Diabolik Lovers (The Assassin's Attack)

"---Komori Yui. These are the girls that went into the Haunted Mansion. Most of them disappeared afterwards. Most likely, they were killed. I want the two of you to investigate the Mansion. Kill the owner if he/she's guilty."

"Yes sir."
~~~~~

Two sixteen years old girls, Yuisaki Riena and Matsuoka Sakura, code name Chain and Blood respectively, are Type S assassins (Type S assassins are assassins that are in charge of supernatural cases). They were ordered to investigate the case of the Haunt Mansion.

But their fates changed as soon as they entered the Mansion and met the six handsome vampires and the only female vampire, Komori Yui.

Will they be able to accomplish their mission or accidentally fall in love with them?
