Story :  Kaguya Kawasumi is a top-rate devil executioner... and a virgin sorely lacking in sexual experience.
After accepting a standard request to execute devils in a certain town, she finds... that the devils there have sexual urges! The devils, armed with all sorts of obscene powers, aim for Kaguya's body. While Kaguya has never lost any "normal" fights as a devil executioner, she's toyed with by the devils, confused by the sexual attacks she's never experienced before. Bound spread-eagle and violated by tentacles... Doused in aphrodisiac, made sensitive, made to cum, and sucked of her spiritual power... And assaulted on a train by a group of humans controlled by a devil... Kaguya can only writhe her virgin body as the perverted devils have their way with her!
