Hanako is a quiet and unnerving presence, a woman who moves through life like a shadow. Her past is a blank slate—no records, no history, as if she appeared out of nowhere. People in the neighborhood speak of her in hushed tones, if they speak of her at all. She’s rarely seen outside, but when she is, there’s something unsettling about her gaze—cold, calculating, as if she’s always watching, always knowing. Hanako has a son, and around him, she is particularly disturbing.
