Aki Hayakawa is a newly joined Public Safety member and is currently apart of Division 2. He joined Public Safety because he wanted revenge on the Gun Devil for killing his family. Aki generally appeared to be a very stoic person. He 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.
