Why is Demon Slayer: Infinity Castle rated R? Anime movie’s divisive age rating

by

Demon Slayer: Infinity Castle is breaking box office records in North America, and it’s especially notable because it’s rated R, which is unusual for anime films.

This new movie kicks off a three-part film series based on the ‘Infinity Castle’ story from the Demon Slayer manga. It continues the story right after Season 4 of the anime, showing Tanjiro Kamado and the Demon Slayer Corps in their final showdown with Muzan Kibutsuji.

Infinity Castle was already a huge hit in Japan, and it’s become even more popular since opening in US theaters on September 12th. Worldwide, the movie has now earned over $353 million, not even including money from ticket and concession sales.

The movie is doing well both in theaters and with critics – it has a 98% rating on Rotten Tomatoes. However, if you’re planning to see it with children, it’s a good idea to check the age rating from Infinity Castle first.

Why is Demon Slayer: Infinity Castle rated R?

Even though it’s a cartoon, *Demon Slayer: Infinity Castle* received an R rating in the United States because of its frequent and graphic violent scenes.

The movie is rated R, meaning anyone under 17 must be accompanied by a parent or adult guardian. The MPA suggests parents research the film first to decide if it’s appropriate for their children.

It’s not unexpected, as the Demon Slayer anime has different age ratings depending on where you are. However, it’s generally recommended for viewers 14 and older because of its intense violence and bloody scenes.

Common Sense Media suggests Infinity Castle is appropriate for ages 14 and up due to scenes of graphic injuries and deaths.

The story delves into difficult and painful experiences, forcing characters to face their past traumas and truths. It tackles heavy subjects like suicide, murder, abuse, poverty, long-term illness, and social inequality. While characters do swear occasionally, the language is relatively mild, mostly limited to phrases like ‘god dammit,’ ‘bastard,’ ‘hell,’ and ‘damn.’

Age rating sparks debate

I’ve been seeing a lot of discussion about the game’s age rating online. Some people think it’s spot-on, others aren’t so sure, and honestly, one person I saw said it hasn’t really changed their mind either way. It’s definitely got people talking!

One Reddit user pointed out the interesting difference in ratings for *Demon Slayer*: it’s rated R in the US, but PG-13 in Japan. They shared that when they saw the first movie, it was filled with children who didn’t seem to notice or care about the R rating.

One viewer questioned if the new *Demon Slayer* movie was rated R, admitting they hadn’t seen it yet. Another responded that the series is known for its violence. A third viewer pointed out that the *Mugen Train* movie was also rated R, making the current rating predictable.

Someone likened it to the webcomic *Kpop Demon Hunters*, noting that while that series is generally family-friendly, it has a noticeably different feel than *Demon Slayer*.

Someone else added that the show is primarily aimed at younger audiences. While it’s considered appropriate for ages 12 and up in Japan, the content seems to be geared towards American tastes, and it will likely receive a rating for 15-year-olds in Mexico.

Okay, so Demon Slayer: Infinity Castle is finally out in theaters! I’m super excited to check it out. I also saw a story about a Demon Slayer cosplayer getting into trouble with the police – that’s wild! Apparently, Channing Tatum is now doing some English voice work for the show, which is awesome. And if you’re looking for other great anime to watch, Crunchyroll has a bunch of recommendations, too. Definitely a lot happening in the Demon Slayer world right now!
