Onidere (Manga)

Tadashi is in his second year of junior high school and is a member of the handicraft club and loves nothing more than knitting. Unfortunately he's in secret relationship with Saya, the member of a notorious all-girl gang, who says she will kill him and herself if anyone is to find out about it.

All the bitchslaping and stuff is funny. Sometimes it has some really weird and nonsensical scenes but yeah, otherwise an worthwhile manga.
