Shinta is a student at an elite university in Tokyo, leading an ordinary and peaceful life. One day he meets Lilith, a beautiful girl from Romania who has just transferred to the school. This encounter changes Shinta's life, as he soon finds out that he is the last in a long line of vampire slayers; and Lilith is, in fact, a vampire--his eternal foe! In order for Lilith to live on, she must conceive a child with the slayer, and then kill them both and bathe in their blood. Faced with their inevitable destiny, what does the future hold?
