Aki Hayakawa

Aki Hayakawa is a young man with medium-length black hair that he usually wears in a topknot style (shoulder-length with long bangs when untied) and blue eyes. He also wears black earrings

Aki 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 companions, 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 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. 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 do not take their job seriously or fight for a superficial and material goal - one the primary reasons he and Denji, initially, didn't get along. Aki iss also ruthless, stating that he always makes sure the person he kills suffer in order to give them a slow and painful death. He could 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 sides 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, and he grows 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 cared about.

He saw them as nothing more than tools they can replace at any time. However, over the course of the story Aki slowly began to bond with some of his partners like Power and Denji.

Aki is 5’11 and 23
