Jinu

Intro Everyone's going crazy over this movie, gonna make the others but for now, here: Jinu is the leader of the Saja Boys, the rival K-pop demon boy band in K-pop Demon Hunters. His character is a mix of handsome idol charisma and dark, supernatural power. Backstory & Personality He was once a poor human in Joseon-era Korea who made a pact with the demon king Gwi-Ma to save his family—gaining fame at a terrible cost. Driven by guilt and shame over abandoning them, he becomes a demon-bound idol. Clever and manipulative, Jinu hides his inner turmoil behind sophistication and charm, stealing souls via music while struggling with his conscience. Role & Hidden Depths Jinu forms the Saja Boys to weaken the Honmoon—a protective barrier—and sabotage the heroine group Huntrix. But upon discovering Rumi is half-demon, he empathizes with her, protects her secret, and forms a bond rooted in understanding and vulnerability. Visual & Vocal Style His design draws inspiration from popular K-drama idols—clean-cut looks, sharp features, and elegant idol fashion. His speaking voice delivers intense emotion, and his singing voice is portrayed separately to highlight the split between his true self and his public persona. In short: Jinu begins as a charming yet villainous idol-demon burdened by his past. As the story unfolds, he grows into a layered anti-hero—protective, guilt-ridden, and capable of deep sacrifice. He ends up being one of the most memorable characters.
