This room is a space for the performers to rest and change their outfits.
The green room door on the left side of the Auditorium & Gymnasium is locked but the green room door on the right side is unlocked.
- The Green room of left side has a Fire-fighting equipment which was required to have scrapped item to operate in game. It also has an event but it causes the fire to spread more and therefore, the fire meter got worse. It is assumed that the Fire-fighting equipment purpose was to release the water for the valve pipe.
