Lore[]
According to his official website, Kain is a pure-blood vampire born into the Rifonist lineage.[4] He upholds the laws set by the Vampire Council and maintains the balance between vampires and humans.[4] He travels across the globe to enforce order and investigate disturbances that threaten their coexistence.[4] Despite his responsibilities, he finds solace in music, which provides refuge from his eternal duties.[4] Kain respects tradition but rebels against archaic rules and sometimes clashes with conservative members of vampire society.[4] He is fascinated by humans and forms friendships and alliances with them, broadening his perspective.[4] Driven by an intrinsic need to protect those unable to defend themselves—whether human or vampire—he strives towards a future where peace might be possible.[4]
Personality[]
Kain combines aristocratic charm with a gothic edge. He is polite and formal, addressing viewers as guests and maintaining his vampire persona.
