Sukeban Boy 2006

Directed by Noboru Iguchi

A raucous teen boy with a feminine face is teased everywhere, so his odd biker father dresses him as a girl and sends him to an all-girl school. The lad introduces himself as Sukeban, and a classmate, Michiko, takes him to after-school activities. Lessons on humility turn violent when a masked hatchet-wielding woman turns up. Jealousy, syringes of hormones, bare breasts, a blood bath, and more figure in the resolution.
