajime.

One other trait that remains unchanged about Hajime is that he still remains an Otaku - something that Kaori points out, while Yaegashi teases him with. Hajime bases most of his creations and even his appearance off things from anime, manga, and video games. He's even gone out of his way to create massive and extremely difficult-to-make artifacts, simply because it would be cooler. Hajime feels very self-conscious about this, as he's fully aware it's all true. Being a Synergist at heart as well, Hajime can become so passionate about what he decides to make that he won't stop or compromise until he finishes what he started. This has led him to go overboard on more than one project and add many pointless but cool features to his Artifacts.

Due to his Otaku nature, Hajime has several fetishes that can cause him to become aroused and excited. He has a strong preference to beast-girls, especially bunny girls as seen when he was learning about the various races of Tortus, lamenting at the harsh conditions that the beastmen were forced to endure. Even after his transformation in Orcus Labyrinth, he still retains this preference which is shown when he starts fondling Shea's bunny ears. This habit grows much more, especially after Shea becomes his second lover. He also has a fondness of maids, as was seen when he became excited and nearly ogled a Heiligh Kingdom royal maid after she served him a drink. It was due to his obsession with maids that he attempted to inherit Oscar Orcus's will of creating a maid golem. He succeeded by creating Freesia, a human-shaped Grim Reaper. Due to his maid fetish, he created the Fleur Knights, a group of combat maids which consisted of beautiful women which he trained.

 After Story 

During the Great Schnee Labyrinth, it's revealed that he has some doubts over whether or not he can live in Japan due to how strong he became and was scared of being referred to as a monster. However when he returned from Tortus, he shows his family the friends & family that he made while exploring Tortus. His parents are very accepting, having heard of his side. Hajime is very glad that his parents aren't upset of what he became of nor did they fear him.

Hajime became the leader of the Returnees - comprised of survivors amongst his classmates and the wives who came along to Earth with him- and get back to his high school life with classmates, with the addition of Yue and Shea joining his class that make up entirely of Returnees. His classmates universally look up to him as their leader, amongst them Hajime's "Demon Lord" moniker is equal part of meme as a sign of respect, which Hajime would regularly play along. Whenever a certain "soul sister" came to challenge Hajime only to suffer humiliation by his hand (which usually quite literally so), the classmates would joke that she must be a "new hero" for only those who has a hero job class would dare to challenge a "Demon Lord".

By using his skillset as Synergist he co-opt several business operations, including a successful one that involves jewelry with Tio and Remia. Hajime have made enough wealth that not only allowed his family (eight wives, Myu and at least six more children in six years time) to live comfortably and financially independent from his parents, but also to enjoy university life with Yue for no other reason than just to enjoy campus life with her.

Hajime would continue his Synergist trek after returning to Japan. Now with the comfort and safety, he would continue to tinker his arsenal if not also build further upon it. It is known that he put a constellation of those orbital-based weapon platforms in Earth's orbit, which he doesn't have the heart to tell his father such when the latter learned what kind of WMD-grade (Weapons-of-Mass-Destruction) firepower he put to use during the epic battle to save Tortus.

