Demon Slayer: Kimetsu no Yaiba is based on the manga series by Koyoharu Gotouge, originally serialized in Weekly Shonen Jump from February 2016 to May 2020. With over 150 million copies in circulation, the story is set in the Taisho era, where man-eating demons roam the land. It follows Tanjiro Kamado, a boy who joins the Demon Slayer Corps to turn his demonized sister Nezuko back into a human after their family is slaughtered.

The anime began with the TV adaptation Tanjiro Kamado, Unwavering Resolve Arc airing from April to September 2019, followed by the blockbuster film Mugen Train in October 2020. Subsequent arcs include the Entertainment District Arc (December 2021), Swordsmith Village Arc (April 2023), and Hashira Training Arc (May–June 2024). The Mugen Castle Arc picks up directly after the final episode of the Hashira Training Arc and is planned as a trilogy of theatrical films.

Story Overview: Demon Slayer – Mugen Castle Arc

Tanjiro Kamado, determined to restore his demon-turned sister Nezuko to humanity, joins the Demon Slayer Corps. Alongside comrades Zenitsu Agatsuma and Inosuke Hashibira, Tanjiro battles formidable demons, growing stronger and forming unbreakable bonds.

In previous arcs, Tanjiro fought alongside elite Hashira warriors: the Flame Hashira Kyojuro Rengoku in Mugen Train, the Sound Hashira Tengen Uzui in Entertainment District, and the Mist and Love Hashira—Muichiro Tokito and Mitsuri Kanroji—in Swordsmith Village.

During the intensive Hashira Training to prepare for the ultimate showdown against the demons, the demon lord Muzan Kibutsuji infiltrates the Demon Slayer Corps headquarters, the Ubuyashiki Estate. As the Hashira and Tanjiro rush to protect their leader, they are suddenly cast into a mysterious dimension.
