He wouldn't know anything if he was a person of the land. Even if he was a faker and could somehow keep the act up, you'd think the others had noticed, no matter if they are still kids. That's why I rejected the idea. Well, I suppose there is a theoretical possibility for it, but I'd consider it a weakness in this otherwise solid enough story. Maybe it would be a little more plausible if he had spent a long time indeed in Akiba listening to the incomprehensible (to an NPC) prattle of the players, so that he could superficially act like one and offhandedly mention stuff from RL even though he had no idea what he's talking about. But that would make him a genius (as a conman), not an idiot like he is otherwise.
