The Mysterious Ninja in Dirge of Cerberus Final Fantasy VII

We all know that its a Mysterious Ninja that is supose to be in Dirge of Cerberus but the question is, who could the ninja be? Well to cear up some confusion, heres a pic of the ninja. Do you notice that the ninja has the same weapon as Yuffie? Lets not forget that Yuffie is a ninja aswell. I've been thinking about this and I've come to the conclusion that this Ninja could be a relative of Yuffie. Who ever this mysterious ninja is, I wonder if she or he will play a big role in FF VII Dirge of Cerberus.

It's Yuffie. Sorry to spoil everything. The only characters that is a real secret is G who is played by Gackt. You'll also learn about Lucrecia studies related to G Substance. If you have kept your eye on Crisis Core, you notice that G is a SOLDIER in a image with SOLDIER Sephiroth, SOLDIER Zack, SOLDIER Angeal, Tseng, and MP Cloud. Sephiroth also makes a reference to the G Project which Zack questions in a screenshot. G is only seen once in DoC as this mysterious person.NeoGen85

Thanks for clearing that up.

My god, it's obvious it's Yuffie... Has no one seen footage of DoC with her yet?! If you have, the lips match up perfectly!

Prove me wrong if you can.
