That Time I Got Reincarnated as a Slime manga sales: series total versus manga alone
Publisher totals for Slime bundle light novels, manga and spin-offs, so the useful question is what each number actually counts.
Published: 2026-10-13. Updated: 2026-10-13.
Short answer: The best sourced total is 45 million copies in circulation, reported by Anime Corner on September 22, 2025. That figure covers the whole franchise's publications, not the manga alone. The manga's own sales are only visible volume by volume: Oricon put volume 32 at 270,780 copies in June 2026, ranking first in the monthly comic chart.
What the 45 million covers
Anime Corner's September 22, 2025 article says the franchise has 45 million copies in circulation across its publications and calls it the best-selling light novel franchise of all time. The article does not split the total between light novels, manga and other formats, and it does not say when the count was taken.
That is the important caveat. The 45 million is a series total. It cannot be quoted as manga sales, and there is no public figure we found that isolates the Kodansha manga.
Manga alone or whole series?: Every cumulative number we found for Slime is a series total. Earlier examples also combine formats: Otaku USA reported 30 million copies in print in January 2022 for the novels, manga adaptations and spin-offs combined, and 20 million in September 2020 for the novels.
How the series total has moved
The dated figures we opened show growth, but they are not one consistent series. September 2020: over 20 million copies in print, a figure that article attributes to the novels. January 2022: 30 million in print for novels, manga adaptations and spin-offs combined. September 2025: 45 million in circulation across publications.
Because the counting basis differs between pieces (print versus circulation, novels versus everything), differences between them should not be read as clean annual growth.
Manga volumes on the Oricon chart
Anime News Network reported on July 9, 2026 that volume 32 of the Kodansha manga topped Oricon's monthly comic ranking for June 2026 with 270,780 copies, covering estimated print sales at Japanese retail outlets from June 1 to June 28. The second and third places were Chainsaw Man volume 24 (151,140) and Dan Da Dan volume 24 (122,830).
This is a one-volume, one-month, Japan-print figure. It shows current demand for new volumes but cannot be added up into a manga total.
Where public evidence stops
We found no public manga-only cumulative total, no year-by-year manga series total, and no regional split.
