Death is a Kiss

There's a new girl in town called Dahlia, who attends an elite high school. She's hated by the other girls. They think she's stuck up, but they also suspect her of committing the murders in the neighborhood.

Dahlia is a vampire, with one eye that turns green when her vampire nature awakens. She came to this area to search for her lost love, who also is the one who made her into a vampire. She attends the same high school as a young man who resembles her lost love. Maybe it's him. She's going to find out by awakening the boy's memory of his past.
