Every Chainsaw Man Devil Contract Explained: Powers, Prices, and Hidden Risks

Devil Contracts are the foundation of Chainsaw Man’s power system, but they are not ordinary supernatural abilities. A human receives power, protection, information, or assistance from a devil, while the devil receives a price it considers valuable. That price can be a body part, years of life, a human sacrifice, or a condition whose real danger is not obvious until much later.

The most important contracts include Denji’s agreement with Pochita, Aki Hayakawa’s contracts with the Fox, Curse, and Future Devils, Himeno’s bargain with the Ghost Devil, Akane Sawatari’s Snake Devil contract, and Makima’s agreement with Japan’s prime minister. Later manga arcs expand the system through the Hell, Darkness, Gun, Doll, and Fire Devils.

This guide covers the named and clearly established Devil Contracts in the story, along with important contract offers that affect the plot. It does not treat every alliance between a human and a devil as a contract, because hybrids, fiends, possession, coercion, and simple cooperation do not always follow the same rules.

Spoiler Warning: The first half discusses material covered by the anime’s Public Safety arc. Later sections contain major manga spoilers for Chainsaw Man Parts 1 and 2.

Macht of the Golden Land Explained: Frieren Season 3’s Most Important Villain

August 16, 2026

The table simplifies several bargains whose wording, enforcement, or exact payment remains intentionally unclear. In Chainsaw Man, uncertainty is often part of the danger.

How Do Devil Contracts Work in Chainsaw Man?

A Devil Contract is a binding agreement between a human and a devil. Both sides state what they will give, and the agreement becomes enforceable once accepted. The series treats a valid contract as something neither party can casually ignore.

Three rules matter most:

1. The price does not need to be equal by human standards. A devil may value a contractor’s eye, lifespan, pain, curiosity, or future differently.
2. Different people can receive different prices. The Fox Devil is willing to work with many Devil Hunters, but its fee and level of cooperation vary.
3. The wording matters. A contract may grant exactly what was promised while still exposing the human to consequences the agreement never prevented.

This is why contracts are more frightening than a simple magic system. They reward desperation. A contractor often accepts the price when survival feels more urgent than the future.

Denji and Pochita’s Chainsaw Devil Contract

Denji’s contract with Pochita is the most important agreement in the series. After Denji is killed and dismembered, Pochita becomes his heart and restores him as Chainsaw Man. In return, Pochita asks Denji to show him his dreams.

The wording is unusually compassionate. Pochita does not demand Denji’s lifespan or another victim. He wants Denji to live the ordinary life that poverty, debt, and abuse denied him.

Power granted

Denji can transform by pulling the starter cord in his chest. Chainsaws emerge from his head and arms, and blood allows him to heal from extreme injuries. As a hybrid, he can return from forms of damage that would kill an ordinary human.

Price

Denji must continue pursuing and showing Pochita his dreams. The agreement depends on Denji retaining the ability to imagine a better life.

Hidden risk

The hidden vulnerability is psychological rather than physical. If Denji’s dreams are systematically destroyed and he can no longer live according to the contract’s purpose, the balance between Denji and Pochita can collapse. Makima recognizes that attacking Denji’s sense of hope is more effective than merely injuring his body.

The contract therefore makes Denji extraordinarily difficult to kill but leaves him vulnerable to emotional manipulation. It is one of Fujimoto’s clearest examples of a bargain whose price is inseparable from a character’s reason to live.

Aki Hayakawa’s Fox Devil Contract

Aki’s first major contract is with the Fox Devil. By forming a hand sign and saying “Kon,” he can summon the Fox Devil’s head to bite and swallow a target. Other contracted hunters can summon different parts of its body.

Power granted

The Fox Devil provides a fast, large-scale attack that is especially useful against ordinary devils. Its sudden appearance allows hunters to destroy or immobilize a target before a prolonged battle begins.

Price

The Fox Devil consumes parts of the contractor’s body. The exact payment differs between users and summons. Aki is considered attractive by the Fox Devil, which helps explain why it permits him to summon its head.

Hidden risk

The Fox Devil has preferences and can refuse cooperation. After being forced to bite Katana Man, it becomes angry with Aki and stops answering him. The contract grants access to a sentient being, not a guaranteed weapon.

That distinction is crucial. A Devil Hunter who depends too heavily on one contracted devil can lose an essential ability at the moment it becomes offended, frightened, or dissatisfied.

Aki Hayakawa’s Curse Devil Contract

The Curse Devil gives Aki one of his deadliest attacks. Aki uses a sword shaped like a large nail. After he pierces the same target three times, the Curse Devil appears and crushes the victim.

