The Adrasian Empire on the continent of Fogel. In this empire, which controlled vast territories and had enormous military power, the struggle for the throne was raging. While the heir hadn’t been chosen yet, the emperor’s children competed, building up their strength. However, there was one prince everyone knew would never become emperor: the seventh prince, Arnold Leaks Adler. A young man who was inferior to his younger twin brother in everything—the “idiot prince.” Talented and apathetic Arnold spent his days idling and entertaining himself, but behind the scenes he was one of five SS-class adventurers, nicknamed “Silver.” Seeing the struggle for the throne growing more and more fierce, he decided: “I don’t want to die, so let my younger brother become emperor…” This is a tale of absurd secret intrigues by a prince who didn’t care about the emperor’s title.