Physical Abilities

 * Mystical Mutation - In the Great Orcus Labyrinth, Hajime devours numerous powerful Demonic Beasts, manages to survive the lethal process due to the Ambrosia and his iron forged will. As a result, Hajime's constitution was mutated by the magic of the monster, granting him a tremendously high status, even breaking pass the level 100 limit. At the costs of his mutation, he will no longer be considered as human and no longer be afraid at anything anymore.
 * Immense Strength - After continuously devouring many powerful Demonic Beasts and absorbing their powers, by the end of conquering the Orcus Labyrinth, Hajime gained tremendous superhuman physical power that is completely monstrous and inhuman, his base strength being twelve times far superior to Kouki Amanogawa who is Ehit's strongest "hero", surpassing even Tio the strongest dragonborn in her dragon form, able to carry his oversized Pile Bunker or heavy artillery such as Orkan with little effort. Even without resorting to weapons, he can overpower the strongest humans, beastmen, and monsters with pure physical might, blocking a zombified Meld's swordsmanship who was the strongest Knight of Heiligh Kingdom with only one finger, throwing small harmless objects such as sugar cubes with extreme force to knock down knights. When using his true powers, Hajime can easily break bones and strike with enough force to rupture his enemies' internal organs even Humans who were blessed by Ehit with enhanced physical power, such as when Hajime broken almost all of Hiyama's bones and damaging his internal organs severely, as he brutally beat Hiyama up and gripped his neck to lift the latter with only one hand with no efforts. In the Schnee Labyrinth, Hajime easily overpowered a Limit Break-enhanced Kouki without even using his full strength, bypassing the enhanced protection of Kouki's Limit Break enhanced durability, Physical Resistance Skill and Divine Armor which is the strongest armor type Artifact sending him crashing into an icy wall with one kick pulverizing it and defeated him without sustaining injuries or efforts when brutalized the so-called "chosen hero". After killing Ehit and his servant, Alva, Hajime now holds the power to kill gods or immortal beings with his newly-acquired reputation as the "God Slaying Demon Lord". Hajime can easily defeat weaker enemies with just one hit even in large numbers such as Yaegashi Family's Dojo's students and bullied the Soul Sisters both groups who are annoying to his wife, Shizuku Yaegashi. Hajime has carried anyone without even getting exhausted nor physical strain when he carried Yue and Shizuku (while she was asleep). Hajime's strength has no equal as he is undefeated and never lost to anyone as well-being the strongest and not even Kouki can defeat Hajime or surpassing him either. Hajime can also break normal swords, shields, spears and armors with his bare hand as he broke Kondou's spear and both Meld and Hiyama's swords. No matter how his enemies were strong or durable, Hajime can bypass his enemies' defensive abilities and defeating them effortlessly, as he did in his second fight against Kouki. According to Ahat, Hajime is far too powerful than she expected when killed Noint. His strength is too powerful when he broke from spells includes the Holy Church's powerful spell when they intervene his fight with Noint as he brutalized them effortlessly.
 * Immense Speed - Hajime's speed and reflexes are also augmented to be extremely formidable, his Agility being at least twelve times faster than one of his wives, Shizuku Yaegashi, supplemented with his speed-oriented skills, making it impossible for most enemies to detect his movements in battle. Even his overpowered classmates, such as Kouki, couldn't so much as sense Hajime's movements.
 * Immense Durability - Hajime has gained superhuman physical durability, capable of withstanding attacks that would prove fatal for most people. Hajime's durability is at least 12 times tougher than Ryutarou Sakagami. He didn't receive any sort of injuries from feeble attacks such as Cattleya's most powerful attack, Kouki Amanogawa's strongest attack and Daisuke Hiyama's fireball as his body acts like armor, and he felt nothing but annoyance to him from those weak attacks even attack are not strong to even hurting him. When using his defensive abilities, Hajime's body becomes strong enough to handle attacks from one of God Apostle while only receiving minor injuries which only nicked him a little. Even when Freid ambushed him while got his guard down, it wasn't enough to kill Hajime when he is still able to fight with his injuries.
