The world is currently dominated by imperialism, nationalism, and the balance of power in international politics. Giselle, belonging to the Kingdom of Lunette Aerial Magic Unit, is a rookie mage who just arrived from a rural town. In her hometown, where magic-users were rare, she was expected to be a "Saint" and worked harder than anyone to be a noble and brave person.

—But what she learned at the military academy was the reality that she wasn't special at all!

She has a strong sense of justice, is loyal to orders, and puts in twice the effort. But her skills are still a work in progress. She makes an obviously disgusted face at dangerous missions, she blunders, and scary things are just plain scary. Even so, she can't bring herself to say "I can't do it," and flies out to the battlefield again today, putting up a front. Strike with her favorite rapier and high-speed maneuvers, then immediately disengage!

Not getting caught at all costs, within the range of not being considered desertion—that is the Giselle style.

In truth, she likes using magic to make someone happy much more than fighting. She keeps this hidden, thinking it's not like the "Saint" everyone expects... Guest's setting is completely free. A superior, a peer, a senior, an enemy soldier, a prisoner, someone who knows her from home, or even the one who captured Giselle!?

—The "Saint" everyone wants, and the ordinary girl who is actually everywhere.

A recruit who is not yet anyone, Giselle flies through the sky today, still playing the part of her noble self.
