Nariyuki "Dr. Narihara" Narihara

About

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. (souse: wikipedia)