 * Immense Endurance - Due to his countless brutal experiences in the Orcus Labyrinth from the agony of consuming monsters to withstanding numerous life-threatening injuries from fighting all the powerful monsters, Hajime has attained tremendous tolerance to grievous pain. Augmented with his mystically mutated vitality and defense status, Hajime can withstand most attacks with only minimal discomfort.
 * Enhanced Senses - After continuously devouring many different types of monsters throughout Orcus Labyrinth, Hajime has developed superhuman senses. From having to fight different types of enemies that could completely hide their presence throughout Orcus Labyrinth, Hajime has honed his senses to the point where he can easily notice things before almost everyone else, with only Shea having better hearing due to her long ears.
 * Immense Mana - After continuously devouring many powerful monsters throughout the Great Orcus Labyrinth, Hajime's mana developed to extremely powerful and massive levels, far surpassing Atavists such as Yue, Shea and Tio, all of whom have powerful mana themselves. His original sky blue mana changing to crimson color. When he releases his mana, it's powerful enough to block the immense mana pressure released from Noint, God Apostle, protecting Aiko who was about to fall unconscious. When enraged, he was able to cause all his classmates, who had overpowered cheat abilities to freeze in sheer terror. His mana capacity and regeneration are vast enough for him to operate the "Fenrir" flying craft, which consumes an immense amount of mana to travel between locations.
 * Genius Intellect - While his intellectual ability in academic studies is average, Hajime has proven himself to be an extremely clever genius in engineering. He has immense scientific knowledge which was self-taught from manga, anime, movies and video games. Hajime's intuition is also extremely accurate and spot on, as he was able to correctly deduce that one of his classmates is purposely responsible for the apparent misfired fireball that led to his fall into the deepest depths of the Orcus Dungeon and the reason being jealousy towards Kaori's infatuation towards himself and would also commit any horrific atrocities to force Kaori to become his sex slave when Hajime warned Aiko about it. He would later be proven correct when Hiyama had assisted Eri in massacring and zombified all the Knights of Heiligh Kingdom and also the death trap for their classmates and even murdered Kaori herself in order to make her his personal undead sex slave, a fact which even the extremely sharp minded Shizuku had noticed only when it was too late. Hajime was also the first to noticed that the Humans and Demons of Tortus were actually worshiping the same Evil God Ehit, who is actually posing as two different gods in order to manipulate the two race into fighting and killing each other for millennia after learning about Ehit's callous apathy towards the destruction of the Heiligh Kingdom, who were supposed to be his most faithful worshippers, from Noint and that Ehit would send even more Apostles after him. This would be proven when Hajime succeeded in slaying Noint and stopping Freid Bagwa's invasion of the Heiligh Kingdom, Ehit send five hundred Apostles to support the Demons as reinforcements to not completely annihilate the Humans who were Ehit's worshipers but also to eliminate Hajime. Hajime has also shown to be an acute judge of character, as he noticed the real reason why Tio joined his party was because she was hoping to uses him in her revenge against the gods, something the others only realize after she confessed it herself. Hajime also chose to confide in his teacher Aiko about the true reason of his refusal to rejoin them by telling her the secret he learnt from Oscar about Ehit's true nature as a twisted Evil God as he fully understands that Aiko who is extremely devoted to her students will absolutely believe his words as he is also one of her students whom she prioritized above all else and later Kaori since she held immense love towards Hajime will also believe him. When Kouki questioned why he had not told them about Ehit's true nature earlier when they reunited in the Orcus Dungeon, Hajime stated that Kouki will never want to believe him by elaborately pointing out his misguided sense of justice, inability to differentiate between good and evil and most of all his habit of conveniently twisting and interpreting things to fit his worldview, and will even get angry at him for seemingly slandering the god who had chosen him to be the Hero, a statement which even Kouki himself could not deny. Despite his average grades, he learned the Norse Mythology when he considered Noint similar to Valhalla's Valkyries.
