Chutatsu Shibai

The strategist of Kyosho Academy and arch-nemesis of Koumei. She is paraplegic, having lost her feet years ago while Teni went on a killing rampage, and uses a wheelchair for mobility. She also has a dragon tattoo on her right hand (in the anime, they glow whenever she uses her chi or senses a strong opponent). Teni looked up to Shibai and called her “Maria-sama (Lady Maria)”, treating her as a divine higher power. Shibai is secretly running Kyosho and is also Sousou’s lover. She is secretly manipulating Sousou towards an ill-defined goal, and shows no signs of sympathy towards her loyal fighters. For example, she did not show any remorse towards Teni after she was horribly injured by Ryomou during their battle. She was almost killed by Sousou during one of his dragon stages but was saved just in time by Kyocho.

It is later revealed by Kentei in volume 17 of the manga that Shibai’s real name is Shikyo Gifu (魏諷 子京 Gifū Shikyō?), the Japanese equivalent of Wei Fang who was a minor figure in Ancient China.
