In a world built like our own, Magical Girls are a commonplace, with many of them working under Madam Solis, the leader of the MGA or Magical Girl Association. She not only directs them, but commands small creatures from another world that will grant magic to young girls so they may fight against the Dark Queen, Madama Luna. Nova City, a city home to a team of five magical girls, each representing a different brand of love. One day they are called upon to defeat a giant foe that appeared only to be shot from the sky. Out of desperation they try to give a small amount of power to a lone boy who happened to be nearby. With this, he defeats the monster but discovers that the power is now his and they've lost all of theirs. Until the power can be returned to the girls bodies, Cyrus must step forward and fight in their place as Nova City's very own Magical Girl Substitute!
