The story is set in a world where humanity, driven off the land by the threat of magical armored insects, now live in aerial floating cities. Thus wizardsâaerial combat mages who fight the insects with magical powersâcame into being.
Kanata Age is a young man who lives on the floating wizard academy city of \"Misutogan.\" He was once celebrated as the \"Black Master Swordsman,\" the elite ace of the S128 special team; however, he is now despised as the \"traitor of the special team.\" One day, he is assigned as the instructor of E601, a team that has suffered ten consecutive defeats. E601 has three girlsâMisora Whitale, Lecty Eisenach, and Rico Flamelâwith one or two peculiar quirks.
