Music Room Endings
These endings can be seen by collecting over 95% of the game's music, going into the music menu, and listening to some tracks. When you exit the Computer screen, you may be returned to a variation of Urotsuki's Room, with the curtains drawn, blocking the balcony, and the front door open. Exiting from the front door at this point will take you to the music room, with a phonograph and a bed in the middle of the room.
