|Rainbow Silhouette World|
Rainbow Silhouette World (きらきら, Kirakira, Glitter) is an area accessible from Old Train Station B.
This area is characterized by a huge rainbow vine frame, which constantly surrounds your field of vision. Urotsuki herself only appears as a black silhouette against the bright scenery, and as she walks, prismatic footprints will form on the ground behind her.
The area itself contains colorful scribble-like plants, fishes, and trees. All of the objects in this world, except for the entrance tunnel which leads back to the train car, are presented this way, including a huge fish that gently floats through the air. To the east from the entrance, there's a giant clock with no hands. Southeast of the clock is a tunnel which leads to a huge, blue-tinted room that kind of looks like a zoo where you'll see some small cages and a big cage with a giraffe-like creature. Looking at this huge creature is a white-haired girl who somewhat resembles Urotsuki, suggesting that this world is a memory of something.
The huge dinosaur-like creature highly resembles the creature in Painter-Kun's painting in the Art Gallery. The resemblance is intentional, as 909, a poster in the original design thread, concepted both the zoo area in this world and Painter-Kun's area. (though, they concepted the zoo without any knowledge of when it would be added or where it would be added to, it was just a general idea for an area)
