Kyuuketsuki (vampire) No Shouzou

I read on Mangafox.com and I found the name here on Yahoo, but I had a virus and now I can not find it. What I remember is that there was a school of vampire and a main character had black hair (Female), the other was something like a gun and his hair was white and there was a chick with dark hair and dark skin in the last chapter I think the guy with white hair was coughing up blood. If it rings bells all please tell me it's really good and I want to be red.
