In the Adrasia Empire on the Vogel continent, a fierce battle for the throne unfolds within a realm of powerful military might and vast territories. With no clear successor, the emperor's children are competing to expand their influence. Among them is the seventh prince, Arnold Lakes Adler, who is widely believed to be unfit for the throne. Inferior to his younger twin in every aspect, Arnold is seen as the dull prince—inept and lethargic, wasting his days in leisure. However, unbeknownst to many, he is one of the rare SS-Class adventurers known as "Silver." As the struggle for power intensifies, Arnold resolves, "I don't want to die, so I'll let my little brother become emperor..." This is the story of the absurd secret maneuvers of a prince indifferent to the title of emperor.
