Rumi’s traditional Korean sword is called a saingeom in KPop Demon Hunters.
The saingeom is Rumi’s combat weapon as she fights demons alongside Mira and Zoey. The choice of weapon connects the fictional idol group to Korean martial and cultural imagery, reinforcing the film’s goal of blending contemporary K-pop performance with older Korean traditions.
The three Huntrix members use different traditional-style weapons. Mira carries a gokdo polearm, while Zoey uses shinkal throwing knives. Their distinct weapons help viewers identify the characters during fast-moving action sequences.
Norigae is another Korean cultural term associated with the film, but it refers to a decorative pendant used in costume design rather than Rumi’s sword. The weapon’s canonical name is saingeom.
