Kadokawa has clarified that the upcoming 32nd volume of the That Time I Got Reincarnated as a Slime manga is not the series' final installment. An article on Dengeki Online initially stated the volume was the last, but has since corrected the information to indicate it is the "latest volume." The staff cited an error in translation, mistaking "saishūkan" (final volume) for "saishinkan" (latest volume).

The 32nd volume of Taiki Kawakami's manga adaptation is scheduled to ship on June 9. A special edition will be available, featuring a pamphlet with a full-color version of chapter 133, "The Daemon's Whispers." This chapter was previously included in volume 31.

The manga, based on Fuse and Mitz Vah's light novel series, launched in Kodansha's Monthly Shonen Sirius in March 2015. The 31st manga volume was released on February 9. While the manga is the basis for the ongoing anime adaptation, the original light novel series concluded with its 23rd volume in November 2025. Yen Press handles the English release of the novels, while Kodansha USA publishes the manga in English.
