That Time I Got Reincarnated as a Slime Season 4 Part 2 Slated for July 2027 Alongside Clayman Revenge Spin-off Anime Adaptation
The expansive multimedia universe of the popular isekai fantasy franchise created by author Fuse has officially received major scheduling updates. Following the broadcast of the 24th and final episode of the fourth television anime season for That Time I Got Reincarnated as a Slime, production committees confirmed that the continuation of the narrative will debut in July 2027. This announcement was delivered alongside a simultaneous reveal regarding a brand-new television anime adaptation derived from Wataru Kajika’s spin-off manga series, That Time I Got Reincarnated as a Slime: Clayman Revenge, which is scheduled to premiere earlier in April 2027.
The dual announcements were broadcast via a special collaboration video released by the official franchise channels, generating widespread anticipation among fans globally. With animation production continuing to be handled by studio 8bit, the expanding slate highlights the enduring commercial and cultural success of the intellectual property across light novels, manga, and television broadcasts.
Chronology of the Franchise and Recent Season Details
The journey of Rimuru Tempest from a mundane corporate worker to a powerful demon lord began as a humble web novel published on the user-generated content platform Shousetsuka ni Narou between February 2013 and October 2016. Recognizing its massive potential, Micro Magazine acquired the rights, publishing the work under their GC Novels imprint starting in May 2014 with illustrations provided by Mitz Vah. The original light novel series officially concluded with its 23rd volume in November 2025, cementing its status as a monumental pillar of the modern isekai genre.
Parallel to the light novels, Taiki Kawakami launched a manga adaptation in Shounen Sirius in March 2015. This manga adaptation serves as the primary visual blueprint for the main television anime series. The fourth season of the main anime adaptation commenced airing on April 3, bringing high-definition fidelity to Kawakami’s illustrations, with international streaming handled by Crunchyroll via simultaneous broadcasts featuring multiple subtitle and dub options.
The television anime adaptation history spans nearly a decade:
- First Season: A 24-episode run broadcast in Fall 2018, produced by studio 8bit.
- Second Season: Broadcast in split cours during Winter 2021 and Summer 2021.
- The Slime Diaries (Tensura Nikki): The franchise’s first spin-off anime aired in Spring 2021.
- Third Season: A 24-episode run broadcast in Spring 2024.
- Fourth Season Part 1: Aired through mid-2025, culminating in its 24th episode announcement.
- Fourth Season Part 2: Scheduled for a July 2027 premiere.
Expanding the Narrative: Clayman Revenge Anime Adaptation
The announcement of the Clayman Revenge anime adaptation adds a compelling layer to the franchise’s overarching lore. Based on the spin-off manga written by Wataru Kajika, which began serialization in Shounen Sirius in April 2022 and reached its ninth compiled volume in August 2025, the narrative explores an alternate path or continuation for the character Clayman, colloquially known as the Marionette Master.
The official synopsis provided by publisher Kodansha poses an intriguing premise: following the dramatic climax and final scream heard during the Walpurgis Festival, the ambitions of the Marionette Master were widely assumed to be extinguished permanently. However, through the unpredictable whims of fate or the grand design of the world itself, Clayman’s theater is granted one final performance. Kodansha currently releases English translations of the spin-off manga digitally via its K Manga platform.
Production Staff and Voice Cast Details
To maintain the high artistic standards established by the main series, studio 8bit has assembled a seasoned roster of creative talent for the Clayman Revenge project:
- Director: Kentarou Sugimoto, known for his episode direction work on Blue Lock.
- Series Composition: Yuuji Haibara, who previously directed Tensura Nikki: Tensei shitara Slime Datta Ken.
- Character Design: Asumi Hashimoto (sub-character designer for Mahouka Koukou no Rettousei 3rd Season) and Hideki Sakai (chief animation director for Tensei shitara Slime Datta Ken 2nd Season).
- Animation Production: 8bit.
Furthermore, producers confirmed that the core voice acting cast from the primary television anime series will reprise their respective roles within the spin-off, ensuring continuity and vocal fidelity for returning characters who interact with Clayman during this unexpected narrative arc.
Supporting Data and International Reach
The global footprint of the franchise is heavily supported by extensive publishing and licensing agreements across multiple continents. In North America, Yen Press acquired the English-language publishing rights for the original light novel series in April 2017, releasing the 22nd volume in February 2010. Meanwhile, Kodansha USA licensed the manga adaptation in October 2016, with the 29th volume arriving on March 31 and the 30th volume slated for an October 27 release.
The cross-media synergy between print publications, digital chapters on K Manga, and high-profile television broadcasts has established a robust ecosystem. By staggering the release of Clayman Revenge in April 2027 and the second part of the fourth main season in July 2027, the production committee ensures sustained viewer engagement throughout the calendar year.
Broader Impact and Industry Implications
The continuous investment in the Tensura IP underscores a broader industry trend where established fantasy franchises are granted expanded lifecycles through multi-season commitments and spin-off adaptations. While many anime projects conclude after a single successful run, studios like 8bit have successfully cultivated long-term loyalty by treating the source material as an evolving cinematic universe.
The decision to adapt Clayman Revenge specifically points to a growing appetite for villain-centric redemption or alternative perspective arcs within popular fantasy properties. By exploring secondary characters with deep backstories, the franchise deepens its world-building without diluting the primary progression of Rimuru Tempest and the Jura Tempest Federation. As production moves forward toward the 2027 broadcast dates, anticipation remains high among both domestic Japanese audiences and the vast international fan base reached through platforms like Crunchyroll.
