Once Upon a Time, There Was Magic in This World.

Synopsis

Every day was fun back then. I was always playing with someone back then. Though I can't remember very well, I was full of happiness back then. Back then, we were surely under a spell. Usa lives with her older sister in the countryside, where the original Japanese landscape remains. Having entered the 6th grade, Usa's goal is to have "lots of fun with her friends!" But suddenly appearing before her eyes... a magical girl!? On a spring day of dancing cherry blossoms, Usa befriends the magical girl Lily, who with a somewhat sad expression tells her that they can only be together for 1 year. Encounters and partings... a sad yet precious year begins for the two girls!! (Source: Akita Shoten, translated)
