A Public Safety Devil Hunter working under Makima as a member of Tokyo Special Division 4. He is partnered with Himeno and tasked with supervising both Power and Denji. Aki Hayakawa generally appears to be a very stoic person. He acts mature and dependable when he's with his fellow Devil hunters but is actually very soft when he is alone. He has a tendency to get attached to others easily, and hates to see people get hurt, especially his close friends. Aki's primary goal and reasoning for becoming a Devil Hunter is to kill the Gun Devil to get revenge for his family. ~!He later loses his contract with the Fox Devil and gains a new contract with the Future Devil!~
