This Kids K-Pop Demon Hunter Rumi Costume brings the high-energy world of anime action heroes to Book Week and cosplay events. The four-piece set includes everything your child needs to transform into the edgy martial-arts character — bright yellow jacket, hot pink shorts, leg sleeves, and purple charm — all in one box.
The standout piece is the cropped jacket in electric yellow with digitally printed graphics, bold text patches on the sleeves, and a spiked detail on the right shoulder. The jacket comes permanently attached to a white mock turtleneck underlayer for that authentic layered streetwear look — no fussing with separate pieces. Hot pink shorts feature colour-blocked stripes and decorative printed belt details. Black compression leg sleeves add the finishing athletic touch with vertical pink and green accents.
Perfect For
Book Week & Anime Character Days: A natural choice for schools celebrating graphic novels, anime, or action-adventure character parades. Pair with black boots and a purple wig (sold separately) for the full Rumi look.
Cosplay Conventions & Anime Events: Perfect for anime cons, K-Pop fan meetups, or any event where your child wants to channel their favourite demon-hunting hero. The vibrant colours and detailed graphics make this costume instantly recognisable.
Halloween & Costume Parties: Great for Halloween trick-or-treating, themed birthday parties, or dress-up playdates. The comfortable athletic cut means your child can move freely — running, jumping, and play-fighting with ease.
How to Wear It
Pair with black combat boots or chunky trainers to complete the streetwear aesthetic. Add a purple wig styled in a high top knot with long ponytail (sold separately) for the character's signature hairstyle. The silver-toned chain necklace with circular pendant is included in the costume.
Parent FAQs
Q: What size should I order for my child?
Check the size chart image — this costume uses standard kids' sizing based on height and chest measurement. If your child is between sizes, we'd recommend sizing up for a more comfortable fit through the athletic shorts and leg sleeves.
Q: Is the wig included, or do I need to buy it separately?
The wig is sold separately. The costume includes the jacket, shorts, leg sleeves, and charm accessory — everything except the purple wig shown in the photos and the black boots.
Q: Can they wear this for active play, or is it just for photos?
Absolutely suitable for active wear. The stretch knit fabric, elastic waistband, and compression leg sleeves are designed for movement — perfect for running around at a convention or playing at a birthday party.
Q: How do I wash this costume? Will the printed graphics fade?
The graphics are heat-transferred or sublimation-printed, which holds up better than iron-on patches. Hand wash in cold water and line dry to keep the colours vibrant. Avoid the dryer to protect the printed details.
Care: Hand wash cold, line dry. Avoid tumble drying to protect graphics.
