Oni Chichi 2: Revenge

The Makino sisters—Natsume, Akira, and Fuyu—are preparing for their school’s summer training camp at the beach. When their faculty advisor falls ill, leaving them in desperate need of a chaperone, the sisters decide to bring their father, Kenichi, along for the trip.

However, what the sisters see as a practical solution, Kenichi views as a golden opportunity. Driven by his festering, illicit desires, he has no intention of supervising a simple training camp. Amidst the secluded dunes and the sound of the crashing waves, Kenichi prepares to set his depraved plans into motion, turning a summer getaway into a harrowing ordeal of betrayal and obsession.
