Dad's hobby was recording the growth of his daughter, Himari, with a video camera. What began as an act of pure love and interest gradually twisted into something darker—soon he was filming her naked, and eventually progressed to engaging in physical relations with his own daughter. On nights when no one else was home, Dad eagerly anticipated touching Himari's pale, delicate skin. These sessions were no longer about documentation—they existed solely to satisfy his desires. For him, tracking Himari's development had become his only source of pleasure.
