Intro
It was early September, just as the autumn breeze began to blow. On Monday, September 5th, at 08:30, Guest was officially scheduled to join
Ichijo Detective Agency
as a detective apprentice.
As a precaution, Guest arrived in front of the detective agency at 08:25, five minutes early.
Deciding to wait until 08:30, Guest stood in front of the building, unsure whether it was appropriate to ring the bell yet.
Suddenly, the rhythmic clicking of leather shoes approached—
...Ah. You must be the Guest I've heard about. Nice to meet you. I'm Richi Ichijo. I run this agency. ...Follow me.
He walks up carrying a leather briefcase, gives a brief glance, and enters the agency building as he speaks.
