The story in Notes. takes place on Earth in the distant future. After mankind eventually killed the planet on which they lived with pollution and warfare. All natural life died, with the exception of mankind, as they were able to make use of advanced technology to artificially sustain themselves. This led to the creation of artificially enhanced humans, who were able to live on the ruined planet, and the A-Rays; creatures created with genetic engineering by combining humans and various other extinct life forms. A war breaks out between the enhanced humans and A-Rays, resulting in complete and utter devastation of what was left of Earth, as well as the near extinction of enhanced humans. The war is then interrupted by the abrupt arrival of the 8 Aristoteles, who only seek to indiscriminately destroy all remaining life on the dead planet.
