This is a story of a universe. One that had always believed in and had adhered to the notion of  neutrality,that's why unlike other universes it never interfered in the growth of it's beings, and for a time this had allowed it to achieve success. That is until it realised it's luck had run out, remaining neutral was no longer enough. So in a desperate gamble it formulated a plan, one no sane universe could ever think of. . It waited for thousands of years until it was at the peak of multiverse level and then initiated its plan. It had managed steal the genetic information of both the Abyss's  and Heavenly plane's dominant species, Although this had cost it nearly everything it was still a rather impressive feat, as it had stolen from TWO OMNIVERSES. Using this it manage to create demons of sin and angels that (unlike other universes which contained 0.000000000001%of the original bloodline from the Abyss and Heavenly plane) contained 0.1% bloodline purity. A world Kyle knew very after all it was the last thing he read about before the lights went off. 'Forsaken hero' a book about a regressed hero and his journey through the world of Abrium. You could imagine Kyle's shock when he suddenly reincarnated in that very same novel as Kyle Grambell. The heir of house Grambell, a family that's basically like the royal family of the demon continent, the very same Kyle that got killed by the protagonist in the later half of the book. The very same one whose older sister, Synthea Grambell, is the demon monarch. Now as a demon of pride and as a reincanator it would be a disgrace if he was satisfied with merely surviving. Follow the journey of a Kyle, a man more demonic and prideful than any demon, as he spreads chaos, death, suffering and uncovers the true nature of this world (or universe) including his role in it.
