After being celebrated as heroes for stopping Cosmo Entelecheia, Negi and his friends return to the Academy, but instead of resuming his duties as a teacher, Negi leaves Fate as his substitute and with the help of some of his students he starts working on his plan to terraform Mars for the people of the decaying Magic World to relocate there. The plan involves sealing Asuna's body for one hundred years, and she bids farewell to Negi and the other students after she graduates from middle school. Waking up 30 years after the estimated time, Asuna finds that Negi's plan was a success and that Negi and all her classmates had happy and bountiful lives, but had long since died, all except for the immortal Evangeline, and Chao who exists in this time and has since invented a device to jump between realities. These two appear before Asuna to take her back to the present so she can live out her days with Negi and the others.
