That Time I Got Reincarnated as a Slime: Season 4 FAQ

If you’ve spent any time around anime fans online, you’ve probably noticed that one slime gets talked about a lot. That Time I Got Reincarnated as a Slime has quietly become one of the most popular fantasy series of the last decade, and with season 3 now behind us, the questions are piling up.

Seasons: 3 · Total episodes: 66 (as of 2024) · IMDb rating: 7.8/10 · MyAnimeList score: 8.1/10 · Studio: 8bit

Five key facts about the series, at a glance.

Is Reincarnated as a Slime getting a season 4?

Yes, it is. After the third season wrapped in 2024, Anime News Network reported that a fourth season was in production. The premiere date is set for 2026-04-03 in Japan on NTV’s Friday Anime Night block at 11:00 p.m. JST. The implication: fans finally have a concrete date after years of waiting.

Is there a season 5 confirmed?

• No fifth season announcement has been made as of 2025.
• The fourth season may cover multiple cours, which could mean a long broadcast run before any renewal decision.

Given the fourth season’s five-cour plan—with the first two airing consecutively—it’s plausible the production team is waiting to see audience reception before committing further.

When will season 4 release?

• 2026-04-03 — the date confirmed across Rotten Tomatoes, MyAnimeList, and Anime Corner.
• Crunchyroll will stream the season as it airs.

The five-cour structure means the story will run for longer than a standard season, possibly through late 2026 or into 2027.

Is the slime anime good?

General reception has been warm. The series holds a 7.8/10 on IMDb and a 8.1/10 on MyAnimeList, with many reviewers praising its world-building and character writing.

What is the critical reception?

• The series is frequently noted for its political intrigue and governance themes, rare for an isekai.
• Reviewers on Rotten Tomatoes highlight the balance between comedy and serious stakes.

Is the anime bad?

• Some critics argue the pacing in season 2 drags, especially the council-heavy episodes.
• A segment of viewers finds the power scaling problematic—Rimuru becomes so strong that tension drops.

The pattern: the series excels at building a nuanced fantasy world, but the pacing can frustrate viewers expecting constant action.

Is there LGBTQ in That Time I Got Reincarnated as a Slime?

This is one of the most asked questions about the series, and the answer requires separating canon from fan reading. The series includes Luminous Valentine, a character associated with LGBTQ themes in fan discussion, but there are no explicit same-sex relationships shown in the anime.

Who is Luminous Valentine?

• Luminous Valentine is a demon lord who appears in later arcs, known for her androgynous design and close bond with female characters.
• Her gender presentation is intentionally ambiguous, leading to widespread fan interpretation.

Are there any LGBTQ relationships?

• No canon same-sex couples exist in the anime or light novel to date.
• Rimuru is genderless—reincarnated without a biological sex—and uses male pronouns in the English translation, but the original Japanese occasionally uses gender-neutral language.
• Some side characters have ambiguous attractions, but nothing is confirmed.

The catch: the series offers plenty of material for queer reading—genderless protagonist, fluid-presenting characters—but stops short of explicit representation. Whether that’s enough depends on what you’re looking for.

How long is slime season 4?

The fourth season hasn’t aired yet, so its exact episode count is unknown. But the structure gives clues about the length.

How many episodes are in each season?

• Season 1: 24 episodes
• Season 2: 12 episodes
• Season 3: 24 episodes
• Season 4: unknown, but planned as five split cours

Wikipedia’s season 4 page describes a five-cour structure. Typically, one cour equals 10-13 episodes. If the first two cours air consecutively, that’s roughly 20-26 episodes for the initial block, with three more to follow.

What is the total runtime?

• At 24 minutes per episode, 20-26 episodes means ~8-10 hours of content for the first block alone.
• The full five-cour plan could run 50-65 episodes total, comparable to season 1 and 3 combined.

What this means: season 4 is shaping up to be the longest season yet in terms of broadcast calendar, if not episode count.

What is Rimuru’s final form?

This is a popular question among light novel readers who want to know where the anime is headed. In the source material, Rimuru undergoes several major transformations.

What are Rimuru’s different forms?

• Initial Slime form
• Humanoid form (after absorbing Shizu)
• Demon Lord form (after the Harvest Festival)
• True Dragon form (also called “Ultimate Slime”)

What is the ultimate slime form?

• The Ultimate Slime form is Rimuru’s final evolved state in the light novel, making him a True Dragon.
• In this form, Rimuru gains powers comparable to Veldora and the other original dragons.

The trade-off: Rimuru becomes one of the most powerful beings in the setting, which removes some traditional underdog tension but opens up large-scale political and cosmic storytelling.
