Angel Notes is a short story by Kinoko Nasu set After the End. It can be read here. A war between modified humans, A-rays and Liners, in the dead Earth now known as the Land of Steel is interrupted by the eight Aristoteles which start descending to the Earth after Gaia pleaded for them to hunt down the remnants of the human race. The story begins with "Gun God" Godo, as he flies with the remnants of his comrades above the troposphere, and defeats a winged Aristoteles with his gun that kills gods. Five years pass.
