With a history of leading a motorcycle gang and getting bad grades in school, why would 22 year old Onizuka ever want to become a teacher? Is it to educate young minds or spread the joy of education? Sure, if it involves being able to look up high school girls' skirts! Watch as this would-be educator uses his own life lessons and unconstituted methods as a means to control a delinquent class of students -- students who certainly aren't as happy to have him as a teacher as he is happy to be teaching...
Because of similar main characters both series reminded me of each other. Both are delinquents, both are incredibly strong and incredibly dumb, yet both have something in them that can influence others. So, if you liked the male lead in one series, you might want to give the other series a go.
