Based on the manga Demon Slayer: Kimetsu no Yaiba, which was serialized in Weekly Shonen Jump from February 2016 to May 2020 and has sold over 150 million copies, the series is set in the Taisho era, where flesh-eating demons roam. The story follows Tanjiro Kamado, a young boy whose family is slaughtered by demons. To save his demon-turned sister Nezuko, he joins the Demon Slayer Corps and begins a perilous journey.

The anime adaptation began airing in April 2019 with the Tanjiro Kamado: Unwavering Resolve Arc, followed by the Mugen Train Arc in theaters in October 2020. Subsequent seasons included the Entertainment District Arc in December 2021, the Swordsmith Village Arc in April 2023, and the Hashira Training Arc from May to June 2024. The Mugen Castle Arc, which follows directly after the Hashira Training Arc, is being produced as a trilogy of theatrical films.
