In a land ruled by vile monsters, where death is common and life is cruel, one outcast endeavors to have it all. When misfortune drags the odd goblin Stryg from his forest home and into the ruthless city of Hollow Shade, he must try and adapt to a world that only sees him as a dimwit savage.Stryg finds himself embroiled in a school of magic, where an aristocrat's smile is filled with deceit and the simplest of remarks may lead to death threats. Yet nothing will stop him from aspiring to his beliefs of glory: power, honor, and food with salt.But as Stryg navigates through the muddled grey waters of the Ebon Realm, he will learn that some monsters lurk everywhere.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

The end of the world comes suddenly, and when most people turn into zombies, order and morality collapses completely. Our Protagonist is determined to stay alive.But he isn’t completely alone. He has a special pet; a Thousand-Legged Blood Centipede, a powerful creature that gets stronger with every battle.As he fights through the chaos, the centipede transforms into a Six-Winged Blood Centipede, then into an Eight-Winged Golden Centipede, and finally into a Ten-Winged Divine Centipede. Together, they become a powerful team that can change the future, even in the darkest times.The protagonist isn’t a hero; He kills zombies and keeps some in captivity.He saves people, protects people, and draws human blood to feed zombies.As the remaining people fight over what little they have, the idea of right and wrong is forgotten. He walks a thin line between being a hero and a villain, doing whatever it takes to survive.
