Im looking for school life mangas that's about delinquents / bullies / blackmail and whatnot...

I prefer if they are seinen/josei and mature/adultly (no hentai) themed.

Stuff like Onani Master Kurosawa for example.

Thanks in advance

Blue Spring
The grittiest school life manga in English.

Holyland - some loser guy decide that enough is enough and fight back. It leans toward martial art manga in the end but still a great read though. It has a sense of realism in it

Angel Densetsu - One of the whackiest school delinquent manga out there, it's filled with coincidence and misunderstanding that keep on blown out of proportion

Worst - This manga shouldn't even be considered as a school delinquent manga cuz none of the students looked like a student. Hell, they all look like some kinda middle age yakuza group the way i see it. But still though, it is funny and action pack

Check em out
