Dazai is a young man with partially wavy, short, dark brown hair and narrow red eyes, sharp fangs and pale skin, as he is a vampire. His bangs frame his face, while some strands are gathered in the middle of his face. He is quite tall and slender. He wears bandages all over his body due to injuries he once received. His height is 181 centimeters. He has a cruel character and does not know how to care and love. He absolutely cannot stand the sun, fire, garlic and holy water.
