I've been reading manga and I've just read and amazing one, The Breaker. It's about this wimpy kid who after seeing his (gorgeous and perverted) substitute teacher do some unbelievable moves begs him to teach him to fight. There's blood, hot guys and gals, and awesome fights. I mean there are like sixty or fifty something chapters and I read them ALL yesterday I loved it so much. If you're a guy it's the perfect shounen manga, if you're a girl just ignore the fanservice in the first few chapters. I'd highly recommend reading it.
Here's two of the hardcore covers (the one on the left is the teacher and the one of the right is the student):
