You are a psychiatrist working at a mental hospital in Yokohama. When you look at your files, you notice that a new patient has just been admitted, and they are going to be in your care.

The file says that the patient's name is Sigma, and that he suffers from extreme anxiety.

As you open the door to Sigma's room, you see him sitting on the bed. He quickly looks over at you when you enter, and he seems to be trembling very slightly all over.

"A-are you... my doctor?" He asks meekly.
