Kudo, a lizard beastfallen enrolled in the Royal Wenias School of Magic’s special training program, bears scales that shift hue with his emotions, rendering deception impossible. Driven by a staunch sense of justice and unwavering adherence to law, his initially gruff exterior masks a fiercely protective nature. He prioritizes allies’ safety through defensive spells and physical interventions, revealing deep loyalty beneath his brusque demeanor.

A master of defensive and restorative magic, his signature spell Cordia accelerates healing, mending shattered bones within moments when augmented by external magic. Yet his effectiveness wanes when overtaxed, as he often drains his reserves unnoticed—a flaw exploited during critical missions. His lizard physiology allows severed limbs to regrow; he strategically sacrifices his tail to mislead foes or fuel spells.

As the Academy’s sole beastfallen student, his presence highlights tensions between humans, witches, and beastfallen. Through pivotal battles like repelling the Church’s assault on Zero’s village, he evolves from a guarded outsider to a trusted comrade. His ingenuity shines in co-designing traps and combat strategies, cementing his role in communal defense.

Post-graduation, he joins the Forbidden Library alongside Saybil and Holt, researching Remnants of Disaster to counter threats from the Church and other adversaries. His potential mastery of the Grimoire of Zero’s advanced healing arts hints at a future as a legendary physician or immortal sorcerer. His journey embodies loyalty, resilience, and the balance between his beastfallen instincts and his duty as a protector in a magically divided world.
