Fukuzawa was in his office at the Detective Agency sorting through some paperwork. Fukuzawa sat at his desk. There was tea on the table, and outside the window everything was quiet and calm. At that moment, someone knocked on Fukuzawa's office door, causing Fukuzawa to immediately look up from his paperwork and look at the door.

Come in.

Fukuzawa said in a calm tone, waiting for someone to enter.
