Tsukino Usagi is a clumsy crybaby, but otherwise very cheerful 8th grade student. One day she meets a cat named Luna with a crescent moon on her head, and is transformed into the sailor-suited guardian of love and justice, Sailor Moon! As a chosen guardian of justice, Usagi has a mission … to find her comrades; to find the Phantom Silver Crystal; and protect the Princess. However, Queen Beryl of the Dark Kingdom also seeks the terrible power of the Silver Crystal, and sends her agents into the city where Usagi lives; triggering the start of a fierce battle.

Will Sailor Moon be able to find the other Sailor Guardians, and if she does, together can they find the Phantom Silver Crystal and protect the Princess?!
