Usagi first appears as a schoolgirl living in 20th-century Tokyo, a well-meaning but underachieving and accident-prone crybaby living the life of a normal teenage Earth girl. One day, Usagi encounters a mysterious cat, who later reveals herself as Luna, the mentor archetype who introduces Usagi to her new heroic role. Luna gives Usagi a magical brooch and explains how to use it to transform into Sailor Moon (the "Soldier of Love and Justice"); she tells Usagi that she is a Sailor Soldier who must fight for peace and find the rest of the Sailor Soldiers, as well as their princess. Though at first Usagi appears as a "reluctant heroine"[6] (in the anime she often is rescued by Tuxedo Mask), as time goes on her character grows more confident and mature. She sets out to fight the evils of her past life and protects the Earth with the Silver Crystal, as Sailor Moon, providing most of the conflict within both the manga and the anime.
