Harmonia

In the distant future, the Earth has been ravaged by an immense war, leaving the human population dwindling. In this ruined world, a humanoid robot boy, designated Phiroid, awakens in a disused facility. Prior to the war, Phiroids were the purest form of human scientific achievement, imbued with all five senses and emotive functionality. Designed as partners for humans, they promised to make life better for all humanity. When this boy-type Phiroid awakens, however, he quickly realizes that he is missing his emotive functions. Harboring an innate need for human contact, and to regain his missing emotions, he sets out into the devastated earth. Having walked for countless days, he eventually loses consciousness, only to be saved by a lone girl. Thinking that he is human, the girl takes good care of him. As this Phiroid boy lives alongside this girl, little by little, he comes to learn about emotions.
