Mikiya's three-year blindness to what Shiki actually is becomes the entire point: love that doesn't require understanding, only acceptance. The film refuses to explain her murders until you've already fallen for her too, which means you're complicit in the same denial he is. By the time the violence arrives on screen, ufotable's backgrounds have already made you feel the weight of a girl trying to exist in a world that can't contain her.
Mikiya meets Shiki on a quiet night in March 1995, captivated by something ineffable in her gaze. When they cross paths again at his high school entrance ceremony in April, he's drawn to reconnect with her. But Shiki carries secrets that run deeper than attraction. A string of murders grips the city, each victim seemingly random, each crime a puzzle with no visible pattern or motive. The deaths pile up without explanation, leaving investigators baffled and the public unsettled. Mikiya finds himself entangled with Shiki as the killings continue, unaware that the girl he's falling for holds a connection to the violence far more intimate than coincidence. Their relationship becomes a slow-burning mystery where tenderness masks something far darker. What Mikiya doesn't realize until years later will shatter everything he thought he understood about the person beside him. This is noir psychology wrapped in supernatural dread: a romance that turns into something stranger and more unsettling with each passing revelation.
