Kizuato

Kashiwagi Kouichi moves into his cousin's home after his father's death. The house is shared with four female cousins—Chizuru, Azusa, Kaede, and Hatsune—who range in age from a young child to an adult. Their parents died years ago, and Kouichi's father had been their guardian. He adapts well to the household, though Kaede remains distant. Kouichi begins experiencing intense dreams in which he is a murderous creature. He dismisses them at first, but the dreams grow more disturbing, accompanied by a chilling voice. What unsettles him most is the possibility that these dreams may reflect actual events.
