Three months have passed since Iori Kitahara moved into the apartment above Grand Blue, his uncle’s scuba diving shop, and joined his university’s Diving Club. Since then, he and the other members have spent their days drinking and goofing off without a care. But when Iori’s sister, Shiori, catches wind of his wild lifestyle, she steps in to drag him back home so he can take over the family inn. After trying her hardest, Shiori reluctantly backs off when she realizes how much Iori has come to love Grand Blue and his friends. Left to their own devices, Iori and the Diving Club keep throwing outrageous parties and stumbling into one ridiculous situation after another-yet somehow, between all the chaos, they still find time to sharpen their scuba diving skills.
