Kimetsu no Yaiba: Katanakaji no Sato-hen

After his sword is damaged yet again, Tanjiro travels with Nezuko to the hidden Swordsmith Village in search of a replacement. There he crosses paths with Mist Hashira Muichiro Tokito and Love Hashira Mitsuri Kanroji while trying to persuade a smith to restore the weapon he needs for battle. The secluded village, however, is about to lose the secrecy that has protected it for generations.

The death of an Upper Rank has forced Muzan to move his strongest demons, and Hantengu and Gyokko soon descend on the settlement. As the villagers fight to protect their forges and their lives, Tanjiro, Nezuko, and the Hashira are drawn into a battle with no safe retreat. If the village falls, the Demon Slayer Corps may lose one of the foundations of its war against demons.
