An anime OVA series from Studio Pierrot, known in Japanese as Koko wa Greenwood. Follows a group of high school-aged boys through their lives in their boarding school dorm: Ryokurin Hall, better known as Greenwood.

Hasukawa Kazuya is just an ordinary guy, except for that his first crush just married his older brother, who raised him after their parents' death. So he moves into Greenwood -- only to find that it's the craziest dorm on campus, full of odd characters: video game otaku, religious fanatics, gay lover roommates, and Kazuya's own roommate, who turns out to be intersexed.

Naturally, things just get weirder -- with ghosts, girl gangs, and romance gone gonzo.
