What Is the Fox Devil?
The Fox Devil is one of the most well-known devils in Chainsaw Man, frequently summoned by Public Safety Devil Hunters — including Aki Hayakawa.

It takes the form of a massive fox, estimated to be over 10 meters tall, with multiple eyes on its head.
Despite being relatively friendly toward humans, the Fox Devil has a mischievous and whimsical personality — fitting for a creature inspired by Japanese folklore.
The Fox Devil prefers to make contracts with handsome male Devil Hunters, as she is described as a female devil who loves good-looking men.Even if friendly, it’s notoriously fickle — refusing to answer a summon or abandoning a fight if displeased.
Some fans criticize it for its limited appearances and question whether it’s weak or unreliable.
In this article, we’ll explore the Fox Devil’s abilities, contracts, personality, and all known contractors in Chainsaw Man.
The Fox Devil’s True Body Is in Kyoto
While the Fox Devil can appear anywhere when summoned, its true body is said to reside in Kyoto, under the supervision of Public Safety.
Like the Future Devil, it’s believed to be under government control, and only official Devil Hunters are allowed to form contracts with it.
Contract Terms and the Devil’s Price
The Fox Devil’s contract requires a physical offering from its user — usually a part of their body.
In Chapter 11, after defeating the Leech Devil, Aki Hayakawa explains to Denji that the price he paid was a piece of his skin.

Sometimes, the Fox Devil demands hair instead.
This explains Aki’s distinctive topknot hairstyle — and even the long hair of the handsome Division 2 Vice Captain, who can summon the Fox Devil’s head.
This suggests the Fox Devil often takes hair as its preferred offering from attractive hunters.
The Fox Devil’s Powers
The Fox Devil can summon parts of its body — most often its head or hand — to devour enemies instantly.
In its debut scene, it overwhelmed the Leech Devil in seconds with a single bite.
However, only good-looking male hunters can summon the head.
Aki and the handsome Vice Captain can do this, while less attractive hunters like Nomo or Nakamura can only summon the leg or hand.

This has become a humorous detail among fans — proof that, in Chainsaw Man, even devils care about looks.
The Fox Devil’s Limitations
While powerful against lower-level devils, the Fox Devil refuses to fight enemies stronger than itself, such as Weapon Hybrids.
This capricious nature has led some fans to label it “weak” or “unreliable,” though it’s more accurate to say it simply knows its limits.
The Fox in Japanese Mythology

In Japanese folklore, foxes (kitsune) are mischievous tricksters who sometimes help humans but also enjoy deceiving them.
They’re also seen as messengers of the gods, especially at Inari shrines.
This cultural background might explain why the Fox Devil in Chainsaw Man is both friendly and unpredictable — a being that mirrors Japan’s complex view of fox spirits.

Aki was the first major user of the Fox Devil’s power.
He used it in the battles against the Leech Devil (Chapter 11) and the Katana Man (Chapter 23).
However, after forcing it to eat the Katana Man — whom it found disgusting — the Fox Devil refused to cooperate with Aki again, effectively ending their contract.
“You made me eat something revolting,” the Fox Devil says, before cutting off ties with him.
Hirokazu Arai

A new Devil Hunter from Public Safety Division 4 who also had a contract with the Fox Devil.
However, he was killed before ever showing the ability in action.
Since he’s not particularly handsome, fans joke that the Fox Devil might not have liked him much.
Nomo (Division 2)

A skilled Devil Hunter who could only summon the Fox’s leg, implying he wasn’t considered handsome enough for the head.
Despite this, he was strong and brave, surviving explosions from Reze before being killed in battle — a quiet hero in the Reze Arc.

A handsome hunter who could summon the Fox’s head, using it to attack Reze.
Unfortunately, he and Nomo were both killed during the battle, with their heads cut off by Reze.
Nakamura
Another Division 2 Hunter who could summon only the Fox’s hand.
He’s best remembered for shouting “KON!” — the summon word for the Fox Devil — before being swiftly killed by Quanxi.
Summary: The Fox Devil’s Nature and Possible Return
- The Fox Devil’s contracts require a physical sacrifice (skin or hair).
- Only handsome male hunters can summon the head; others can use the hand or leg.
- It’s strong against lesser devils but refuses to fight superior ones like Reze or Weapon Hybrids.
- Despite being moody, it remains one of the most iconic devils in Chainsaw Man.
Since the Fox Devil hasn’t been confirmed dead, a return in Chainsaw Man Part 2 is still very possible — perhaps with a new contractor or in a reimagined form.
