Jasmine

Yui Komori, still held captive by the Sakamaki brothers—pureblood vampires after her blood—experiences yet more bizarre twists to her life following her stay at their household. Though haunted by enigmatic dreams, Yui soon deciphers their meaning when caught in a car crash, which subsequently leads to meeting four new vampires: the Mukami brothers, Ruki, Azusa, Kou, and Yuuma, who themselves capture the bewildered girl.

The heroine, Komori Yui, has always been an ordinary high school student - excluding the fact that as a child, strange, supernatural things happened to her. However, she has always been able to maintain a positive outlook on life.
