One Hero for the Monsters

A Ben 10/Rosario Vampire Crossover, I have racked my brain and done research and this is a story that will be updated whenever (Was that rude?) I hope you enjoy and R&R because it helps me so much. As always I do not own anything but the words on the screen. It's a Ben/Harem story. Multiple Girlfriends (Not the Witch {Yukari. I think that's her name}) Ultimate Forms (Yes/No)
