You’ve heard of BTS. You know BLACKPINK. But have you met the Saja Boys? These animated “villains” in Netflix’s “KPop Demon Hunters” aren’t just cartoon characters, they’re the highest charting male K-pop group in US Spotify history, surpassing even BTS. And their business impact is rewriting entertainment rules. Let’s dive into how fictional demons became real gold.
The Fictional K-Pop Demons Saja Boys to Become a Real KPop Group

“KPop Demon Hunters,” which proves that authentic cultural exchange creates real magic, as it became Netflix’s most-watched film ever! It’s not just a film; it’s a community, a cultural bridge, and a business model.
The film grossed an incredible $20 million from sing-along screenings alone. Its success is a phenomenon. Fans started treating the fictional idols in the movie like they were real. It’s amazing to see how deeply people connect with these characters!
The fictional demon boy band in “KPop Demon Hunters,” Saja Boys, has officially registered with Korea’s music rights organization. These five fictional idols aren’t just an animation anymore; they’re becoming a real K-pop idol group. With official music performer status in Korea, they’re stepping out into your concert venues.
Saja Boys: Villains Who Stole Hearts Worldwide
The Saja Boys aren’t just animated villains. They’re cultural mirrors. This five-member boy group (Jinu, Abby, Romance, Mystery, and Baby) represents real issues in the K-pop industry. Each member embodies different challenges faced by real idols.
Baby shows the infantilization of Asian idols. Abby symbolizes sexualization. Romance delivers parasocial fan relationships. Mystery represents a lack of privacy. Jinu embodies selling your soul to the industry.
As director Maggie Kang explained, “We wanted characters that felt real, even as demons.” This authenticity resonates globally. The Saja Boys became “Netflix’s most discussed fictional group” according to Meltwater data.

The “Soda Pop” performance by Saja Boys became the most-watched scene in “KPop Demon Hunters.” Fans particularly loved:
- Jinu brushes off his shoulder at Rumi.
- Abby Saja’s shirt lifts, revealing her abs.
- The boys are making hearts out of thin air.
From Animated Characters to Billboard Chart-Toppers

The Saja Boys weren’t supposed to be the stars. They were created as the demon-rival group to HUNTR/X in “KPop Demon Hunters.” However, they’re too hot to hate; they stole hearts and charts fast.
You’ve probably seen the evidence: fan art, dance covers, and even real-life fashion inspired by their looks. Their song “Your Idol” helped them top the US Spotify chart alongside HUNTR/X’s “Golden.” This wasn’t just animation; it was a real music-industry success.
According to reports, the Saja Boys became “the highest charting male K-pop group in US Spotify history.” Their soundtrack peaked at #2 on Billboard 200 with eight songs landing on the Hot 100. Not just fictional characters; they’re legitimate chart competitors.
The Paper Trail That Proves It’s Real
According to the Federation of Korean Music Performers (FKMP), all five Saja Boys vocalists — Andrew Choi, Neckwav, Kevin Woo, Danny Chung, and samUIL Lee — registered as official members, crossing a legal threshold no fictional group has breached before. This isn’t fan fiction. This is paperwork.
FKMP (Federation of Korean Music Performers) manages rights for over 50,000 performers. Their membership means Saja Boys now qualify for performance royalties in Korea.
As Cho Hyun from FKMP explained: “In a time when K-pop content is spreading worldwide, it is meaningful that artists active mainly overseas have voluntarily joined FKMP.”
Can you imagine your favorite animated character suddenly becoming eligible for music awards? That’s exactly what’s happening here.
Meet the Humans Behind the Demons

The actual singers who voiced the Saja Boys aren’t voice actors playing musicians. They’re industry veterans who’ve been working behind the scenes for years. Their FKMP registration confirms what fans suspected: they aren’t temporary characters. They’re building careers.
Andrew Choi is the singing voice for Jinu (already an FKMP member). He’s a well-known producer in the Korean music industry, having worked with groups such as SHINee, EXO, and NCT.
Neckwav is the singing voice for Abby/Abs Saja (already an FKMP member). He’s a vocalist and producer who has released independent music on platforms like Spotify.
Kevin Woo is the singing voice for Mystery Saja (already an FKMP member). He made his debut in 2008 as a member of the K-pop group U-KISS. He has pursued a solo career and hosted variety programs after leaving U-KISS.
Danny Chung is the singing voice for Baby Saja (new FKMP member). He’s a singer-songwriter who has worked with artists like Somi, BLACKPINK, and others.
samUIL Lee is the singing voice for Romance Saja (new FKMP member). He helps make music for SEVENTEEN.
Now, when you stream “Soda Pop,” with 92+ million YouTube views, you’re supporting real artists with real careers. That changes everything.
Beyond the Screen: The Real-World Impact of Fictional Idols
“KPop Demon Hunters” is so much more than just watching animation. From its huge success, previously, you might have wondered: Could fictional K-pop groups debut as real artists? Now, we can see the answer is a big YES. HUNTR/X did it first.
The film presents HUNTR/X as a real pop group, fostering authentic fan connections. Then, EJAE, Audrey Nuna, and Rei Ami transitioned from their roles as Rumi, Zoey, and Mira to become real performers.
Watch their stunning performance on Jimmy Fallon below.
HUNTR/X has set a new standard. Now, the Saja Boys singers’ FKMP registration allows fictional idols to become real-life artists with careers that last beyond their original stories.
The success of both HUNTR/X and Saja Boys demonstrates that this isn’t just entertainment, it’s a new cultural ecosystem. It shows how music, animation, and fan culture can merge into something greater. The film’s message about music’s power to bridge cultures isn’t just narrative; it’s a business reality rooted in soft power.
The upcoming MAMA Awards performance will be the ultimate test. Can animated demons turn into a real Kpop group and take a real stage? We’ll find out soon.
