What Happened to Jinu in Kpop Demon Hunters?
In KPop Demon Hunters, Jinu is the leader of the Saja Boys, a boy band secretly working for the underworld demon lord Gwi-Ma. Initially a rival to the girl group Huntrix, Jinu's connection with Rumi—Huntrix's leader—grows deeper, revealing his inner conflict.
Rumi, hiding her identity as half-demon, struggles with self-acceptance, while Jinu is manipulated into nearly betraying her. However, during the film’s climactic battle at the Idol Awards, Gwi-Ma attacks to destroy the world’s spiritual barrier, Honmoon.
At the last moment, Jinu turns against his dark master and sacrifices himself to save Rumi, taking the fatal hit intended for her. His redemption is heartfelt—he tells Rumi that her strength gave him the courage to change.
Jinu’s death becomes a turning point, inspiring Huntrix to rise, restore the barrier, and embrace their true selves. Though Jinu dies, his impact lingers, and the ending leaves open the possibility of his return in a future sequel.

Who Sings for Jinu in KPop Demon Hunters?
While Ahn Hyo-seop provides the speaking voice for Jinu, the movie has not officially confirmed if he also performs Jinu’s singing parts, or if a professional singer filled in. The music team includes a roster of K-pop collaborators and music producers, so it's likely that a trained vocalist lent their voice to Jinu’s tracks.

The film doesn’t give an exact age, but based on his appearance and idol status, Jinu is likely in his late teens to early twenties, similar to most active K-pop idols. His age also fits the romantic tension and emotional growth seen throughout the movie.

KPop Demon Hunters – Jinu and Rumi’s Relationship
One of the emotional cores of the movie is the slow-burning relationship between Jinu and Rumi, the leader of Huntrix. Despite being enemies on the surface, Jinu and Rumi grow close as he begins to question his role in Gwi-Ma’s plan.
Rumi hides the fact that she’s half-demon, and Jinu—also trapped between duty and identity—relates to her inner struggle.
Who Is Rumi’s Dad in KPop Demon Hunters?
In KPop Demon Hunters, Rumi’s biggest secret—and the film’s major twist—is that her father is a demon, making her half-human, half-demon.
