In his original world, he was an unremarkable middle-aged man ignored by the opposite sex. But after being transported to another world, his life becomes a journey of absolute carnal freedom.

It all started when he was falsely accused of groping by Mizuki, a high school girl with the body of a gravure idol. Suddenly, both were summoned to the realm of the gods. The Goddess Rakushel mediated their quarrel and bestowed upon them a holy mission: defeat the Demon King. They were sent down to a high-fantasy world reminiscent of medieval Europe.

However, there’s a catch. Defeating even the weakest monsters near the city is a struggle—and besides, the Demon King was actually slain 100 years ago!

Left to his own devices, the man visits a slave trader to form a party, where he meets the beautiful dog-eared girl, Fam. Soon after, he encounters Myra, a busty priestess at the church. As beautiful women appear one after another, the man—who was once too repressed to even speak to women—blossoms into a lecherous mastermind. The door to his dream harem life has finally swung wide open.
