What is the name of the rival boy band in KPop Demon Hunters?

The Saja Boys are the rival boy band in KPop Demon Hunters.

They appear to be a glamorous K-pop group competing with HUNTR/X, but the members are secretly demons. Their performances are part of a supernatural plan connected to Gwi-Ma, the ruler of the demons.

The name refers to the Korean term jeoseung saja, traditionally associated with a grim-reaper-like figure who guides souls to the afterlife. The film uses that cultural idea in the group’s visual identity, including black hanbok-inspired clothing and traditional horsehair hats.

The Saja Boys are led by Jinu. Their role is more than ordinary musical rivalry: their songs and popularity help advance the demons’ attempt to weaken the barrier protecting the human world.
