A strong fighter with bluish-green hair styled in bunches, Ryofu has had sexual relations with guys and girls, notably Saji and Chinkyuu. In the manga, she has a love-hate relationship with Saji, who she claims once raped her (Saji only half-denies this, claiming that she was not raped because she enjoyed it). She is afflicted with a terminal illness that would kill her before adulthood, she is manipulated by Saji into attacking Toutaku. When she found out that Chinkyuu was raped, she went in search of revenge as her last living act. She was found by Kakouen, and the two fought each other. Kakouen's skill added with Ryofu's failing health was enough for Ryofu to be defeated. She was saved from Kakouen's killing blow by Chinkyuu. Realizing that she was moments away from dying, Ryofu and Chinkyuu then committed a double suicide, dying happily together as their predecessors did 1800 years before.
