Koudai Chinkyuu 陳宮公台

Ryofu's childhood friend and lesbian lover, and a C-rank fighter with great potential. While Ryofu was battling Totaku, Chinkyu knocked out Kaku to prevent her from interfering. Kaku got her revenge when she caught Chinkyu stealing the Gyokuji and got Rikaku to rape her. When Chinkyu recovered from her injuries, she saves Ryofu from being killed by Myosai. However, she realizes that Ryofu is moments away from dying due to her illness. Since she was loyal and in love with Ryofu, Chinkyu decides to stay by her friend's side and commits suicide with her instead of surrendering to Sousou. In the anime, she dies in the hospital from injuries inflicted when she was raped. She also tried to steal the Gyokuji on her own accord, rather than being ordered to do so by Ryofu, and wanted to present it to Ryofu as a gift before she died.
