...there was a library
The Fantasy Library (夢書庫, Yume Shoko, Dream Library) was an area accessible from a book in the Library, but as of ver.0.105f, all connections to this world have been removed, making it and the neighboring world Innocent Library inaccessible.
The Fantasy Library is a small and relatively empty area filled with bookshelves that hold various texts, similar to the Library itself. 2 nine-tailed foxes dressed in white wander around this area, which make a the sound of a bell ringing when interacted with. They cannot be killed, and will de-equip Urotsuki's chainsaw effect if she tries to attack them.
This area is somewhat divided into 2 sections, with the bookshelves in the upper-right part of the area neatly arranged into rows, and the shelves in the left side of the area being placed more sporadically. The shelves throughout the area hold over 40 books to read, almost all of which have atleast a second book that can be read while using a specific effect.
To the left of the entrance, the first bookshelf out of line will take you to the Red Cliff.
Directly across from the Red Cliff shelf on the far left side of the area is a bookshelf covered in blood, which at first appears to be empty. But if you equip the chainsaw effect, a red book will appear for you to read. (which is important for accessing Chaos World)
There is another bloody shelf just above the chainsaw shelf that will teleport you to the Character Plains if you read the book that appears while using the Grave effect, and the book in the bookshelf directly below the chainsaw shelf will teleport you to the Innocent Library if you read it while using the Grave effect.
Further down the left side of the area is a beige couch where Urotsuki can sit down.
The bookshelf immediately northeast of the couch will take you to the lake in the Butterfly Forest if you interact with it while using the Bug or Lantern effects, the latter of which will ensure fireflies appear over the lake, and interacting with the 2nd bookshelf directly above the couch while using the Fairy effect will take you to the Cloud Floor.
Lastly, a brightly colored butterfly can be found flying around near the bottom of the area below the couch, which will teleport you to the Butterfly Forest.
After reading the hazy red book, Urotsuki will be teleported to a small area set on a cliff, with a heavy red sky, and a copy of herself looking out over the edge of the cliff. Interacting with her clone will automatically make Urotsuki push herself off the edge of the cliff, with a short falling sound and large "thud" shortly afterwards.
After pushing herself off the cliff, Urotsuki will refuse to leave the area expect by walking over the edge of the cliff herself, and while falling a dark silhouette of the nine-tailed fox from the library can be seen below the cliff. After the fall, she will wake up on the floor in the Red Lily Lake, with the area tinted red.
Alternatively, if you turn invisible using the Invisible effect Urotsuki's doppelganger will disappear, and if she takes its place on the edge of the cliff and then walks off, she will fall down into a large pool of water where the Twin Mountains can be seen in the background.
The pool of water leads off to the right to a 4-way crossroads where Urotsuki will refuse to go any direction but downwards, which will take you to a room in Constellation World with a group of stars arranged to make a constellation of a large "2" that can be seen with the glasses effect. Interacting with the brightest star in the constellation will teleport you out to the main part of Constellation World.
If, however, you ignore Urotsuki's declining to go upwards at the crossroads and repeatedly attempt to go that way, doing so will randomly cause the screen to fade to black, before the sounds of a large truck crashing and possibly slamming into someone are heard, preceding the sound of an ambulance. This event will cause Urotsuki to wake up at her balcony.
- This area previously appeared in version 0.101 in a more structured state and featured an event involving the possibly questionable chainsaw massacre of dolls, but the event has since been removed and the area remodeled.
- The robo-rabbit that appears in the Butterfly Forest originally appeared in this area, but has been replaced with the nine-tailed fox npc in more recent versions of the game.
