If Team Ninja is smart, they'll expand on her character even more by tying her into Ninja Gaiden 4 as a remnant of the Tengu bloodthirsty for revenge against Hayabusa. Then when we least expect it, Bankotsubo is resurrected, and thus, hype for a villain in DOA6.
i dont see her doing anything of significance, she'll probably just be blowing skirts up with her wind and then Rachel and Momiji will show and be like "hey stop that"
