Kimetsu no Yaiba: Yuukaku-hen

The Demon Slayer Corps are still reeling from the destruction caused by the Mugen Train incident. Despite being given time to rest and recover, they must continue their mission to protect the innocent from evil. A vicious demon has been terrorizing the women of the Yoshiwara Entertainment District and the Sound Pillar, Tengen Uzui, and his three wives have taken on the task of stopping it.

Unfortunately, Tengen soon loses contact with his wives and fears the worst. He calls upon Tanjirou Kamado, Zenitsu Agatsuma, and Inosuke Hashibira to help him investigate the district's most prominent houses and locate the Upper Rank demon.
