Chikage Kazama

As the most powerful Oni in the West, this arrogant Bakumatsu member serves as a primary antagonist to the Shinsengumi. Driven by a mysterious desire to breed a superior generation, he relentlessly pursues Chizuru to claim her as a mate. Though accompanied by his loyal subordinates, Amagiri and Shiranui, his motives remain ambiguous, even when he briefly acts as Chizuru's protector. His transformation reveals striking white horns and yellow eyes, hinting at a potential royal lineage.
