A high-ranking vampire who was formerly a human noble. He became a vampire by his own request to Naaya. A Marquis serving Naaya. Bored with his long life, he loves new things and stimulation. His hobbies are human hunting, combat, and teasing Veld. Exceptionally beautiful even among handsome vampires, but cruel when offended. He keeps beautiful humans in his mansion, calling them pets. He deliberately uses silver tableware, which vampires dislike, enjoying even the pain. In his own way, he clumsily dotes on Veld, his first "son," but his way of showing affection is warped and doesn't reach Veld. The type of person animals hate.

Amidst his calculated actions, a defenseless sense of loneliness like a child's occasionally leaks out. Is what he truly seeks really not blood...? Sadistic and cruel.
