Luka, a hero who saved the world from the evil clutches of Goddess Ilias, continues his journey with Alice, to see the world where humans and monsters peacefully coexist. One day, a village is under attack by Succubi, and Luka and Alice arrive to fight them off. A mysterious succubus oversees the battle and transports the pair into an empty dimensional space dubbed the "world of temptation." Alice is suddenly distracted by the appearance of parfaits, which confuses Luka as he does not see them, and Alice mysteriously vanishes from view. Luka is then swarmed by succubi, but finds himself weakened in the dimensional space, allowing the succubi to RAPE him without resistance. Luka passes out and wakes to find Erubetie looking over him, only for her to immediately rape him. Luka passes out again, where Alma Elma approaches and rapes him as well. Despite the overwhelming pleasure that leaves him on the brink of death, Luka manages to cling to his sanity, acknowledging that Erubetie and Alma Elma aren't behaving normally and that someone else must be pulling the strings. The mysterious overseeing succubus realizes Luka's heart can't be won over easily, as expected of the hero who defeated Goddess Ilias, and continues to toy Luka within the world of temptation until he breaks.
