The Saja Boys from KPop Demon Hunters didn’t just capture the hearts of fans on screen - they also enchanted millions in real life. Clearly, demons and charismatic demon singers are a perfect match.
Which begs the question: could this phenomenon also apply to some of anime’s most iconic faces? We’ve put together our very own demonic idol boy band, whose members have already achieved cult status.
Sebastian Michaelis - Black Butler

Every K-Pop band needs a leader - someone who guides the group and takes the spotlight in public. The best fit for this role is the most sensible and mature member, and no one embodies that better than Sebastian Michaelis from Black Butler. As a demon with centuries of experience, Sebastian never loses his cool, even in chaotic moments - exactly the quality you want in a K-Pop leader when scandals, social media storms, or hectic tour schedules hit.
The elegant butler from the Victorian era is meticulous and refined, which helps him keep track of all the band’s responsibilities. Since he doesn’t need sleep, he never wastes a moment that could be spent on the group’s growth. Whether it’s keeping the outfits perfectly pressed, ensuring the choreography is flawless, or signing contracts on time, Sebastian would handle it all effortlessly, impressing even the toughest manager.
His calm and polite demeanor is perfect for public speeches at award shows, and he gets extra points for being multilingual, speaking languages including German and French.
Howl - Howl’s Moving Castle

Almost as important as the leader is the Main Vocal. Of course, a flawless singing voice is essential, but appearance also plays a key role. Howl from Ghibli’s Howl’s Moving Castle has what it takes to be both Main Vocal and Visual. Someone who arrives in a walking, wandering Manor clearly knows a thing or two about putting on a show.
Howl is young, strikingly handsome, and possesses an extravagant style that immediately captivates everyone in the room. As a wizard, he knows how to use magic to enchant fans and could effortlessly charm female admirers. He is also highly emotional and capable of conveying feelings with intensity. He balances glamour, drama, and romance, while remaining a bit unpredictable - the perfect combination for a captivating Main Vocal.
Hiei “Evil Eye” Jaganshi - Yu Yu Hakusho

Not everyone in a K-Pop group can be a charming heartthrob - you also need a proper bad boy to captivate every fan. Hiei “Evil Eye” Jaganshi from Yu Yu Hakusho perfectly embodies this vibe.
He’s a small, rebellious demon with a cool and distant personality. Fans love the “difficult type” who remains mysterious and reveals his feelings only slowly. While he may be quiet in everyday life, as the Main Rapper he could spit some hard-hitting lines. During dance breaks, his fast, precise movements convey power and confidence. Even though he’s small, he exudes danger and dominance, which makes him incredibly compelling on stage. His Jagan Eye only adds to the spectacle and mystery of his performances.
Sesshōmaru - Inuyasha

Also mysterious, but in a completely different way, is Inuyasha’s Sesshōmaru. With his calm demeanor and elegant appearance, he serves as another Visual who makes fans weak in the knees. He doesn’t give off a bad boy vibe; instead, his flawless looks and proud posture make him seem almost otherworldly. His serene aura balances the group’s energy without him having to do much at all. While he is initially very aloof toward humans in the series, he gradually grows into a more empathetic demon - someone who, as an idol, would likely care deeply about his true fans.
Unlike Howl, Sesshōmaru rarely shows emotion - he is the type who generates tension and draws attention without saying a word. On stage, he appears like a living work of art: majestic, composed, and striking. His movements, whether during performances or visual segments, are elegant and controlled, making him perfect for visual highlights and photo moments.
Rin “Son of Satan” Okumura - Ao no Exorcist

In a K-Pop group, the Maknae is the youngest member, often the “baby” of the group with the most youthful appearance. Rin “Son of Satan” Okumura from Ao no Exorcist embodies this youthfulness not only in his name but also in his warm and energetic personality. Rin is impulsive, sometimes reckless, and has a mischievous sense of humor. His open and approachable nature makes it easy for him to connect with fans - he’s the member who hands out autographs with a smile and instantly wins hearts at fan meetings.
With his speed and explosive abilities, he is perfectly suited to be the Main Dancer, bringing acrobatic choreography to the stage. The blue flames he can summon add a spectacular, dramatic flair to his performances, making every show unforgettable.
Doma - Demon Slayer

Our final pick is a reminder that beneath all the charismatic facades of our idol group, dark demons still lurk. Doma from Demon Slayer is one of the Upper-Rank demons - charming, outgoing, and at first glance almost innocent. But behind his perpetual smile lies a cold, manipulative nature. It’s this mix of friendliness and danger that makes him so captivating.
His slightly playful and open demeanor immediately draws fans in, even if he secretly looks down on them. As a Sub Vocal, Doma could shine vocally without overshadowing the leads, while filling the stage with charm. He is able to read the crowd and weave them into the performance - perfect for a Sub Vocal whose role is to support the leads and dancers while keeping the energy high.
