Yu Tanaka is writing the Reincarnated as a Sword light novel. The novel was first published on the Shosetsuka ni Naro website in October 2015. GC Novels started publishing it in the light novel format in 2016 with illustrations by LLO. A manga adaptation by Tomowo Maruyama is currently ongoing, along with a spin-off manga Reincarnated as a Sword: Another Wish by Hinako Inoue, which began in June 2020. Seven Seas Entertainment licensed the light novel, the manga, and the spin-off manga. Studio C2C animated the adaptation.
Tensura is a Japanese light novel series written by Fuse and illustrated by Mitz Vah. The anime adaptation actually follows the manga, which features illustrations by Taiki Kawakami.
