Runa is a normal fourth-grader at a school for foster kids, until one day, her world gets turned upside-down. Two fairy protectors come out of the woodwork and tell her that she's got a destiny of some sort, but she just doesn't want anything to do with it until her best friend gets kidnapped. She must then defeat the evil fairy and send him back to the fairy world, all while being in the fourth grade. The Girl Nerd reviews volume one of the manga, and discovers what she'd do if SHE had fairy powers at that age.
