Short Answer
Yazhi Swaruu identifies the black-eyed children as vampires. In a conversation about whether vampires are real, she states: "Another kind are black-eyed, like black-eyed children. Those are vampires. Don't let them in the house or anywhere, just stay away from them" (394). She adds that vampires "in the streets they can pass as black-eyed children, but I feel that is another variant" — suggesting that the black-eyed children phenomenon and vampires as described in folklore may overlap but are not necessarily identical.
This is the only direct treatment of black-eyed children in the corpus. No further detail is provided about their nature, origin, or mechanism — only the classification as vampiric and the strong warning to avoid them.
