Character Overview

Rumi is the leader and lead vocalist of HUNTR/X, the K-pop trio at the centre of KPop Demon Hunters. Alongside Mira and Zoey, she balances life as a celebrated performer with the group’s supernatural mission to defend the human world from demons.

Her “How It’s Done” outfit appears during one of HUNTR/X’s defining performance sequences. The bright jacket, cropped top, contrasting shorts and stage accessories create a distinctive silhouette that is immediately recognisable to fans of the film.
