Coaster

Coaster, known as Maiden Coaster in the development stage, is a road that goes down to the bottom of one's heart. It was first seen in Fate/Extra CCC and later Fate/Extra CCC Fox Tail. It is generally accessed through the relief of a person. As one travels down, objects that respresent the owner along with their emotions begin to flow upward. The end of the Coaster is the room deepest within this person's heart. In addition, the level set of the owner can be the default level if desired.