Power granted

The curse can inflict a seemingly unavoidable execution once its conditions are met. It allows a human hunter to threaten opponents who are much stronger than a normal person.

Price

Every use consumes a substantial portion of Aki’s lifespan. After using it against Katana Man, Aki learns that he has only two years left to live.

Hidden risk

The technique’s apparent certainty can be misleading. Katana Man survives because of his hybrid nature. Aki pays a permanent cost for an attack that does not produce a permanent result.

Aki Hayakawa’s Future Devil Contract

After losing access to the Fox Devil and learning the cost of the Curse Devil, Aki forms a contract with the Future Devil.

Power granted

The Future Devil lives in Aki’s right eye and lets him see a short distance into the future. This does not make Aki invincible, but it improves his reactions and allows him to anticipate attacks.

Price

Unlike the severe payments demanded from previous contractors, the Future Devil asks to live inside Aki’s eye. It accepts this unusually light price because it has seen Aki’s future and wants to witness his death directly.

Hidden risk

Precognition does not guarantee the power to change what is seen. Aki can understand an approaching attack and still lack the speed, position, or strength to avoid it.

Himeno’s Ghost Devil Contract

Himeno gives her right eye to the Ghost Devil in exchange for permanent use of one of its arms. The invisible arm can grab, restrain, choke, or pull objects without exposing Himeno directly.

Power granted

The Ghost Devil’s arm gives Himeno flexible close-range control. Because most opponents cannot see it, the arm can attack from unexpected angles.

Initial price

Himeno sacrifices her right eye.

Final price

During the ambush by Katana Man and Akane Sawatari, Himeno offers the Ghost Devil all of herself in exchange for its full power. Her body disappears piece by piece until nothing remains.

Hidden risk

A contract can apparently be expanded through a new offer. Himeno’s original bargain costs only an eye, but desperation leads her to renegotiate with her entire existence as payment.

Akane Sawatari’s Snake Devil Contract

Akane Sawatari can summon the Snake Devil by giving up fingernails. The Snake Devil can swallow targets and later release devils it has consumed.

Power granted

The Snake Devil is fast enough to devour the Ghost Devil and can reproduce at least part of a swallowed devil’s power.

Price

Each command costs Akane fingernails.

Hidden risk

A cheap-looking renewable payment can encourage repeated use. Fingernails grow back, but the contract still requires self-mutilation and places Akane in a relationship with a powerful devil whose broader terms are not fully explained.

The Yakuza Boss and the Zombie Devil

The yakuza boss responsible for Denji’s debt makes a deal with the Zombie Devil. He and his followers receive power but are transformed into zombies under the devil’s control.

Hidden risk

The contractor may technically receive power while becoming incapable of enjoying it. The yakuza believe they are acquiring an advantage, but the Zombie Devil turns them into property.

The Eternity Devil’s Contract Offer

When Division 4 becomes trapped on the eighth floor of a hotel, the Eternity Devil offers a contract: kill Denji and feed his heart to the devil, and everyone else will be allowed to leave safely.

The contract weaponizes group fear. The Eternity Devil does not need to defeat Denji personally if panic persuades his allies to sacrifice him.

Kishibe’s Contracts With the Claw, Knife, and Needle Devils

Kishibe is stated to have contracts with the Claw, Knife, and Needle Devils. However, the manga does not fully reveal their abilities, activation conditions, or prices.

The lack of information is meaningful. Public Safety hunters often operate with abilities that colleagues and enemies cannot completely assess.

The Punishment Devil Contracts

Kyoto agents Michiko Tendo and Yutaro Kurose are associated with the Punishment Devil. Its exact independent ability and price are not clearly explained.

Hirokazu Kusakabe’s Stone Devil Contract

Public Safety hunter Hirokazu Kusakabe contracts with the Stone Devil. By breathing into a circular pattern made with his hand, he can petrify a target caught within the effect. The manga does not clearly state the cost.

The Hell Devil Contracts

The Hell Devil can transport beings between Earth and Hell. Santa Claus offers children as payment to send Denji and the other Devil Hunters to Hell, while a Public Safety squad later offers their lives to summon it against Makima.

The hidden risk is that the Hell Devil changes location, not the balance of power. Sending an enemy to Hell may expose everyone involved to something far worse.

Santa Claus and the Doll Devil

Santa Claus possesses the Doll Devil’s power, allowing humans to be converted into dolls through touch. Those dolls can spread the transformation to others. The original price is not explicitly revealed.

Santa Claus’s Contract With the Darkness Devil

Santa Claus offers the Darkness Devil Chainsaw Man’s heart in exchange for power capable of killing Makima. The Darkness Devil gives Santa a piece of its flesh, dramatically strengthening the Doll Devil network.

