Meet Eikichi Onizuka, a 22-year-old college karate champ and ex-biker. He's crude, foul-mouthed, and has a hair-trigger temper. His goal: to be the Greatest High School Teacher in the World!
In GTO Volume 7: Showbiz, Onizuka gets into a financial mess when he embezzles school finances. His students come to his aid and uncover Miyabi's scheme, but Onizuka decides against a counter attack. Instead, he puts his pride and career on the line and announces that he will personally pay for a class trip to Okinawa in order to make up for his mistake.
