Kirino is, um... Yeah. /not gonna continue with this series 'cause not too interesting
I honestly thought Kyousuke was voiced by the guy who voiced Touma, but it turns out it was Tomoya's/Gray's seiyuu instead. So different-sounding (sob), but then that's a sign of a decent seiyuu. Kirino's seiyuu, on the other hand, I was able to figure out as the person who voiced Mio in MM! because they basically sounded the same.
/tendency to look up seiyuu for the win
