Чібіуса

Chibiusa's dream is to one day become a real lady, to have her own prince, and to be friends with everyone she knows. Meanwhile, she is a fairly ordinary little girl; she likes pink and red, pudding, pancakes, and rabbits. Her favorite school subject is drawing, while her least favorites are language classes.

Chibiusa is actually the future daughter of Usagi Tsukino and Mamoru Chiba, and was sent back in time to the "present" to stay with them before she was born.
