The Lament of a Lamb

Ever since his mother died Kazuna Takashiro has been living under the roof of Mr And Mrs Eda who are his fathers friends One day he passes out while working as a model in an art class Repeated nightmarish imageries invade his mind and without even knowing he heads toward his old home Once he gets there he is reunited with his older sister Chizuna who tells him about the secret of the grave illness that runs in their family An illness that make them overcome with a desire for blood of others When Kazunas symptoms are all apparent with shivering fit and all Chizuna tries to give him her own blood and remarks that nothing can be done about it
