By joining forces with the various armies of the Magic World, the members of Ala Alba storm Cosmo Entelecheia's stronghold where Asuna and Anya are being held captive, to stop their plans. During the confrontation a magic gate is opened to Earth just above Mahora, having Negi's remaining students who stayed behind along with the Academy's faculty members joining the fight. After rescuing Asuna and convincing Fate to accept a plan to save the people of the Magic World without the need of any sacrifices, Negi discovers that the true leader of Cosmo Entelecheia is none other than his father Nagi, possessed by the Mage of the Beginning, who vanishes after asking his son to look for him and release him once and for all.
