K-POP DEMON HUNTER - Rumi Sain-Geom Premium Electronic Sword 101cm

Wield Rumi’s iconic weapon with this premium electronic replica of the Sain-Geom, inspired by the Netflix animated film *K-Pop Demon Hunters*. Measuring approximately 101 cm in length, this collectable sword combines detailed sculpting, advanced lighting effects and sounds taken from the film’s universe. It is designed for cosplay and role-play as well as for display within a collection dedicated to HUNTR/X.

The replica captures the elegant lines of the weapon used by Rumi, with a blade adorned with finely engraved demonic motifs and metallic finishes that enhance its fantastical appearance. Over 50 LEDs are distributed throughout the sword to produce dynamic light animations and various colour combinations.

Four electronic modes allow the experience to be tailored to the intended use. Combat mode reacts to the sword’s movements with sounds and lights inspired by the film. Rainbow Swing FX mode generates multicoloured effects when the user swings the weapon or dances with it. In Music Recognition mode, the sword analyses a song or a voice and synchronises its lights with the beat, with certain K-pop tracks by Demon Hunters triggering special sequences. Finally, Display mode allows you to select a fixed colour or activate a concert-style light show.

The Sain-Geom is powered by a rechargeable battery built into the handle. For extended lighting display, it can also be powered via its side-mounted USB-C port; the cable is not included. A transparent purple stand featuring the HUNTR/X logo is included so that the sword can be displayed horizontally on a shelf or in a display case.

Origin and lore of the weapon

Rumi is the lead singer of HUNTR/X, a famous K-pop trio also comprising Mira and Zoey. Behind their careers as superstars, the three artists lead a second life as demon hunters and use their songs and spiritual weapons to protect their fans from supernatural forces.

The Sain-Geom is Rumi’s personal weapon. Inspired by the Korean Four Tigers sword, it channels her energy and aids her in her battles against demons. Its refined appearance, luminous patterns and association with music reflect Rumi’s dual identity: leader of HUNTR/X on stage and a warrior tasked with maintaining the mystical barrier known as Honmoon.