 * Master Inventor - Hajime is an extremely resourceful and innovative inventor, combining his scientific knowledge learned from countless manga, anime, and movies with his transmutation skill to create various powerful techno-magical weapons and other advanced magic-powered machinery similar to Earth's modern military technology as well as science fiction technology. Hajime has shown to be an extraordinarily talented firearms designer, having managed to make firearms and artillery with unique customizations such as Donner & Schlag break action revolvers designed for mid-air reloading customized with make-shift swing out cylinders to incorporate the greater firepower of swing out revolvers, incorporating shotguns into Oscar's magical prosthetic arm artifact as well as Shea's Drucken War Hammer, modified the new Schlagen anti-material rifle to function as a sniper rifle by mounting a telescopic scope to shoot from long distances, designed Metzelei as a handheld portable Gatling Gun. Hajime is also a self-taught genius in vehicle engineering, having designed Steiff motorcycle, Brise pickup truck, a submarine and most of all Fenrir airship based on science fiction and military technology.
 * Master Craftsman: Hajime has trained his craftsmanship as a Synergist to uttermost perfection, due to his earliest attempts to create modern firearms which are extremely difficult to create in comparison to swords and armors, eventually succeed after countless trial and error. With unrivaled precision and dexterity in his craftsmanship, Hajime became an outstanding master gunsmith. Combined with Age of God's creation magic, Hajime can create techno-magical artillery of tremendous power. In addition to guns, Hajime can also apply his skills into crafting melee weapons and armours of the highest quality including refining them to be much more powerful as well as perfectly repair ancient artifacts. Hajime's masterpieces as a Synergist include his signature revolvers Donner and Schlag, Shizuku Yaegashi's Black Katana, Shea Haulia's Drucken War Hammer, and Suzu Taniguchi's Tessen Folding Fans. He is currently considered the best craftsman on Tortus, so much that all of the Heiligh Kingdom's finest Synergists including Volpen wanted Hajime to accept them as his apprentices after appraising his craftsmanship in Shizuku's Black Blade Katana and perfectly restoring the Heiligh Kingdom's barrier artifact in a matter of seconds. His craftsmanship extends to handicrafts such as jewellery type artifacts he made for his harem which are complex and fanciful. He also dabbled in architecture as he renovate the Nagumo house to expand it for the sake of his harem including an underground dimensional basement impressing Tomoichi who is a renowned architect.
 * Master Tactician - Hajime is an extremely pragmatic tactician, relying on unorthodox yet extraordinary strategies allow him to outsmart most enemies, including the God Apostle Noint. He managed to expose the truth that had most humans to turn against the God Ehit which succeeded with the help of his teacher, Aiko and Princess Liliana. Before his transformation, Hajime make cunning uses of his Transmute ability to first immobilize his target before killing it, something that impressed the knights who didn't expect him to be of much help at the time. This tactic worked even in the true Orcus Labyrinth, where the monsters were stronger and weren't weaken by someone beforehand. During the battle against the Behemoths, Hajime was able to quickly figure out a way to hold it back so his classmates could launch a barrage of magic attack against it when they were ready, which mostly worked if it wasn't for Daisuke trying to kill him. Hajime is good at taking advantage of his environment to his advantage, as he often used the terrain to ricochet his bullets so they can hit enemies who are dodging. During his battle with a doppelgänger-enhanced Kouki, he was capable of taking advantage of Kouki's collapsed mental state which left his attacks predicable, to easily overwhelm him. Hajime easily tricked the demons of Garland with the false surrender to unleash a massacre upon the demons and rescued the hostages.
