When the hero and demon lord join forces, a unique rule is triggered in this world. An extraordinary angel appears suddenly, sharing startling news with the hero: "You now own 50% of the planet, which means you must pay a tax for this acquisition." This "strange policy" requires paying respect to the divine forces through taxes. The hero is taken aback by the huge tax owed on their immense wealth, covering "half of the world." In response, they hatch a plot with the demon lord and a young woman to create a false alliance and dodge the tax.
