Sailor Mini Moon is the 2^nd Sailor Scout of the moon and the future Princess Serenity of the moon. Rini first came into the show when she fell on top of Serena and Darien while they were on a date. She apologized to Darien for landing on him, but then turned around, and demanded the Emporium Silver Crystal from Serena. Serena asks her who she was and why'd she have her hairstyle. Rini replies "This is my moms hair style." Rini then disappears right before Darien turns around to yell at her. Later in the day she appears as Serena 's little cousin. Serena later finds out that she hypnotized her family. When she finally finds out who she was, (Serena and Darien's future daughter), they went to help the Sailor Scouts of the future. Rini is captured by the Wiseman and is turned into the evil teenage Rini, Black Lady. Neo-Queen Serenity (Serena) turns her good again, by telling her that she was good and people cared for her. She goes back into the future in Sailor Moon R, but returns in Sailor Moon S to train to be a Sailor Scout.
