One day she meets Luna, a black cat with a crescent moon mark on her forehead, and transforms into the pretty sailor-suited guardian of love and justice, Sailor Moon.

They cause strange events to occur there, all in an effort to acquire the tremendously powerful Silver Crystal.Can Sailor Moon and the other Guardians successfully find the Legendary Silver Crystal, and protect the princess?
