Fans Endured 7 Years for Season 2 — Grand Blue Dreaming Season 3 Is Already Announced
Grand Blue is splashing back with season 3—announced in the most on-brand way possible: scrawled on a buttcheek. A cheeky reveal for a series that never misses a chance to go overboard.
Good news for anyone who just powered through Grand Blue Dreaming season 2: we are not doing another seven-year drought. Season 3 is locked for July 2026.
Yes, that turnaround is real
The official site dropped a season 3 production notice earlier today (September 22, 2025), basically right after the season 2 finale aired. Compared to the glacial gap between season 1 wrapping in 2018 and season 2 finally arriving seven years later, this is light speed.
We are going overseas — to Palau
The next season sends the cast out of Japan for the first time, landing them in Palau. If you know this show, you are already imagining the chaos of putting Iori and the boys anywhere near clear water and cheap booze.
"Season 3 will be set overseas for the first time, in Palau! Will it be okay to let Iori and the others leave the country? Further information will be announced on the official website and official X!"
How big is Grand Blue right now?
Still huge. On Crunchyroll, it sits among the top-rated comedies with over 11,000 user reviews averaging 4.9 out of 5. Over on MyAnimeList, season 2 is currently in the top 100 with an 8.62 user score, even edging out season 1’s 8.44. For a series that is basically the Japanese college-town cousin of American Pie — lots of nudity jokes, a heroic amount of drinking, and a diving club that rarely dives — that kind of consistency is rare.
Production notes, and a little inside baseball
Season 2 reunited the original studio, Zero-G, with support from Liber, and it looks like that team isn’t taking a breather before rolling into season 3. Given how much manga material has been sitting there since 2014, this is the cadence fans expected years ago. Also: the announcement art? Let’s just say a butt cheek branded with a giant 3 tells you everything you need to know about the show’s maturity level, in the best way.
- Premiere window: July 2026
- New setting: Palau (first time the anime goes abroad)
- Studios on season 2: Zero-G (returning), with Liber supporting
- Timeline check: season 1 ended in 2018; season 2 landed seven years later; season 3 follows next summer
- Announcement timing: production notice posted right after the season 2 finale on September 22, 2025
- Where to watch for updates: the official site and the show’s X account
- Current scores: Crunchyroll average 4.9/5 from 11,000+ user reviews; MAL season 2 at 8.62 (top 100), season 1 at 8.44
Bottom line: Grand Blue is staying hot while the buzz is fresh. See you in Palau — bring sunscreen, and maybe some pants the cast won’t wear anyway.
