Asuka Hybrid

Asuka is a boy that recently switched schools. He was accidentally put in the female dorms. While he was outside Asuka helped someone who turned out to be a witch and as thanks she offered him one wish. He said he had just been put in a women's dorm even though he's a boy. She misinterprets this, turns his body into a girl, and runs away before he can react. He must now attend school as a girl and look for the witch in his spare time so she can change him back.
