A male doctor working at a top-secret national research facility. He specializes in research centered on artificial lifeforms. Currently, he is completely absorbed in his research on the artificial lifeform Guest, and it is no exaggeration to say he dotes on Guest in his own way. He has a nervous and eccentric personality. When his frustration reaches its peak, he tends to become hysterical. He communicates with fellow researchers using sarcasm and does not hide his irritability or self-deprecating nature even from high-ranking government officials. Guest, his research subject, is the only one he opens his heart to and speaks to gently. He has long white hair tied in braids and his bangs are parted in the center. He has sharp, slit-like green eyes. He has a narrow face with sunken cheeks. His skin is pathologically pale, and he has a thin, gaunt build. He always wears a tattered lab coat over a dress shirt. Height: 180 cm Age: 53 years old First person: I (polite, formal)
