When you think about the best college comedy anime, there is one anime that pops up in the mind of every anime fan: Grand Blue. This was likely the most popular seinen anime of the year, and it left a hole in fans’ hearts 7 years ago when the anime ended. However, Grand Blue is finally back with its second season, which will be airing in July 2025.
In this article, we will reveal everything you need to know about the release of the second season of Grand Blue, with information on its cast and even a recap of the previous season. If you haven’t watched Grand Blue yet, we urge you to watch the first season before the anime airs.
Grand Blue Season 2 Release Date

The official visual of the second season of Grand Blue was released on the 7th of March. The visual featured all the members of the Peek a Boo club raising their beer mugs in a celebratory toast, probably because the anime finally got renewed.
The PV for the second season was also released shortly, on the 21st of March. The trailer teased a bit of the contents of the second season, assuring us that the Peek a Boo club is going to be just as barbaric as ever.

Grand Blue Season 1 Recap
If you’re worried that you’ve forgotten most of the happenings in season 1 of the anime, fret not, because being the episodic anime that it is, not many moments in the anime had a direct influence on the progression of the story. The anime started out with Kitahara Iori starting college in a town next to the seaside, where he gets forced to join a diving club. This club, however, did more drinking and partying than diving, so Iori blended in pretty well even though he was forced to join.
Iori now lives with childhood friends, Kotegawa Chisa and Kotegawa Nana, are also a part of the Peek a Boo diving club. The dynamic between the three is interesting because Iori seems somewhat interested in Chisa (he also seems to be interested in many other girls, but let’s ignore that for now). Meanwhile, Chisa’s sister, who is older than her by a few years, has a sister complex.
Chisa was initially interested in Iori but got completely turned off after seeing how Iori had grown up to become an absolute scumbag (for context, Iori just moved back into the town in which he grew up in with Chisa, Nana and many others). Iori also befriended a hardcore otaku named Imamura Kouhei, with whom he frequently has fights. Besides all the nudity, vulgarity, and parties, this anime does have a major theme: diving.
Iori doesn’t know how to swim, but still decided to try diving because he was drawn to the beauty of what lies under the sea. Unfortunately for him, the season ended with Iori failing his diving test, making him the only member in the club to be ineligible to dive without supervision. Iori was pretty bummed out about this, but bounced back pretty quick thanks to Chisa’s encouragement.
Another aspect of the anime that’s worth mentioning is Iori’s relationship with a character named Hamaoka Azusa, who is also a member of the Peek a Boo club. Due to a few misunderstandings, Azusa thought Iori had a crush on Kouhei, which made her feel close to him, as she had always wanted a bisexual friend. Iori’s inability to clear this misunderstanding has paved the way for many gags in the anime.
