Miss Sadistic Night (Diabolik Lovers)

Artemis and Apolla were shocked to learn they were no longer going to be living at home. The news devastated them to the point they really only talked to each other. Things took a turn for the worse when they learned that their uncle, who had agreed to let them stay with him and his daughter, had gone away on a sudden overseas trip for his work. Now, the people looking after their cousin, only agreed to let one of the girls come and stay. It was was decided that Artemis would stay while Apolla went elsewhere. They talked very little, even to each other, after that.
What Artemis didn't count on, however, was the home to be filled with young, attractive teenage boys who all have dark pasts they want to stay that way.... and are also dying to sink their teeth into her.
