Colors ~ Aoi's Utopia ~

WELCOME to Aoi's space, world, utopia in which he called "Colors" despite being a colorless or plain white place.

But there's more to it. The boy knows Aoi, but Aoi doesn't know him. However, the boy just introduced himself as Aoi's "friend". Yet, Aoi claims he has no friends. AT ALL. His "peaceful" life suddenly disturbed by an unknown boy. Who is this boy? How does he know and relate to Aoi? More importantly, how did he enter Aoi's utopia?
