TenSura’s Massive Success
That Time I Got Reincarnated as a Slime is the best-selling light novel series ever, with 45 million copies released across all its editions. The story was originally self-published by Fuse on the Shosetsuka ni Narou platform from 2013 to 2016 before being picked up by Micro Magazine in 2014.
Since then, TenSura has grown into a major franchise, including games, an anime adaptation produced by studio 8-bit, and multiple manga adaptations.
The Future of the TenSura Series
Although the light novel is coming to an end, big plans for the anime continue. Movie 4 is set to premiere on February 27, 2026, while Season 4 of the anime series is currently in production. This means that even though the main story of TenSura concludes, fans still have plenty of exciting content to look forward to.
