Doppo Kunikida

Doppo Kunikida stands as an indispensable pillar of the Armed Detective Agency, having previously built his career as a mathematics teacher. He carries a personal notebook at all times — filled with his cherished ideals — and operates on a schedule so precise it borders on clockwork. Though his erratic partner Osamu Dazai perpetually tests his patience, Kunikida channels his exceptional organizational skills and ironclad sense of responsibility into safeguarding the Agency's mission. It comes as no surprise that he is unanimously considered the sole worthy successor to the Agency's leadership.
