Blood Rose ( Diabolik Lovers )
Shina Komori, that's my name, and Yui's my sister. One day, our father sent us to mansion to live there. A mansion, where my whole world got twisted yet interesting. The Sakamaki brothers, who I thought were just rich people were actually vampires. It really didn't matter how dangerous they are, because my wish, my greatest wish, came true. What wish? A wish to meet vampires. We became their blood banks, but that's not the end of it. There's more going on than you thought.
