GTO: Great Teacher Onizuka volume 20

A new semester, a new position, a brand-spanking-new white suit! Yes, Onizuka's life is looking up… right up the skirt of the new head master, Ms. Daimon, who has been directed to clean house. When she institutes a system to reward good teachers and punish the bad, Onizuka feels the pain. The only way to save his job is to bring a dropout back to school, but the only available dropout is the son of a scary, scary man!
