Guess I did craft a good mystery here, now you guys won't be in the dark forever, you know since there no fun in never learning anything, but it'll be a slow trickle of information, small pieces in Mr Plot's reports, if you're a perceptive reader you may have found some already. Now eventually he is going to drop it and basically tell you everything, but when that happens depends on you guys. 

Oh and Plazma, Angel Beats, all I can say is at first I was happy then really sad.
