After being called once incompetent and betrayed by one of his classmates, Hajime falls into the abyss where his journey to become the strongest begins.

In the beginning and before his mutation, Hajime has a miserable life in school and Tortus when he was bullied by Hiyama and his gang after he got a lot of attractions from girls including Kaori Shirasaki and Shizuku Yaegashi. When he was left for dead and suffered, Hajime turned into a monster.

After Hajime eaten many most powerful monsters and made weapons from monsters' essences, he gained too much power and mutated that break even level 100 meaning he become more powerful beyond of that of a god as he killed Ehit and became a human/monster hybrid but turned from a pure good person into a ruthless killer when he vowed that he will kill all those who get in his way or harming his friends (harem).

When learned from the Liberators of Hajime and his classmates were being used by the god, Ehit. Hajime abandoned all respects for the god and hates him and all others gods as he swear to kill them all if they getting his way.

Hajime became even popular to girls more than Kouki Amanogawa due of his new appearances. After Story, he married 8 times and Yuka as his mistress. He became a step-father of Myu after marrying her mother, Remia.

Appearance
In the beginning of the story, Hajime had black hair, brown eyes, and a slim body type. He also had a kind face and attitude. After falling into the abyss and eating the twin-tailed wolf monster, his body began to wither away. After he drank the ambrosia in the abyss to counter the effects of the monster meat, his body began to heal and grow stronger in the process. Due to the stress of this repeated revitalization, his hair turned white, a condition called Marie Antoinette syndrome. His eyes also turned red and his body gained tattoo-like red veins, a sign of becoming a demonic monster. These red marks also grant Hajime the ability to use magic without needing to use chants or incantations. He also grew 10 cm in height and gained a muscular, toned figure. The huge 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 (and that's only after taking a closer look).

Shorty after falling into the abyss, Hajime lost his left arm to the Claw Bear on the first floor. He would later lose his right eye during his battle against the Hydra. After completing the Great Orcus Labyrinth and gaining creation magic, Hajime would replace them with a mechanical arm and an artifact called the Demon Eye, respectively.

After he returned to Earth, Hajime's hair and eyes reverted back to their original color due to Kaori's restoration magic. He decides, however, to keep his mechanical arm and demon eye, which are disguised to look like his original arm and eye.

Original Personality
Hajime was originally a weak and average person with a timid and tolerant personality but with an extremely kind and gentle heart. While mild-mannered, he has a special type of bravery and strength of heart that would allow him to sacrifice his own dignity and well-being to protect a child 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 perilous dangers from a Behemoth, while Kouki had momentarily stood paralyzed by fear until being 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. He was also considered mature.

Current Personality
After fell into the abyss and suffered when lost his left arm due to Hiyama's betrayal, Hajime abandoned his kind and gentle attitude and adopted a newly personality as cold, unstable, ruthless, cruel, uncaring and sadistic murderer. He will kill anyone who gets his way of his goal to return back to Japan. He shown his sadistic side after he killed monsters and eaten their meat for his mutation. He doesn't care for vengeance as he viewed himself to be more powerful than his now useless classmates. Learned from the hologram Oscar of the gods, Hajime doesn't worship gods but rather hold hatred toward the gods and will kill them all. Even though reunited with his classmates (only to indebted Kaori), Hajime still doesn't care about his weak classmates (except for Kaori and Shizuku) and give them a proper warning if they get in his way, he'll kill them caused them to fear Hajime even caused his former bullies to be afraid of him. Hajime will also kill those who lay a single finger or harms his comrades (harem) such as he murdered the traitorous idiot Hiyama for killing Kaori Shirasaki. Despite he was once human, Hajime doesn't care of saving lives for those who are manipulated by the gods and unlike the Liberators, he will kill them all when he unleashed a massacre upon both human and demon worshipers (pawns) of Ehit and brought destruction upon Tortus during the war on Heiligh Kingdom. Hajime viewed all races of Tortus (including the gods) as weaklings after he murdered Noint. In his sadistic side, Hajime mocked and provoked his enemies to lead them to their deaths. He has no tolerances for empty idealism, emotional weaknesses or cowardice. He got disgusted by Kouki's idiotic ideals. He called Hiyama and his gang worthless and weak as well exposed Hiyama's greatest fear of his responsible for Hajime's "fall" and left him for dead. He doesn't take orders from those who are inferior to himself. He refused to return to the so-called "Hero Party" to being pawns for Ehit's twisted entertainment. After returned to Japan, Hajime is at least a bit merciful as he will pulverize anyone who dare challenge him and left them to be humiliated as he did with the students of the Yaegashi Dojo and bullied and completely humiliated the so-called "Soul Sisters" in public who are annoyances to one of his wives, Shizuku Yaegashi

Hajime has immense love for his parents. They were responsible for Hajime to become an otaku. While almost dying, Hajime vowed that he will return back home to Japan and reunite with his parents, even if it means to abandoned his kindness and his morality to become a genocidal mass murderer and a god slaying destroyer.

Despite being a ruthless and uncaring murderer, Hajime is still honorable as he has what's left of his kindness. He cares deeply for his comrades (harem). He is a protective father of Myu. He allowed Kaori Shirasaki (his childhood love interest during middle school and future wife) to join him. He let Shizuku (one of his lover and future wives) to keep his created sword, Black Blade as a gift.
