I don't like Sailor Moon so Mira does nothing for me, Fuchsia is my favorite. Also I'm currently trading Mira in the villager trading forum for Doc, so if you're interested or if anyone here wants her, a trade would be ideal, but if no one has him I'll just give her away.
I say Fuchsia, I don't really like Mira's design to be frank (don't kill me).
Fuchsia looks like she's from the 80's and could be in a Tarantino movie, she's so cool.
I have both in my town and they are both awesome. As a Sailor Moon fan I would have thought I would like Mira better, but somehow Fuchsia wins by a slight bit. She is just so cool and chill. She is the perfect uchi.
I really like Fuchsia's house and she looks good in a lot of different clothes, while Mira basically looks bad in anything but the red zap suit. (And I just found out today that the red zap suit is "sporty", while Mira's favorite clothing style is "rock", so getting her to change back into it by mailing it to her is going to be really hard
Added bonus, in the Japanese version which I'm playing, Fuchsia's name is Jessica, pronounced "Jeshika" in Japanese. It's cute because "shika" means deer in Japanese!
