That Time I Got Reincarnated as a Slime is in the middle of its most ambitious anime season yet. Season 4 premiered on Crunchyroll on April 3, 2026, and is scheduled to run for five cours total.

The franchise is also expanding theatrically. Crunchyroll and Sony Pictures Entertainment announced That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea, an original standalone side story set after season three, directed by Yasuhito Kikuchi with animation by Eightbit.

Merchandise and publishing activity remain strong. The manga's Volume 32 topped the Amazon Kindle weekly bestseller chart in late May. Banpresto released a 26 cm Diablo figure in its ESPRESTO crane game line in June, completing a three-character set with previously released Rimuru and Milim figures. A pop-up shop in Yokohama offered advance goods from the series alongside 10 other anime and game franchises in early June.
