Spoiler warning: This guide covers the complete story of the Fox Devil, including the devouring of the Leech Devil in Chapter 10, the refusal of Aki Hayakawa in the Katana Man Arc, and the abandonment of Reze in the Bomb Girl Arc.
Who Is the Fox Devil?

The Fox Devil is a devil who embodies the concept of foxes and draws power from the human fear of foxes. The Fox Devil is a minor supporting character in the Public Safety Saga of Chainsaw Man. The Fox Devil stands apart from most devils in the story because the Fox Devil maintains friendly relations with humans and holds contracts with multiple devil hunters at the same time.
The Fox Devil matters because the Fox Devil gives Aki Hayakawa the first devil power readers see used by a Public Safety hunter. The Fox Devil devours the Leech Devil in Chapter 10, and the devouring saves Denji after the fight with the Bat Devil. The Fox Devil therefore marks the point where the story shows how a professional devil hunter fights.
What Does the Fox Devil Look Like?

The Fox Devil in full form looks like an oversized arctic fox with a giant fox head covered in multiple giant eyes, each eye full of concentric circles. The arm of the Fox Devil is monstrously large, carries oversized claws, and is covered in multiple eyes. The full body of the Fox Devil is rarely shown, because contractors summon only the head or a paw in most appearances.
The colouring of the Fox Devil changes between the manga and the anime. The fur of the Fox Devil appears orange or light brown in the manga. The fur of the Fox Devil appears white in the anime. The eyes of the Fox Devil are red-orange and glow in both versions of the story.
What Is the Fox Devil’s Personality?
The Fox Devil has a friendly, superficial, and self-interested personality, built around cooperation with humans, a taste for attractive contractors, and a refusal to endure an unpleasant meal. The Fox Devil shows no conflicted feelings over killing and eating other devils. The Fox Devil eagerly asks Aki Hayakawa for permission to swallow the head of the Leech Devil.
The friendliness of the Fox Devil toward humans is genuine but conditional. The Fox Devil allows numerous devil hunters to make contracts with the Fox Devil. The Fox Devil grants only attractive people the ability to summon the head of the Fox Devil. The superficial rule shows that the Fox Devil judges contractors by appearance, not by merit or loyalty.
The self-interest of the Fox Devil appears most clearly with hybrids. The Fox Devil complains that Katana Man is monstrous, neither human nor devil, after swallowing Katana Man whole. The Fox Devil leaves immediately after tasting Reze, abandoning the Division 2 Vice Captain in the middle of a battle. The Fox Devil shows no sense of loyalty or responsibility toward contractors when a situation turns unfavourable or undesirable.
How Does a Contract With the Fox Devil Work?

A contract with the Fox Devil works through 3 elements: a price paid in body parts, a fox-head hand sign, and the cry “Kon”. The contractor forms the hand sign by shaping the fingers into a fox head, holds the sign over the eye, looks through the sign at the target, and cries “Kon”. The Fox Devil then appears, attacks the target, and vanishes in a puff of smoke. Readers who want the full system behind such bargains can read the guide on how contracts work in Chainsaw Man.
The price of the contract is food for the Fox Devil. Aki Hayakawa feeds the Fox Devil parts of the body of Aki Hayakawa, such as a layer of skin from the arm of Aki Hayakawa. Aki Hayakawa shows Denji a bandaged arm in the hospital after the fight with the Leech Devil, and the bandaged arm is the visible cost of the summoning. The Fox Devil receives the body part the Fox Devil wants in return for each summoning.
The reach of the contract has 2 limits, and both limits come from the body of the Fox Devil. The body of the Fox Devil resides in Kyoto, and the Fox Devil teleports from Kyoto to the location of a contracted hunter when summoned. The Fox Devil cannot be brought out inside a sealed space, because the sealed space blocks the body of the Fox Devil from entering. Aki Hayakawa discovers the sealed-space limit during the Eternity Devil Arc.
The head of the Fox Devil is a restricted privilege, not a standard term. The Fox Devil grants the head summoning only to contractors the Fox Devil finds attractive. Contractors outside that judgement receive a paw instead of the head, and the paw swipes at the enemy rather than devouring the enemy whole. Himeno states the attractive-only rule to Denji at the welcoming party for new Division 4 members.
What Are the Fox Devil’s Powers and Abilities?

The Fox Devil possesses 6 main powers and abilities: devouring devils whole, teleportation from Kyoto, head and paw summoning, enhanced strength, enhanced durability, and blood consumption with regeneration. The Fox Devil holds all of the standard devil abilities, including the ability to make contracts with humans for a price. The Fox Devil appears massive and powerful despite the friendly relations with humanity.
