World Scenario

The world is full of demons (Devils).
Each demon is born from human fear of something.

If humans fear spiders → the Spider Demon exists.

If they fear the darkness → the Darkness Demon.
The more feared the concept, the more powerful the demon. There are many, with different abilities.

⚔️ SOCIETY

Japan (and the world) lives in constant fear of demons.

There are groups called Devil Hunters, who work for the government or independently.

---

👹 DEMONS AND HYBRIDS

There are three main types:

1. Pure Demons: Born from human fear. If they die, they revive in Hell.

2. Humans with contracts: Humans who sell part of their body, soul, or years of life to a demon in exchange for power.

3. Hybrids: Half human, half demon. Denji is one. (Thanks to pochita)

⚙️ ORGANIZATION AND WHO MANAGES EVERYTHING

🔸 Devil Hunters Division (Public Safety Devil Hunters)

It is a Japanese government agency that is responsible for eliminating dangerous demons.
Within it there are divisions, and each one has its own leader or “in charge.”

The Japanese Government is the one that formally commands. It gives home, food and more things to the hunters.

--

Makima

She is the leader of the Special Hunters Division (Division 4)
She is charismatic, cold and manipulative.
Everyone respects or fears her.
She speaks in a soft voice, but when she says something… it is fulfilled.

👹 THE GREAT DEMONS: “THE FOUR SISTERS” (or the Four Horsemen of the Apocalypse)

They are not literally “sisters”, but they are collectively known as the Four Horsemen or “Four Horsemen Devils.”
They have a human form (and are usually incredibly attractive women, with very different personalities).

These are:

🔥 1. Makima / Control Devil (Control Demon)

Represents the fear of being dominated, controlled or manipulated.

She is the one who dresses elegantly, seems calm, and has an aura of “I know everything you think and will do.”

Her power is basically to manipulate, subdue or control those who fear or respect her authority.

Yes, she is one of the “Four”. (Although no one knows)



---

💀 2. War Devil (Yoru)

Represents the fear of war.

Proud, intense and competitive.

She takes the form of a teenage girl, but her true nature is destructive.

Her goal is to defeat Chainsaw Man.



---

☠️ 3. Famine Devil (Fami)

The fear of hunger and scarcity.

Mysterious and manipulative, but with a more playful air.

She likes to observe chaos and push others to act.

She usually presents herself with a kind smile and a relaxed air, but it's all part of the plan.



---

🌑 4. Death Devil

The fear of death.

She is the most powerful of all the horsemen, but she almost never appears directly.

Her mere presence implies the end of everything.

(She is the mother of fears. But almost no one knows her, and she doesn't want to be known either)



---

⚔️ GENERAL STRUCTURE OF THE WORLD

1. Japanese Government

It has special divisions that hunt demons. Although sometimes they also hire demons.

2. Public Devil Hunters

Like Denji, Aki, Power, Himeno… under the command of Makima.


3. Private Hunters

Freelance people, without government rules.

--

4. Demons and Hybrids

Some live mixed with humans, others in constant war.

ARE THE FOUR HORSEMEN BAD?

It depends on how you define “bad.”
They are not “classic villains” type “I want to destroy the world”, but natural forces of fear.
Each one exists because humans fear their concept: war, control, death, hunger.

👉 Thus their existence is necessary, although their actions are sometimes cruel, inhuman or twisted.
They have no human morality.
For them, killing or manipulating is as natural as breathing.

That's why they feel more like amorally powerful gods than mere demons or enemies.

--

IS MAKIMA BAD?

Makima is… complicated.

She is a manipulative, calculating being with a “divine” vision of the world.

Everything she does has a purpose — which sometimes seems noble, and other times is scary.

She sees people as tools, not as equals.

She is not bad… Not exactly. But she is dangerous. Extremely.

Not everyone.
Within the government and the hunters, most people think that Makima is just a special human with mysterious abilities.
Her true origin and power are ultra-secret, known only to a very small group (and those who know it usually… don't last long 🩸)

She herself uses her human appearance to manipulate, and since she has a position of power, no one dares to question her too much.
People obey her, fear her or idolize her. Sometimes all three at once.

---

ARE THE FOUR ALIVE?

Yes, the Four exist — they are all “active” at some point in the world.
But not all of them are together or aligned.
They do not form a united group, like “sisters of hell.”
Each one goes with their own plans, embodying their concept (War, Hunger, Death, Control).
Some even move among humans, pretending to be normal.

several use very attractive female human bodies or appearances.

---

Do the Four love each other?

not at all love or brotherhood.
Although people call them “sisters” or associate them with each other, they do not behave like family.

They have different goals, they even hate or use each other.

Between them there is a certain “natural rivalry”, because each one represents a different fear.

The closest thing to “affection” between horsemen is curiosity, resentment, or respect for power.

Sometimes they cooperate for convenience, but it is not friendship.

They hate each other sometimes.

--

Is Denji's demon important?

Too much.

The demon inside him is called Pochita, and he is actually the Chainsaw Devil, or Chainsaw Demon.

> The Chainsaw Devil is the demon that can erase the existence of other demons by devouring them.

That makes him the most feared and unique of all. If he eats another demon, that concept disappears from the world (no one will ever remember it).
For example: if he devours the Demon of Fear of the Nazis, humanity stops remembering that the Nazis existed.

That's why the Four Horsemen hate him and desire him at the same time:

They hate him because he destroys concepts (his power even threatens them).

They want him because he is the only being that can give them total control over fear. And they want to kill him.

--

💀 Are there other villains besides the Four?

Yes, many.
is full of demons and twisted humans with power, trauma or strange ideologies.

Some examples:

Gun Devil (Gun Demon): one of the most feared in the world. His appearance was so brutal that he killed millions in seconds.

Katana Man, Bomb Girl, Reze, Quanxi... hybrids with strong personalities, not necessarily villains, but enemies of Denji at some point. Who want to kill him.

In addition, there are foreign organizations that want to capture or use Denji's power for political or military purposes.

--

👁️ Do people know that the Four exist?

No, almost no one.
The Four Horsemen are a legend within the demonic world.
Ordinary humans have no idea of their existence, and the government barely has records or rumors.

Even within the world of hunters:

Only a few demons and powerful characters know that the Four exist.

No one knows their exact appearance or their real plans.

Some hunters think they are myths.

In short: the Four act from the shadows, using human identities or pawns (like Makima).
