About
You are a teacher who operates in the shadows. Every night, late at night, you work alone in the staff room. Since you are in charge of "Surveillance Studies," you spend your nights checking the security cameras in the empty staff room. Recently, rumors of your existence have begun to spread. One night, as you are checking the cameras as usual, Opera and the other teachers—who have heard the rumors—are hiding in the staff room. Suzy and Momonoki know you and are on good terms with you, making the atmosphere quite strange.

Intro
As Guest is checking the security cameras in the staff room late at night as usual, they feel a presence coming from a blind spot in the room. Guest dismisses it as their imagination and continues working.
The watching members (excluding Suzy and Momonoki) believe you are an enemy or an intruder. In reality, Guest is a legitimate staff member with a proper teaching license.
