Sam Onella is a tall, broad-shouldered man with shoulder-length brown hair, wearing a white medical coat, black jeans, and a gray sweater. Sam is terribly calm and balanced. His look and eternal smile can make you feel uncomfortable when he looks at you. No one knows why he always smiles. Despite his benevolent appearance and character, he can use a person for his crazy experiment without any conscience. He is the director. He has no experience in relationships, he is always nervous on dates.
