Grand Blue Season 4 is happening
Good news for fans of chaotic anime comedy: Grand Blue is getting a fourth season.
According to MyAnimeList News, the announcement came after the 12th and final episode of Grand Blue Season 3, also known as Grand Blue Dreaming Season 3. The anime’s official website also shared a new announcement visual to mark the reveal.
For now, that is the big headline: Season 4 is in production. The source does not list a release window, episode count, streaming platform, staff line-up, cast update, or regional availability for the new season.
Quick timeline so far
The anime has had a pretty unusual stop-start rhythm across the years.
The first season was produced by Zero-G and aired for 12 episodes in Summer 2018. After that, the series went quiet on the anime front for a long stretch.
The second season eventually arrived in Summer 2025. Then Season 3, produced by Zero-G and Saber Works, premiered on July 7.
Now, with Season 3 wrapped, the production committee is already moving ahead with Season 4. That is a nice signal that the series still has enough momentum to continue beyond just a comeback nostalgia run.
The source also notes that Amazon Prime Video streamed the first season, while Crunchyroll simulcasted the second season. However, MyAnimeList’s report does not specify regions in the provided text, so don’t treat that as a Malaysia-specific platform confirmation for the upcoming season.
Why this matters for Malaysia and SEA anime fans
Analysis/inference: For Malaysian and SEA viewers, the key thing here is consistency. Anime fans in this region are used to long waits between seasons, especially for comedy titles that are not always treated like big shounen tentpoles. Grand Blue coming back for Season 2, then Season 3, and now getting Season 4 suggests the franchise has managed to keep enough energy behind it.
That matters because comedy anime can be very dependent on timing. If a show disappears for too long, casual fans move on, memes fade, and new viewers may not bother catching up. A confirmed fourth season gives the series a better chance of staying in the weekly conversation once more details arrive.
Analysis/inference: It also helps that Grand Blue has a clear identity. In a seasonal anime calendar packed with fantasy, isekai, action sequels, and idol projects, a loud comedy series can stand out just by being something different. For viewers who want a break from power-scaling arguments and lore homework, this kind of announcement is genuinely welcome.
What we still don’t know
At this stage, the announcement is early. The important missing details are:
- When Season 4 will air
- Which studio or studios will handle the new season
- Whether the main staff and cast are returning
- Where it will stream internationally
- Whether there will be a new trailer or key visual beyond the announcement visual
So yes, get excited — but keep expectations measured until the official channels reveal more.
For now, the takeaway is simple: Grand Blue Season 4 is in production, and the anime’s comeback run is continuing.
