A third-year student at Seito Academy and was an A-Rang fighter however, after the events of the battle against Soso Motoku and the start of the attack of fighters from the Kansai region under the leadership of Himiko Kan'u became even stronger and is a S-Rang fighter now thus making her the strongest fighter of Kanto so far. She wears a variation of her school's uniform, where her shirt only extends to her midriff section, and wears baggy socks, which are common aspects of the kogal and ganguro styles among Japanese schoolgirls. Believed to be the most feared and powerful fighter in the Kanto region, she carries the nearly invincible Blue Dragon Crescent Blade from her predecessor as well as the legendary sword Kusanagi, and also has an overwhelming amount of chi. She believes her destiny is to die protecting Ryuubi. It is believed by many characters that Ryomou will one day kill her. She is presumed to be an old friend of Kakouton and Kakuka. Despite this, however, she seems to have taken an interest in Koukin (this happens only in the English manga, where it is not present in the original manga). She is eventually forced to side with Sousou and plan an attack on Nanyo in order to protect Ryubi from Kyosho's fighters, who would certainly be after her. When she surrenders, she is treated as a prisoner; she is handcuffed, beaten, and stripped of her clothing. When Ryubi submits the Gyokuji for Kanu's release, Kanu refuses to accept the offer and stays as a prisoner under her own will. Sousou respects Kanu's wishes and orders the Gyokuji to be returned to Seito. Kanu is able to break free from her handcuffs, clearly holding back while she was captive. She is now treated more fairly while being kept under Sousou's orders.
