Kantai is secretly the general of the province of Baku. He is a hanjyuu that can take the form of a large bear, and he is incredibly strong, even in human form. He saves Shoukei after she ran from the soldiers who sought to arrest her after she threw a rock at Gahou's executioners. Kantai seeks to expose the corruption of Gahou, and he sends Shoukei to the intermediate village of Houkaku to provide touki weapons to the Shisui rebels. Suzu arrives there to take the weapons to Takuhou. When Kantai realizes that his allies in Shisui will be wiped out by Gahou, he sends his own forces to intervene. Shoukei accompanies him and seeks out Suzu to inform the Shisui rebels that Kantai is on their side. When Koushou insists on saving Takuhou from fire, Kantai is shamed into helping him despite his doubts. When Youko asks Kantai what reward he wants for fighting corruption, Kantai asks for pardon for his lord Koukan. After Gahou is defeated, Youko places Kantai in charge of Kei's entire army
