Fans of the incredibly popular ‘That Time I Got Reincarnated as a Slime’ series should mark their calendars, as the highly anticipated 23rd and final volume of the light novel is slated for release in Japan on November 29, 2025. This climactic installment promises to bring the beloved isekai fantasy story, crafted by author Fuse and beautifully illustrated by Mitz Vah, to its conclusion.
Japanese publisher Micro Magazine recently unveiled the striking cover art for the 23rd volume, freshly drawn by Mitz Vah, offering a tantalizing glimpse of what’s to come. But that’s not all for dedicated readers! In a special treat for collectors, the bonus illustration for the 23rd volume’s special edition will feature Mitz Vah’s unique rendition of the top 11 characters from a fan popularity poll held earlier this year, alongside the iconic protagonist, Rimuru. This special artwork celebrates the characters that have captured the hearts of millions.
The ‘That Time I Got Reincarnated as a Slime’ saga began its life as a web novel on a self-publishing platform, where Fuse serialized it from 2013 to 2015. Micro Magazine quickly recognized its potential, acquiring the series and beginning its publication under their GC Novels imprint in 2014. Since then, the story of Rimuru has expanded far beyond the pages of the light novel, evolving into a true multimedia phenomenon.
The series boasts a highly successful manga adaptation by Taiki Kawakami, an immensely popular anime series, and even a stage play, cementing its place in modern fantasy. Its incredible reach is further highlighted by a cumulative circulation of over 56 million copies across all its iterations.
For those unfamiliar with the adventures of Rimuru, the story follows Mikami Satoru, an ordinary corporate worker who, after a tragic encounter, finds himself reborn in an alternate world—not as a hero or a wizard, but as a humble slime. Renamed Rimuru, he embarks on an extraordinary quest to build a welcoming and inclusive world for all races, encountering powerful allies and formidable foes along the way. Get ready to experience the final chapter of this unforgettable journey.
