A Dark Rabbit Has Seven Lives centers on Taito, a boy who has been worn down by a recurring dream of a female vampire who claims she gave him her "poison." The voice follows him beyond sleep, surfacing while he is awake and making it hard to tell whether he is hallucinating, remembering, or being called back toward a hidden past.
After Taito survives an accident that should have killed him, the line between dream and reality shatters. The strange girl from his visions, the poison she left behind, and the half-forgotten promises surrounding them begin to reveal a truth far bigger than his everyday life. What first seemed like a private nightmare turns into a direct link to supernatural forces that are already closing in on him.
As ordinary routines give way to impossible events, Taito is dragged into a conflict shaped by memory, desire, and obligations that were never meant to stay buried. The series follows his struggle to understand the meaning of the dreams, survive the power tied to them, and face the reality that the world around him may have been waiting for his awakening all along.
