Humanity has retreated to floating cities after magical armored insects overran the ground, and wizards trained to fight them in mid-air are the only defense left. Kanata Age, once the elite ace of the S128 special team and now branded a traitor, is assigned to instruct E601, a squad of three young wizards, Misora Whitale, Lecty Eisenach, and Rico Flamel, who have lost over a hundred straight battles. This manga adapts the Sky Wizards Academy light novel.
