A spiritual doctor is a medicine man with spiritual powers who can cure both human and alien diseases. Due to the long-standing conflict between humans and aliens, spiritual doctors who hold a neutral attitude are neither allowed to be among the crowd nor accepted by aliens. The spiritual doctors who were once famous for their moral character and medical skills are gradually losing their former glory and prestige. The team of spiritual doctors is also shrinking rapidly. The remaining few spiritual doctors who insist on their own ideas are almost wandering on the edge of society between humans and aliens.
