SAJA Boys

Five demons put on bubblegum-pink idol disguises, released two songs, stole a stadium full of attention and accidentally became a real chart phenomenon outside their movie. The SAJA Boys are fictional. Their music, performers and fandom impact are not.

Meet the five animated members

Jinu

Leader · lead singer · center

The former human who sold his soul to Gwi-Ma and leads the plan to weaken HUNTR/X. Ahn Hyo-seop provides Jinu’s speaking voice; Andrew Choi performs his singing voice.

Abby

Performance member · muscular visual

The group’s deliberately exaggerated fitness-idol archetype. Neckwav is part of the five-man singing ensemble behind the SAJA Boys.

Mystery

Vocalist · mysterious visual

His face-obscuring blue hair turns idol mystique into a literal character design. Former U-KISS member Kevin Woo supplies his singing voice.

Romance

Vocalist · romantic visual

The long pink hair and heart styling weaponize the soft-boy archetype. Joel Kim Booster supplies his English speaking voice; samUIL Lee is part of the singing ensemble.

Baby

Rapper · maknae

The toddler-cute disguise hides a deep rap voice and a soul-eating demon. Songwriter and THEBLACKLABEL A&R Danny Chung voices and sings Baby.

The real artists behind the songs

Andrew Choi, Neckwav, Danny Chung, Kevin Woo and samUIL Lee perform the SAJA Boys vocals on “Soda Pop” and “Your Idol,” with the KPop Demon Hunters cast also credited. These artists remain individual performers; the SAJA Boys profile is the shared home for the fictional group’s songs.

Two songs, two disguises

“Soda Pop” is the bait: bright, retro, sweet and intentionally “annoyingly addictive.” The choreography and pastel styling sell perfect rookie innocence while the lyrics hide predatory intent.

“Your Idol” removes the mask. The same group becomes dark, ceremonial and openly controlling. Danny Chung described the pair as a deliberate duality: one sinister in secret, the other sinister in plain sight.

Why they count as a group here

CVM Sekai treats virtual idol acts as groups when the story and music present them that way. Jinu, Abby, Mystery, Romance and Baby are the members. Their real singers are credited as artists attached to the songs; they are not substituted for the animated lineup.
