Just pointing out that pics 023-026 aren't Azusa, but Otome Tsudzuki from Mayoi Neko Overrun. Yes, I'm aware that both characters look extremely similar, but aside from the bow usually tied at the end of Otome's hair (which could easily be missed since the word balloon's obscuring most of it), the author specifically pointed out this fact in the image's description on Pixiv. http://www.pixiv.net/member_illust.php?mode=medium&illust_id=10495574
