Seven is, truly a shocking revelation, the seventh participant in the Nonary Game. You'd probably never guess what the motivation behind his codename is. Seven is a tall, muscular man with even less recollection of how he ended up on that ship than everyone else. Nevertheless, he seems to have a keen eye for things within rooms that others might overlook. (NOTE: He's prone to making questionable and offensive comments, mainly directed at a female character in the cast, so this role may not be for everybody.)

For voice reference, the Zero Escape: The Nonary Games trailer could serve (since I couldn't find any isolated voice lines, I apologize) as inspiration, although unique takes are very much welcome!
