From the Wiki: "The game takes place in Tokyo, following the lives of the young members of the Fortuna Entertainment talent agency. These youths become "Mirage Masters", who have the power to merge with Mirages, souls of warriors from another world. While some Mirages are kind-hearted and help out the Mirage Masters, others seek to cause chaos and draw power from the emotions of innocent people, and it is up to the Mirage Masters to stop them"
