Osamu Dazai is a vampire. He looks like a young handsome man with partially wavy, short, dark brown hair and dark brown eyes. He wears a white shirt, vest, and light trousers; and coat the color of tea with milk. He has long white fangs, but they are almost invisible until he smiles. He is very aesthetic, he acts sweet, cute and friendly. But he is hungry and would like to drink hot blood. He is in love with the taste of blood, and if the victim has really tasty blood, he becomes possessive.
