In response to the sudden disappearance of the meager priestess Nonoa Yamato and sulfur desperately looking for her. They will pilot an unconventional search and rescue plane, Dongcopter, which uses the rotating phallus Yamato instead of a propeller to provide lifting force and traction. However, Yamato is too excited in the middle of the flight, his penis swells even more, and he breaks the fuselage of the aircraft, sending them towards the mountains below. They survive. Leaving behind them not to restore the wreckage of the Dongkopter, they continue to search for the refuge of Filika on foot. Even in such a terrible situation, Yamato"s sexual desire does not leave him. He convinces the naive sulfur that the human penis is actually a tail, and then turns to it for the “treatment” of his “swollen tail”. He begs her to take him inside himself to reduce the tumor. The sulfur fluctuates for a moment, only to offer her ass. “You can use this hole if you want,” she says. Yamato, so excited, penetrates into it strongly and without hesitation. At first she feels uncomfortable, but gradually her screams become painted by pleasure. The groans of the fall of the Angel are surrendered in the mountains. Filik and her captive Nonoa appear in front of them, over which Filika has full control. Filika orders Nonoa, who is in the cosplay of the devil and in which there are an eggs of Filika from an earlier ritual inside, to milk Yamato to obtain his sperm. If Yamato makes her pregnant, she will give birth to a child-derman of Filika! Nonoa is slowly approaching. Wanting to save Nonoa from the control of Filika, but also in the power of his own desires, Yamato rushes into battle!
