Bunbun Residence

"Bunbun Residence" is a surreal gag mahjong manga set in the chaotic dormitory of Kawakita University. The story follows Koji Yakamo, a meek, glasses-wearing college freshman, who becomes entangled in endless mahjong battles within the dorm. Each time, he is pitted against the mysterious and all-powerful upperclassman known as Ichijiru-senpai, a resident legend whose custom-made, absurd house rules make every match a fresh nightmare. From “100-player mahjong” to “four parents per hand,” every chapter introduces a new, often nonsensical rule that leaves Koji humiliated, outplayed, and stripped of dignity. Despite the hopeless odds, Koji keeps coming back for more — whether out of pride, curiosity, or just the magnetic madness of the dorm. Overflowing with slapstick, deadpan humor, and a deep love of mahjong chaos, Bunbun Residence is a cult comedy series from the 1990s that satirizes both university life and the obsession with house rules in Japanese mahjong culture.
