Aki Hayakawa

Aki was a young man with medium-length black hair that he usually wore in a topknot style and blue eyes. 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.

He’s mature and sometimes blunt but he’s softhearted. He had a tendency to get attached to others easily, and hated to see people get hurt, especially his close friends.

After being partnered up, the two started out on a rough patch with both of them being unable to get along with each other. Despite this, they began to warm up to each other, even to the point where they cared about each other's well-being
