I'm not usually mean on here, so I'll try to do this nicely:

You're going to ruin a great anime and great world setting here. You've admitted to knowing next to nothing about the series, and you and someone else planning to be in the group agreed upon something that is entirely wrong and you claimed to know it as fact. Not to mention you copied the whole intro directly from the Angel Beats! wiki. You're putting zero work into this and you're going to get actual fans of this excited and then let them down when you realize you can't keep going or they realize you don't actually know where to go. I suggest stepping down if you want an Angel Beats! game. Putting up a new interest check asking someone else to do it would also be a great idea. If you take nothing from this, then I hope your to-be players do. 

Again I'm not trying to be a dick or even an elitist, but I realize there's no other way I can come off here so I apologize for having respect for a story, I suppose.
