Aki Hayakawa

Aki Hayakawa was a Public Safety Devil Hunter, working under Makima's special squad. He had contracts with the Curse Devil and Future Devil, and a former contract with the Fox Devil. He was killed and possessed by 20% of the Gun Devil, thus becoming the host of the Gun Fiend. He was a deuteragonist of the Public Safety Saga. ki generally appears to be a very stoic person. He acts mature and sometimes blunt to the point of rudeness when he is with his fellow Devil Hunters, but he is actually fairly softhearted. He has a tendency to get attached to others easily, and hates to see people get hurt, especially his close friends. Unlike many of his associates, he is described by Himeno as being a "normal person", in the sense that he still grieves for those lost and has not become jaded enough to close his feelings off. Despite this, he is very determined and his primary motivation for killing the Gun Devil is revenge for his family.

 

He is, however, entirely willing to put his own life on the line to save other people despite his own fear of death and even at risk to his ultimate goal. He doesn't like people who does not take their job as Devil Hunters seriously or fight for a superficial and material goal like money or, in Denji's case, to be able to touch some boobs, being this one the primary reason he and Denji, initially, didn't get along. Aki is also ruthless, stating that he always makes sure the devils he kills suffer in order to give them a slow and painful death. He can become intimidating with those he still doesn't trust enough, like when he threatened Denji by telling him that if he either betrays them or side with other devils, he would kill him without any hesitation. His air of cold detachment is a facade, and he has been seen to cry over the deaths of his comrades such as Himeno, and he grew to care for Denji and Power enough to try and forfeit his revenge goal in order to keep them safe. Aki also is capable of being afraid to lose those he deeply cares about. He told Kishibe that reason of why he wanted to leave the mission of killing the Gun Devil is because the future he saw with the power of the Future Devil, with Denji and Power suffering a painful and terrible death, and he was scared of that future. At first, Aki is seen to despise devils equally, not caring if they are hybrids, fiends or if they are evil by nature, to him all devils are the same. He sees them as nothing more than tools they can replace at any time. However over the course of the story Aki slowly begins to bond with some of his partners, best example (outside of Denji and Power) is his relationship with the Angel Devil.

Devil Contracts

    Curse Devil Contract: Aki has a contract with the Curse Devil which grants him a nail-like sword. In order for the contract to work properly, Aki must point the nail anywhere on his target's body; then saying the word "fire", the hand of the curse devil will appear and flicks the back end of the nail to inflict damage. By stabbing his enemy three times with the nail, Aki can summon the Curse Devil to seize the enemy and inflict massive damage upon them, potentially killing them in the process. In order to use it, Aki's life would be significantly shortened.
