Key details about the film and its central characters are compiled below.

Who is Romance in KPop Demon Hunters?

Romance Saja is one of the most intriguing characters in KPop Demon Hunters precisely because he exists in the space between performance and predation. He’s a demon who masquerades as a K-pop idol within the Saja Boys, the rival boy band that serves as the film’s primary antagonists.

Romance Saja character overview

Romance Saja operates alongside Jinu as part of Saja Boys, a demon group formed specifically to steal fans and weaken Huntrix’s power through influence. According to Out.com’s analysis, the Saja Boys use their idol personas to infiltrate the music world and drain the mystical barrier that protects humans from demon incursions.

• Member of the Saja Boys demon band
• Disguised as K-pop idol to attract and harvest fan devotion
• Stands beside Jinu in the demon realm hierarchy

Role as demon K-Pop idol

The character embodies the film’s central tension between image and reality. While Huntrix wields music as a weapon to slay demons, Romance Saja and his cohorts weaponize fandom itself—turning adoration into a gateway for supernatural corruption.

Who played Romance Saja?

The casting of Romance Saja carries particular significance given who voices him and what that actor represents in terms of representation within the film.

Voice actor details

Joel Kim Booster provides the voice of Romance Saja, with Samuil Lee handling the character’s singing voice. This casting matters: Joel Kim Booster is an openly queer Asian-American actor whose presence in the project highlights the film’s commitment to LGBTQ representation behind the scenes as well as on screen.

• Joel Kim Booster voices Romance Saja (one of three roles he plays in the film)
• Samuil Lee provides Romance Saja’s singing voice
• Joel Kim Booster has described these roles as “very small parts” in interviews

Additional cast notes

The Saja Boys lineup extends beyond Romance Saja: Alan Lee voices Mystery Saja (with Kevin Woo singing), SungWon Cho voices Abby Saja (with Neckwav singing), and Danny Chung voices Baby Saja, according to Wikipedia. On the protagonist side, Ahn Hyo-seop voices Jinu with Andrew Choi as his singing voice, while Yunjin Kim voices Celine with Lea Salonga providing her singing parts.

Why didn’t Jinu and Rumi kiss?

This question has become one of the most-searched queries following the film’s Netflix debut, ranking among the top Google Trends questions according to Out.com. Viewers who expected a conventional romantic resolution found something more ambiguous instead.

Plot context for tension

Rumi, leader of Huntrix, carries a secret that shapes every interaction with Jinu: she is half-demon, born to a human mother and a demon father. Her struggle to close the honmon—a portal between worlds—parallels queer-coded panic and the path toward self-acceptance through connection with someone who understands hidden identities.

• Rumi’s half-demon secret creates tension with her demon-hunter identity
• Jinu, as a demon, represents someone who wouldn’t reject her hidden self
• The film’s emotional climax centers on acceptance rather than romantic consummation

The 90/10 rule reference

The romantic tension between Rumi and Jinu deliberately avoids easy resolution. The film instead explores intimacy through understanding rather than physical affection—a narrative choice that resonated with viewers who found the emotional authenticity more mature than a typical kiss scene would have been.

Is Romance Saja evil?

The answer depends on how you define villainy in a story where the protagonists’ enemies are literally demons. Romance Saja operates as an antagonist, but the film complicates simple moral categories.

Villain background

Romance Saja serves the Saja Boys’ mission: infiltrating human music culture to harvest fan devotion and weaken the barrier that keeps the demon realm in check. By that functional definition, yes—he’s working for the “evil” side in the film’s central conflict.

• Member of demon group formed to steal fans from Huntrix
• Uses idol persona to lure followers toward supernatural corruption
• Operates under Jinu’s leadership within the demon hierarchy

Demon motivations

The film’s universe treats demons as a distinct species rather than evil by nature. Jinu’s backstory—transformed 400 years ago due to guilt over a deal gone wrong—suggests demons in this world are complex beings shaped by choices and circumstances. Romance Saja’s individual motivations remain less explored than Jinu’s, leaving room for future character development if sequels emerge.

Are KPop Demon Hunters LGBTQ?

KPop Demon Hunters doesn’t feature explicitly LGBTQ+ characters in the sense of characters who explicitly identify with a particular queer label. What it does offer is richer and more contested territory: a queer allegory that has sparked debate among viewers and critics since its June 2025 Netflix debut.

Queer allegory elements

Co-director Maggie Kang stated explicitly that Rumi’s story “is like she’s coming out of the closet and coming clean to her parents who want her to be something that she’s not.” This wasn’t spin—it’s baked into the film’s narrative DNA. During development, the team discussed Rumi’s story in terms of mixed heritage, queer identity, addiction, and “hiding parts of oneself described as the ‘demon part,'” according to Wikipedia.

• Rumi’s half-demon secret functions as a metaphor for hidden queer identity
• Her journey from shame to self-acceptance mirrors LGBTQ+ experiences of coming out
• Jinu’s acceptance of her demon side represents the possibility of being loved authentically

Representation in series

Out.com’s coverage notes that while no characters are explicitly LGBTQ+, Rumi’s arc is “heavily queer-coded with religious trauma parallels.” The film also features Joel Kim Booster, an openly queer actor, in a demon role—adding another layer of representation that viewers have interpreted variously as subversive casting, symbolic positioning, or both.

The reception has split along predictable lines. Some viewers map Rumi’s demon side directly to LGBTQ+ secrecy and self-acceptance, finding her arc deeply resonant. Others see the allegory as applicable beyond gender and sexuality entirely, a general framework for anyone who has hidden an essential part of themselves.

Rumi’s story [is] like she’s coming out of the closet and coming clean to her parents who [want] her to be something that she’s not.

We kind of described the demon part of you where someone is hiding part of themselves from others.

I’m romance. I’m one of the titular demons.
