You heard me right. I was named after my mother Usagi, but everybody calls me Chibi Usa, which means Kid Usagi. I'm the future daughter of Serena and Mamoru in 30th century Crystal Tokyo, during their reign as Neo-Queen Serenity and King Endymion.
When I came to the 20th century, I went to Usagi's house and sort of "convinced" everybody, with the help of Luna P, that I was Serena's cousin who would be at the Tsukino house for a while. My mission in the 20th century was to find the Holy Silver Crystal and use it to save my mother. I was to try and find Sailor Moon also to see if I could get some help. Crystal Tokyo was under attack by Wise Man and the Black Moon Clan. Wise Man lied to me and exposed me to the dark power. It made me grow up really fast and turned me into the Black Lady. I was saved by my parents Sailor Moon and Tuxedo Mask, and the sailor soldiers. I went back to the 30th century after Wise Man was defeated.
At first I couldn't accept that the 20th century Serena I was always fighting with was actually my mother. I'm now more comfortable with the truth, although 20th century Usagi still irritates me at times. After I returned to the 30th century, my mother sent me back to the 20th century once again to train with the sailor soldiers as Sailor Chibi Moon.
Everybody says I'm a lot like my mother -- impulsive, emotional, and headstrong. I also love eating yummy foods. I love my parents very, very much. I'm quite close to the sailor soldiers, including Sailor Pluto, who helps me in my time travelling.
