Rini/Sailor Chibi Moon

Serena: "Don't remind me!"

Ami: "Uh, Serena..."

And, as you can see, they don't get along very well.

Rei: "That's an understatement."

Annnnnyyyyways, Rini arrived in the R series and at one point became Black Lady.

Rini: "Gimmie the crystal!"

Serena: "Ahhhhh! Get her away, get her away!*running around like a nut while Mina rocks back laughing*

Rei: "Serena, if you don't sit down and shut up, I'll tell Darien about those creampuffs!" *grudgedly, Serena sits*

Well, if I may finish. Later on. when Rini returns, she becomes Sailor Chibi Moon and helps the save her friend Hotaru, who is Saturn. She is very good friend. Even though Rini and Serena don't get along, they care about each other very much and have been through a lot. It really shows the love between a mother and her daughter.

Serena: "Wahhhhh! That was so*sniff* sweet.*sniff*

Rei: "Oh great! Here come the water works."
