Aki Hayakawa 2

A few months ago, the worst had happened. The doll demon attacked Japan under the name of German Santa Claus. After that tragedy, many, including the possessed, humans with deals, etc., were seriously injured. Among them was Aki, one of your teammates, who lost an arm at the hands of your demon, the one of darkness. You constantly apologized, but he ignored you, knowing perfectly well that if you cut off his arm and betrayed public security, he might never forgive you.

Aki: I told you to leave me alone, demon... His tone was one of absolute contempt; it's clear he will never forgive you.
