The Saja boy names belong to the five members of the fictional demon boy band in Netflix’s KPop Demon Hunters: Jinu, Mystery, Abby, Romance and Baby. Jinu is the leader and main vocalist, Abby is the main dancer, and Baby is the youngest member. The group’s name, Saja, means “lion” in Korean.
This guide covers saja boy names each member, the meaning behind the group’s name, the voices and singers behind the characters, and a section for parents who want real boy names that start with Saja. It also avoids major plot spoilers.
Saja Boy Names at a Glance
Here is a quick table of saja boy names before the detailed profiles. Roles come from press coverage of the film, and some members have fewer public details than others.
| Name | Role or label | Quick note |
| Jinu | Leader and main vocalist | The only name that sounds like an ordinary Korean given name |
| Mystery | Member | Described by fans as the most mysterious of the five |
| Abby | Main dancer | Nicknamed Abs and drawn with a more muscular build |
| Romance | Member | A plain English word that suits the charming idol image |
| Baby | Youngest member (maknae) | Stage name reflects his place as the youngest |
These five saja boy names are the only members of the group. Some websites list extra “real names” or hidden identities for them, but no confirmed official source backs those lists.
Where the Saja Boy Names Come From
The Saja Boys Names are a fictional five-member Korean boy band created for KPop Demon Hunters, an animated film from Sony Pictures Animation. It reached Netflix on June 20, 2025, and was directed by Maggie Kang and Chris Appelhans.
In the story, the band is far more than a pop group. The members of saja boy names are demons who use fame to collect the energy of human fans. They are also rivals of the girl group HUNTR/X, whose members Rumi, Mira and Zoey secretly work as demon hunters.
Behind the plan stands the demon king Gwi-ma, voiced by Lee Byung-hun. The fight centres on an ancient seal called the Honmoon, which the hunters protect and the demons want to break.
That mix of idol life and supernatural conflict is the reason for the group of saja boy names, looks and songs drew so much attention. The Saja boy names are short and easy to remember, which helps fans talk about the characters.

What Does “Saja” Mean?
In Korean, 사자 (saja) means “lion”. The animal stands for strength, pride and confidence, which suits a boy band built to look bold and powerful on stage.
There is also a darker reading. Depending on the Chinese characters (Hanja) used, the same sound can point to a messenger of death, often described in English as a grim reaper. Fans and entertainment writers noticed this double meaning because the Saja Boys are secretly demons.
So, the group of saja boy names works on two levels:
- Lion: the public image of the band, confident and powerful.
- Messenger of death: the hidden demon identity behind the idol look.
Whether every detail was planned or not, the double meaning fits the story neatly. It is also a good reminder that Saja boy names is the name of the group, not the first name of any member.
K-Pop Terms That Explain the Roles
A few K-pop words appear in almost every discussion of the group. If you are new to the genre, this short list will make the profiles easier to follow.
- Leader: the member who guides the group and often speaks for it in interviews and on stage.
- Main vocalist: the singer who takes the biggest or most demanding vocal parts.
- Main dancer: the member who is strongest in choreography and often sets the standard for the group’s moves.
- Maknae: the youngest member, usually the one fans see as playful or fresh.
In the Saja Boys, these roles are easy to spot: Jinu is the leader and main vocalist, Abby is the main dancer and Baby is the maknae.
Meet Each of the Saja Boys
Every member has a different look and role. Here is what is publicly known about each of the five Saja boy names, without major spoilers.
Jinu: The Leader and Main Vocalist
Jinu leads the group of saja boy names and carries most of the main vocal parts. He is the face of the band on stage and one of the most discussed characters in the film.
His name stands apart from the others. Mystery, Abby, Romance and Baby sound like English stage names, while Jinu sounds like a regular Korean given name, written 지누 in Hangul. No official explanation of the name was found in the sources reviewed, and the meaning of a Korean name depends on the characters used to write it.
Press reports credit actor Ahn Hyo-seop for his speaking voice. His singing voice comes from Andrew Choi, a singer and composer signed to SM Entertainment.
Jinu’s personal story is a major part of the film, so this guide leaves the details out. If you want to avoid spoilers, that is the best way to meet him for the first time.
Mystery: The Quiet One
Mystery is the member fans often describe as the most mysterious of the group. His stage name fits that image. In English, a mystery is something unknown or unexplained, and the character is presented in a way that matches it.
Public information about him is limited compared with Jinu, which suits the name. Most of what people say about him comes from how he looks and carries himself on stage.
As a real-life name, Mystery would be unusual almost anywhere. It works better as a character name than a name for a child.
Abby: The Main Dancer
Abby is the main dancer of the Saja Boys and is also called Abs. The nickname points to his build. According to press coverage of director Maggie Kang’s comments, the team made him about 20 percent bulkier than the other members to stress his physical strength.
Outside the film, Abby is usually a short form of Abigail, a name of Hebrew origin commonly explained as “my father is joy”. In many English-speaking countries it is used mostly for girls, so the Saja Boys version is an interesting twist.
His singing voice is credited to the artist NECKWAV in press reports.
Romance: The Charming Idol
Romance is another of the five idols. His name is a plain English word linked to love and charm, which matches the polished, heartthrob image of a K-pop boy band.
Like Mystery, he has fewer public details than Jinu or Abby. Most fan discussion about him focuses on his style and how he stands out beside the other four.
Romance is rare as a given name and may lead to questions in daily life. Many fans enjoy it as a character name and stop there.
Baby: The Youngest Member
Baby is the youngest member of the group saja boy names, known in K-pop as the maknae (막내). The word is Korean for the youngest person in a group, and a maknae is often treated as the cute or playful member.
His singing voice is credited to Danny Chung in press reports. The stage name is simple and affectionate, and it shows how K-pop groups often turn a role into a name.
Because the name tells you his position right away, Baby is one of the easiest Saja boy names to remember.

