Kudō, a lizardman-like Beastfallen with piercing blue eyes and a smooth, hairless hide, stands apart from his kin through diminished physical prowess yet compensates with burgeoning magical aptitude. Though lacking the brute force typical of his race, he channels his focus into protection magic, steadily cultivating expertise in healing arts drawn from the Grimoire of Zero’s protective incantations—a path that may lead him to become a long-lived sorcerer-physician.

His brusque, impatient exterior masks a fiercely loyal core. While quick to bristle at surface interactions, he reveals unwavering devotion to allies, risking himself to shield them from threats like witch hunters from the Church’s remnants. This protective drive persists despite past torments: captured by the mercenary Tyrant, he endured shattered hands and torturous experimentation, trauma that lingers but never erodes his resolve.

As a Royal Academy of Magic student, he collaborates with peers on a diplomatic mission to mediate peace between humans and witches in a fractured village. Post-graduation, he joins the Forbidden Library’s research on Remnants of Disaster, channeling his resilience into scholarly pursuits. His history remains shrouded in mystery—no records detail his origins or lineage—yet his evolution thrives through camaraderie and conflict. Through alliances and clashes, he sharpens both spellcraft and loyalty, emerging as a linchpin in efforts to mend a world fractured by prejudice and cataclysm.