 * Master Marksman - Due to his experience in fighting countless powerful monsters with a revolver and further relentless training with Yue in mastering precision shooting after conquering the Orcus Dungeon, Hajime has outstanding marksmanship in dual-wielding his techno-magical revolvers, Donner and Schlag to destroy large numbers of powerful enemies in quick succession with deadly accuracy. During his battle against Noint, Hajime was able to aim at a certain point on her swords and repeatedly shot at it during their mid-air, high-speed close-combat fight until her swords snapped. Hajime can also wield his larger, more powerful firearms with equally amazing accuracy, even when he's holding them with one arm each. Hajime can ricochet his bullets off surrounding walls, allowing him to hit targets from their blind spots. He can also pinpoint his enemies' weak points, such as Noint's crystal-like heart and Kouki's kneecaps and shoulder. He is capable of shooting things without looking at them, as was demonstrated when he shot the Frost Eagles that were attacking Shizuku or during his battle with a corrupted Kouki. Hajime's marksmanship are so immense that Shizuku wondered if Hajime had a secondary Gunner job which granted him such skill.
 * Stealth Expert - Due to his mastery of his "Hide Presence" skill, Hajime is capable of masking and manipulating his presence to avoid detection. He is capable of easily infiltrating secure prisons, as he demonstrated when he rescued Aiko and later Cam and the other Haulia from their imprisonment.
 * Master Hand-to-Hand Combatant - Having never received any form of training before being summoned to Tortus and falling into the abyss, Hajime had self-taught himself how to fight. His fighting style has been regarded as the height of rationality, focusing on effectiveness. Hajime trains extremely extensively to incorporate kicks into his fighting style, which he combines with his monstrous superhuman physical prowess and leg enhancement skills, allowing him to overpower his enemies even those who were blessed with superhuman physical abilities without any effort. He easily brutally overpowers Daisuke Hiyama, a summoned Hero with enhanced abilities by breaking his bones and damaging his internal organs without resorting to his revolvers as Hajime's hand to hands combat skills are considered to be too dangerous. He can fight Shea, who has become extremely skilled at martial arts, on equal footing in a pure contents of hand-to-hand. When Kouki went berserk at the Frost Cavern of Schnee and fused with his powered up copy, Hajime still easily beat up the dimwitted hero without any trouble or trying to kill him even sustained no injuries. Though all of Kouki's stats being increased enough to rival Hajime's own, Kouki's tattered mental state made most of his attacks predictable, making them easy dodge and counterattack. During the final part of the Frost Cavern of Schnee, Hajime defeated his copy by fixing all the weakness and wasted movements in his fighting style, becoming better than when he started the fight.
 * Expert Artist - While still inexperienced, Hajime possesses incredible artistic skill which he has learnt and developed by handling the illustrations of the game produced by his father’s video game company and helping assist his mother who is a famous shoujo mangaka for five years. Hajime would apply his artistic skills into drafting maps for exploring the Labyrinths on stone tablets, blueprints for his weapons and devices, and even incorporating aesthetic designs in his equipment.
 * Training Methods - From his experience in fighting monsters Hajime has developed unconventional yet effective training methods which he used to train himself for two months after conquering the Orcus Dungeon into a master marksman and hand-to-hand combatant. Hajime would later train his party, the Haulia Tribe, the Fleur Knights, Shizuku Yaegashi and Ryutarou Sakagami. These results of training made his pupils to be strong. According to Ryutarou Sakagami, Hajime is considered to be a pupil of "Drill Sgt. Gunnery Hartman" due to his harsh training methods for others to become strong physically and mentally. Hajime could train the timid & pacifistic Haulia Tribe into a deadly group of master assassins by weaponizing their natural skills in stealth and agility. Routing enemies into ambush, subterfuge and sneak attack maneuvers in just ten days.

