A fifteen year-old android boy who begins going to a Japanese school. He is naive, friendly and airheaded, but loves to eat rice. R has a tendency to turn his head around 180 degrees, take off his hands or feet, and get off a bicycle without stopping it. He is modelled after Dr. Narihara's son Akira, whom is barely aware of R's existence.
A self-proclaimed mad scientist who built R. His original plan was to utilize R in a plan for world domination, but scrapped the idea when Narihara realized it would be too much work. He throws R away, and only restarts interest in him when R enrolls himself in school. Narihara has a wife and a son named Akira, whom he based R's looks on. Narihara and his wife originally told the Camera Club that Akira died and was rebuilt in an Astro Boy-esque accident, only to have Akira walk by shortly after.
