Non-Yaoi Delinquent manga wanted

beelzebub

oresama teacher

Seen the Anime:)

He is a High School Girl (but try reading it on other site)
Atashi No Banbi
Lookism (main character isn't a delinquent but everyone around him is lol)

Lookism was pretty good, I tried to find others like it. Haven't read the others yet, looking forward to it, though! Thanks:)

Cromartie high school is really funny, mob psycho 100 has some delinquent undertones, it's getting an anime soon so look out for it (I really recommend the manga). Have you watched the movie akira? It's really well written, a bit lengthy, but it's amazing! ٩(๑❛ᴗ❛๑)۶
