1. Who are the Sajja Boys?

 

The Saja Boys, who appear in "KPOP Demon Hunters," are a charming K-POP boy band on the surface. However, their true identity is that they are "messengers of hell" controlled by the demon king, Gwima.

 

A sparkling idol by day, a soul-hunting demon by night - viewers are in a frenzy over this contrast. Through concerts, she absorbs the "emotional energy" of her fans, and plots to destroy the "Honmoon" that separates the human world from the demon world.

They then find themselves facing a fateful showdown with the K-pop girl group "Huntrix," led by the main character Rumi.

 

 

 

 

2. Member profiles and voice actors/singing cast list

Saja Boys is an original K-POP unit made up of five members. Each member has a unique personality, and the voice and singing cast is super luxurious!

 

name	Features	Voice actor (English version)	Singing Cast
Jinu	A charismatic leader and a tragic fallen angel	Ahn Hyo-seop	Andrew Choi
Abby	Muscular performer, outgoing person	Cho Seung-won	Neckwav (rapper)
Baby	Beautiful boy type/low-pitched rapper	-(Details unknown)	Danny Chung (composer)
Mystery	Cool type with face hidden	Alan Lee	Kevin Woo (formerly of U-KISS)
Romance	Sweet smiling prince character	Joel Kim Booster	samUIL Lee (Producer)

 

 

In particular, the pairing of Ahn Hyo-seop, who played Jinu, and Andrew Choi, who sang the role, has been talked about as "divine casting" among fans!

 

 

 

3. Who is the real-life model? A thorough analysis of the influence of idols and actors

 

The character settings and visuals are heavily inspired by real-life K-POP stars.

 

▪️Jinwoo

 

 

In addition to his "prince-like visuals" similar to Cha Eun-woo and Nam Joo-hyuk, he is also known for his anguished and shadowy facial expression.

 

 

▪️Baby

 

 

Reflecting BTS Jimin's staging and posing. A cute gap between an innocent appearance and a powerful rap.

 

 

▪️ Entire group

 

 

A mix of K-POP essence across generations, including TXT, Stray Kids, ATEEZ, BIGBANG, MONSTA X, etc.

 

 

According to the production team, "Rather than using a single model, we created the character by combining elements from multiple people." This is why the character feels "realistic" even though it is "fictional."

 

 

 

 

4. The rapid advance of the song "Your Idol" and its OST! Behind the scenes of its chart-topping on Spotify

The song "Your Idol" performed in the drama was an unprecedented hit, making it into the Top 10 on the real-life Spotify K-POP chart!

 

🎶Produced by K-POP heavyweights such as TEDDY and KUSH

🎶"Takedown" sung by TWICE's Jeongyeon, Jihyo and Chaeyoung will be the main theme of the movie

🎶Huntrix's "Golden" and Saja Boys' "Soda Pop" are also highly addictive!

 

Just like real K-POP, the sound is extremely refined, and the appeal of this work is that it can be enjoyed as music on its own.

 

 

 

 

5. Behind the scenes of character settings from the production team

 

Director Megi Kang commented that she thoroughly researched and reflected the reality of the Korean K-pop industry, including "autograph signing culture," "cheering slogans," and "airport fashion."

 

In addition, the film is full of respect for Korean culture, with kimbap, samgyetang, traditional clothing, hanok, folk paintings, and more, and even though it is a foreign animation, it has a strong Korean feel to it. In particular, the scene where Abby signs the abs and the depiction of Baby snatching the cheering towel are typical scenes that will make any K-POP fan smile.

 

 

 

 

6. Hints of his reappearance in the sequel? Jinu's "disappearance" and the mystery of the mascot

At the end of the movie, Jinu disappears while protecting Rumi, which is a touching development. However, the following elements appear in the post-credits scene:

 

💡The Saja Boys mascot doll glows red

💡The background is near Namsan Tower in Seoul

💡A creepy laugh accompanied by the caption "Honmoon is still open"

 

This is seen as a definite hint at Season 2, suggesting Jinu's return and the emergence of a new enemy!

 

 

 

 

7. Fans talk about memorable scenes and the secret behind its popularity

✔️On social media, the following scene was highly praised as a “divine performance”:

 

👤 Rumi vs Jinu showdown: The ice and fire-like performance is being called "Frozen x Spider-verse"

👤Mira's aerial battle: Beautiful animation on par with wire action

👤 "I want my soul to be stolen by the Saja Boys" phenomenon: Some fans are so charmed that they post, "I'm glad my favorite is my enemy"

 

 

It also ranked highly on Netflix's global rankings, quickly gaining an overseas fan base.

 

 

 

 

8. Summary: Are the Saja Boys the enemy or just another protagonist?

The Saja Boys are not just "enemy characters." Each of them has a background and emotions, and characters like Jinu, who carries the pain and hopes of his time as a human, have been particularly relatable to viewers.

 

 

How will they reappear in the sequel, and how will their relationship with Rumi progress? The term "Sajabo-pen (= Saja Boys fan)" has already been coined, and attention is focused on their future developments!
