The Fox Devil contract in Roblox’s Devil Hunter leans hard into what makes Chainsaw Man fun: risky bargains for very real power. It’s a rare shrine contract that trades away an eye and some flesh in exchange for a wide-area Kon summon that can wipe groups of enemies off the map.
Devil Hunter Fox Devil contract requirements and rank
The Fox Devil is treated as a rare shrine contract in Devil Hunter. That already puts it a step above the common free-roam devils like Sea Cucumber or Leech, and it comes with steeper requirements.
You need:
- Player type: Human (only humans can sign devil contracts in Devil Hunter).
- Rank: At least Junior Hunter. If you are below this rank, the Fox Devil simply will not accept your sacrifice.
- Currency: 50,000 yen to pay the fee to Keeper Renji and open the shrine “garage”.
- Offerings: A stock of body parts, especially hearts, eyes, and arms. Legs are risky; players can be killed outright for offering them.
On top of the materials, you should go in expecting to die at least once. Once the Fox Devil starts its judgment, it can still decide you’re not worth keeping alive and end the run.
Fox Devil contract location and how to reach Keeper Renji
The Fox Devil isn’t sitting in the open world; it’s locked behind a shrine controlled by an NPC called Keeper Renji. He hides in an alley, so navigation is the first hurdle.
Step 1: Start from the main headquarters building in the city. Exit to the street level so you can move into the surrounding districts.
Step 2: Head toward the Chinatown-style area. You’re looking for a set of back alleys rather than the main street.
Step 3: Scan the alley walls for a distinctive mark. The right spot is identified by red and yellow stickers/sticky notes/curse marks all over a single wall. It’s the only wall in that area with that much decoration.
Step 4: Turn into that alley and follow the stickers around the corner. At the end of this short path, you’ll find Keeper Renji, the Fox Devil’s gatekeeper.
Once you’ve found Renji once, memorize this route from HQ to Chinatown and into the marked alley. You’ll likely come back for retries or to help friends reach the shrine.
How to unlock the Fox Devil shrine
Renji controls access to the Fox Devil’s shrine. You can’t interact with the devil at all until you pay him and step into the enclosed space.
Step 1: Talk to Keeper Renji. He introduces himself as the keeper of the Fox’s favor bargain.
Step 2: Choose the option to pay the fee. This costs 50,000 yen. Have the full amount ready; there is no partial payment.
Step 3: After paying, a gate or “garage” door opens behind Renji. Enter the shrine area and stand inside.
Step 4: Wait for the gate to fully close behind you. Do not run back out; staying inside is what triggers the teleport to the Fox Devil’s domain.
Once the gate shuts, you’re locked into the offering phase. Make sure all your offerings are already in your inventory before you walk in.
What to offer the Fox Devil (and what to avoid)
The shrine phase is all about sacrifice. You lay down body parts and flesh on the designated spots before the Fox Devil begins its judgment.
Players have had the most consistent success offering:
- Hearts: High-value offerings that the Fox Devil clearly likes.
- Eyes: Fits the series theme and are explicitly used later as part of the permanent cost.
- Arms and flesh: Additional material to show you are “giving all you can”.
Several runs point to one specific trap:
- Do not offer legs lightly. The Fox Devil can simply snap you in half if you present a leg as an offering, ending the attempt on the spot.
As you place each item, you’ll see prompts to confirm the offering. Keep going until you receive a clear message along the lines of “You’ve given all you can. No more gifts, no more chances.” That line is your signal that the Fox Devil is done taking material sacrifices and is about to move on to judgment.
Fox Devil judgment, fight, and contract signing
After the offerings are complete, the Fox Devil evaluates whether you’re worth keeping alive. This can play out in two ways, depending on the flow you get.
Judgment and combat
In many runs, the Fox Devil transitions directly into combat after the “no more gifts, no more chances” message. You’re effectively on trial:
- If you fail: The Fox Devil kills you, ending the attempt and eating your offerings and yen.
- If you succeed: A prompt appears to sign the contract.
