ریوی نینومییا

A young programmer living on the top floor in the high-class mansion-apartment building Glorious Tower Toyosu in Tokyo's Koto ward. His trump card is his superb intellect; he is trilingual, being able to speak English, Japanese, and Chinese. After educating himself using educational websites and learning how to write code from hackers around the world, he developed the social networking services "GALAX" and "President X." Rui believes that the current Japan is extremely boring, and does many things in order to speed up and update the world.

[Spoiler: It later on revealed that he's just Katze Berg's pawn to use their "GALAX" to create bigger chaos.]
