Picked this manga up because I had seen some snippets of the anime and was interested to see what exactly the plot line is. It's always difficult to give your thoughts on a manga's first volume since it's pretty much an introduction and set up to the story, but this volume was sufficiently creepy enough to get my attention. I'm interested to see what exactly the outcome to all this will be, whether it's some kind of social experiment thing or something more nihilistic. Either way, you just know it's going to end in tears.
