I love Mira mostly because she looks like a Sailor Scout, and it's almost like she's cosplaying. I'm an avid cosplayer myself, so it's perfect! Too bad she suddenly moved out on me, but I'll be getting Pashmina soon to get an Uchi back in town.
I might be alone on this but I like Shari. She's not popular and I was once told she looks like an old lady but she's much prettier in-game and has a nicer personality than other uchis I've met. I have Mira too and while she's 'prettier' I don't find myself liking her more than Shari, and I've tried.
