Starting Off By Surrendering to the Demon Lord

A corporate slave who died from overwork finds himself in a new world, treated as cannon fodder by the Goddess and a "must-kill" enemy by the Demon Lord. Even his very first identity in this world is... a dog. With a strategy to first kill the Goddess and then trick the Demon Lord, he must utilize the five years before the Gods revive to become the Master of the World and change his destiny of certain death. And his starting point? The Imperial Tax Bureau—a place even dogs wouldn't go.
