A fairy who takes over a girl’s body… The treasure hunter Barrett, while drowning in carnal male pleasure, has his wish to have his body turned into that of a woman granted by the girl. Barrett, with his new body, becomes the girl’s Chevalier: a fighting maid.
In response to the scantily clad shrine maiden Nonoa’s sudden disappearance, Yamato and Sera desperately search for her. They pilot an unconventional search and rescue aircraft, the dongcopter, that uses Yamato’s spinning phallus in lieu of a propeller to provide lift and thrust. However, Yamato gets too aroused mid-flight, his penis further engorges, and it shreds the aircraft’s fuselage sending them plummeting towards the mountains below. They survive. Leaving the unsalvageable wreckage of the dongcopter behind them, they continue the search for Filika’s hideout on foot. Even in such a dire situation, Yamato’s sexual desire is ever-present. He convinces the naïve Sera that the human penis is actually a tail and then seeks “medical treatment” from her for his “swollen tail”. He entreats her to take him inside her to reduce the swelling. Sera hesitates for a moment, only to offer up her ass. “You can use this hole if you’d like,” she says. Yamato, so thoroughly aroused, penetrates her forcefully and without hesitation. She feels uncomfortable at first, but her cries gradually become tainted with pleasure. The moans of an angel’s fall from grace echo in the mountains. Filika and her captive, Nonoa, over whom Filika has complete control, appear before them. Filika orders Nonoa, who is in devil cosplay and who has Filika’s egg cells inside her from an earlier ritual, to milk Yamato for his semen. If Yamato gets her pregnant, she will bear Filika’s demon child! Nonoa slowly draws near. Wishing to save Nonoa from Filika’s control but also at the mercy of his own desires, Yamato springs into action!
Takeru, Mikoto and Sui are back and this time they are under the full control of a dark yoma specialist. As much as they struggle to escape they are forced to be a breeding ground for insect like demons. Takeru has given in fully to the yoma and her lust for her sister Mikoto is clouding her mind. Can they be saved?
When half-naked shrine maiden Nonoa suddenly disappears, her childhood friend Yamato and an angel, Sera are thrown into a panic! Sera finds it strange that Filika, a devil, disappeared at exactly the same time. Equipping an angel’s halo and Nonoa’s panties, Yamato unlocks his hidden potential, and his penis grows in size. He spins it rapidly to achieve propelled flight, and he and Sera take off in hot pursuit of the naturally flight-capable Filika. Meanwhile, Filika abducts Monika and returns to her hidden base of operations. She then uses her sex slaves, once men but now creatures only of lust, to begin a questionable ritual. Monika milks her slaves for their semen. She repeatedly engages them in rough, nigh-beast-like sex and naturally succumbs to the overwhelming pleasure. She is repeatedly creampied, and as a result her abdomen swells from the sheer volume of semen inside her. Meanwhile, completely oblivious, Nonoa is taking a shower. Belly bulging, Filika sneaks up on Nonoa and uses her to complete the ritual.