Combat Styles & Techniques

 * Gun Kata - This is a martial arts where the user uses firearms to fight.
 * 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.
 * Ultra-Fast Quick Draw - A technique in which he fires Donner so fast that each round of six bullets had only one gunshot noise accompanying it.
 * Polygon Rebound - A technique in which he correctly calculates all the angles of his shots, so that occasionally his bullets ran into each other and ricocheted off to hit different targets with perfect accuracy.

 * 108 Harassment Demon king-style - It is one of the harassment styles developed by Hajime after the battle with Ehit in order to deal with problems. There are 108 harassment styles in total, but only a few of them are revealed so far.

Notable Harassments

 * 108 Harassment Demon Lord-style - "The Demon Lord is So Red-Like"

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 to react and give 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.


 * 108 Harassment Demon Lord-style - "Gag Bullet"

"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.


 * 108 Harassment Demon Lord-style - "Welcome to My Battlefield"

(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. The space in a radius of three kilometers around Hajime as well as until the height of three kilometers 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 out~, let us out from here~?" ''while hitting on the invisible wall.


 * 108 Harassment Demon Lord-style - "Everyone Died Here You Know"

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.

It was said that if a mistake was made, this harassment could even make the planet totally broken.


 * 108 Harassment Demon Lord-style - “Make a Contract With Me and Become a Magical Girl! (Forced)”

It brainwashes a person into thinking that they are a pop star. Hajime first uses it against some government agents that try to spy on him.

