15 Best Devil Contracts in ‘Chansaw Man’ Explained (Anime-Only Context)

by

The ‘Chainsaw Man’ anime explores the dangerous world of devil contracts, where humans trade with powerful, frightening beings for abilities. These deals always come with a significant cost, and only delay the inevitable—death. Here’s a breakdown of every major contract shown in the anime, including who made it, what power it grants, the price they pay, and how it unfolds in the series. This focuses solely on information presented in the anime episodes, without including details exclusive to the manga.

Denji – Contract with the ‘Chainsaw Devil’ (Pochita)

Denji was saved from death when Pochita merged with him, becoming his heart after a simple promise. He vowed to show Pochita all the normal, everyday experiences Pochita missed out on. This agreement is the reason Denji can transform into a hybrid being and summon a cord from his chest to become the chainsaw-powered hunter. The anime portrays this as a life-or-death agreement, linking their fates together – Pochita’s power allows Denji to heal and change forms during fights.

Aki Hayakawa – ‘Fox Devil’ Contract

As a fan, I’m fascinated by Aki’s ability! He can summon parts of the Fox Devil – usually just the head – by doing a hand sign and saying “Kon.” The cool thing is, Public Safety hunters seem to understand he has to give the fox pieces of his own flesh as payment. We see in the anime that Aki can command the fox to just swallow other devils or hybrids, which makes for some seriously quick attacks at a medium range. But there’s a catch: the fox has standards! If Aki tries to make it eat something it doesn’t like, it just refuses to help anymore, which limits how often he can use it. It’s a really interesting power with a built-in weakness!

Aki Hayakawa – ‘Curse Devil’ Contract

Aki fights with a weapon shaped like a nail. When he stabs an enemy with it and counts down, a powerful curse is unleashed, instantly defeating the target. However, using this ability significantly shortens Aki’s life. The anime shows both how the power is activated—through stabbing and counting—and the heavy price Aki pays for using it. He only uses this dangerous ability when other methods have failed.

Aki Hayakawa – ‘Future Devil’ Contract

When Aki enters the ‘Future Devil’s’ containment room, he makes a deal: the devil will live inside his right eye. This gives Aki a limited ability to see into the future, making him faster and more likely to survive in fights. The anime highlights that the devil’s home is Aki’s eye, rather than taking his life or body parts. Essentially, this allows Aki to anticipate his opponents’ moves, turning his sword fighting and evasions into perfectly timed reactions based on brief glimpses of what’s about to happen.

Himeno – ‘Ghost Devil’ Contract

Himeno makes a deal with a Ghost Devil, sacrificing parts of her body – most noticeably her right eye – to gain invisible arms. These arms allow her to attack and grapple opponents stealthily, giving her a hidden reach. The anime reveals that the Ghost Devil perceives the world differently than humans, meaning an opponent’s fear or composure can affect battles. Himeno’s lost eye serves as a constant reminder of the price she continues to pay for using the Devil’s power.

Himeno – Final Trade with the ‘Ghost Devil’

During an ambush on their unit, Himeno gives everything she has to the ‘Ghost Devil’ to save Aki. Their deal starts with a simple exchange – a body part for power – but quickly becomes a complete sacrifice, allowing the ghost to fully appear and fight with all its strength. The anime shows the immediate results: as the ghost fights harder for her, Himeno’s body starts to disappear. This is the most direct visual representation of a contract where the price increases with the amount of power requested.

Kobeni Higashiyama – Contract with an Unknown Devil

The anime reveals Kobeni made a deal with a devil, but keeps the details—who it was and what she offered in return—secret. Her incredible speed, dodging skills, and knife fighting suggest she has abilities beyond what normal training could provide. Since the show doesn’t explain the specifics of the deal, we only see the results: a sudden boost in her reflexes and ability to survive. This keeps an element of mystery while confirming she gained her powers through a real, magical agreement.

Akane Sawatari – ‘Snake Devil’ Contract

Akane controls a powerful entity called ‘Snake Devil’ using simple spoken commands like “Swallow” and “Spit out” to eliminate or reposition opponents. The anime depicts the snake instantly destroying summoned creatures and then bringing them back when told. While the exact terms aren’t shown, Akane’s direct control suggests a long-term agreement, not a simple deal. This arrangement allows her to quickly clear the battlefield, carry out assassinations, and recover objects with very little risk to herself.

Katana Man’s Crew – ‘Gun Devil’ Contracts

The attacks in Tokyo involved several attackers who had made deals with the ‘Gun Devil.’ The anime suggests these deals are the reason for the sudden increase in guns available to criminals, making them much more dangerous. While the specifics of these deals aren’t explained, they provide access to weapons and a powerful support system that goes beyond normal human capabilities. This network of agreements is what made the ambush so deadly for Public Safety.

The Yakuza – ‘Zombie Devil’ Contract

The first episode reveals a yakuza gang sacrificing their honor and, eventually, their very selves to gain power from the ‘Zombie Devil.’ This power completely transforms them into unthinking zombies, forced to obey the devil’s commands. While the deal increases their numbers and strength, it robs them of free will, reducing the gang to disposable soldiers. The episode also clearly demonstrates that making deals with such beings can have devastating consequences for humans.

Eternity Devil – The Hotel Deal

The hunters find themselves stuck in a time loop created by the Eternity Devil, who promises to release them if they eliminate Denji. Several characters contemplate or agree to this deal, essentially a temporary contract: Denji’s life for their freedom. The anime clearly states the terms: one death ends the loop. However, Denji chooses to fight, which breaks the agreement by directly attacking the Devil, ultimately resolving the deadlock through force.

Makima – Unnamed Ritual Contract (Temple Sacrifice)

In a secluded mountain temple, Makima performs a ritual where the lives of death-row inmates are used to eliminate enemies from afar. While the specific devil powering this ability isn’t identified, the anime clearly demonstrates a direct trade: each inmate’s life is exchanged for the death of a designated target. This system works like a costly record of long-distance assassinations, proving that some contracts necessitate complex preparations and the sacrifice of others, not just the person making the deal.

Public Safety – Standard ‘Fox Devil’ Feeding Clause

The anime reveals that the Fox Devil isn’t just connected to Aki; it has deals with many hunters in the city. These hunters offer the devil flesh in exchange for limited summoning rights. Summoning requires a connection to the local area and a specific phrase, and how well the summoning works depends on the devil’s mood. The show makes it clear that if hunters try to feed it something it doesn’t like, the deal will be broken. This shows the fox is a valuable but unpredictable resource used by different hunter groups.

Future Devil – Prior Contractors’ Terms (As Stated On Screen)

The anime reveals that previous people who made deals with the ‘Future Devil’ had to pay a high price, often involving significant physical sacrifices. This highlights that the devil usually demands something deeply personal in return. However, the deal Aki makes – living inside his eye – is presented as a unique and unusual cost. This sets up the ability to see the future as a powerful gift, but one that has historically come at a great expense, making Aki’s situation different from others.

Hirokazu Arai – ‘Fox Devil’ Contract

Arai is a new hunter who can borrow power from the ‘Fox Devil’ in exchange for offering his own flesh – a common arrangement for hunters. The anime depicts him using this power quickly, activating it with a specific hand sign, just like other users. This shows how Public Safety gives these contracts to newer agents to help with basic attacks and controlling threats. However, the story also highlights the danger: rookies who make these deals are easily targeted when enemies attack together.
