Derpy Adopted by Rumi & Jinu: a KPop Demon Hunters fan animation
A 20-minute animated fan story about family, magic and belonging, built for emotionally engaged 6 to 7 year olds.
A fan-made animated story following a cat named Derpy adopted into an unusual family, scored 80 for comfort with a neutral overall energy effect. Companions peaks at 95 for 6 to 7 year olds, the strongest play style here by some distance, so it plays best for a child who loves character relationships and belonging themes. Yellow-to-green sits at a moderate 60, so it's a better daytime watch than a wind-down tool.

Why it works
This fan animation follows Derpy, a cat adopted into an unusual family, cut at a brisk 4.2 second average shot length with warm, moderate-energy pacing throughout. It has a natural endpoint and no cliffhanger, so the 20-minute story resolves fully rather than leaving things hanging.
That relationship-driven, emotional storytelling is why Companions peaks at 95 for 6 to 7 year olds, well ahead of Dreamers at 80 and Entertainers at 75: this suits a child who's drawn into family bonds and belonging as much as the fantasy setting. Our curators name children who love animals, emotional storytelling and fantasy fans as the best fit, while flagging children sensitive to thunder or storms as a group to watch for.
On regulation, yellow-to-green sits at a moderate 60 and blue-to-green at a stronger 85, so it's better for lifting a flat mood than for settling a wound-up one. Sensory intensity is moderate, with loud music and bright colours both flagged, and our data notes themes of sadness and separation may need a gentle hand for younger viewers specifically.

Questions parents ask
What age is this best for?
It peaks at 6 to 7 years old, where Companions scores 95, well ahead of every other play style. Our curators name children who love animals, emotional storytelling and fantasy as the best fit.
Is it good for calming a wound-up child?
Not especially. Yellow-to-green sits at a moderate 60, so it's better used to lift a flat mood (blue-to-green scores 85) than to settle a wound-up one.
Is there anything emotionally heavy in it?
Our data flags themes of sadness and separation, and thunder or storms, as things to know about, alongside illness themes for slightly older children. It's still rated safe overall, but worth a quick preview if your child is sensitive to any of those.
Is it suitable for a sensory-sensitive child?
Mostly, yes: it's marked ASD-safe, PDA-safe, anxiety-safe and ADHD-friendly. Loud music and bright colours are flagged though, and it isn't marked sensory-avoiding safe, so a sound-sensitive child may need a preview first.
