Lament of the Lamb

"Chizuna has an unhealthy longing for her late father, and her fragile emotional state only serves to make her thirst for blood even stronger. Her brother Kazuna hopes to fulfill her needs by offering himself as nourishment. After all, he does remind Chizuna of Father, but her cravings might now be too extreme. Kazuna's growing anxiety about their condition causes him to push Yaegashi away and isolate himself from the world. While being vampires has caused the siblings much pain and trauma, it has also brought them closer."--Cover, P. [4].
