Never heard of the anime, but I looked it up. The only similarity (from the summary of the plot and ending) is that you die and are reborn. Not trying to say that my idea is completely original (never really said it was lol), but I'm sure there're plenty of plots, in stories, with the concept of rebirth. If there's something I missed, please let me know. The world starts out as a normal slice of life anime, until you get contacted by the unknown individual.  Also, would it really matter if it's on the 1x1 or advanced forum? I put it here so I could get attention from people looking for an advanced roleplay, who aren't looking at the 1x1 forums. I didn't realize my decision would affect others that much.
