When we were jung, we were taught the difference between a hero and a villain. Good and evil. But what if the only real difference is the person who tells the story? What if demons aren't evil? What if they could live with humans but chose the difficult way? Amd what happens when both human and demon collide into one, new, peace, stong creature? Who would that be? Would it change the world forever? Well, that was completely up to this so called onika. Aki Katsushika, a fusion of a demon and a human. What will change? Are demons really bad?
