A lot or a little?

The parents' guide to what's in this movie.

Positive Messages

Underlying the violence is a focus on the importance of letting go of selfish desires for the greater good. Themes of family, teamwork, perseverance, compassion, and concentration.

Positive Role Models & Representations

While many characters are lured into doing terrible things for self-gain, Rengoku is a proud mentor to lower-level slayers and his younger siblings. He teaches patience, encourages characters to persevere despite hardship or judgement. Rengoku and Tanjiro place great value in human life and work to protect everyone, despite others who believe it's important to make sacrifices.

Violence

Lots of body horror and fantasy violence. Characters, including young children, bleed profusely. Demons transform their bodies into squishy, gory shapes. Characters are forced to end their own lives.

Sex
Language

Language includes "dammit," "crap," and "hell."

Consumerism

Demon Slayer merchandise is available for purchase. 

Drinking, Drugs & Smoking

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.

Talk to your kids about ...

  • Families can talk about teamwork. How do the Demon Slayers work together to defeat the enemy?

  • Many characters in this film are lured into doing terrible things for their own self-gain. Why do you believe they choose to do this? How does the film show the importance of letting go?

  • How does the violence in Demon Slayer: Kimetsu No Yaiba: The Movie: Mugen Train compare to what you've seen in live-action movies with similar themes and action? Does the fact that it's animated affect the impact of the violence?
