In Japan, Kiriko Hikari Mitsushima Imazato and her younger half-brother Daigo Takeru Shibuya Imazato live with their father Kohei Teruyuki Kagawa Imazato, a book illustrator whose latest project consumes his attention. Daigo’s behavior takes a troubling turn when he inexplicably beats a rabbit to death outside his school, and soon after he stops attending classes. Kiriko watches the change with growing concern, while Kohei remains absorbed in his work and the demands of his craft.
Kiriko’s worry deepens as Daigo’s conduct becomes more unpredictable, and she senses something is seriously off. Their father’s distraction with his pop-up book about The Little Mermaid only widens the distance between them, leaving Kiriko to shoulder the burden of understanding what’s happening to her brother. The family’s quiet equilibrium starts to fracture, and a sense of unease settles over their home.
To seek an escape or perhaps a clue, Kiriko and Daigo are drawn to a 3-D horror experience: The Shock Labyrinth, a film where a rabbit doll appears to float from the screen and into Daigo’s hands. The sight unsettles the siblings, and when Daigo takes the doll home, a surreal and menacing chain of events begins to unfold. That night, a large version of the doll pulls him through a cupboard into a fairground, a moment that blurs the line between cinema’s illusion and a waking nightmare.
The following night, the rabbit’s influence intensifies as Daigo is pulled through the mattress of his own bed. Kiriko, driven by fear and a sense of responsibility, follows him to uncover what is really happening. The two find themselves venturing to an abandoned hospital, a place that seems to hold the answers their family cannot provide. The tension between what is real and what haunts them grows more tangled as their investigation deepens.
Back home, Kiriko confronts her father with a chilling revelation: “Kyoko is coming. I saw her.” The memory of Kyoko—the woman Kohei brought home years earlier as his pregnant second wife—surfaces with startling clarity. Kiriko recalls a young version of herself attacking Kyoko, a moment that has lingered in their family history. Now the siblings come to believe that Kyoko has returned in a rabbit costume, and they become certain that the eerie doll must be stopped. The fear becomes a shared purpose as they resolve to destroy the doll and the threat it represents, wrestling with memory, guilt, and the possibility of a revenant haunting their lives.
> Kyoko is coming. I saw her.
As the story unfolds, the atmosphere stays taut and ominous, weaving together the trauma of a fractured family, the lure of a cursed object, and the eerie possibility that the past can return in the most unsettling forms. Kiriko and Daigo’s bond is put to the test as they navigate a web of superstition, guilt, and fear, all while a mysterious doll and a haunting rabbit image loom over every choice they make. The film maintains a restrained, disturbing tone that invites viewers to question what they are witnessing and who—or what—is truly in control.
