Lilith's Cord
Lilith's Code / Код Лилит / リリス・コード / 릴리스 코드

Most humans are considered descendants of Adam and Eve, but a small number belong to a different lineage: they are children of Lilith, who is said to have been Adam’s first Eve. Though they look just like the descendants of Eve, Lilith’s children live among ordinary people, scattered somewhere in the world. Their presence sets them apart from the familiar account of humanity’s origins, even as they remain difficult to distinguish from everyone else.
