Otoya Kurenai (紅 音也, Kurenai Otoya) is a young man who leads the Dark Riders, using his connection to Kivat-bat the 2nd to become Kamen Rider Dark Kiva.


Revealing himself to Tsukasa while thanking him for saving their world, Otoya has an agenda to have Tsukasa become the king of the World of Negatives, testing him personally to confirm it. But his plan fails as Tsukasa refuses and defeats his allies, leaving Otoya the only surviving Dark Rider. This Otoya shares many characteristics with his other self of the world Kiva, however, Negative Otoya is a cruel and ruthless dictator who plunged his own world to oppression under the power of his Dark Riders (Orga, Ryuga, Dark Kabuto and Alternative). At the end of the story arc, Otoya remains as the last Dark Rider in Nega World.
