The Tensura franchise is mid-run across several fronts: season 4 is airing an extended five-cour run, the film Tears of the Azure Sea is streaming on Crunchyroll and U-NEXT after its theatrical run, and a bunny-costume collaboration with C4 Connect's Houchishoujo is running through September 28, 2026. A manga volume and merchandise lines continue alongside.
The most recent movement for That Time I Got Reincarnated as a Slime is in games and licensing. C4 Connect's Houchishoujo is running a collaboration from September 8 to September 28, 2026 in which Rimuru, Milim, and Shion appear in original bunny girl costumes with newly recorded voice lines; Shion is free through the event, with item exchange open until October 1.

The animated side rests on season 4, which debuted on April 3, 2026 and is set for a five-cour run.

The season placed third in U-NEXT's first-half 2026 viewership ranking (January 1 to June 8) and second in the ending theme poll by Anime! Anime! readers for the summer. Its source manga is moving too: volume 32 topped Oricon's June 2026 monthly comic ranking at 270,780 copies and the Amazon Kindle chart before that, and the volume was initially reported as the final one before being corrected to the latest.
The film Tears of the Azure Sea, a standalone side story set after season three, opened in Japan on February 27, 2026 and ranked third in its opening weekend before Crunchyroll began streaming it in several regions including the UK and US with subtitles and a dub. Crunchyroll and Sony had announced a May 1 theatrical release in the US and Canada, with Yasuhito Kikuchi directing and Eightbit animating. Voice actors Miho Okasaki and Megumi Toyoguchi, who play Rimuru and Raphael, said at Anime Expo 2026 that they still do not rehearse together before recording. Merchandise runs from COSPA apparel to a Banpresto Diablo figure, 26 cm, shipping June 9.
