I've been making it my business to watch all 200 episodes of Sailor Moon (the original version in Japanese), I think I'm in around the 140's.
And I happen to enjoy Chibi-Usa (Rini), she's just a little girl, y'know, an average little girl is a little mean and bossy. (I was like that too when I was her age lol)
But my favrite sailor scout of all time was Sailor Venus/Minako, she's more of a klutz than Usagi/Sailor Moon! Well, maybe not, but they're practially the same in denseness. XDD
