When a fiery comet split the sky, the world burned—and Akino’s life shattered.
Seventeen-year-old convenience store worker Akino never imagined he'd lose everything in a single night. But when the sky rained fire and monsters followed, he watched helplessly as his mother was murdered by a being not of this world.
Now infused with a mysterious black substance from the comet, Akino is caught in a deadly new reality—one where strength decides who survives.
But Akino won’t run. He’ll fight. He’ll burn. And he’ll make the Demon Lord pay.
Earth has become a battlefield. And Akino has just joined the war.
