In the 21st century, a family of vampires settled down on the grounds of Japan and lived a modest life whilst sucking on the blood of humans discreetly. However, the eldest daughter of the family, Karin Maaka, has an embarassing secret which cannot be revealed to anyone. Even though she is a vampire, she does not lack blood like her family members. Instead, she overproduces blood to the extent that she transfuses the excess into her victims, hence increasing their blood levels. Despite her troubling body characteristic, she attends school like any other high school student, that is until a new transfer student, Kenta Usui, enters her life.

    During the winter, Yuichi was hospitalized due to hepatitis. Randomly he would try to escape from the hospital but would get beat up by the nurse. One day, he happened to meet Rika, a girl of his age, in the next building. He was fascinated by her beauty, but she was very selfish girl. Although she led him by the nose, he began to be attracted by her. However, when Rika told him about her illness, he knew why she acted so selfish; she didn't have long to live. (Source: Animenfo.com)
