That Time I Got Reincarnated as a Slime: Light Novel reaches its grand finale after 12 years

After running for over a decade, the light novel of That Time I Got Reincarnated as a Slime has officially concluded. With the final 23rd volume released on November 29, 2025, the story of Rimuru is now over, and fans are still not ready to say goodbye. With the final volume now also out, it marks the end of the monumental journey of our protagonist, who has made quite an impression in the isekai genre and stands out as an interesting story in the modern fantasy series.

While those who read the light novel are upset about this news, there is hopeful news, and fans can rest easy as Rimuru Tempest’s world is far from finished. That Time I Got Reincarnated as a Slime was first published in 2013, before we got the translations from 2014. Written by Fuse, the synopsis followed any other generic isekai story format; Satoru Mikami was an ordinary 37-year-old salaryman in Japan who was unexpectedly killed and then found himself reincarnated in a fantasy world.

He is now a slime and acquires the name of Rimuru Tempest, and continues to become a leader who builds a strong nation and continues to become one of the strongest characters in this world. With That Time I Got Reincarnated as a Slime Volume 23 now labeled as the “grand conclusion” to the main storyline, the series closes a major chapter, both literally and symbolically.

The good news part of this information is that the anime has just covered half of the content of the light novel. This means that Rimuru will still be making an appearance, and those who have read this light novel will still have the opportunity to watch their beloved character make moves in animation format.
