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.
