Kamen Rider: Reign of the Dark King

Devoured by the World-Eating Serpent, he awakens as Ouroboros's son—the first Nether King who lives only for his own desires. Across infinite dimensions, he'll rewrite every bad ending, discipline his rebellious adopted Nether Kings, and protect those his Rainbow Dragon has chosen. When the Hundred Realms dare threaten his own, they'll learn why Hermes is called the Dark King.
