After School - How to Unlock and Rewards

Once you have tracked the commission and arrived at the destination, approach the TV showing the inside of the school. Approaching it will transport you to an Anomalous Realm. There, explore the school and escape the realm to clear the commission.

The human-shaped silhouettes move and chase the player while not visible on screen. If caught from a blind spot, you will be sent back to the starting point, so move while keeping the silhouettes in view.

A key is hidden in the pot on top of the shelf in the hallway, so retrieve it. With the key, you can exit to the hallway on the opposite side of the classroom.

Once you exit to the hallway on the opposite side of the classroom, take the stairs up to the 2F. The silhouettes inside the 1F classrooms will not chase you into the hallway.

The silhouette right after going up to the 2F has a key hanging around its neck, so retrieve it. This silhouette also chases you when not on screen, so be careful.

Use the retrieved key to enter the office. The silhouettes in the hallway will not follow you into the office.

From the room with many desks, pass through the storage room filled with cardboard boxes, and move to the room at the back where a TV is placed on a desk. There are two human-shaped silhouettes, but neither will chase you.

Approach the TV and select "Look inside". Press the power button at the bottom right of the screen to turn off the TV and successfully escape, clearing the commission.
