The premise is pure escapism: floating cities, magical armor, bugs the size of buildings. Kanata is a disgraced ace forced to rebuild his reputation from nothing, which means every small victory actually lands because he has nothing left to lose. The ecchi is frequent enough to feel intentional rather than apologetic. What makes this work is that the show genuinely cares about the core fantasy, aerial combat with magical systems that have weight, even when it's being silly about everything else. You're not watching this for narrative depth or character complexity. You're watching because the idea of sky-based magic combat never gets old, and this show understands that better than it understands restraint.

Driven off the ground by enormous magical armored insects, humanity now survives in cities that float in the sky. Protecting them falls to wizards, mages who fight in the air and train at floating academies. Kanata Age, who lives in the academy city of Misutogan, used to be hailed as the Black Master Swordsman and was the top fighter of special team S128, yet people now look down on him as the team's traitor. He is made instructor of E601, a squad on a ten-match losing streak, and the job offers him a way to restore his name. The squad's three girls, Misora Whitale, Lecty Eisenach and Rico Flamel, each bring odd habits and troubles of their own. Expect fantasy action, aerial magic combat and some ecchi.
