On December 12, 2040, twelve black dragons called “Star-Corroding Annihilators: Naxaroth” appeared on Blue Star without warning. Their bodies blotted out the sky, their scales were as hard as if forged by the gods, and every breath they exhaled brought destruction. At first, some thought they were witnessing a divine miracle, only to be corroded into skeletons by green poison in the blink of an eye.
Their roars could mutate, melt, and rot the flesh of every living thing within five kilometers. The land they crawled across spread corrosive fluid and fungi, giving rise to monsters called “Omega Mutants: Type Zero.” They had skin like copper and bones like iron, the form of dragons, and even wings that carried them into the sky.
Humanity's missiles, guns, and cannons were toys before them. The world crumbled in no time, and lives were crushed like an ant colony beneath someone's hand.
He fought with his last breath and finally killed one of the “Naxaroth.” But when he turned around, Blue Star had already rotted away, and everyone he knew was gone. His little sister, his beloved... none of them were left.
If there was no point in living alone, then he might as well give everything he had and strike one more time!
“Ha... if the heavens want to destroy us... then... let everything be destroyed!” “One-Sword Style: Death Lion's Song!”
That slash was modeled on Zoro's technique from One Piece, but infused with all his own Haki and resolve. It was ten times stronger than Zoro's slash had been back then.
He had neither a three-sword style nor thirteen famous blades. He didn't know if this strike could take down another enemy, or buy the survivors a glimmer of hope. He fell into the corrosive fluid, his body rapidly dissolving...
But when he opened his eyes again, he had somehow returned to December 11, 2025, before the apocalypse.
