The House Over the Rainbow (虹家, Niji-ka, Rainbow House) is a small series of thematically similar areas accessible by crossing the rainbow on the Boogie Street.
Features
Once you enter the area, you will be placed at the beginning of a yellow path underneath a blue sky. Travelling down the stairs will take you to the entrance of a small house.
The interior of the house (家の中, Ie no naka, In the house) is a small, single-screen room that contains a small clock, a rug, and a bed. In the corner of the house is a staircase that will lead down to the Rose Field (薔薇畑, Bara hata), a small area consisting of a heart-shaped clearing in a huge field of colorful roses.
Equipping the Glasses effect in this area will cause all of the roses to turn black as if charred, and the music will stop. During this time the area becomes inescapable, forcing the player to unequip the effect to leave. A pot of similarly black roses will also appear on the glass table in the center of the area, that if interacted with will teleport the player to Black Rose World (黒薔薇, Kuroshōbi, Black Rose), an empty world with nothing but these same charred black roses. While in this area, you can equip the Rainbow effect to restore life to the roses; at this point, interacting with one will allow the player to return to the Rose Field.
