An old woman with the appearance of a young girl, Choushou is an charge of the Hyakukeitō, a set of 5 legendary Chinese jian made of jewels supposedly made by Cao Cao in ancient China. All five were embedded in a large boulder on Choushou's property and sealed with chi, making it impossible to remove. Totaku was the first person to train under her to obtain the Hyakuhekitou, then Kanu, Ryomou, and Hakufu, with Hakufu being the last one to seek training from her. Totaku went berserk in a blind sight of rage after Choushou lectured him about being weak.