Devouring devils whole: The Fox Devil opens the giant jaw and swallows a devil in a single bite. The Fox Devil devours the Leech Devil in Chapter 10 after Aki Hayakawa grants permission. The Fox Devil swallows Katana Man whole in the Katana Man Arc and swallows Reze whole in the Bomb Girl Arc. The bite cuts through concrete and through devils with equal ease.
Head and paw summoning: A contractor summons either the head or a paw of the Fox Devil, depending on the standing of the contractor with the Fox Devil. The head devours the target whole. The paw strikes, swipes, or crushes the target. Nomo summons the arm of the Fox Devil against Reze, and Nakamura summons the front paw of the Fox Devil against the dolls of Santa Claus.
Enhanced strength and durability: The paws of the Fox Devil are strong enough to defeat multiple dolls of Santa Claus with ease. The jaw of the Fox Devil carries the strength to cut through concrete in one bite. The body of the Fox Devil survives summoning inside a building by destroying the building instead of being crushed by the building, and the Fox Devil takes no damage in the process.
Blood consumption and regeneration: The Fox Devil restores health by consuming blood, as devils do. The regenerative abilities of the Fox Devil are powerful enough to heal the head of the Fox Devil completely, even after Katana Man slashes through the head from the inside. The regeneration explains why the Fox Devil survives an escape that would destroy a lesser devil.
How Does the Fox Devil Debut in the Bat Devil Arc?
The Fox Devil debuts in Chapter 10, “Kon”, at the end of the Bat Devil Arc. The Leech Devil defeats Denji in the street and stands on the verge of eating Denji. Aki Hayakawa arrives with the Division 4 team, forms the fox-head hand sign, and summons the Fox Devil. The Fox Devil decapitates the Leech Devil with a single bite.
Why Can the Fox Devil Not Appear in the Eternity Devil Arc?
The Fox Devil cannot appear in the Eternity Devil Arc because the body of the Fox Devil sits in Kyoto, and the sealed looped space of the Eternity Devil blocks the body from entering. Aki Hayakawa tries to summon the head of the Fox Devil to break out of the looped section of space. The summoning fails, because the Fox Devil cannot be brought out inside the sealed space. The failure reveals the geographic limit of the contract.
The Eternity Devil Arc still expands the contract lore of the Fox Devil in 2 scenes. Hirokazu Arai reveals a contract with the Fox Devil at the welcoming party held by the Special Division after the defeat of the Eternity Devil. Denji asks how Aki Hayakawa and Hirokazu Arai can both hold a contract with the same devil. Aki Hayakawa explains that the Fox Devil is on good terms with humans, so multiple devil hunters hold contracts with the Fox Devil.
What Happens to the Fox Devil in the Katana Man Arc?
The Fox Devil suffers a humiliating defeat in the Katana Man Arc, in Chapter 23, “Gunfire”. Katana Man ambushes Aki Hayakawa, Himeno, Denji, and Power. Aki Hayakawa summons the head of the Fox Devil, and the head swallows Katana Man whole. The Fox Devil complains that Aki Hayakawa made the Fox Devil swallow something monstrous, neither human nor devil.
The consequences of the Katana Man Arc extend beyond the single battle. Aki Hayakawa later tries to summon the Fox Devil in the hospital, and the Fox Devil refuses to appear. Yutaro Kurose states that Aki Hayakawa used the power of the Fox Devil recklessly, got on the bad side of the Fox Devil, and probably cannot use the Fox Devil again. The Fox Devil appears by mention in Chapter 30 during the arc, and the refusal ends the contract of Aki Hayakawa in practice.
What Happens to the Fox Devil in the Bomb Girl Arc?
The Fox Devil appears in the Bomb Girl Arc in Chapter 46, “Massacre Melody”, during the assault of Reze on the Second Division headquarters. Nomo attempts to use the arm of the Fox Devil twice against Reze. Reze evades each attack of Nomo, and the evasion shows the limits of a paw summoning against a fast hybrid. Reze then moves to kill Nomo.
The Division 2 Vice Captain intervenes with the head of the Fox Devil. The Vice Captain uses the head to swallow Reze whole, repeating the devouring tactic of Aki Hayakawa. The Fox Devil immediately complains about the flavour of Reze and vanishes, leaving Reze behind. The abandonment repeats the Katana Man pattern exactly: a hybrid tastes wrong, and the Fox Devil quits the battle.
What Happens to the Fox Devil in the International Assassins Arc?
The Fox Devil appears in the International Assassins Arc in Chapter 59, “Mess”, and Chapter 60, “Quanxi and Fiends’ 49-Person Massacre”. Nakamura uses the front paw of the Fox Devil to crush multiple dolls controlled by Santa Claus. The paw summoning succeeds here because the targets are dolls, not hybrids, and the strength of the Fox Devil crushes the dolls with ease.