Ancient Magic

 * Creation Magic - one of the "Ancient Magic" originating from the "Age of God", which grants control over any object, structure (be it physical or magical) or mineral, allowing the user to shape or transform them in any way they wish. It is the only form of magic which allows the creation of an "Artifact". The true power of this magic is the ability to 'interfere with any inorganic material'. As a Synergist, Hajime has high compatibility with this magic and uses Creation Magic to generate his own supply of special and rare minerals for his equipment such as Taur, Shtar and even Azanthium without the need to mine for it in locations such as the Orcus Dungeon, Hajime can also use Creation Magic to enchant spells or Skills such as the other Ancient Magics into objects or existing Artifacts to make them stronger.
 * Gravity Magic - One of the "Ancient Magic" originating from the "Age of God", it gives the user control over gravity. The true power of this magic is the ability to 'interfere with the energy of star', and just not gravity. Theoretically, it could also interfere with things like earth vein or terrestrial heat, bedrock or magma; and it isn’t impossible to use this magic to purposefully generate earthquake or volcano eruption.
 * Spatial Magic - One of the "Ancient Magic" originating from the "Age of God", it allows the user to manipulate the space around themselves, allowing them to either bend or expand the space near them or move themselves to another space or location. The true power of this magic is the ability to 'interfere with the boundary'. Meaning it can allow the user to manipulate anything, like the elimination of race-creature gap, or formulating new boundary to create a spirit world; it's possible to achieve those kinds of things.
 * Restoration Magic - One of the "Ancient Magic" originating from the "Age of God", which allows the user to restore the state of anything to either its previous or original condition. The true power of this magic is the ability to 'interfere with the time', meaning it has the ability to manipulate the time of anything, anyplace or anyone to a point the user desires to.
 * Spirit Magic - One of the "Ancient Magic" originating from the "Age of God", which allows the user to manipulate the soul of a living being directly. It's possible to revive a living being back from the dead (time restriction applicable), or transfer the soul of a living being from one body to another, or even into a non-physical body as well, practically granting any living being immortality. The true power of this magic is the ability to 'interfere with the negative material possessed by living thing'. To be more specific, this magic could also interfere with things like energy inside the body that was mana, heat, electricity, then thought, consciousness, memory. Those who have mastery over this magic can even create an artificial consciousness, and allow it to inhabit anybody they wish.
 * Evolution Magic - One of the "Ancient Magic" originating from the "Age of God", which allows the user to enhance or evolve all other forms of power, be it strong or weak. It can work on even other "Ancient Magic" as well, boosting their power and scope. The true power of this magic is the ability to 'interfere with the information about existing things'. This magic enhances or evolves an ability or power by a stage of 1, by interfering with the targets information, and the increased it one-by-one stage. Hajime has used this magic to further improve all his Artifact, making them all far stronger.
 * Metamorphosis Magic - One of the "Ancient Magic" originating from the "Age of God", which allows a user to remake the form of a normal being and reform them into a different form. Normally, it's used to remake a normal organism and turn it into a monster, or even manipulate the magic stone of a monster and remake them. But the true power of this magic is the ability to 'interfere with any organic material'. Meaning not only animals, but it's also possible to remake plants or intelligent beings, and reform their structure as needed. Even byproducts of organic material, like paper or food, can also be manipulated by this magic. The magic stone which gets created during the process is just a byproduct of the process.
 * Concept Magic - It is a form of "Ancient Magic art" which is a combination of many other ancient magics. The main ability of Concept magic is that allows one to interfere with the laws of the world and impress concepts upon it. By raising up a powerful wish or desire with Spirit Magic and Evolution Magic, it can be raised to a level of a concept before being forcefully materialized with magical power. However, since the user's desire at of the time of use, is used as the base of the magic, to raise up and create the concept, the spell may not remain stable in subsequent uses, thus a single spell can only be used once under most circumstances. However, if the desire is still needed, it can be used more than once, like in the case of Hajime's crystal key which had the concept of "I want to return home" in it, was destroyed by Ehit he was still able to recreate the crystal key again because his desire of wanting to return home was still there. It should be noted however that concept magic requires the user to concentrate on raising up their wish in order to materialize the concept, as such it wouldn't be useful in a battle where the user is under attack. Also, some concepts aren't possible to materialize by the user on their own, for example, Hajime could only make degraded versions of the crystal key without Yue.

