Jinu is the charismatic leader of the Saja Boys, the K-pop boy band that is secretly a front for demons serving the evil force Gwi‑Ma. Once a human in Korea’s Joseon era, Jinu sold his soul to gain fame and fortune. Now his mission is to defeat the heroic girl group HUNTR/X. He blends heartthrob charm with dark deviousness, hiding his true nature behind the glitzy veneer of pop stardom.
Even if you’ve watched KPop Demon Hunters more times than you can count — and legions of fans have — there’s always more to learn about your favorite emotionally complex demon. Read on for everything you need to know.
Name: Jinu

Gwi-Ma: The manipulative demon overlord who owns Jinu’s soul

Saja Boys: His bandmates and fellow demon idols
Jinu begins as a symbol of everything Rumi fights against, but his arrogance masks a deep guilt over the family he left behind. Haunted by what he sacrificed, he begins to question Gwi-Ma’s control, and in the film’s final act, he redeems himself by defying the demons and helping Rumi seal the honmoon gate between worlds. His story ends not with triumph, but with tragic grace — a fallen star choosing light one last time.
“Woah, mind the face — I need it to steal your fans.” (32:10) — said jokingly, when Rumi almost slices his face up with her sword.
“That’s all demons do — feel. Feel our shame. Our misery. It’s how Gwi-Ma controls us.” (39:45) — said when he and Rumi confront each other away from battle.
“I left my sister, my mother, alone, while I slept in silk sheets in the palace, with my belly full every night.” (1:10:00) — said when he finally tells Rumi the truth about his past.
“You gave me my soul back … and now, I give it to you.” (1:22:01) — said when he sacrifices everything to help Rumi defeat Gwi-Ma.
