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 since he created this world, he can name and modify it to whatever comes in his mind.

He believes he is alone in his own world and no one can enter it other than Aoi himself, but one day there appeared an energetic boy covered in bandages much to Aoi's astonishment. 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".
