Here we go:
Kodaka - not voting for guys.
Yozora - good looks, but trolls too much, and often much too nasty.
Sena - we have a winner! Generally kind, good looks, likes to play eroge
Yukimura - not voting for "it", either.
Rika - second place, love her perverted antics
Kobato,
Maria - funny, but not interested in lolis.
Tenma - wtf? Who's that? Didn't appear in the anime, and she's not listed on AniDB either. Novel-only or something and thus shouldn't be on the poll.
Stella - only a short scene in one episode, too little. Also wtf at her wearing a male butler suit.
