Grand Blue Dreaming - S03

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's spent his days drinking and goofing off with the other members. But when Iori's sister, Shiori, catches wind of his wild antics, she steps in to drag him back home-determined to make him take over their family's inn. Though she tries her hardest, Shiori eventually backs off after seeing how much Iori has come to love Grand Blue and his friends. Meanwhile, Iori and the Diving Club keep living it up, stumbling into one ridiculous mess after another-yet somehow, they still manage to sharpen their scuba diving skills along the way.
