A Monster Hunter in a Highschool For Monsters (Rosario+Vampire)

I hunt monsters for the Government. That's what I was raised for, and it's what I died for. It's all I'd ever known, other than a few on and off romances I'd had with other hunters, and a few life-long friends I'd made by hunting and surviving with them. I was never religious. I felt if there was a God or a Devil, they might as well be the same person. So imagine my surprise when I wake up on a bus, in a younger version of my body but the body already had an identity. Imagine my further surprise when I found out that wherever I was going, was in fact, a school. A school full of monsters. How did I find this out? A weird pink-haired girl sucked some of my blood and called it the most delicious thing she'd ever tasted. (A warning from the Author: Sappy romance will be very prevalent in this story, so get out now if you don't wanna see it. Don't expect complex romance but don't expect anything too simple. There will be a few obstacles but not anything too major.)
