Vampires capture Yuu and Mika (as well as the rest of the children at the orphanage where they lived) when a virus kills everyone over the age of thirteen. The Vampires bring them, and almost all who survived the virus, to their underground cities to be their “cattle”. After four years of captivity they make a plan to escape.
