9番の男

A fidgety, nervous man from the start, he knows more than he's letting on. The 9th Man is the only one who does not get to pick what his codename is so the rest of the players refer to him as the 9th Man during the Nonary Game.

His real name is Teruaki Kubota (窪田 輝昭). Not much about Kubota's early life is known, other than that he was a member of Free the Soul.

During the First Nonary Game, Kubota was one of the four executives of Cradle Pharmaceutical and was Cradle Pharmaceutical R&D Supervisor. He was part of the creation of the Nonary Project, also known as the First Nonary Game. The First Nonary Game's purpose was to see whether humans could telepathically connect through the morphogenetic field. He created the necessary technology required for the Nonary Game. 

As the supervisor of the R&D department, he was the creator of the RED and DEAD devices used to open the numbered doors and conducted the actual experiments to test them. He also created the numbered bracelets worn by players in the First Nonary Game, since the bracelets were needed to open the numbered doors because of the concept of digital roots involved. /
