"Ultimate Teacher" is an Action/Comedy Anime OVA from 1988, directed by Toyoo Ashida. This anime runs for nearly one hour.
Basic plot: Ganpachi Chabane, also called "Ultimate Teacher", is the new teacher sent to a run down school called Emperor High School. There he even makes the delinquent students to get prepared to the real world. The students just don't want to get ruined by Ganpachi, so their sweet, young boss named Hinako Shiratori (a high school girl) takes up a battle against the evil Ganpachi. But soon Hinako gets to learn that Ganpachi is a result of some genetic experiments...
This anime has to be the most hilarious funny anime I've seen by director Toyoo Ashida so far, also known for "Vampire Hunter D" (1985) and "Fist of the North Star" (1986). Several of the fight scenes are just so weird, you just can't take this film seriously. This is an action/comedy/anime after all. But, let's not turn away from the fact this anime even has a few scenes of fan-service.
However, the version I saw right back in 2011 was the original Japanese version, in which the credits are in Japanese.
Becaust of the fun in general throughout this anime, my overall rating has to be 8/10.
