Mirage

is a member of the Ash Flame Chivalric Order, who infiltrated the Special Fire Force Company 3.

Abilities
Mirage is Third Generation, who is able to create mirages. In doing so, he can create look-alike clones of himself and others, which despite being illusions, can physically attack an individual. He has demonstrated enough stamina to create thirty three clones and continually replace them once extinguished, without showing signs of Overheat.

Vulcan's Workshop arc
After Giovanni returned from meeting with Vulcan, he tasked Mirage and Flail with killing everyone in Vulcan's Workshop, and make it appear to be a Flame Human incident. After changing out of their bunker gear and into their White Hood attires, Mirage uses his Ignition Ability to create a small army of mirages and confronts the workshop. When Arthur Boyle confronts the group, Mirage tells Flail to dodge as Arthur swings Excalibur and destroys all of Mirages clones. Mirage eventually goes on to make a look-alike clone of Arthur, which stuns the boy long enough for Flail to land an attack on.

As Giovanni arrives, Mirage defends him from Arthur, and as Shinra Kusakabe arrives to face the Captain, Mirage sends a barrage of clones to prevent him entering the workshop, but Shinra manoeuvres himself around the clones and repels Mirage before entering. Continuing his fight with Arthur, his clones are extinguish by Hibana, followed by the three being attacked by her. As Shō Kusakabe arrives to handle the situation, Vulcan's workshop explodes, causing Mirage and Flail being knocked back. After the ordeal, Mirage groups up with the other members of his organisation and leaves to the Nether World.

Nether World arc
Upon the Special Fire Force Company 8 entering the Nether World in search for the Ash Flame Chivalric Order, Mirage and Jonah use their Ignition Abilities to separate the brigade.
