Also known as Sailor Moon, Usagi is a cheerful, friendly, lazy klutz of a girl who seems at first glance to be a perfectly normal suburban schoolgirl. In reality, she is the reincarnation of a princess who died thousands of years ago, when Empress Metallia brought an end to the Silver Millenium. Luna, one of that era’s few survivors, tracked down Usagi and gave her the pendant which allows her to transform into Sailor Moon. Usagi is pretty much the definitive reluctant superhero: she would much prefer boy-watching, eating ice cream and having fun with her friends to battling the forces of evil. However, she has demonstrated a remarkable strength of will and character when her back is to the wall and it is clear that she not only can, but must save the day. To Usagi, there is nothing more precious than her friends and family, and threatening either is sure to draw out her hidden reserves.
As Sailor Moon, Usagi has access to quite a few magical tricks. She gains increased speed, strength and stamina but not as much as the combat monsters of most martial arts series. Instead she tends to rely on her impressive magical attacks, which are the most powerful of all the Sailor Senshi and have been known to destroy monsters, ancient evils and other entities in a single shot.
Usagi lives with her mother, father and younger brother in a small suburban home in the Azuba-Juuban area of Tokyo.
