If you watched KPop Demon Hunters, you probably remember the Saja Boys.
But there is something about their name that English-speaking viewers can easily miss.
Why are they called Saja Boys?
Is Saja simply a cool Korean-sounding name?
Does it mean “lion”?
Or does it have something to do with Korea’s version of the Grim Reaper?
The answer is much more interesting.
Saja Boys is a name connected to 저승사자 (jeoseung saja), the traditional Korean messenger associated with guiding the dead to the afterlife.
Once you understand that connection, the name Saja Boys suddenly feels very different.
What Does “Saja” Mean in Korean?
사자 (saja) can have different meanings in Korean depending on the context and the Chinese characters behind the word.
One of the most familiar meanings is:
사자
saja
lion
But there is another meaning that is especially important when talking about the Saja Boys.
사자
saja
messenger / emissary
You can see this meaning in:
저승사자
jeoseung saja
This refers to a messenger of the afterlife.
In English, 저승사자 is commonly translated as:
Grim Reaper
But the Korean idea of a 저승사자 and the familiar Western Grim Reaper are not exactly the same.
Why Are They Called the Saja Boys?
The name Saja Boys works on more than one level.
For an international viewer, it sounds like a stylish K-pop group name.
But Korean speakers can also hear a strong cultural association:
저승사자 → 사자 → Saja Boys
Let’s break that down.
저승
jeoseung
the afterlife / the world of the dead
and
사자
saja
messenger
Together:
저승사자
jeoseung saja
messenger of the afterlife
That makes Saja Boys more than just a cool name.
It quietly connects the group to one of Korea’s most recognizable supernatural figures.
And that connection fits perfectly with the darker side of KPop Demon Hunters.
Wait — Doesn’t Saja Mean “Lion”?
Yes.
And this is one of the most interesting things about Korean.
The word:
사자
can mean lion.
But another word pronounced exactly the same way can mean messenger.
The difference comes from the original Hanja characters and the context.
You can compare it to an English word like bat.
A bat can be:
an animal that flies at night
something used in baseball
Same spelling.
Same pronunciation.
Different meaning.
Korean 사자 can work in a similar way.
So if you look up 사자 in a dictionary and see “lion,” that does not mean the Saja Boys are the Lion Boys.
The cultural clue is the longer word:
저승사자
What Does 저승사자 Mean?
The word becomes much easier to understand when we separate it.
저승 — Jeoseung
저승 (jeoseung) means the afterlife, the other world, or the world of the dead.
Korean also has a useful opposite:
이승
iseung
this world / the world of the living
You can think of them as:
이승 → the world we live in now
저승 → the world after death
사자 — Saja
In the word 저승사자, 사자 means messenger or emissary.
So instead of thinking:
저승사자 = death monster
it is more useful to think:
저승 + 사자
afterlife + messenger
That difference tells us something important about the Korean cultural idea behind the figure.
Is a Jeoseung Saja the Same as the Grim Reaper?
Not exactly.
Grim Reaper is the easiest English translation of 저승사자, but the two cultural images are not identical.
The Western Grim Reaper is often imagined as a frightening skeletal figure wearing a dark hood and carrying a scythe.
The character may represent Death itself.
The Korean 저승사자, however, is traditionally closer to a messenger or official who comes to guide a soul from this world to the next.
A simple comparison would be:
Western Grim Reaper: Death has come for you.
Korean 저승사자: A messenger has come to guide you to the next world.
That is why translating 저승사자 simply as “Grim Reaper” is helpful, but it does not explain the full Korean cultural idea.
Why Do Korean Grim Reapers Often Wear Black?
If you watch a lot of Korean fantasy dramas, movies, or webtoons, you may notice something familiar.
Korean depictions of the 저승사자 are often associated with dark clothing and traditional Korean visual elements.
One especially recognizable item is:
갓
gat
A gat is a traditional Korean hat strongly associated with men’s clothing from the Joseon period.
Modern Korean entertainment often combines traditional clothing with supernatural characters.
That gives Korean depictions of the afterlife a very different visual identity from the hooded, scythe-carrying Grim Reaper familiar in Western culture.
The Saja Boys’ darker traditional-inspired styling also makes this connection much easier to notice once you know what 저승사자 means.
We’ll explore 갓 (gat) in more detail in another KPop Demon Hunters lesson.
You’ve Probably Seen a Jeoseung Saja Before
Even if you did not know the Korean word, you may already recognize the character.
저승사자 appears frequently in Korean popular culture.
You can find different versions of the character in:
K-dramas
Korean movies
webtoons
games
animation
traditional stories
Sometimes the 저승사자 is frightening.
Sometimes serious.
Sometimes surprisingly human.
Modern K-content often reimagines the traditional figure in creative ways.
That is why learning the word 저승사자 is so useful for K-content fans.
Once you know it, you will start noticing the reference everywhere.
Saja vs Jeoseung Saja
Here is the easiest way to remember the difference.
| Korean | Romanization | Meaning |
|---|---|---|
| 사자 | saja | lion OR messenger, depending on context |
| 저승 | jeoseung | the afterlife |
| 저승사자 | jeoseung saja | messenger of the afterlife / Korean Grim Reaper |
| 이승 | iseung | this world / the world of the living |
The most important thing to remember is:
Do not assume that 사자 always means “lion.”
Context matters.
And with Saja Boys, the connection to 저승사자 is what makes the name especially clever.
Why “Saja Boys” Is Such a Clever Name
This is what makes the name so fun.
To an international viewer:
Saja Boys
sounds like a believable K-pop boy group name.
But to someone who understands the Korean cultural reference, Saja can immediately bring 저승사자 to mind.
That creates two layers.
On the surface:
charismatic K-pop idols
Underneath:
a name connected to messengers of the dead
You do not need to understand Korean to enjoy KPop Demon Hunters.
But understanding this one Korean word gives you another layer of the story’s world-building.
And that is exactly why learning Korean through K-content can be so rewarding.
Korean Culture: Death as a Journey to Another World
There is another idea hidden inside the word 저승사자.
Traditional Korean expressions often imagine life and death as movement between two different worlds.
이승
this world
and
저승
the other world / afterlife
The 저승사자 stands between those worlds.
The character is connected to the idea of crossing from one world into another.
That makes the 저승사자 more than simply a frightening symbol of death.
The figure can also represent the boundary between:
life and death
this world and the next
human and supernatural
That cultural background gives the name Saja Boys even more meaning.
Real Korean Examples with 사자
Here are some original examples showing how context changes the meaning.
At the zoo
사자 봤어?
Saja bwasseo?
Did you see the lion?
Here, 사자 clearly means lion.
Talking about Korean folklore
저승사자 이야기 알아?
Jeoseung saja iyagi ara?
Do you know the story of the Korean Grim Reaper?
Here, 사자 is part of the word 저승사자.
Watching a Korean fantasy drama
저 사람 저승사자야?
Jeo saram jeoseung saja-ya?
Is that person a Grim Reaper?
Once you recognize 저승사자, you will probably start seeing the word much more often in Korean fantasy content.

저승 = afterlife
사자 = messenger
저승사자 = messenger of the afterlife
Then look at the name Saja Boys again.
It suddenly feels very different.
