A strong bisexual fighter with a very promiscuous personality and a habit for dressing in skimpy outfits. She was very skilled at making chi blasts, and was in love with both Saji and her best friend Chinkyu. She had 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). Despite trying her best to escape her destiny, she ended up causing it anyway. Afflicted with a deadly illness that would kill her before adulthood, she ended up being manipulated by Saji into causing Totaku's death. When she found out that Chinkyu 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 Chinkyu. Realizing that she was moments away from dying, Ryofu and Chinkyu then committed a double suicide, dying happily together as their predecessors did 1800 years before.
In the anime adaptation, Ryofu is portrayed as more of a thuggish brute, unlike her manga counterpart who is a skilled tactician. She did not plan on acquiring the Gyokuji or betraying Totaku, and was more easily manipulated by Saji. She is more emotional as well and more promiscuous and cruel, shown when she molested Ryomou as opposed to simply teasing her in the manga. She is just as powerful, however, as her manga counterpart. In the end, she died fulfilling her fate by using a chi blast to commit suicide with Totaku (Chinkyu died earlier in the series and so did not join her). The second season recalls a different scene, however, with Ryofu tackling him off a cliff, but also accounts it as double suicide. Whether that is meant literally and that the past events have been changed metaphorically where in which it was Ryomou's perspective or the aura-sensed perspective of others that has changed is not known.
Though she is only shown in occasional flashbacks in Dragon Destiny, Ryofu appears again as a living character at the beginning of Great Guardians, initially fighting and brutally beating Kanu before being stopped by a sudden bolt of lightning from the sky. This incarnation of Ryofu, whose reappearance causes great turmoil to the still-living fighters, is mostly the opposite of her former one, being shy and introverted and pretty much devoid of malice or any flirtitous tendency. Initially amnesiac, after being taken care of by Ryomou, she went to Rakuyo in search of clues regarding her past, there being abducted by Ouin and brainwashed by the real Genpou Saji, thus gaining a more cheerful but visibily false persona. From there on, she played with Ouin so as to fill Ryomou with jealousy until Saji herself was discovered, when she was turned into a frenzied berserk as a mean of halting Hakufu and her companions. The last episodes also reveal that, in fact, this Ryofu is actually much like a living dead, a spirit partially resurrected by Saji that, after regaining her senses, fades again from this world, bidding farewell to Ryomou. Still, one last line from her can be heard when Saji is praying at her tomb ("Thank you").
