Grand Blue

Synopsis

The members of Peek a Boo meet up at Miyakojima to go deep-sea diving. Iori, who never finished his exam due to sickness, is forced to stay in shallower waters while being teased about it by Kohei. As the licensed group goes diving, Chisa decides to stay on the boat to comfort Iori, who turns out to be suffering from seasickness. He then tells Chisa that despite missing the license, he had fun diving and would love to come back again. That night, after news that the group has been banned from their chosen restaurant, Shinji and Ryujiro announce that they will hold their own "Otori" in the hotel, where everyone will drink from a giant pot of mixed alcohol. Everyone begins by pouring in Spirytus, as Iori and Kohei try to find a way out of drinking such a high level of alcohol, but soon give in. Aina later takes a trip with a mostly-naked Iori to get more booze for the party, and rants about his lack of clothing upon returning. Azusa offers Aina a drink, but she accidentally picks the heavily-alcoholic beverage, and her personality completely flips as she scares Iori and Kohei into fleeing from the hotel. Iori and Kohei reflect on their time in the diving club as Aina quickly tracks them down.
