As the new dark goddess, Kazuma continued to enjoy his authority over the other girls. But despite having a wild range of girls to choose from, Kazume only had a handfull of favorites. And among them, Eris was at the very top. Kazuma shared everything with the goddess of fortune, including a good portion of his new powers. This not only allowed Eris to become much stronger than the rest of the corrupted girls, it also granted him greater control over Eris's minds, causing Eris to do anything he wanted without any rejections.
Little did he knew that the dark goddess's will inside of him already had another plans. This was all to prepare Eris to become its next vessel, one that is even more powerful than Kazuma himself.
