Fans, this is it—the novel series of That Time I Got Reincarnated as a Slime wraps on Nov 29, 2025 with Volume 23, alongside a separate Side Story release. If you’re torn between the Special Edition (acrylic panel + 12 postcards) and the standard books, this guide breaks down the real differences, prices, and the Oct 16 pre-order deadline—no spoilers, just what you need to buy with confidence.
What’s Actually in Tensura Vol.23 and the Side Story
Vol.23 is the final main novel by Fuse with art by Mitz Vah, closing Rimuru’s journey. The Side Story adds a post-arc adventure featuring Rimuru × Hinata × Veldora, a creator talk (Fuse × Yuzo Takada), and an extra short after the finale—perfect if you want more world flavor without touching the core ending.
Special Edition Extras: Acrylic Panel and 12 Postcards
The Special Edition includes an acrylic panel (approx. W253×H130mm) of Rimuru plus the top-11 fan-voted characters with printed thanks & replica signatures, and 12 washi-style postcards (one per character). These bonuses are not in the regular edition.

Release: Nov 29, 2025 (both Vol.23 and the Side Story).
Special Edition pre-order deadline: Oct 16, 2025 (made-to-order; late availability not guaranteed).
