Cooan, called Catsy in the NA dub, was the youngest of the sisters. She wore a pink and purple tutu, and wore her hair up in the shape of cat ears. Her power was Dark Fire, and she corresponded to Sailormars. Naturally, she fought Sailormars in the her episodes. Catsy seemed to be the most energetic and enthusiastic. She pretended to sell make up to the girls, and then invaded a martial arts class Grandpa was holding. She was the first to be healed -- Rubeus rejected her after she 'failed,' and gave her one last chance with a bomb. She would just need to blow up the world. But Sailormars defended her when the rest of the senshi were going to annihilate her, and she was healed. I love her because she is hilarious and because she is bold. She worked harder than her sisters, and she worked diligently and constantly. Her utter devotion to Rubeus was rather sad, because he didn't love her. I also think her hair rules!
Beruche, called Birdy in the dub, was the second youngest Akayashi sister. She wore an outfit rememniscent of RuPaul -- sky blue thigh-high boots, a body suit that was quite low cute, and gloves (gotta respect her for that). She wore her light blue hair in a braid in the back, and then wrapped a small braid under har bangs. Her attack was Dark Water, and she corresponds to Sailormercury. And yes, she did fight Sailormercury. Beruche plays chess well, and in one fiendish plan, hijacked a chess tournament. Beruche also wears these very cool Scarlor-O'Hara outfits, complete with parasols. While Cooan usually fought herself, Beruche commanded various droids. She tried to take over various crystal points (an ice cream store, a make up store, etc) but, of course, failed. She, too, was kicked out of the Dark Moon Family and healed by Sailormoon. I like Beruche because of her outfits (her frilly frou-frou ones) and her general coolness throughout her brief period of showcase.
