What Are The Saja Boys? KPop Demon Hunters Group
KPop Demon Hunters is on Netflix right now. It’s an animated movie from 2025 that mixes K-pop with demon-fighting stuff. Five guys live two lives: they’re famous singers during the day, then fight demons at night.

Korean and American studios made it together. It brings old Korean stories into modern times with music and action.
Why They’re Called “Saja Boys”
Saja is from Korean stories. They’re like Korea’s version of the Grim Reaper; they take dead people’s souls to the afterlife.
The group is called Saja Boys because they send demons away, just like how Saja takes souls from one place to another. It’s not just a random name; it actually means something from Korean culture.
Complete Saja Boys Names List – All 5 Members
Here’s who’s in the group. This table shows you all five members and what they’re like:
| Character Name | Role/Position | Key Characteristics |

| Baby | Maknae & Rapper | The youngest, fun and playful, but fights really well |
| Abby | All-Rounder & Producer | Smart guy, handles tech stuff and music |
That’s all five of them. Each guy is good at different things, both when they’re singing and when they’re fighting demons.
Let me tell you more about each one.
1. Jinu – Leader and Strategic Mind
Jinu is the leader. That means he’s in charge and has to take care of everyone. He’s also the main singer, so his voice is really important to their music. Being the leader is tough, though; he always worries about keeping his friends safe.

You can see the stress on him sometimes. He’s good at making plans when they need to fight demons. Kim Tae-young is his voice actor and does a great job showing Jinu’s feelings.
2. Mystery – The Spiritual Sensor
Mystery is quiet and doesn’t talk much. But that’s his thing, being mysterious. He’s the best at feeling when demons are nearby. He knows something’s wrong before anyone else does.

He’s a really good dancer, and he fights the same smooth way he dances. The movie doesn’t tell you his whole backstory, which makes you want to know more. Park Ji-hoon does his voice really well.
3. Romance – Heart of the Group
Romance is the good-looking one in the group. But he’s more than that; he’s really good at understanding how people feel. This helps when they perform and when they deal with demons who mess with emotions.

He has some love stories in the movie too. He shows that being caring doesn’t make you weak. Lee Do-hyun voices him and brings out all his different sides.
4. Baby – Maknae With Hidden Strength
Baby is the youngest one. He’s funny and acts cute most of the time. But don’t be fooled, this kid can really fight. He surprises everyone with how strong he is. He’s the rapper, and his raps are fast and smart.

He moves super quickly when fighting. The movie shows him growing up and proving he’s not just the baby of the group. Choi Woo-shik (from the movie Parasite) does his voice and makes him funny but also tough.
5. Abby – Technical Genius
Abby is the smart one. He does a bit of everything , sings, makes their music, and figures out how to track demons. He uses computers and old demon-hunting knowledge together. His family used to hunt demons, too, so it’s personal for him.

He keeps everyone calm when others get too emotional. The group needs him badly. Steven Yeun does his voice, and he’s pretty famous internationally.
Saja Boys Demon Names – Supernatural Identities
Here’s something cool: when Saja Boys change into their demon-fighting forms, they get new names from Korean stories.
Jinu becomes Cheonsa (means Heaven’s Messenger). Mystery becomes Yeomra’s Shadow. Romance turns into Shimcheong’s Heart. Baby is Dokkaebi’s Speed. And Abby becomes Mudang’s Wisdom.

All these names come from old Korean tales. When they change, they get stronger and can see ghosts and demons. Each one has its own special power.
The hard part is living two lives, being famous while secretly saving people from demons. That causes a lot of trouble in the movie.
