Demon Swordsman

In the Gray Wall Era, humans have been slaughtered by countless demons, and they can only survive by hiding under the tall city walls built in the Golden Era. God has not shown any favor, but the demons have traded to humans a technology that can kill themselves - the anti-demon swordsman is also called the Stigma Sister. Beautiful appearance, extraordinary skills, but lifespan is extremely short and easy to fall. See how Adrian leads this group of beautiful and miserable nuns to gain power, fight against the nobility, the Holy See, and even eliminate demons.
