Ép. 1: Iori arrive à Grand Blue pour ses études universitaires et se retrouve entraîné dans les délires du club de plongée Peek a Boo.

Iori Kitahara heads to the shop Grand Blue to meet with his extended family and start his new college life. However, he is shocked to discover the shop overtaken by several rowdy, drunken, naked men. As Iori runs away, two of the men from the diving club chase after him, eventually catching him and dragging him back to the shop. While trying to find someone to take the scene seriously, Iori gets swept up in the antics of the club, getting drunk and stripped of all clothing except his boxers. The next day, Iori and the other two men wake up just outside of Izu University for his orientation, but he has no time to change. After a brief encounter with Kohei Imamura, Iori tries to find someone to give him spare clothes, but he sounds like a pervert and is chased around campus by police. Eventually, Iori is initiated into the "Peek a Boo" Diving Club by the two men from earlier: Shinji Tokita and Ryujiro Kotobuki. Iori tricks Kohei into joining the club with him, and the two freshmen are pressed into a drinking contest where even the "water" is a large glass of vodka. (Source: Wikipedia)
