Mirage Masters are people capable of forming bonds with Mirages in the universe of Tokyo Mirage Sessions ♯FE. In exchange for some of a Mirage Master's Performa, his or her Mirage partner will lend them their power to aid and protect them. In battle, a Mirage will take the form of a weapon for their master to wield. Mirage Masters must hone their creative talents to strengthen their Performa and expand the abiities granted to them by their Mirages.
A Mirage Master may also merge with their Mirage, taking on a guise referred to as a Carnage Form. When in a Carnage Form, the Mirage Master's appearance will change dramatically, altering their clothing, hair color and style, and adorning their skin with markings.
