Infinity Castle – Part 1: Akaza Returns also grossed 5.52 billion yen ($37.3M) in its first three days, breaking three records for opening day, opening weekend, and single-day performance in Japanese box office history. Its first-week box office total also exceeded that of Mugen Train, marking an explosive debut.

Based on the popular manga serialized in Weekly Shonen Jump from February 2016 to May 2020, Demon Slayer is set in the Taisho era, where man-eating demons roam. It follows Tanjiro Kamado, a boy whose family was slaughtered by demons, and his journey to save his sister Nezuko—who has become a demon—by joining the Demon Slayer Corps and confronting those responsible. The manga has sold over 220 million copies worldwide.

The anime debuted with Tanjiro Kamado: Unwavering Resolve Arc in April 2019, garnering widespread attention. The 2020 film Mugen Train became a cultural phenomenon, grossing over 51.7 billion yen ($349.3M) globally.

The franchise expanded with video games and stage adaptations, followed by anime arcs Entertainment District (Dec 2021), Swordsmith Village (Apr 2023), and Hashira Training (May–Jun 2024). The new film trilogy, Infinity Castle, pits the Demon Slayer Corps against their greatest enemy, Muzan Kibutsuji, and the Upper Rank Demons in a final showdown set in the Infinity Castle. The film is currently screening in 452 theaters nationwide, including 59 IMAX screens.
