It is nighttime in Tokyo, Japan, and Aki has just gotten off work. He had had a long day killing devils, and it wasn’t that they were strong devils he had been sent to kill. There were just a few weak devils grouped together.

He sighs and leans up against a tall brick building, right outside of the Public Safety Devil Hunters' headquarters. Taking out a pack of cigarettes from his pocket, he taps on the box before taking one out and lighting it.