Does the Fox Devil Die in Chainsaw Man?
No, the Fox Devil does not die in Chainsaw Man, and no death of the Fox Devil is recorded in the story through the appearances in Chapters 10, 23, 46, 59, and 60. The Fox Devil survives the head slash of Katana Man through regeneration. The Fox Devil survives every summoning by vanishing in smoke after the attack. The Fox Devil remains alive in Kyoto, available to contractors, after the last appearance.
Fox Devil’s Relationships With Other Characters
Aki Hayakawa: Aki Hayakawa is the primary contractor of the Fox Devil and the hunter who defines the contract for readers. Aki Hayakawa summons the Fox Devil against the Leech Devil in Chapter 10 and against Katana Man in Chapter 23. The Fox Devil obeys Aki Hayakawa in the first summoning and refuses Aki Hayakawa after the second, and the refusal ends the partnership. Aki Hayakawa pays for the power with skin from the arm, and Aki Hayakawa learns that the Fox Devil punishes a reckless use.
Hirokazu Arai: Hirokazu Arai is a fellow contractor of the Fox Devil and a Division 4 newcomer. Hirokazu Arai reveals the contract at the welcoming party after the Eternity Devil Arc. The shared contract confuses Denji, and the explanation from Aki Hayakawa clarifies that the Fox Devil contracts with multiple hunters. Hirokazu Arai dies shielding Kobeni Higashiyama during the Katana Man Arc, and the death ends the use of the Fox Devil by Hirokazu Arai.
Nomo: Nomo is a Division 2 contractor of the Fox Devil and a user of the arm summoning. Nomo attempts the arm of the Fox Devil twice against Reze in Chapter 46, and Reze evades both attacks. The failure of Nomo shows the limits of a paw summoning against a hybrid. Nomo survives the encounter only because the Division 2 Vice Captain intervenes with the head summoning.
Nakamura: Nakamura is a contractor of the Fox Devil during the International Assassins Arc. Nakamura uses the front paw of the Fox Devil to crush multiple dolls controlled by Santa Claus. The success of Nakamura contrasts with the failures against hybrids, because dolls offer no bad taste and no hybrid durability. Nakamura demonstrates the practical value of a partial summoning against a crowd.
The Division 2 Vice Captain: The Division 2 Vice Captain is a contractor who holds the head privilege of the Fox Devil after Aki Hayakawa loses the privilege. The Vice Captain swallows Reze whole in Chapter 46 to save Nomo. The Fox Devil complains about the flavour of Reze and vanishes at once, leaving Reze behind. The Vice Captain therefore gains the same devouring power and the same hybrid failure as Aki Hayakawa.
Denji: Denji is the beneficiary of the debut of the Fox Devil and the student of the contract system. The Fox Devil saves Denji from the Leech Devil in Chapter 10, and Denji learns the price of the contract from Aki Hayakawa in the hospital. Denji never contracts with the Fox Devil, because Denji fights as Chainsaw Man rather than as a contracted hunter. The Fox Devil remains a symbol of professional hunting for Denji.
Leech Devil: The Leech Devil is the first victim of the Fox Devil and the proof of the devouring power. The Fox Devil decapitates the Leech Devil and swallows the head of the Leech Devil with permission from Aki Hayakawa. The Leech Devil arrives seeking revenge for the death of the Bat Devil, and the Leech Devil dies in the same arc as the Bat Devil. The devouring establishes the Fox Devil as a devil who eats devils without hesitation.
Katana Man: Katana Man is the hybrid who breaks the contract of Aki Hayakawa with the Fox Devil. The Fox Devil swallows Katana Man whole in Chapter 23, and Katana Man cuts out of the head of the Fox Devil from the inside. The Fox Devil calls Katana Man monstrous, neither human nor devil, and refuses Aki Hayakawa afterward. Katana Man therefore causes the only lasting defeat of the Fox Devil in the story.
Reze: Reze is the hybrid who repeats the Katana Man failure in the Bomb Girl Arc. The Fox Devil swallows Reze whole through the Division 2 Vice Captain, complains about the flavour of Reze, and vanishes. Reze survives the devouring unharmed and continues the assault on the Second Division headquarters. Reze proves that the taste objection of the Fox Devil applies to every hybrid, not to Katana Man alone.
Santa Claus: Santa Claus is the enemy whose dolls fall to the paw of the Fox Devil. Nakamura crushes multiple dolls of Santa Claus with the front paw of the Fox Devil in Chapters 59 and 60. The dolls offer no resistance comparable to a hybrid, and the strength of the Fox Devil crushes the dolls with ease. Santa Claus never faces the head of the Fox Devil directly, and the encounter shows the Fox Devil at full effectiveness.
