Chizuru Maru

Chizuru Maru stands as one of the most powerful first-years in Black Dog Dormitory, serving as the self-appointed leader of the rowdy trio known as the 'Three Idiots,' alongside Tosa and Kohitsuji. He regards Romio Inuzuka as his ultimate rival and rarely misses a chance to stir up trouble with the White Cat Dormitory. Beneath his rough-and-tumble exterior, however, lies a surprisingly meticulous side — an almost obsessive dedication to hygiene and healthy living, paired with an unwavering sense of loyalty to those he calls his own. As the story unfolds, Chizuru becomes one of the first to uncover the protagonist's closely guarded secret, ultimately proving himself a steadfast and dependable ally.
