Kunoichi Gakuen Ninpouchou 5

As darkness descends, Yatsurugi Shinobi’s friend Mashiba Aya falls victim to a parasitic infection that awakens insatiable lust, turning her into a slave to desire. The same fate threatens Kage Lena, driving the ninja women into peril to save her. With the cure hidden deep in the Koga Institute’s labs, their mission becomes a desperate race against time—and the overwhelming urges consuming their bodies—fueled by passion and survival. Their steamy encounters only heighten the danger at hand.
