We fans already know how wild Rimuru’s journey has been. From a simple slime to a nation leader, every season gave something bigger than the last. The world-building, the fights, and the politics—everything kept growing with Rimuru’s power. That’s why, after Season 3 ended, we all had one big question in our heads.
Is Reincarnated as a Slime Season 4 happening? And if yes, when? Now that the official update is out, let’s break down every single detail from confirmation to expected plot and more.
Has That Time I Got Reincarnated as a Slime Season 4 Been Officially Confirmed
Yes, That Time I Got Reincarnated as a Slime Season 4 is officially confirmed. On September 27, 2024—the same day Season 3 ended—a special PV and new visual were released. In the video, Rimuru appeared inside Tempest Manor, holding a meeting. And then, the voice of Great Sage directly revealed that both Season 4 and a second movie were now in production.
The announcement was made through the anime’s official website and X (formerly Twitter). Studio 8bit also confirmed that they would continue the animation work for the new season. So, Reincarnated as a Slime Season 4 is not just a plan. It is already in production. The episode count or release window has not been announced yet, but the green light is already there.
That Time I Got Reincarnated as a Slime Season 4 Release Date (Estimated)
There is no official date, but it is almost clear that we will not get Reincarnated as a Slime Season 4 before 2026. The reason is simple. The movie Tears of the Azure Sea is already scheduled for February 2026, and the studio is fully focused on finishing that first.
Season 3 ended on September 27, 2024. And the announcement for Reincarnated as a Slime Season 4Season 4 and the movie came on that exact day. But with how much effort the movie needs, fans and discussion forums believe the anime will likely return in late 2026 or sometime in 2027.
This is also based on the pattern from before. Season 2 and Season 3 also had long gaps. So, the best guess right now is late 2026 or early-to-mid 2027.
What Will Happen in Season 4? Expected Plot and Arcs
The next season will be full of political games, powerful enemies, and some major setup for future battles.
Majin Behind the Scenes:
Rimuru’s new nation Tempest, is finally getting noticed. His projects like the dungeon, have made Tempest famous. Now, Rimuru wants to join the Western Nations’ Council. But not everyone is happy with that. Secret enemies are planning to stop him even before any war begins.
A New Demon Lord Appears:
The pre view showed Rimuru in a serious council scene with his top people. Many fans believe a powerful Demon Lord will either return or enter the picture. This could become the next major threat.
Setup for the Empire War Arc:
Some fans believe that Reincarnated as a Slime Season 4 might start the Empire War Arc by the end. It may not go into the full war yet, but the tension and buildup can begin. That means we may get a serious ending that sets the stage for Season 5.
Episode Count & Flow:
If it follows the usual 24-episode pattern, then we might get around 3 arcs in one season—Majin, Awakening, and maybe the beginning of the Empire War. It is very unlikely they will try to cover everything in one go.
What Light Novel Volumes Will Season 4 Cover?
Season 4 is expected to adapt Volume 10 and Volume 11 of the light novel. It may also include the first one or two chapters of Volume 12, but nothing more.
This follows the same pattern as before. Reincarnated as a Slime Season 3 covered Volumes 7 to 9, so naturally, 10 and 11 are next. Volume 12 is more of a beginning for the Empire War Arc, so if they rush into it, it will not feel complete. Most predictions say that Volume 12 will be saved for Season 5.
Production and Studio Info: Who Is Making Season 4?
Studio 8bit is once again in charge of animation for Reincarnated as a Slime Season 4. They have handled the anime since the very beginning in 2018. In 2024, the studio officially became part of Bandai Namco Filmworks, which has now become the main production lead.
The team behind Season 3 is also coming back:
- Director: Atsushi Nakayama
- Series Composition: Toshizo Nemoto
- Character Design: Ryōma Ebata
- Music: Elements Garden
The studio has not announced how many episodes Reincarnated as a Slime Season 4 will have. But fan listings and staff updates confirm that the anime is already under production. With Bandai Namco backing it fully, the production team is expected to maintain the same animation and story quality as before.
