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

From the first yakuza mess to the Tokyo ambush, the anime version of ‘Chainsaw Man’ shows how humans bargain with terrifying entities to borrow power, pay steep prices, and skirt death—at least for a while. Below, you’ll find every major contract or explicit devil deal the anime depicts or names, with who made it, what the ability does, the cost or conditions, and how it plays out on screen. No manga-only reveals here—just what the episodes establish, demonstrate, or directly state.

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

Denji survives after Pochita becomes his heart, formed through a simple, spoken promise. The deal’s condition is that Denji shows Pochita the ordinary dreams he never got to have. This contract explains Denji’s hybrid transformation and why he can pull a cord from his chest to become the chainsaw-armed hunter. The anime frames it as a life-saving pact that binds their futures, with Pochita’s power enabling Denji’s regeneration and transformation in battle.

Aki Hayakawa – ‘Fox Devil’ Contract

Aki can summon parts of the ‘Fox Devil’—most often the head—by forming a hand sign and calling “Kon.” In exchange, he routinely provides the fox portions of his flesh, a common feeding clause Public Safety hunters accept. The anime shows the fox swallowing devils or hybrids at Aki’s command, illustrating fast, mid-range offense. It also establishes a limitation: the fox refuses further help if it’s made to ingest something it “dislikes,” restricting future use.

Aki Hayakawa – ‘Curse Devil’ Contract

Aki wields a nail-shaped weapon that, when stabbed and counted down, triggers the ‘Curse Devil’ to execute the target. The power delivers a devastating finishing blow, but it shortens Aki’s lifespan as the principal cost. The anime demonstrates both the ritualized activation—stab and count—and the toll the curse exacts. It’s a high-risk option Aki reserves for moments when standard tactics won’t work.

Aki Hayakawa – ‘Future Devil’ Contract

After entering the ‘Future Devil’s’ containment room, Aki agrees to let the devil live in his right eye. In return, he gains the ability to see slightly into the future, improving his timing and survivability in close-quarters fights. The anime emphasizes how the eye-based residence is the payment rather than losing limbs or years of life. Practically, it turns Aki’s swordplay and dodges into pre-emptive counters guided by brief foresight.

Himeno – ‘Ghost Devil’ Contract

Himeno trades parts of her body—most visibly her right eye—for the ‘Ghost Devil’s’ invisible arms. The arms can grasp, choke, and fight while remaining unseen, giving her a stealthy reach advantage. The anime shows that the ghost’s senses differ from humans, making fear and calmness tactically relevant in confrontations. Himeno’s missing eye is the lasting sign of her payment, reflecting an ongoing cost for consistent access.

Himeno – Final Trade with the ‘Ghost Devil’

In the ambush against their division, Himeno offers the ‘Ghost Devil’ everything she has left to protect Aki. The contract escalates from a part-for-power exchange to a total sacrifice, letting the ghost fully manifest and fight at maximum strength. The anime depicts the consequences immediately: the more the ghost fights for her, the more Himeno’s body vanishes. It’s the clearest on-screen example of a contract scaling its cost with the requested power.

Kobeni Higashiyama – Contract with an Unknown Devil

The anime states Kobeni has a contract, but it withholds which devil and what she paid. Even so, her burst-speed, evasiveness, and knife work imply a practical edge that’s more than training alone. Because the show never names the partner or terms, viewers only see the outcomes—a sudden leap in agility and survival instincts. This preserves the mystery while confirming she’s empowered by a bona fide pact.

Akane Sawatari – ‘Snake Devil’ Contract

Akane commands the ‘Snake Devil’ with concise orders, such as “Swallow it whole” or “Spit it out,” to remove or redeploy targets. The anime shows the snake erasing summoned entities in an instant, and later regurgitating them on command. The cost isn’t spelled out on screen, but the direct, voice-based control indicates a standing agreement rather than a one-off bargain. This contract enables battlefield cleanup, assassination, and retrieval with minimal exposure.

Katana Man’s Crew – ‘Gun Devil’ Contracts

During the coordinated attacks in Tokyo, multiple assailants are described as having contracts with the ‘Gun Devil.’ The anime ties these deals to the unprecedented spread of firearms among criminals, elevating their threat level. Specific payments are not detailed, but the arrangement grants access to guns and backing power beyond normal humans. This network of contracts sets up the ambush’s lethality against Public Safety.

The Yakuza – ‘Zombie Devil’ Contract

In the opening episode, a yakuza group trades loyalty—and ultimately their humanity—for the ‘Zombie Devil’s’ power. The anime shows the cost as a total transformation into mindless zombies serving the devil’s will. The contract amplifies their numbers and brute force while stripping agency, turning the gang into expendable shock troops. It also establishes early that deals can backfire catastrophically on the human side.

Eternity Devil – The Hotel Deal

Trapped on a looping floor, the Eternity Devil offers freedom to the hunters if they kill Denji. Several characters consider or accept the condition, making it a temporary, situation-specific contract proposal. The anime makes the terms explicit: a single death in exchange for ending the time lock. Denji’s choice to fight instead collapses the deal by attacking the contractor directly, breaking the stalemate through attrition.

Makima – Unnamed Ritual Contract (Temple Sacrifice)

At a mountain temple, Makima conducts a ritual using death-row convicts to eliminate distant enemies. The anime does not name the devil involved, but it shows a clear exchange: each convict’s life fuels the remote execution of a named target. The one-to-one sacrificial ratio functions like a priced ledger for long-range kills. This sequence confirms that some contracts require elaborate setups and third-party offerings rather than the contractor’s own body.

Public Safety – Standard ‘Fox Devil’ Feeding Clause

Beyond Aki, the anime indicates that the ‘Fox Devil’ keeps multiple arrangements with urban hunters, accepting flesh in return for partial summons. Summoning often requires a regional bond and a verbal cue, with the devil’s cooperation varying by its preferences. The show demonstrates that misuse—like feeding it something it rejects—can terminate the agreement. This establishes the fox as a widely leveraged, but temperamental, resource across divisions.

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

When Aki meets the ‘Future Devil,’ the anime mentions previous human contractors and what they gave up. Examples include severe bodily sacrifices, underscoring that the devil typically demands steep, personal costs. By contrast, living inside Aki’s eye is portrayed as an unusual, tailored price. These details frame the future-sight boon as powerful but historically expensive, with Aki’s terms standing out among known cases.

Hirokazu Arai – ‘Fox Devil’ Contract

Arai is presented as a rookie with a standing arrangement to borrow the ‘Fox Devil’s’ power under the same flesh-for-summon terms used by other hunters. The anime shows him relying on the fox for rapid neutralization, mirroring the standard hand sign and call activation. His access demonstrates how Public Safety distributes contracts across newer agents for basic offense and containment. The narrative then underlines the risks, as rookies with such deals remain vulnerable during coordinated enemy strikes.
