Some family curses run deeper than blood.
Kazuna Takashiro has lived an ordinary life apart from the family that abandoned him—until he begins experiencing an insatiable craving for blood. Reunited with his older sister Chizuna, he discovers that they share a hereditary illness that has haunted the Takashiro family for generations. As the siblings struggle against their condition and the isolation it brings, they are forced to confront painful truths about love, sacrifice, and the burden of their shared fate. Created by Kei Toume, Lament of the Lamb is a haunting psychological drama that uses vampiric imagery to explore grief, illness, and the complexities of family.