How to Remember Who Is Who
If you keep mixing up the five members, these quick cues can help:
- Jinu: the leader and the one whose name sounds like a normal Korean name.
- Baby: the youngest, so his name matches his position.
- Abby: the main dancer with the strongest build, also called Abs.
- Mystery: the quiet, hard-to-read member.
- Romance: the smooth, charming idol of the group.
Remember that Saja is the group name of saja boy names When someone says, “the Saja Boys”, they mean all five together.
Voice Cast and Singers
Animated musicals often use one person for speaking and another for singing, and that is the case here. The table below lists the credits reported in the press.
| Member | Credited voice or singer (press reports) |
| Jinu | Ahn Hyo-seop (speaking voice) and Andrew Choi (singing voice) |
| Abby | NECKWAV (singing voice) |
| Baby | Danny Chung (singing voice) |
| Mystery | Not confirmed here. Check the official film credits |
| Romance | Not confirmed here. Check the official film credits |
Credits can change between sources, so use the official film credits when you need exact names for a post or a caption.
Songs Linked to the Saja Boys
Two songs are most often linked with the group: “Soda Pop” and “Your Idol”. Both gained attention for strong vocals and a polished sound that matches the idol image the band is built on.
The songs also say something about the band’s personality. They sound bright and friendly on the surface, while the story underneath is about demons collecting human energy.
If you are new to the film, listening to these two tracks is an easy way to get a feel for the group before you watch.
Saja Boys vs HUNTR/X
The two groups are often mixed up in searches, especially because both appear in the same story. This table keeps them apart.
| Group | Members | Role in the story |
| Saja Boys | Jinu, Mystery, Abby, Romance, Baby | Demon idols and rivals |
| HUNTR/X | Rumi, Mira, Zoey | Idols who are secretly demon hunters |
Why the Saja Boys Use Simple English Stage Names
Four of the five saja boy names are everyday English words or nicknames: Mystery, Abby, Romance and Baby. Only Jinu sounds like a typical Korean given name.
The makers have not explained this choice in the sources reviewed for this guide. A likely reason is that short English words are easy for fans around the world to say and remember, which fits global K-pop branding. Treat that as a reasonable explanation, not an official one.
There is another effect too. Names that describe a role or a feeling make the characters easy to tell apart at a glance. You can guess a lot about Baby or Mystery before they say a word.
Common Mix-Ups About the Saja Boy Names
Because the film is so popular, some wrong ideas spread quickly. These saja boy names are the ones worth clearing up:
- Not a real group: the saja boy names are fictional, although real singers provide their voices.
- No confirmed real names: some websites invent birth names or secret identities for the five members. Do not treat those as official.
- Saja is not a first name here: it is the name of the band.
- Five members only: the group has five members, not more.
- Inspiration is not copying: press coverage says Maggie Kang named groups such as BTS, TXT, ATEEZ, Stray Kids, BIGBANG and MONSTA X as visual influences. That is inspiration, and there is no confirmed proof that the member names come from real idols.
Can You Use Saja Boy Names for a Real Baby?
Many people who search for Saja boy names are fans thinking about a baby name. It is a fair question, and the honest answer is that some of these names work better than others.
- Jinu: the easiest to use. It is short, has two syllables and is simple to say in English. Ask a Korean speaker about the meaning, because it depends on the characters chosen.
- Abby: familiar and friendly, but usually a girls’ name in English-speaking countries. A boy named Abby may often be asked to explain it.
- Baby, Mystery and Romance: these are better as nicknames or character names. As legal names they can invite teasing or constant questions.
A good test is to say the full name with the surname and picture it on a school register and later on a job application. If it still sounds right, it is a safe choice.

Real Boy Names That Start with Saja
Some searchers are not looking for the film at all. They want real boy names that begin with Saja. The list is short, but a few names with the same sound are in genuine use across Arabic and South Asian cultures.
| Name | Widely given meaning | Origin | Notes |
| Saja | Calm, stillness | Arabic | Mostly a girls’ name; some sources give “fortune” or “success” |
| Sajan | Beloved, dear one | Sanskrit and Hindi | Used for boys; one source also lists “appear” or “become” in Sanskrit |
| Sajjan | Noble, gentleman, good person | Sanskrit and Indian | Used for boys |
| Sajjad | One who bows or prostrates in prayer | Arabic | Also spelled Sajad; common among Muslim families |
| Sajid | One who prostrates or worships | Arabic | Shares a root with Sajjad |
Spellings change by region, so you may see Sajad and Sajjad for the same name. Pick one spelling and use it the same way on every official document.
Meanings also differ between sources. Before you finalize a name, confirm the meaning with a native speaker or a trusted lexicon.
