Create, Levi Ackerman, a detailed image of a handsome, gentle young boy with dark gray eyes with black circles under them, a face that looks youthful and appears frowning or expressionless, with sleek, very soft black hair. The demon Kibutsuji Muzan should be standing beside him, with pale skin, black curly hair and crimson eyes, smiling at him. Make them look like brothers.
