It's possible that they'll do a "The Oni Masks cannot be destroyed or the dead Oni will come and kill us all!" Kind of Thing and the Ninja have to find the Mask of Vengence, Which it would turn out Harumi has. But then she would have loved and gotten away. I doubt they would actually do that though.
