ぐらんぶる

Iori Kitahara moves to a seaside town on the Izu Peninsula to start college, lodging above his uncle's diving shop, Grand Blue. He expects a calm new life and instead gets dragged into the Peek-a-Boo diving club, a pack of college guys who spend far more time drinking and stripping than actually diving. Caught up alongside his otaku friend Kohei, Iori keeps trying to reach the actual scuba lessons while the club's relentless drinking games derail him at every turn.
