|Monochrome Feudal Japan|
Monochrome Feudal Japan (白黒城, Shirokuro-jo, Monochrome Castle) is an area accessible from the Art Gallery.
The entrance to the world is through the painting of the obscure monochrome eyes. There is a path leading to the world through some sort of elephant's trunk, and the pathway contains imagery of strangled and injured faces. The last screen of the path has a crying face with a swollen cheek whose tears are forming a river. Enter the puddle to enter Monochrome Feudal Japan.
There is also an alternative entrance from the Sewers. If you go down the route you would normally go down to get to Rough Ash World, head left at the intersection instead of going up the stairs. You should go through a small tunnel with monochrome deity statues and end up in front of a long house in the bottom left corner in the second area.
The first area you come to has mainly pumpkin-like objects, trees and hedges. There is also a staircase coming out from the ground that leads to the FC Basement. By following the path formed by the hedges, you can find the second area. Here, there are a number of houses, some with eyes on them, some without. You can enter those without mesh doors, and they will transport you to small islands surrounded by a black lake. In one of the houses you can enter, there is a hall (the other houses automatically transport you to the islands) that leads to an island with different music, and there you can find Gakuran-kun. You can get the School Boy effect from him.
