OVA
Description
Hajime Nagumo was initially a timid yet kind-hearted Japanese high school student. He possessed a gentle nature and a unique bravery that drove him to sacrifice his own safety for others, despite recognizing his physical limitations. He lived by the motto "Hobbies First," prioritizing interests like video games and manga regardless of peer mockery. Academically average and disinterested in sports, he often arrived at school just before class and slept during lessons due to late nights spent on hobbies or helping his parents.
Transported to the fantasy world Tortus alongside his classmates and teacher, Hajime received the commonplace Synergist job class focused on transmutation magic, while others gained combat abilities. Betrayed during an expedition into the Great Orcus Labyrinth, classmate Daisuke Hiyama pushed him into a monster-filled abyss. Presumed dead, Hajime endured extreme isolation, starvation, and lost his left arm to a Claw Bear. Driven to desperation, he consumed monster flesh, triggering a painful mutation requiring constant healing from Ambrosia. This transformed him physically: his hair turned white, eyes became crimson red, and red, vein-like markings appeared. He grew taller and more muscular, height increasing from approximately 165 cm to 175 cm. He later lost his right eye fighting a Hydra on the labyrinth's 100th floor.
This trauma fundamentally altered Hajime. He shed his former kindness, adopting a cold, ruthless, and pragmatic demeanor solely focused on survival and returning to Japan. He became willing to kill anyone obstructing his goal, including former classmates, and declared he would destroy Tortus if necessary. He developed a habit of smiling dangerously in threats, earning the moniker "Predator." He embraced self-reliance, refusing to solve others' problems unless they impacted his objectives. He disdained idealism, criticizing classmate Kouki Amanogawa's naive heroism as a dangerous delusion.
Within the labyrinth, Hajime discovered and freed Yue, a vampire princess imprisoned for 300 years. She became his first companion and the anchor for his remaining humanity. His Synergist ability, combined with Earth knowledge, allowed him to create sophisticated firearms and artifacts like the revolvers Donner and Schnee, the railgun Schlagen, and prosthetic replacements for his lost arm and eye. The prosthetic arm and magically disguised Demon Eye became permanent. He later accumulated more companions: Shea Haulia, a rabbit-eared warrior with future-sight; Tio Klarus, a perverted dragon devoted to him after defeat; Kaori Shirasaki, a classmate whose unwavering belief persisted; and Shizuku Yaegashi, Kaori's pragmatic friend.
Conquering the Orcus Labyrinth revealed the deity Ehit as a manipulative tyrant. Hajime resolved to conquer the remaining labyrinths to gather ancient magics for his return home. While indifferent to Tortus's fate, he fiercely protected his comrades as remnants of his former self. This instinct occasionally extended to helping others, such as training Shea's clan for self-defense or rescuing his teacher Aiko Hatayama, often framed as pragmatic necessity. His journey involved confronting former classmates manipulated by Ehit, including killing Hiyama and Shimizu when they threatened his companions, actions that instilled fear in those who knew his past.
OVA episodes depicted facets beyond survival. He undertook adventures with his adoptive daughter Myu, showing unexpected paternal affection. He reluctantly participated in lighthearted harem antics like hot spring visits, maintaining his typically blunt and exasperated demeanor, highlighting his capacity for connection beneath his hardened exterior.
After defeating Ehit using metamorphosis magic, Hajime regained his original hair and eye color but retained his prosthetic limbs, disguising them to appear natural. He successfully returned to Japan with his companions. Back on Earth, his ruthlessness diminished, though he remained fiercely protective, intervening decisively against threats to his family, such as bullies targeting Shizuku's dojo or individuals harassing his loved ones. He continued to prioritize his close relationships while navigating life with his expanded family unit.
