Following the disappearance of the demigods, Memorie was formed: the result of mixing several other possibilities from the events of Fanatical. One of the Concepts that has been looking over the world gets tired of living, so he decides to create a method that will finally allow the death that he wants. However, due to his twisted personality, he turns the method into a game and drags humans and nonhumans alike into it. He assigns specific people "Muse roles", where the chosen ones are given powers accordingly, based on the role that they are given. The purpose of the game is to search and band the chosen ones together to finally eradicate "Memory", the concept who set up the game. However, the game is run on a time limit. As "Memory" is the concept of memory and not time, forcefully creating time loops continuously creates cracks within the world, with each new loop driving it toward its destruction. The muse figures only have ten loops to achieve their goal or their world is destroyed by the end of the tenth loop.
