Ryubi's best friend and an avid snack-lover who is a first-year student at Seito Academy.
Although quite weak and only a C-ranked fighter, history states that she will one day become so powerful that legends will tell of her matching ten-thousand men (just like Zhang Fei himself), which makes her well-known around town.
She has already performed such a feat, although on a much smaller scale, when Kyosho first assaulted Seito to search for Ryubi. Kakouen almost killed her during their fight, but she was luckily saved by Choun. She is currently out of action, recovering from the serious injuries suffered in the fight against Kakouen, with Ryubi staying by her side.
Her anime incarnation portrays her as a bossy character, and is frustrated that Ryubi is not the powerful fighter she is meant to be as Seito's leader.
Despite that, she is still best friends with Ryubi and Kanu. She is strong enough to throw Kanu several stories into the air (probably representing Zhang Fei's roar at Changban when the Shu forces were retreating from Cao Cao).
At the end of the series, she is seen in a restaurant with Kochu, hinting that the two could be a couple.
