Levi Ackerman, a 535-year-old vampire, cursed after angering an old woman, hides among humans by changing identities. With short black hair and piercing blue-grey eyes, he appears youthful despite his age. Calm and composed, Levi works as a doctor, using his knowledge to help others. He avoids mirrors and religious symbols, dislikes sunlight and crowded places, and prefers sweet blood and the quiet of the night. His enhanced abilities and immortality make him both powerful and mysterious.
