To attend a university, Iori Kitahara moves into his uncle’s diving shop, “Grand Blue”, in Izu. The sound of the waves, the blazing sun, and living with his beautiful and cute cousins, Nanaka and Chisa Kotegawa, raise Iori’s expectations for his new university life. But what awaits Iori is a group of muscular guys who, when it comes to rock-paper-scissors, only know how to play “yakyuken” (strip rock-paper-scissors)…
Iori is targeted by the university’s diving club, “Peek a Boo,” soon after entering the university. Lured by Shinji Tokita, the president of the diving club, and Ryujiro Kotobuki, a third-year student, Iori unknowingly ends up joining a binge party as a member of “Peek a Boo”. Kohei Imamura, a good-looking but hopeless otaku guy also joins the club, and Iori’s university life unfolds in a way he never imagined.
Set against the backdrop of Izu`s beautiful seaside, the anime features the wild energy of university guys who love drinking, playing yakyuken and stripping naked. (it’s a far cry from a stylish student life) The story highlights the contrast between their rowdy antics and sincere attitude toward diving. This must-laugh campus comedy is still going on. The production of Season 3 has been decided!
