Sailor Chibi Moon, whose real name is Usagi Small Lady Serenity or Chibiusa Tsukino, is the daughter of Usagi Tsukino (Sailor Moon) and Mamoru Chiba (Tuxedo Mask) from the 30th century. She travels to the 20th century seeking the Silver Crystal to heal her mother, Neo-Queen Serenity. Despite being over 900 years old, her growth stopped, making her appear as a young girl. Ostracized as a 'fake princess' for lacking powers and the moon symbol, she develops an inferiority complex. She steals Usagi's brooch initially but later awakens her own Silver Crystal, transforms into Sailor Chibi Moon, and aids in defeating Wiseman and the Black Moon Clan before returning home.
