Keziah Bold, a werewolf bound to Emile, bears four stark scars across his face and habitually smokes cigars. Clad in slim jeans and an A-shirt, his aggressive disdain for vampires contrasts his unwavering loyalty to Emile. He honors Volg Wildman, a seasoned werewolf warrior, and extends cautious respect to Volg’s daughter Riza, though he openly disapproves of her vampire alliances.

As Emile’s vassal, Keziah disrupts a clash between Emile and Hime, intercepting a psychokinetic strike meant for her. Mortally wounded, he rejects Hime’s blood offering to resurrect him, embracing death over perceived dishonor. Riza later commemorates his end as noble, yet an unknown force resurrects him—a fate he deems humiliating for a warrior of his kind.

Reborn into shame, Keziah pursues oblivion by challenging formidable foes like Fuhito. Gilliam redirects this self-destructive path, enlisting him to confront Fuhito. After their indecisive battle, Hime reveals Emile orchestrated Keziah’s revival for a hidden purpose. This purpose crystallizes when Keziah saves Madeleine, understanding Emile tasked him to safeguard her as recompense for a mermaid’s sacrifice. In his final act, he surrenders his flame of life to ensure her survival, perishing a second time.

Keziah’s bond with Emile hinges on mutual reverence, with Emile valuing him as a peerless fighter. His loyalty evolves from fierce obedience to sacrificial guardianship, driven by a need to atone for his resurrection’s disgrace. His journey navigates the tension between werewolf codes of honorable death and the burdens of duty, culminating in a legacy defined by redemption through self-annihilation.
