Onna must kill! Nikiita

O-Koto, who stole money from the shop where she was working at, became a woman who turned her back on the secular world because of that single moment of weakness. She was caught with the money by the shop owner, who, in exchange for overlooking her crime, took her virginity. Moreover, O-Koto is threatened by a mysterious mendicant monk who somehow knows about her crime, and has no way to resist his orders.
