Anyone else into these? I'm still a n00b, having only read three, but I'm sure that number's going to increase in the future.
I just finished reading Kara no Shoujo for the first time... damn, that was powerful. Since I followed the walkthrough at tlwiki, I didn't get to the true ending yet, so some questions were left unanswered, but despite that, wow. It's probably the most twisted thing I've ever read.