Surviving this fight is the first gate to the contract; there’s no way to bypass it once it starts.
The permanent sacrifice: right eye and flesh
When you pass judgment and are offered the contract, the Fox Devil takes its real price. For this contract, that cost is:
- Your right eye as a permanent sacrifice.
- Flesh, represented by the accumulated offerings and the specific sacrifice text when you sign.
The right-eye sacrifice is not just cosmetic. In Devil Hunter, losing an eye has gameplay impact: it can lower your accuracy and subtly affect how you track enemies in combat. Your character model also reflects the loss, which is why players with Fox contracts often appear with one eye closed.
Once you confirm the contract, the Fox Devil marks you and grants access to its abilities. From that point on, breaking the contract – such as by violating its terms through the game’s contract systems – means death and a full reset, unless you later use a rare devil eraser to undo it.
How the Fox Devil contract works (Kon ability)
The Fox Devil contract models Aki Hayakawa’s bargain from Chainsaw Man fairly closely. In the series, Aki feeds the Fox Devil parts of his body to borrow its power and summon its head with a hand sign and the word “Kon”.
In Devil Hunter, once the contract is active, you gain access to a Kon-style summon mapped to your devil contract slots:
- Summon behavior: Calling Kon brings out the Fox Devil to bite a target enemy and the surrounding area, then vanish in a puff of smoke.
- Range and coverage: The attack has a large hitbox and wide area, making it well suited for clearing groups of enemies or controlling a crowded fight.
- Targeting: It’s especially effective against devils and standard enemies. In the Chainsaw Man fiction, the Fox Devil struggles with hybrids and dislikes their taste, and the in-game move leans more toward shredding typical targets rather than bosses with hybrid-style durability.
Fox also plugs into the broader contract system. You build devil favor by killing enemies and players while using its abilities. As favor rises, you unlock additional variants and improvements on your contract skills, including how your mouse button 2 (M2) variants interact with humanoid enemies.
Best weapons and playstyles for Fox Devil
The Fox Devil’s Kon summon is all about spacing and catching multiple targets at once. It pairs well with weapon sets that let you stay mobile while setting up the bite.
Players get good results with:
- Medium-class weapons like the katana: These sit in a sweet spot between speed and reach. You can dash in, stagger enemies, then drop a Kon summon that bites through the clustered group.
- Aggressive, offensive builds: If you like to stay on the front foot and delete groups quickly rather than playing defensively, Fox fits that mindset.
If your style leans more toward survival, counters, and invincibility frames, something like the Future Devil contract is better aligned. Fox is less about escaping danger and more about erasing it in a single, dramatic attack.
Where Fox Devil sits among other contracts
Fox is not the only powerful option in Devil Hunter, but it occupies a particular niche among shrine contracts and rares.
| Devil | Rarity | Location type | Main sacrifice | Core ability |
|---|---|---|---|---|
| Fox | Rare | Shrine | Right eye and flesh | Kon summon, wide-area bite |
| Snake | Rare | Shrine | 20 hearts | Swallow, store, and spit enemies |
| Leech | Common | Free roam | Heart | Life leech, passive healing |
| Future | Special | Floor Zero | 30 eyes | Future Sight counter with i-frames |
| Cursed | Legendary | Floor Zero | Lifespan | Cursed sword execute |
Fox becomes an especially strong pick if you:
- Want a high-impact, low-setup AoE that doesn’t require complex positioning.
- Are comfortable trading a permanent body part (your right eye) for raw offensive power.
- Already run a build that thrives on moving quickly into mid-range fights rather than sniping from afar.
It’s less ideal if you rely heavily on precise ranged aiming, since losing an eye can make your accuracy feel worse, and the Kon summon is not a precision tool compared with something like the Cursed Devil’s execute.
Once you’ve signed the Fox Devil contract and learned how to work with Kon’s huge bite radius, it’s one of the most satisfying ways to clear a street full of devils in Devil Hunter. The price is steep – an eye, some flesh, and a non-trivial risk of death on each attempt – but that’s exactly the kind of bargain Chainsaw Man is built on.
