Built for interactive play and display, the KPop Demon Hunters Rumi sword offers four modes with 50+ LEDs and sound effects inspired by the film.

It responds to movement, music and singing, unlocking unique light patterns as you swing and when you listen to official music from the movie.

The lights also match the rhythm of your favorite songs and can react to the sound of your own singing.

A rechargeable battery powers the sword during use, while a USB-C port supports a lit-up shelf display.

Use the clear, purple-tinted stand with the HUNTR/X logo to rest the sword when not in use.

At roughly 40 inches long, it has the scale of a full-size prop, making the $224.99 price tag a little easier to justify.
