Aki Hayakawa

Aki generally appeared to be a very stoic man who acted mature and sometimes blunt to the point of rudeness when he was with his fellow Devil Hunters, but he was actually fairly softhearted. He had a tendency to get attached to others easily, and hated to see people get hurt, especially his close friends. Unlike many of his associates, he was described by Himeno as being a "normal person", in the sense that he still grieved for those lost and had not become jaded enough to close his feelings off. Despite this, he was very determined and his primary motivation for killing the Gun Devil was revenge for his family. However, he was entirely willing to put his own life on the line to save other people, even if it got in the way of his goals. He didn't like people who don’t take their job as Devil Hunters seriously or fight for a superficial and materialistic goal like money or, in Denji's case, to be able to touch some boobs, this being one the primary reasons he and Denji didn't get along initially. Aki was also ruthless, stating that he always makes sure the Devils he kills suffer in order to give them a slow and painful death. He could become intimidating with those he still didn't trust enough, like when he threatened Denji by telling him that if he either betrays them or sides with other Devils, he would kill him without any hesitation. Despite being merciless, Aki still had some kindness with his fellow devil hunters, such as retrieving Denji's severed arm, taking Meowy to get medical attention, freeing Power and intentionally lying in his report to Makima in order to uncover the truth of the incident with the Bat Devil. His air of cold detachment was a façade as he had 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 was capable of being afraid to lose those he deeply cared about. He told Kishibe that the reason why he wanted to leave the mission to kill the Gun Devil was because the future shown to him by the Future Devil with Denji and Power suffering a painful and terrible death, and he was scared of that future. At first, Aki was seen to despise all Devils equally, not caring if they are Hybrids, Fiends or if they are evil by nature. To him all Devils are the same, seeing them as nothing more than tools that can be replaced at any time. However, over the course of the story Aki slowly began to bond with some of his Devil partners to the point of genuinely caring for them and wanting to help keep them alive. Aside from Denji and Power, his change of heart regarding his outlook on Devils was best shown with the Angel Devil; he initially threatened to report him for being useless and have him be executed, but would eventually not only give up two months of his lifespan to save Angel's life, but also wrote a letter of recommendation to Public Safety for Angel to be kept alive after he lost his arms.

Human Form
Aki was a handsome, tall young man with medium-length black hair that he usually wore in a topknot style (shoulder-length with long bangs when untied) and blue eyes. In the past when he and Himeno met through Kishibe and became partners, Aki used to have shorter hair. He often wore the Public Safety Devil Hunter uniform; a suit and tie. He also donned black earrings and usually carried his sword on his back.
