In the Adlasia Empire on the Vogel continent, a power struggle is brewing over the imperial throne. With no clear heir apparent and the emperor's children vying for power, one prince is deemed completely unsuitable for the throne: the seventh prince, Arnolt Rex Adler. Derided as a 'spent prince' who has been overshadowed by his twin brother, Arnolt is seen as incompetent and apathetic, a dissolute prince who spends his days in leisure. However, unbeknownst to everyone, he secretly holds the identity of 'Silver,' one of only five SS-class adventurers on the continent. Witnessing the escalating imperial struggle, Arnolt makes a decision: "I don't want to die, so I'll make my brother emperor." This is a chaotic story of a prince's machinations, who has absolutely no interest in the imperial throne.
