*Grand Blue Dreaming* is officially returning for Season 4.
[The fourth season was announced](https://animecorner.me/grand-blue-season-4/) following the conclusion of *Grand Blue Dreaming* Season 3, which aired its 12th and final episode on September 21, 2026. A new promotional visual was also released to mark the announcement.
For now, however, the confirmation is still an early one. A premiere date and other major details about Season 4 have not yet been announced.
Grand Blue Dreaming Season 4 is officially confirmed
[The announcement came immediately after the end of Season 3](https://animecorner.me/grand-blue-season-4/), giving fans confirmation that the anime will continue without another long period of uncertainty over its future.
Alongside the announcement, the anime released a new visual featuring Chisa Kotegawa, Aina Yoshiwara and Sakurako Busujima, while a photograph of Iori Kitahara appears at the center of the image.
The visual hints at the character dynamics that will carry into the next part of the story, but no detailed synopsis for Season 4 has been announced.
When will Grand Blue Dreaming Season 4 be released?
There is currently **no confirmed release date for Grand Blue Dreaming Season 4**.
The announcement confirms that another season is moving forward, but no broadcast window has been provided. That means any specific 2027 release date circulating online should be treated as speculation unless it is later confirmed by the anime's official channels.
More information is likely to arrive through future promotional updates, including trailers, key visuals and broadcast announcements.
What do we know about the cast and staff?
The Season 4 announcement has not yet provided a complete cast and production staff lineup.
Season 3 continued with the franchise's established cast, including Yuma Uchida as Iori Kitahara, Ryohei Kimura as Kohei Imamura and Chika Anzai as Chisa Kotegawa.
Its production was handled by animation studios ZERO-G and Liber, with Shinji Takamatsu serving as director, series scriptwriter and sound director.
Those credits provide context for the anime's most recent production, but the returning Season 4 staff should not be assumed until they are officially confirmed for the new season.
Grand Blue has entered a much faster sequel cycle
The speed of the Season 4 announcement is especially notable considering the anime's history.
The original *Grand Blue Dreaming* anime premiered in 2018. Fans then faced a wait of more than six years before the television anime returned with its second season.
The franchise has moved much faster since then. Season 3 was announced after Season 2 concluded, and the third season aired from July to September 2026. Season 4 has now followed the same pattern, receiving its confirmation immediately after the latest finale.
That does not establish when the fourth season will actually premiere, but it does mean viewers will not have to wonder whether the anime is continuing.

The manga began serialization in Kodansha's *Good! Afternoon* magazine in 2014 and is published in English by Kodansha under the title *Grand Blue Dreaming*.
