The island of the everlasting summer, Seiran Island.

Junnosuke Tachibana, whose family home was on this island, returned to it with his sister, Asane Tachibana, after the death of their parents.

However, Seiran Island has become a place of madness due to the implementation of the “Perverted Law,” a law designed to combat population decline. This law permits and even encourages lewd sex acts everywhere on the island, and refusing to engage in “reproductive activities” is punished almost as severely as a crime.

Junnosuke, a proud virgin and staunch defender of virginity, questions the legitimacy of this law. Determined to protect both his and his beloved sister’s purity, he forms the anti-copulation front NLNS (No Love No Sex) and sets out to destroy the Perveted Law once and for all.

“I’ll… destroy the Perverted Law!”

GTO

Also known as GTO: Great Teacher Onizuka.

Studio: Studio Pierrot , Discotek , Aniplex
Status: Finished
Genres: Comedy , Drama , Slice of Life

Onizuka is a reformed biker gang leader who has his sights set on an honorable new ambition: to become the world's greatest teacher... for the purpose of meeting sexy high school girls. Okay, so he's mostly reformed.

However, strict administrators and a class of ruthless delinquents stand between Onizuka and his goal and they will use any means, however illegal or low, to drive the new teacher away. Perfect, because Onizuka's methods won't be found in any teaching manual; he cares about the difference between legal and illegal activities about as much as he cares for the age difference between himself and a high school girl.

So get ready for math that doesn't add up, language you'd be slapped for using, and biology that would make a grown man blush... unless of course, you're the Great Teacher Onizuka.

Note: Episode 1 has an airtime of 48 minutes.
