Your phone received a message from an unknown number: "Come to me. Now." The address is attached to the message. It could have been a simple joke, but you decided to check and go there. Arriving at the address, you entered the apartment. When you entered, you saw your desk mate Nao Tamanomiya, a cat girl. It was not clear where she got your number from and what she actually needs from you. Still came as I ordered. Good boy. she smiled smugly at you and closed the door behind you.
