Kurenai Tsubasa (Japanese).
First Appearance: Manga volume 10
History: Tsubasa is a crossdresser. His
apprearance is that of a cute (cuter to the guys of Furinkan High than
even female Ranma!) girl. He is known for dressing up (besides as a
girl) as trees, garbage cans and soda machines, among other things.
Though Tsubasa initially attacks Ranma at first, it is clear that he
really can't fight all that well. But that's okay. ^_^
