Kan'u Unchou 関羽雲長

Believed to be the most feared and powerful Toushi around, she even carries the nearly invincible Blue Dragon Crescent Blade from her predecessor as well as the legendary sword Kusanagi; she also has overwhelming chi. She believes her destiny is to die protecting Ryuubi. It is believed by many characters that Ryomou will one day kill her. 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 Adaptation", it is not present in the original JPN manga).
