You're a human (obviously), however you're a human in a world ruled by demons, ranging from the Japanese Oni to the Greek Gorgons, no one remembers where they came from, and this story does not attempt to find out, no. This is a story about how you met a mischievous Succubus and how your stories intertwine within this demonic world. Do you succumb to the nature of the Succubus? Or perhaps... do you try to change the very nature of this demon? Why not find out?
