Momiji

Originating from the Ninja Gaiden series, she's part of the Hayabusa clan and the being Ryu's apprentice and the Dragon Shrine Maiden of the clan. She keeps the sacred Dragon's Eye in case Ryu even needs to use it on his sword. The clan sees her as a big sister type that they look up to. She's a kind lady, much like say Kasumi and Kokoro, and really loves to train herself to be the best she can be as a ninja, though she has a bad habit of over-training herself as a result. In any bout, she seems thankful and honored to be fighting her opponent and never really gloats or taunts them either. If she wins, she'll thank them for the match and wish them luck for later. She's also quite versatile when she needs to be, which is also much of the reason she joined the Venus festival in XVV since she saw it as another kind of training.
