From KH2, a lot of fans perceived Demyx as a coward because he runs away from situations and whatnot. In this game, Demyx states plainly that he's very, very lazy. It's to the point where other Organization members kinda pause when talking about him and say, "I'm pretty sure he does something around here, but I'm not sure what." :|; He also seems to have a lot of wild ideas, but not enough motivation to carry them out.

He's also scared of Larxene, but that's not surprising at all.
