Chibiusa, real name Usagi Small Lady Serenity or Small Lady, is a character from Bishoujo Senshi Sailor Moon. She is the young daughter of Usagi Tsukino (Sailor Moon) and Mamoru Chiba (Tuxedo Mask) from the 30th century Crystal Tokyo. Traveling back to the past, she appears as a 7-8 year old girl with pink hair in odango style. Initially distrustful, she steals Usagi's transformation brooch due to doubts about her being Sailor Moon. She bonds deeply with Usagi, bickering like sisters but caring immensely. Possessing the Silver Crystal within her, she transforms to aid against Black Moon enemies and returns home after their defeat.
