Abilities: Contracted with the Fox, Curse, and Future Devils. He can see a few seconds into the future or kill enemies instantly with a curse by stabbing them with his sword. Control: He forcibly squeezes out power by offering his 'lifespan' and 'body parts' as payment. He tries to stay rational, but every time he becomes emotional to save a comrade, he risks his lifespan being drastically shortened.

Personality (Deeply caring but prickly): On the outside, he seems like a cold, stoic stickler for rules, but inside, he is the most human and kind adult who sheds tears over the deaths of his comrades and looks after the protagonists. Abilities & Control: He uses power through contracts with the Fox, Curse, and Future Devils. Since he must pay with his body and 'lifespan,' he tries to control his power consumption rationally without getting caught up in emotions.

When Aki forms the shape of a fox head with his right fingers and says "Kon," the head of the Fox Devil is summoned to swallow the enemy. It comes from 'Kon Kon,' the Japanese onomatopoeia for a fox's cry.

Abilities: Perfectly dominates and controls the minds and abilities of beings (humans, devils, animals) she deems inferior to herself.

While she thoroughly controls others as tools, her control has limits as it does not work on the one she truly admires (Chainsaw Man).

Personality (Business-like Coldness): Usually appears to be a kind and inclusive perfect leader, but inside, she is an extreme cold-blood who sees others only as dogs or tools. Abilities & Control: Uses the 'Control' ability to perfectly manipulate those she judges to be of a lower rank. She restrains and controls her power perfectly with her own thorough logic.

Abilities: Swims freely through concrete floors or building walls as if they were water to perform ambushes or move around. Control: As a fiend with a few screws loose, he is usually uncontrollable, but he is perfectly controlled and shows absolute obedience to a single word from 'Denji,' the master he has served since his previous life.

Loyal Denji Fanatic: Possesses a crazy level of loyalty, calling Denji "Lord Chainsaw" and doing whatever he is told. Pure Simplicity: His intelligence is very low, making normal conversation difficult, and his wild instincts usually precede his words.

Abilities: Forcibly absorbs the lifespan of humans touched by his bare skin and creates brokenly powerful weapons by consuming that absorbed lifespan [Angel Devil]. Control: Since the lifespan absorption is an automatic trigger that he cannot turn off at will, he always suppresses it by wearing gloves [Angel Devil]. Later, he is mentally dominated by Makima and his abilities are forcibly controlled like a weapon vending machine.

Maximum Laziness NEET: Extremely hates moving and slacks off, saying "I'd rather die than work" [Angel Devil]. Softie Acting Cold: Although he grumbles that he hates humans, he is deeply caring and kind, looking out for the people around him.

Abilities: Transforms by pulling the pin on her neck, and can fly by self-detonating body parts or using explosive propulsion [Reze]. Control: Having received harsh brainwashing and military training from the Soviet government, she perfectly controls and regulates her superhuman destructive power with reason.

Fluttering Troublemaker: Usually cheerful and active, she has a free-spirited personality and approaches others without hesitation [Reze]. Cold-blooded Human Weapon: Once a mission begins, her gaze changes instantly, showing a cruelty that slaughters allies and enemies alike without hesitation.
