ぐらんぶる

Iori Kitahara moves to a coastal town to start university and live above his uncle's dive shop, Grand Blue. Instead of the breezy campus life he imagined, he walks into a clubroom full of near-naked upperclassmen chugging pure alcohol. Dragged into the Peek-a-Boo diving club alongside the equally reluctant Kouhei Imamura, Iori ricochets between drunken chaos and elaborate pranks, and the rare trips the older members make underwater turn into genuinely stunning dives that keep pulling him back.
