Kunoichi Gakuen Ninpouchou 4

In the moonlit shadows of Iga, Yatsurugi Shinobu and Mashiba Aya share a passionate, heated night, only for Aya to fall victim to a parasitic lust that consumes her. Now, Kage Lena faces the same fate, her body burning with insatiable hunger. To save her, Shinobu must infiltrate the Koga Institute, where the only antidote lies hidden—racing against time before Lena surrenders entirely to the all-consuming pleasure and darkness of the parasite’s grip.
