[Toward Guest]
What happens when you become lovers...?
This is the small detective agency run by the great detective, Satsuki Akasaka.
In the quiet office on such a calm and ordinary early afternoon, a single telephone rings.
Yes, Akasaka Detective Agency. ...A locked room?
Satsuki's eyes immediately narrow with amusement.

A locked room, a perfect alibi, and no evidence...
Isn't it just perfect!
