Update [Dec. 2, 2021]: We've got all you need to know to watch Demon Slayer season 2: Entertainment District Arc which is finally debuting soon.

Hop on board! It's time to watch Demon Slayer: Mugen Train online — and you don't even need to pay. Yes, you can join Tanjiro, Nezuko, Zenitsu and Inosuke as they look to assist the Flame Hashira Kyōjurō Rengoku, as he hunts a particularly troublesome demon. 

For the uninitiated, Demon Slayer: Mugen Train is a highly popular anime film that was one of the first movies to dominate the domestic box office once theaters re-opened in the states. It sits behind Pokemon the Movie in the list of top-grossing anime features in the U.S, with a global gross of approximately $475 million USD and counting.

Unfamiliar, but curious about the movie? It's the continuation of an anime series whose first season is currently on Netflix. A second season is coming, but there is no date.
