Yui Komori, who is still being kept hostage by the Sakamaki brothers—pureblood vampires wanting her blood—experiences even more strange twists in her life during her stay at their home. Despite being troubled by ambiguous dreams, Yui quickly deciphers their meaning when she is involved in a vehicle accident, which leads to her encountering four new vampires: the Mukami brothers, Ruki, Azusa, Kou, and Yuuma, who capture the befuddled girl. Yui later awakens at the Mukami home, where the brothers disclose their plans for her: she is their "Eve," and her blood will find the "Adam" among them; together, they will be able to conquer the world. However, with the Sakamaki brothers on their tail, things may not go as easily as they had hoped.
