Grand Blue Season 2

Three months after moving to Izu, Iori Kitahara has become far more attached to life above the Grand Blue diving shop and to his club companions than he ever expected. He is finally gaining genuine experience underwater, although his university life on land remains packed with parties, competitions, and spectacularly poor decisions that can make diving seem like the calmest part of his week.

The balance is disrupted when his younger sister Shiori arrives determined to bring him home so he can eventually take responsibility for the family inn. Seeing his new life firsthand, however, forces her to recognize how deeply he has grown attached to his friends and the sea. Between family pressure and his evolving relationships with Chisa, Kouhei, and the others, Iori tries to prove that his time in Izu is more than temporary chaos, even if everyone around him seems determined to make it look exactly like that.
