Forced to retreat to floating cities due to an invasion of magical armored insects, humanity must now depend on Sky Wizards to battle the menace via mid-air battles. Once known as the “Black Master Swordsman,” Kanata Age is now considered a traitor and is assigned to lead an F-class of mismatched mages. Misora Whitale has all the enthusiasm to be a leader, but she's failed 100 consecutive tests. Rico Flamel is a genius sniper, but she's a little self-absorbed, and Lecty Eisenach is a candidate with all the ambition but zero confidence. It's up to Kanata Age to train the troubled trio to become accomplished Sky Wizards.
