Grand Blue Dreaming returned for its third season on July 7, streaming on Crunchyroll after a seven-year gap since Season 2. The new season sends Iori and the rest of the diving club crew outside Japan for the first time, relocating the story to Palau for a change of scenery that fans have been anticipating since the wait began.
What's New in Season 3
Season 3 picks up with Iori's cousin enlisting him to help run a new dive shop in Palau, moving the show's setting outside Japan for the first time in the series' history. The 12-episode season is produced by Zero-G and Saber Works, with Shinji Takamatsu returning as director to keep the show's signature blend of diving culture and drunken chaos intact in a new location. Voice actor M.A.O. was announced as joining the cast for the new season, adding to the returning lineup of characters fans have followed since the manga's early chapters.
The Long Wait Between Seasons
Grand Blue Dreaming's second season aired in 2019, meaning fans waited roughly seven years for a follow-up. That gap made Season 3 one of the more anticipated returns in the current anime season, with a teaser trailer released back in March generating significant buzz well ahead of the July premiere. The main opening theme for the season, "Natsuko," comes from FUNKY MONKEY BΛBY'S, while MAMESHiBA NO TAiGUN performs the ending theme "Hadaka no Mermaid."
Where to Watch
Grand Blue Dreaming Season 3 is streaming exclusively on Crunchyroll, which has handled the series' international release throughout its run. New episodes are releasing weekly, following the platform's standard simulcast schedule for the 12-episode season.
Conclusion
After seven years away, Grand Blue Dreaming's return delivers exactly what longtime fans wanted: the same chaotic diving-club energy, just with a new backdrop in Palau. With a full 12-episode season and the original creative team back at the helm, Season 3 looks positioned to close out one of anime comedy's longest-running gaps between seasons on a high note.
