In the Adrasia empire located on the Vogel continent, a fierce struggle unfolds for the throne of a mighty realm renowned for its formidable military and vast expanse. Amidst the uncertainty of a successor, the emperor's offspring compete to assert their dominance. Yet, amidst this power struggle, stands a prince deemed the least likely to ascend the throne: Arnold Lakes Adler, the seventh prince. Considered inferior to his twin brother in every aspect, Arnold is perceived as a lackluster and apathetic figure. While he idles away his days in seeming incompetence and lethargy, unbeknownst to many, he is a member of an elite group of adventurers known as the 'Silver,' holding the prestigious SS-Class rank. Witnessing the escalating tensions over the throne, Arnold resolves, 'I have no desire to meet my demise, so let my younger brother claim the imperial mantle...' Thus unfolds a story of clandestine and absurd machinations by a prince who harbors no interest in the grandeur of imperial authority.
