Demon Slayer: Mugen Train

Yes, *Mugen Train* became the highest-grossing anime film and Japanese film of all time, earning over $400 million globally during its initial run. It easily surpassed the previous record holder, Hayao Miyazaki's *Spirited Away*. The movie achieved this monumental financial success despite releasing during the height of the COVID-19 pandemic in 2020.

Yes, it is entirely canon, as it directly adapts the 'Infinity Train Arc' from Koyoharu Gotouge's original *Demon Slayer* manga. The film serves as a direct narrative bridge between the end of Season 1 and the start of Season 2. In fact, the events of the movie were later re-adapted into the first episodes of the anime's second season.

The movie features prominent supporting character Kyojuro Rengoku, the Flame Hashira, taking a leading role alongside the main trio. Tanjiro, Zenitsu, and Inosuke join Rengoku to investigate the disappearance of over 40 people on the titular train. The story provides vital backstory and an emotional climax for Rengoku's character.

The film was directed by Haruo Sotozaki, who also directed the anime television series for the Ufotable studio. Ufotable's signature blend of traditional 2D animation and stunning 3D CGI was on full display in the film's action sequences. Sotozaki's consistent direction ensured a seamless transition from the TV show to the theatrical feature.
