Urotsuki's Room is where the player resides while not dreaming. This room and its balcony are the some of the only locations Urotsuki can access outside of her dreams. Urotsuki refuses to leave the room by the door, and attempting to results in her shaking her head in a number of ways.
Room
Urotsuki's room is is pretty big, and she has a TV, Game Console, and a Computer, which implies she has better living conditions than Madotsuki. The view on her balcony shows a pair of peculiarly shaped mountains, with a large forest surrounding it, so she likely lives in a somewhat rural area.
As the player progresses throughout the game, many things will be added to urotsuki's room, if a little subtle at best. Most things that are inserted are seen after unlocking each Ending.
Dream Room
Urotsuki's Room Changes a little when she goes to sleep, her TV shows an assortment of strange images, and her computer shows a variety of different wallpapers.
