The governor of Dazaifu and commander of the Kyūshū division of the Red Army, Shidou is the Red King's cousin and closest confidant. While generally warm and genial, Shidou does not flinch from the grizzlier duties of leadership - he is a calculating and ruthless general who is said to leave mountains of corpses behind him on the battlefield. Shidou is the first character to realize the full implications of Sarasa and Shuri's relationship, but he is killed before he can speak of it.
