Narumi Katou

Narumi Katou is a formidable practitioner of Xingyi Quan whose life takes an unexpected turn due to a rare condition known as 'ZONAPHA Syndrome'—a mysterious illness that forces him to make others laugh in order to breathe. This peculiar affliction draws him into a fateful bond with Masaru Saiga. After sustaining near-fatal wounds in battle, he drinks the legendary Water of Life and is reborn as 'Shirogane', a warrior destined to combat the threat of automata. Fiercely protective and driven by an unshakeable sense of justice, Narumi briefly hardens under the weight of relentless conflict, yet never loses sight of his core mission: to shield the children around him. He stands as the beating heart of hope throughout the entire story.
