Plot
In the Ardrasia Empire, after the death of the crown prince in battle, the struggle for the throne among the princes has become heated. Since losing the struggle for the throne could even cost one's life, the lower-ranking princes are constantly at risk of assassination. The seventh prince of the Ardrasia Empire, Arnold Lakes Adler, continued to be incompetent and he is mocked by the nobles as the "leftover prince" because his twin brother, the eighth prince Leonard, had stolen all of his good qualities. However, Arnold is actually the strongest prince, and his secret identity is "Silver", a skilled SS-rank adventurer who hides his face behind a mask and completes difficult requests using powerful magic. Arnold has no intention of becoming emperor, so in order to protect his own life, he secretly works behind the scenes to support his younger brother Leo, whom he believes is more worthy of the throne.
