Once, this city was home to a magical girl who battled invaders from another world.

But she harbored a secret: he was merely a high school boy, only temporarily transformed.

Then, a dying blow from the enemy permanently turned him into a girl.

The world regained peace. However, her heart, now irrevocably transformed into a different person, grew embittered...

This is the story of a boy, her best friend, who endeavors to restore the magical girl to her former self, and the former magical girl—who was once a boy—who gradually finds herself growing fond of him.
