Grand Blue Season 3 has officially been confirmed, and fans couldn’t be more excited. After the long-awaited return of Season 2 in 2025, the finale delivered an announcement many were hoping for: Iori and his chaotic group of friends will be back for another season. This time, the story takes a new direction as the cast travels overseas for the first time. If you want updates on Grand Blue Season 3, the manga arcs it will cover, where you can watch it, and when it might release, here’s everything you need to know.
Grand Blue Season 3 Manga
Grand Blue Season 3 will adapt some of the most anticipated parts of Kenji Inoue and Kimitake Yoshioka’s manga. With more than 24 volumes published in Japan, the series still has plenty of material for future seasons.
Season 1 adapted up to around chapter 21, and Season 2 covered material up to the early 40s. Season 3 begins after the island camp fallout and moves into the Palau Arc (roughly chapters 50–57), one of the most popular sections in the manga. The season may also touch on the Okinawa 2 Arc (chapters 61–69), bringing new locations, bigger diving moments, and the same chaotic humor fans expect from the series.
For viewers who want to get ahead of the anime, the manga remains the best way to follow Iori’s story past Season 2.
Grand Blue Season 3 Anime
The third season was officially announced on September 22, 2025, right after the broadcast of Season 2 Episode 12. The announcement visual confirmed that the new season will take Iori and his friends to Palau, marking the first time the anime takes place outside Japan. Palau’s coral reefs and underwater life make it a perfect setting for Grand Blue’s diving-focused comedy.
Studios Zero-G and Liber are returning to animate the new season. Familiar cast members such as Yuma Uchida (Iori), Chika Anzai (Chisa), and Ryohei Kimura (Kohei) will reprise their roles. New characters introduced in Season 2—like Shiori Kitahara and Sakurako Busujima—are also expected to return.
Most of the main staff is coming back, including director and scriptwriter Shinji Takamatsu and character designer Hideoki Kusama. With the same creative team working on Season 3, fans can expect the same humor, character energy, and expressive animation style.
Where to Watch Grand Blue Season 3
An official streaming platform has not yet been announced for Grand Blue Season 3. However, based on past releases, the new season may stream on:
- Amazon Prime Video
- Crunchyroll
- HiDive
- Netflix (region-dependent)
Season 2 aired on Tokyo MX, BS11, and MBS, so similar broadcast partners are likely for Season 3. Fans should follow the official website and X account for the earliest updates.

Grand Blue Season 3 Anime Release Date
As of now, there is no official release date for Grand Blue Season 3. The announcement only confirmed that production has begun. Anime productions typically take 18–24 months from early development to final broadcast, and Season 3 appears to be starting fresh.
Here’s the timeline so far:
- Season 2 was announced in September 2024
- It aired in July 2025
That faster turnaround happened because Season 2 was already far into production before the public reveal. Season 3, however, features a brand-new overseas setting like Palau, which requires additional background work and animation planning.
Considering average production schedules, the most realistic estimate for the Grand Blue Season 3 release date is mid-2027 to early-2028. This gives the studios time for pre-production, animation, voice recording, and marketing.
Fans should watch for key visuals, trailers, or broadcast updates from official channels.
Final Thoughts
Grand Blue Season 3 is shaping up to be one of the most exciting seasons yet. With the story moving to Palau, expanding its cast, and adapting fan-favorite manga arcs, there’s plenty to look forward to. While the release date is still unknown, the confirmation alone has energized fans across the community.
If you enjoy outrageous comedy, chaotic friendships, and surprisingly heartfelt moments, Grand Blue Season 3 will definitely be worth the wait. Stay tuned for more updates as Iori and the Peek a Boo crew prepare for their biggest adventure so far.
