Thanks for posting those pics .. I'm missing this show.
By the way, I sort of getting, from those pics, the vibes of Yoshino / Hakaze, Mashiro / Aika pairings. Pairings I'm not actually buying, because for some reason I tend to doubt each hint this show gives away
Anyways, Aika is the mystery girl of the year. She is probably even better than Misaki Mei.
