Visual Novel Version Bach�'s cousin. A new character in the sequel, Shin Koihime Mus�. Despite being younger than Bach�, she has no issues being around men. In fact she often teases Bach� about the latter's issues with men, sometimes by putting her into embarrassing situations, like bringing her to see Kazuto while he's bathing in a river causing Bach� to freak out. She also likes Kazuto, and is aggressive in pursuing him, going as far as to lead him out to a forest (on the pretense that Bach� was kidnapped), knock him unconscious, and have her way with him. Anime Version Batai first appears in the 11th episode of Shin Koihime Mus� to train under her cousin Bach� and made friends with Riri at Touka village. Due to Bach� harsh training methods, Batai gets her revenge on her by tricking her to drink a giant gourd of water and not allowing her to use the bathroom by sundown or faced being called a bed wetter. In Otome Tairan, Batai snuck-out so she could go on an adventure with Chouhi and Ryuubi. She later meets Gien, who she develops a rivalry with. (wikipedia.org)