The bargain provides enormous power but still fails strategically. Greater strength cannot compensate for flawed assumptions about Denji, Makima, and the Doll network’s weaknesses.

Makima’s Contract With Japan’s Prime Minister

Makima’s contract with Japan’s prime minister converts attacks made against her into illnesses or accidents affecting Japanese citizens.

Hidden risk

The contract transforms an entire nation into Makima’s reserve of replacement lives. It also changes the meaning of attacking her: violence against Makima becomes violence against innocent people.

Denji ultimately exploits the agreement’s wording by treating his act as love rather than an attack. The solution depends on interpreting the contract, not overpowering it.

The United States President’s Gun Devil Contract

The president of the United States sacrifices one year from every American citizen’s lifespan to deploy the Gun Devil against Makima.

The people paying the price never consent, and the scale of the sacrifice still does not guarantee victory.

The Blood Devil’s Contract With Denji

Power gives Denji her blood and asks him to find the reincarnated Blood Devil and turn it back into Power.

The agreement mirrors Pochita’s contract. Its price is not mutilation but responsibility: Denji must continue living and form a new bond rather than merely mourn the old one.

Part 2: Asa Mitaka and Yoru Are Not a Normal Devil Contract

Major Manga Spoilers: The following sections discuss Chainsaw Man Part 2.

Yoru saves Asa Mitaka after a fatal attack by occupying part of her brain. This resembles a contract but is not presented with the same clear offer-and-acceptance structure used by Devil Hunters. It is better understood as forced coexistence or partial possession unless the manga defines it otherwise.

The Fire Devil Contracts and the Chainsaw Man Church

The Chainsaw Man Church’s followers believe they are contracting with the Justice Devil, but later revelations identify the Fire Devil as the source of their transformations.

The Fire Devil transforms contractors according to their desires. The practical price is loss of control, identity, and human form.

The hidden danger is deception: the contractors do not understand the identity of the devil with which they are dealing.

What Makes a Devil Contract Truly Dangerous?

The obvious danger is the price, but the series repeatedly shows five deeper risks.

1. The ability may not guarantee the desired outcome

Himeno sacrifices everything, yet the Ghost Devil loses. Aki spends his lifespan, yet Katana Man revives.

2. The devil remains an independent personality

The Fox Devil can become offended. The Future Devil enjoys Aki’s fate. A contracted devil is not neutral equipment.

3. The contract may exploit wording

Makima’s protection depends on what qualifies as an attack. Pochita’s agreement depends on Denji’s dreams.

4. Someone else may pay

Political contracts make civilians bear costs without consent. Santa Claus sacrifices children and disposable bodies.

5. Desire can be the trap

The Fire Devil gives followers forms shaped by what they want. Contracts expose what a character is desperate enough to trade away.

Why Devil Contracts Matter to Chainsaw Man’s Story

Devil Contracts turn power into a moral and psychological decision. A character’s ability tells us what they fear, but the price tells us what they are willing to lose.

Aki trades away his future because revenge has made the future feel less valuable. Himeno gives her entire body because saving Aki matters more to her than survival. National leaders spend citizens’ lives as political resources. Denji’s most important contracts, by contrast, ask him to keep living and maintain relationships.

The hidden rule of Chainsaw Man is not merely that power has a cost. It is that the nature of the cost reveals the relationship behind the power.

Frequently Asked Questions

Can devils break contracts in Chainsaw Man?

Valid contracts are treated as binding, and breaking one carries fatal consequences. A devil may still refuse a request that falls outside the agreed terms, and unclear wording can create limitations or loopholes.

Why did the Future Devil charge Aki so little?

The Future Devil had already seen Aki’s death and wanted to witness it directly.

What is the most expensive Devil Contract?

By individual cost, Himeno’s final Ghost Devil bargain requires her entire body and life. By collective scale, the Gun Devil and Control Devil contracts affect national populations.

Is Denji’s bond with Pochita really a contract?

Yes. Pochita gives Denji his heart in exchange for seeing Denji pursue his dreams.

Does Asa have a contract with the War Devil?

The manga has not framed Asa and Yoru’s shared body as a conventional contract with clearly accepted terms.

Final Takeaway

The strongest Chainsaw Man Devil Contracts are not always the ones with the largest attacks. They are the bargains whose wording reshapes a person’s life.

Aki’s contracts turn revenge into lost time. Himeno’s contract turns love into self-erasure. Makima’s contract turns citizens into protection. Pochita and Power use contracts to give Denji a reason to continue.

That is the hidden risk behind every deal: the contractor is not only purchasing power. They are deciding what part of themselves—or someone else—they believe can be spent.
