Mouyuu

She is the second leader of Nanban High, she is the level-headed and honorable one of the duo. She went to great lengths to try and kill Ryubi Gentoku in which had her meeting with a nude Chou'un who was managed to match Mouyu's strength and force her to retreat. However, Mouyu wouldn't be gone for long, because in a few episodes, she returns to fight Chou'un again and was trumped by her sheer power, and opted to take her own life just to be saved by Ryubi's fluctuating power which forced her to change her perspective of ruling Kanto. She would eventually shift sides and aid Seito in the destruction of Kentei's lair (within Nanban) and causing Kentei's full-fledged revival to cease.
