(Y/N) is sent off to the Sakamaki household when Yui asks Ayato about having another female in the house. Little do they know (Y/N) has a past, an energetic best friend, and a very sarcastic older sister. They wont let (Y/N) leave them behind. What happens next? This story takes place after the whole Cordelia ordeal, but Yui was turned into a vampire. Plus, this is before the Mukamis. Disclaimer: Diabolik Lovers is not mine but the plot/events and some of the characters are.
