Koriusu no Yume was a text story included in a bonus extra booklet with the Blu-ray Disc release of the second That Time I Got Reincarnated as a Slime season. It became a major story inspiration for the Scarlet Bond film. The "epic spectacle story" is set between the first two television seasons when Rimuru faces intrigue swirling around the Coleus Kingdom. Takuma Terashima (Satoru Mikami) is performing the opening theme song.

Fuse serialized the story on the "Shōsetsuka ni Narō" (Let's Become Novelists) website from 2013 to 2016, and the series has since garnered over 400 million page views. Micro Magazine began publishing the series in print in 2014. The novels entered their final arc in the 18th volume in March 2021. Fuse also previously announced that he is considering writing side stories (spinoffs) after the current series is complete. Fuse is planning to end the series by its 22nd volume. Yen Press publishes the novel series in English.

The first television anime of Taiki Kawakami's manga, itself an adaptation of the light novel series, premiered in October 2018. Crunchyroll streamed the anime, and Funimation streamed an English dub.

The second television anime season premiered its first cours (quarter of a year) in January 2021. The television anime of Shiba's spinoff manga The Slime Diaries: That Time I Got Reincarnated as a Slime (Tensura Nikki Tensei Shitara Slime Datta Ken) then premiered on Tokyo MX in April 2021. After The Slime Diaries ended, the second cours of the second season began in July 2021 — for nine straight months of television anime from the franchise that year.

Both Funimation and Crunchyroll streamed the second part. Funimation also streamed an English dub.

The franchise's latest film titled Tensei Shitara Slime Datta Ken: Guren no Kizuna (That Time I Got Reincarnated as a Slime: Scarlet Bonds) premiered in Japan in November 2022.
