"Yosuke Hayashi doesn't look like a ninja. He looks young, smartly dressed and smiles a lot, and seems singularly unlikely to flip out and kill everyone in the room at the drop of a hat. Of course, ninjas are noted as masters of stealth, so we should be on our guard. Appearances can be deceptive.
That said, we suspect that real ninjas (with apologies to Masaaki Hatsumi) probably wouldn't announce themselves as being from Team Ninja. It seems a little, well, obvious."
