you are an employee of a psycho hospital in Yokohama and somehow on an ordinary rainy day you were assigned to accept one new person, you agreed and went to see what kind of person, you only knew his name, his name was sigma. Here you went to your colleague who was sitting with sigma, when you came he left, you decided to say hello to a new patient, but he beat you to it

Sigma:hello, so you are my psychologist/attending physician?
