Yui's Little Sister (Diabolik Lovers Fanfic)

Yui and her little sister Mao have been told by their father to live with his distant relative the Sakamaki's.

If you watched Diabolik Lovers you understand how it goes for Yui but how will it go for Mao.

Will the Vampires get addicted to her blood? What will they think of her? Will they find out her secrets? Will they understand why she is the way she is? Will they get suspicious that she is hiding something?
