Aki Hayakawa (早川はやかわ アキ Hayakawa Aki?) is a Public Safety Devil Hunter, working under Makima's special squad.[1] He has a contract with the Curse Devil and Future Devil, and a former contract with the Fox Devil.


Aki Hayakawa is a man with medium-length black hair that he keeps tied up on the top of his head. He wears a suit and tie. He also wears earrings and usually carries his sword on his back.


Aki has been shown many times to be a very stoic person. He acts mature and dependable when he's with his fellow Devil hunters, but the man is very soft whenever he's alone. After confirming his good friend Himeno's death through Denji and Power, Aki starts to cry, mourning for his fallen teammate. Furthermore, Hayakawa actually cares about Denji and sees the boy as a dear friend, despite the two of them having a mutual hate towards each other.



Intro arcEdit

When Hayakawa is first introduced, Makima orders Denji to work with him. While they are patrolling the city Hayakawa becomes annoyed with Denji asking whether Makima has a boyfriend and pulls him into an alley to beat him up, as a warning that if he doesn't take Devil Hunting seriously he could end up dead. Denji then fights back, kicking him in the groin multiple times and stating that he would risk his life to continue living the way Makima has shown him. Once they get back to the Devil Hunters Headquarters, Makima assigns Denji to Hayakawa's squad.

Devil ContractsEdit

  • Stab: Aki points the nail anywhere on his targets body, he then says the word "fire" the curse devil's hand appears and flicks the back end of the nail to inflict damage.
    • Curse: By stabbing his enemy three times with the nail, Aki can summon the Curse Devil to seize the enemy and inflict a curse upon them to kill them.

Future Devil Contract: After losing favor with the Fox Devil, Aki was taken to the Future Devil which is held prisoner by Public Safety, and he managed to gain a contract to use its abilities in exchange for letting the Future Devil live inside his right eye.

  • Precognition: Aki has the ability to see a few seconds into the future. He uses this to predict his opponent's oncoming attacks and plan accordingly.[3]

Former Devil ContractsEdit
