Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle: parents' guide
Best for ages 15 and up. Rated R for bloody violence throughout.
A long, relentless anime battle film for older teens who already follow the series; it picks up mid-story and will confuse newcomers. Most of its two and a half hours are fights between demon hunters and demons, with decapitations, severed limbs, gushing blood and a demon who eats people. Flashbacks add heavy material: several suicides are mentioned, a hanged body is shown, a boy is beaten bloody, and family members including children are killed. Swearing is limited to words like "damn" and "bastard," and there is no sexual content. Age 15 for the gore and the suicide content.
What's in it
Violence
StrongNearly nonstop and very bloody. Heads and limbs are cut off, a demon is stabbed in the eye, one fighter is absorbed by a demon, a man kills dozens with his bare hands in a flashback, and a demon devours corpses with audible crunching.
Language
MildAbout a dozen uses of "damn" and a handful each of "hell" and "bastard," plus "goddammit," "prick" and insults like "elderly hag." No s-words or f-words.
Sex and nudity
NoneNo sexual content. A brief flashback shows a young couple promising to marry, one character wears a low-cut outfit, and some men are shirtless.
Drinking, drugs and smoking
NoneNo drinking, smoking or drug use. A medicine meant to turn demons back into humans is a plot device, and poison is used as a weapon.
Scary or intense scenes
StrongSustained horror: monstrous demons, a villain who eats people, a hanged body in a flashback, and characters screaming in pain and grief as allies die. Memories of murdered families recur throughout.
Sensitive topics
- Suicide
- Death of a parent
- Death of a child
- Child abuse
Worth talking about
One villain's backstory shows how loss and cruelty twisted him into a killer. Can you understand why someone became cruel and still hold them responsible for it?
