Ten years after returning to her uncle's house, Sari felt an inexplicable sense of dread. She couldn't understand why, and could barely recall any memories of her uncle. Although her parents had always told her she used to be very close to him as a child, Sari had no recollection of that at all. Still troubled by this unease, one day she found herself alone with her uncle. Suddenly, he moved closer beside her and said wistfully, "I remember playing with you in this room too, Sari-chan." At those words, Sari grabbed her uncle's hand as he reached for the closet. Inside sat an old stuffed toy. The moment Sari laid eyes on it, her memories came rushing back. "That's right... I did something with this person...!!" From that moment on, Sari's life plunged into hell.
