Thirteen years ago, a terrible monster called the Poison Queen attacked the Jade Kingdom. A brave party of adventurers defeated her, but in the process one of them was stricken with a curse. In order to survive, she had to pass it down to her own son. Scorned as a cursed child since birth, Caim Halsberg is hated by everyone except his late mother and Tea, a maid working for his family. While his father and twin sister reside in their mansion, Caim is forced to live alone in a forest hut. But everything changes when a certain doctor helps him to overcome the curse and claim its power. Having now become the Poison King, Caim goes on a journey to achieve his one wish—but he never imagined that his poison would have quite the peculiar effect on the beauties he meets!
After fusing with the Poison Queen and awakening as the Poison King, Caim has left the Jade Kingdom and headed for the Garnet Empire—accompanied by the three bewitching beauties who have become his lovers. However, just when he’s beginning to enjoy his first leisurely voyage on a ship, the liner is attacked by sky pirates! And even after they finally reach the empire, trouble keeps coming—first assassins and then the kidnapping of Millicia and Lenka. Just who is Millicia, and why was she abducted? The time has finally come to uncover the noble lady’s mysterious identity! And of course, the members of Caim’s harem keep coming at him for even more erotic situations all the while!
Now aware of Millicia’s circumstances, Caim and his companions head toward the capital of the Garnet Empire. Or at least, that was their objective—until they find their way blocked by a landslide and are forced to stay in the post town of Jarro. After picking up work as adventurers, they eventually make the drastic decision to head into the monster-infested forest of the lycaons, enlisting the help of a black rabbit beastfolk girl to guide them. At first, everything goes smoothly—so smoothly, in fact, that Caim is able to enjoy some nighttime fun. However, when they reach the inner part of the forest, they encounter an unexpectedly powerful foe!
