Well, Heres one of my Twilight OC's, Yami Momo (I know, weird name right? o.0)

Shes 16 years old, and the story takes place in modern Tokyo, where she meets 3 vampires that have been going to school for only a month before her. Of course Yami is more "informed" than other humans, so she knows just what shes dealing with, a group of hyperactive vampires!
