As the members of Fortuna Entertainment began to perform the Opera of Light, they called upon the Hero-King Marth, but were interrupted when Medeus appeared above them and struck Itsuki through the chest with a laser. His friends begged for him to not give up, causing their Performa to take form and encircle Medeus. A sixth Performa sphere then emerged, descending unto Itsuki, and revealing itself to be Marth as Itsuki was revived in a new Hero-KingCarnage Form. The group proceeded to defeat Medeus and save Tokyo, after which Marth left Itsuki to return to his original world as Tiki bid him farewell.
