🧠 What Happened Before Season 4 (Season 3 Recap)
Before moving into Season 4, it is important to understand the foundation built in Season 3.
Season 3 focused heavily on:
- The Founding Festival arc
- Diplomatic relations between nations
- Rimuru’s role as a political leader
- Conflict with the Western Holy Church
- The confrontation with Hinata Sakaguchi
Unlike earlier seasons that focused more on action and rapid progression, Season 3 slowed things down to develop the world, alliances, and tensions between major powers.
These developments are essential because they directly lead into the conflicts seen in Season 4.

📅 Season 4 Release Date & Airing Status
That Time I Got Reincarnated as a Slime Season 4 officially premiered on April 3, 2026.
Current Status:
- ✔ Airing: Yes (ongoing)
- ✔ Format: Multi-cour (extended season)
- ✔ Episodes: Releasing weekly
Compared to previous seasons, this installment is expected to run longer, giving the anime more time to properly adapt major arcs from the light novel.
This extended format is important because the upcoming story arcs are larger in scale and require more development to fully capture their complexity.
📺 Episode Release Schedule
While exact episode counts are not always fully confirmed at the start, Season 4 follows a weekly release format.
Typically:
- New episodes are released once per week
- International streaming may vary slightly by region
- Subtitled versions are usually available shortly after release
Because this is a multi-cour season, fans can expect a longer continuous run, rather than a short 12-episode format.
📖 What Story Does Season 4 Cover?
Season 4 continues directly from the events of Season 3 and pushes the story into a much more intense phase.
Rimuru is no longer just building his nation — he is now managing a powerful and influential state that attracts global attention.
Key Story Focus:
- Expansion of the Jura Tempest Federation
- Political negotiations with other nations
- Strategic alliances and rivalries
- Rising threats from powerful enemies
- Large-scale conflicts
As Tempest grows stronger, other nations begin to see it as both an ally and a potential threat. This creates tension that eventually leads to confrontations.
At the same time, the series introduces stronger antagonists who challenge Rimuru not only in battle but also politically.
These developments push the story toward some of the most important arcs in the entire series.
