Kiyotaka Ayanokouji, the fourth generation demon and perfect human, was known by many names, admired by some and despised by others. His abilities were undeniable, but his very existence was feared.

This new life was his chance to finally experience the independence he craved. But the challenges he faced were even greater than before. In a world where power is everything and deities walk among mortals, Kiyotaka must overcome each obstacle that comes his way. As he navigates this dangerous world, he will discover that his incredible abilities are both a blessing and a curse.

One day, without warning, a member of the Ministry of Defense and a mysterious creature with a grotesque appearance arrived before Class 3-E of Kunugigaoka Junior High School, a class made up of students with poor academic records and bad behavior at the prestigious school. The dangerous creature, capable of flying through the sky at Mach 20 and having already destroyed seventy percent of the moon, leaving it permanently in a crescent shape, declared that "if I am not killed by next March, I will destroy the Earth," and requested to become the homeroom teacher of Kunugigaoka Junior High School Class 3-E. In order to assassinate the creature, the government turns to the White Room's greatest masterpiece, Ayanokōji Kiyotaka, and asks him to carry out the assassination. Will Ayanokōji be able to take down the target?

Esta é uma fanfic em que Ayanokoji Kiyotaka renasci em uma novel que tinha lido por pouco tempo após ser morto pelo seu pai. Agora o que o nosso protagonista favorito calculista e manipulador fará em um mundo desconhecido?

In the neon-drenched streets of Kuoh, where the shadows of angels and demons dance in a perpetual, silent war, walks a young man with eyes as vacant as a forgotten grave. Kiyotaka Ayanokoji never asked for a second life, let alone to become the vessel for Austin Griffin-the nine-headed Heavenly Calamity whose very breath is the countdown to the end of time. ​For Kiyotaka, the world has always been a sterile chessboard, and people were merely pieces to be moved, sacrificed, or discarded. But in this new reality, he is no longer a pawn of the White Room; he is the third player at a table meant for only two. ​Refusing to be bound by the chains of the Devil's Evil Piece system, Kiyotaka begins to weave his own web. Using the resonance of the Calamity God, he summons those lost between dimensions-the "unworthy" who are, in truth, the only ones worthy of standing by his side. From Artoria, the fallen king seeking a new oath, to Reina and Luna, celestial entities bound to him by blood and dragon-fire, his circle grows into a force that defies the logic of the Three Factions. ​Yet, as the seals on the nine-headed Chimera begin to crack, threatening to erase existence itself, Kiyotaka encounters a variable he cannot calculate: Humanity. ​As the ancient conspiracy of Qlippoth stirs and the beast Trihexa awakens to herald the apocalypse, the cold walls around Kiyotaka's heart start to crumble. Through the playful whispers of Kuroka, the divine grace of Sytry, and the unwavering loyalty of his gathered harem, the "Masterpiece" is forced to confront a terrifying glitch in his programming. ​This is not just a chronicle of absolute destruction. It is the story of a boy who was raised to be a machine, struggling to decide if he will remain a God of Extinction who erases the world, or become a man who finally has something worth saving.

This is a world that is secretly governed by Devils, Angels, and Gods. A game between factions where beings high and mighty sit on their throne and rear humans as cattle. A race born with no magical talent, no supernatural gift and no fate lives on in ignorance as they are led into a world where slavery is a beautiful illusion. I, too, lived in ignorance until an unexpected incident occurred during middle-school. And that is the day my world overturned and I was forced to question myself- In this world, where even a perfect human was worthless, what was the significance my own existence? ...

There's much more I want to say but they'll be spoilers. Please enjoy the story.
