Anzu está curtindo tanto a vida de solteira que nem pensa em romance. Até que uma criatura mágica transforma a vida desta jovem em uma comédia romântica bem clichê.

Once upon a time, in a far, faraway place, there were two lands. The world was divided into an inner land and an outer land. People feared the outer land. Inhabited by eerie beings, the carriers of curse. One day on the border to the inner land inhabited by humans, one such being find a girl on heaps of abandoned dead bodies. The girl says her name is Shiva and shows affection to the "being" who found her, calling him "Teacher". This is a story of two people; one human, one inhuman, who linger in the hazy twilight that separates night from day.

Na Tóquio imperial, um grupo de autodenominados "Jaegers" caça em segredo os vampiros que procuram a Arca de Sirius. Entre eles está o jovem lobisomem Yuliy.
