GREAT TEACHER ONIZUKA (Gureto Ticha Onizuka), by Tohru Fujisawa. First published in 1997 and first published in North America in 2002.
PLOT:
Eikichi Onizuka is tired of being just another aimless punk. He's determined to make something of himself, and he's convinced that he needs to be a teacher. Not just any teacher, though - he wants to be the greatest high school teacher ever, the sort who whips kids into shape and maybe scores a bit of action on the side! He manages to barely graduate his certification program, but his first assignment may be his greatest challenge. He'll have to use all his cunning and street smarts to survive not only a class full of delinquents determined to break him down as well as administrators skeptical of his ability to succeed at life, much less teaching.
