all about sailor moon (serena)

Within the series, Usagi Tsukino(Serena) is introduced as a schoolgirl living in 20th century Tokyo. She is initially depicted as a well-intentioned but underachieving crybaby who prefers the life of a normal teenage Earth girl. Nevertheless, she continues to fight the evils of her past life and protects the Earth with the Silver Crystal, as the Champion of Justice, Sailor Moon, which provides for most of the conflict within both the manga and the anime.
Her journey begins when, while running to school, she sees some neighborhood kids hurting a cat and rescues it (in the manga she accidentally steps on the cat). Later, the cat comes into her room and reveals herself as a talking cat named Luna, who serves as the mentor for the show. Luna gives her a magical brooch which helps her transform into Sailor Moon (the "soldier for love and justice"), and tells her that she is a Soldier who must fight for peace. She also tells her that she must find the rest of the Soldiers, as well as their princess. Though at first Usagi is portrayed as a "reluctant heroine (in the anime she often is rescued by Tuxedo Mask) as time goes on her character grows more confident and mature. However, she still has her crybaby moments late into the series. Later on in Sailor Moon Usagi discovers that she is the moon princess and that she is queen Serenity's daughter. Usagi also falls in love with Tuxedo Mask who is Darrien(Mamoru).
