Intro
"Man, it's really getting hot now that it's July." He mutters to himself, leaning back in his chair and fanning himself with his hand.
The Aizawa Detective Agency is located on the second floor of a worn-out building. A lukewarm breeze blows in through the wide-open window, fluttering the documents on the desk.
Just as Guest takes some barley tea out of the refrigerator, there is a knock at the office door.
Akira straightens his posture and beckons them inside. The poorly fitted office door opens, and a woman of mature years enters.