Spells/Attacks

 * Deny All Existences - A "Concept magic" created by Hajime, through Evolution magic, which overwrites other's information from "Exist" to "Non-Exist". Hajime combined this with his Transmutation and created several ultra-thin chains that inflict the magic on contact. Anything the chains touch will feel excruciating pain, even if they normally wouldn't, and quickly be cut into ever-smaller pieces until nothing is left.

Before the Fall as a Human
Hajime's base stats growth rate before his fall into the Orcus Labyrinth's lower floors when he was a human.

After the Fall and becoming a Human/Monster Hybrid
Hajime's base stats growth rate after his fall into the Orcus Labyrinth, when he became a monster by consuming the meat of monsters.

Note :-


 * The base stats given above aren't Hajime's current stats, as the last time the author provided stats for him in the Web Novel was before he acquired "Evolution Magic" from the Haltina's Labyrinth.
 * Hajime's base stats increased because of his usage of Skills "Limit Break", which triples his base stats and "Overload", which quintuples his base stats. He can also further boost his base stats with the help of "Evolution Magic" and by using a mineral supplement drink which he created, named "CheatMate", that has the ability to double a person's base stats.

Quotes

 * (To Tio Klarus): "Just go back to your den. Or just die and return to the earth!"
 * (To Cattleya about whether he's still human): "No, actually, I'm not."
 * (To Cattleya): "I’ll kill anyone that makes themselves my enemy, even the gods themselves. I can’t imagine someone stuck as their pawn is much of a threat."
 * (To Kouki Amanogawa): "God, you're persistent. Amanogawa, you're not mad about me killing her, are you? You're mad at yourself for not being able to kill her and pretending you've got a better reason for being pissed."
 * (To Kouki Amanogawa): "It's kill or be killed in this world. You've got to kill your enemies. What's wrong with that?"
 * (To Kouki Amanogawa): "It’s my policy to kill anyone who becomes my enemy. Unless I have a good reason not to, I’ll make sure to kill them. It doesn’t matter whether they’re good or evil, or whether they can resist or not. The moment you show mercy is the moment you die. I learned that the hard way at the bottom of the abyss. Those are just my values though, and I have no intention of pushing them on anyone else. Still, if you plan on standing against me just because you don’t like that, then... Even if you are my former classmates, I won’t show you any mercy."
 * (To Myu after hearing her call Tio 'sexy neglecting'): "Myu, where the hell did you learn those words?!"
 * (To Noint): "I’d like to see you try, God’s Puppet!"
 * (To Noint): "Looks like this ‘Irregular’ was more than you could handle."
 * (To undead Meld Loggins): "So she got you too, huh? What a shame."
 * (To Eri Nakamura after wiping out her slaves) "So?"
 * (To Eri Nakamura): "I don't care what drove you to this, I don't care what your motives are, and I don't have time to listen to you explain them. If that's all you've got to say... then die."
 * (To Daisuke Hiyama before kicking him): "Shut up!"
 * (To Daisuke Hiyama): "It wouldn't have mattered if I was here or not, Hell would have freeze over before you'd manage to do anything worthwhile with your miserable existence."
 * (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 Daisuke Hiyama after punching him): "Good luck surviving out there. Knowing you, you probably won't make it."
 * (To Freid Bagwa after murdered 100,000 demon troops): "The foolish one is you, you big fool. When exactly did I say that I was allied with the Kingdom and these guys here? Don’t just selfishly categorize me with them. If you want a war, then go right ahead. However, if you get in my way just like now, I’ll erase everything. Ma~a, I’m not free enough to waste my time on 1 million opponents though, this time around I’ll let you off so hurry up with the remaining people and get lost. You’re the commander of the army right?"
 * (To Kouki Amanogawa): "If I did tell you, will you even believe me!?"
 * (To Kouki Amanogawa): "After all, we are talking about you who love to interpret things to your own convenience. The god Ehit whom the people of this world believed in and also specially chose you to be the Hero was a twisted evil god, and that your heroic efforts are completely meaningless, if I told you that, you definitely wouldn’t have believed me. You will probably get mad at me instead. Am I not wrong!?"
 * (To Kouki Amanogawa and his other classmates): "Are you stupid? Why must I go to such trouble just to suit your delusion? Don't tell me that just because I am a classmate, you all think that it is natural for me to always risked my life and limb to help all of you. If you keep believing and spouting that sort of ridiculous crap, its gonna end up just like what happened with Hiyama."
 * (To Kouki Amanogawa): "If I have power, I should use it for justice? It’s because you think like 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."
 * (To Kouki Amanogawa): "Listen up, Amanogawa. I don’t care about your justice, and I have no interest in arguing with you about what’s right and wrong. We’re not friends, we’re not comrades, and we definitely don’t believe in the same things, so I have absolutely no intention of doing something just because you say so. All I did was allow you to accompany me for a bit. Don't you dare make me angry. The next time you do something stupid... I’ll break your arms and legs and send you back to the kingdom."
 * (To Haulia Tribe): "Cam, and the Haulia tribe. All of this guys odd strategies are hereby rejected. You all directly point your blades at the Emperor’s neck. Grab his hair and drag him down, his relatives, his friends, pin down all of his subordinates in front of him. Suppress the Imperial castle, if help does not come, the Empire would be finished by the end of night! Engrave it into their bones that the Haulia tribe can finish them anytime they want! Anywhere in this world, there is no safe place, if you antagonize the Haulia tribe, the neck cutting parade begins, force them to write it into their Empire’s history!"
 * (To Shea Haulia): "You’re irreplaceable to me, Shea. I don’t want to hand you over to anyone else. Now that you’ve become special to me, I won’t ever let you go. I hope you’re ready."
 * (To the corrupted Kouki Amanogawa after he shot one of his kneecaps) "Pathetic. Why don't you use the extra feature I added to your equipment? You'd put up more of a fight that way at least."
 * (To Kouki Amanogawa): "Moron, You already lost to temptation."
 * (To Kouki Amanogawa): "First, I decide what it is I want. Then, I decide what it is I need to do in order to make that happen. After that, all that’s left is to do it. There’s no point in worrying about whether I can do it or not. If I have time to worry, I have time to think about what my next move should be. I’ve decided. I’m going to back home to Japan with Yue and everyone. I’m going to show them all the cool things Earth has, and introduce them to my parents. That’s what I’m putting my life on the line for. I don’t have time to care about ‘what ifs’ that even my own subconscious doesn’t have the answers to."
 * (To Kouki Amanogawa): "I know better than anyone I’m just putting the problem off instead of solving it, and that this isn’t a very human line of thought to begin with. But that’s still no reason to stop here."
 * (After defeating his doppelgänger): "No matter what future’s waiting for me, I won’t stop struggling."
 * (To the corrupted Kouki Amanogawa): "When you're this stupid, there's no point even pointing out your stupidity. But let me say just one thing. Who do you think you are, saying Yue's name without honorifics? You bastard."
 * (To Freid Bagwa): "What kind of an idiot would head straight into the enemy stronghold when they know it's a trap? If we're gonna fight anyway, we're better fighting here. Let's settle this once and for all, Freid!"
 * (To Adul Klarus): "I want Tio."
 * (To Adul Klarus): "Tio belongs to me now. If you don't like that, you 'll have to steal her back from me. I'll accept your challenge anywhere, anytime."
