What's the Story?
In DEMON SLAYER: KIMETSU NO YAIBA: THE MOVIE: MUGEN TRAIN, heroes Tanjiro Kamado (voiced by Natsuke Hanae), Inosuke Hashibara (Yoshitsugu Matsuoka), and Zenitsu Agatsuma (Hiro Shimono) are given their next slayer assignment on a public train. The team and their mentor, a high-level Demon Slayer named Rengoku (Satoshi Hino), must defeat one of the strongest demons they've encountered so far -- one who has the power to control dreams.
Is It Any Good?
This fun, lively film acts as a heartfelt extended episode of the Demon Slayer series. The characters in Demon Slayer: Kimetsu No Yaiba: The Movie: Mugen Train bring their same charm and passion to their battles. The action is exciting and flashy but easy to follow. Despite some frightening imagery, the film pushes important lessons for many of its characters, such as being able to let go of the past in order to move forward.
Although the storyline is fairly straightforward, certain information from the series is needed in order to fully understand who the characters are and what their ranking means within the Demon Slayer universe. Despite this, viewers who haven't seen the series can still find entertainment in this film. But know that the level of horror and use of suicide in the movie may be too intense for younger kids.
