Deadman Wonderland vol. 1

I couldn't find a picture of the cover online so sorry. This was a really good story I thought. The main characters were interesting, and I'm curious to see what happens in the next volume. I've seen some reviews around of people comparing it to Elfin Lied, but I haven't properly finished watching that show so I can't really compare them. I will be looking forward to reading volume 2 coming out in June.
