GTO: Great Teacher Onizuka
#30 in Manga (Readables)
Great Teacher Onizuka centers on the 22-year-old Eikichi Onizuka, a former gang member turned teacher. Class 3-4 is more than willing to have him fired from the school but he foten outwits them with his remarkable yet sometimes absurd, foolish antics. However, challenges are really inevitable throughout his stay in the school - including the infuriated vice principal, old rivals from his biker days, and the way he delivers his lessons to his students.
