Even as our planet died, humanity survived; clinging to the smallest threads, adapting itself to survive the harsh new world. As the last pure human alive, the man known as the Gun God struggles every day just to survive in a world that is no longer his.

N.B. Angel Notes is a short 'story' of sorts by Nasu Kinoko. If you haven't read it you probably won't understand much of this fanfic. I highly recommend that you read the excellent translation by Evospace at Gaku Gaku Animal land.
