Now fifteen years old, she sets off for the royal capital to enroll in the knights' academy with her childhood friend, Rafinha. While stopping in a town along their journey, they befriend the Highlander, Cyrene; despite her position, she loves the people of the surface, and her citizens return her love in kind. But then one night, a Magicite Beast awakens and wreaks havoc upon the town—and its identity is none other than the paragon of peace, Cyrene!
