Edward Winston was an office worker who was playing an idle RPG game called Record of Aphoteosis. Using an account named “Noir,” he managed to become the first and only person to clear the final stage. But who would have thought that the final reward he obtained was a ticket called “Ticket Reverse Summon.” When Edward used the ticket, his entire world instantly changed. He was summoned into a world where Record of Aphoteosis was reality. In that world, it was not only him who had been summoned—many other humans were also summoned into that world. Starting over once again, Edward used all the knowledge he possessed to clear the game for the second time and return to Earth. [Welcome to the Aphoteosis System]
