From Tokyopop:
Before Ekichi Onizuka would become the "Greatest Teacher in the World," he and Ryuji Danma were members of the infamous biker gang, Oni Baku. When they weren't out riding around and getting into trouble, this duo could be found in school. Doing what you ask? Picking up young women of course!

Before Eikichi Onizuka became a legend, before Onibaku, before he became GTO, he was just a normal junior high school delinquent. Getting into fights with his seniors, trying to pick up girls and just hanging out with his friends. Bad Company is a compilation of many short stories, linked together with the characters of Eikichi, Ryuji and their school buds. Such stories involve the origins of Eikichi`s bike, which we see frequently in GTO, the first meeting with the Midnight Angel and many other.

A full color gourmet comedy that features a cute new character every week!

GTO: Paradise Lost is a sequel to GTO and Onizuka is now 24 years old as well.

Rose Hip Rose is a manga about a teenage girl who fights crime. While the setup doesn't sound so great, it gets better as the manga progresses. The series' major strong point is the art. Along the way, she ends up having a showdown with a major criminal named The Goat. However, it seems that The Goat doesn't seem to like being caught. Be wary, though, the series is very violent.

The art and story are by Fujisawa Tohru, author of GTO and Bad Company. The art is quite nice, but somewhat different from GTO's. If you like violence, gore, Fujisawa, or cacti, Rose Hip Rose is the manga for you. Oh yeah, did I mention it was violent?
