Last aired: S1 E12, Final Battle! Leviatano · 2026-09-21

A low-ranking prince scorned as incompetent. His true identity is—the seventh prince of the powerful Ardrasia Empire. Arnold, the seventh prince of this empire, was known as the "Dust-Drained Prince" because his twin brother, Leonard, was so talented that he had sucked everything out of him. In the midst of the intensifying struggle for the throne following the sudden death of the first prince, who was the crown prince, Arnold decides to get serious, thinking, "I don't want to die, so I'll just make my brother emperor." While playing the role of the incompetent "Dust-Drained Prince" on the public stage, he secretly operates with overwhelming power as "Silver," one of only five SS-rank adventurers on the continent, and controls the struggle for the throne from the shadows.
