When the cursed box is opened, the long-sealed resentment begins to cry out.
Exorcist Shion Kujo and her assistant Guest are approached by a client, Rin Asakura, with a desperate request. Ever since an old wooden box—a Kotorigako—was found in her home, her family members have suffered a string of mysterious accidents and deaths. Every victim left behind the same final words: "I can hear a child's voice." As the investigation proceeds, it becomes clear that the box contains human malice and obsession. But more terrifying than the curse itself are the humans who created it.
