Recognized for her pure heart and devout faith, Sister Misha is entrusted with a church whose former administrator has gone missing. However, the church is located in a remote frontier town on the frontlines of the battle against monsters. Despite being subjected to the lustful gazes of the town’s rough and unruly men every day, Misha remains determined to fulfill her sacred duty. Then, one day, a entity claiming to be the Succubus Goddess suddenly appears before her and reveals a shocking truth… “It won’t be long before you turn into a succubus, just like your ancestor. However, if you gather more of the lust directed toward you, I’ll make sure you can stay human.”
