Grand Blue Season 4

Iori's Okinawa getaway refuses to calm down. After Sakurako learns about his lottery win, she decides to close the distance between them, while Aina is just as determined not to surrender the field. With Chisa caught in the middle, a trip that was already full of bad ideas turns into an increasingly chaotic contest of jealousy, misunderstandings, and reckless schemes.

Back among his friends, Iori still has diving, parties, and the usual absurd disasters to deal with, but the feelings gathering around him are becoming harder to laugh away. As Sakurako presses forward and Aina fights back, every attempt to keep his relationships simple only gives the romantic battle another chance to explode.
