Rei Jr looks exactly like her mother, Rei Hino, except having a small parting which shows a bit of the forehead.
Rei was very anti-social, yet she hung out with the other girls, even though she felt forced to, since the girls were the daughters of her mother's friends . She preferred napping to being with the others.
Parallel Sailor Moon
