Of course he knows that Ninja's did exist but what she asked was when i saw one last time. We also know that Samurai's existed we aren't morons. Don't come in here and act like and idiot.

As for those books on ninjas having control over natural powers. I will believe it when i see it. Its the same as Aliens, Ghosts and other super natural things. People claim to have seen all kinds of shit but no one knows for sure, those books may just be bullshit.
