His malevolent actions draw the attention of an ancient evil, an entity wrapped in darkness and legend. This being sees in Grayson the potential to carry on its legacy.As the ancient evil begins to mold Grayson for a future drenched in darkness, he finds himself drawn deeper into a web of manipulation and control. Questioning whether he has the strength to defy the fate that has been thrust upon him.Theós, an ancient deity whose origins are lost to time, rules with an iron grip, instilling fear and absolute control over those who dare challenge him.“If it is not within Theós' plan, it cannot be done!”

A medical student died because of negligence of the authorities. Later, he is granted a second chance in life with some boons. But being an Otaku and Naruto fan, he chooses to live in the chaotic world of Naruto.

The story will follow canon for the initial part with a new plot. Major changes will reflect in the later part as our MC grows up. The story has strong AU elements and the power scaling is ramped up to explore various foreign elements in Naruto. Everything in its entirety will be a part of the Naruto series with details and speculations of my own.

This story is my original creation, and I post it on Scribble hub and Webnovel. You might find a few initial chapters on Royal Road.

Note:- The starting 40 chapters or so have poor grammar and various mistakes since I was a new writer back then and lacked experience. But I am working on editing them.

Warning:-I don't own Naruto or any related stuff except my MC and Original characters and jutsus. (Yep, there are lots and lots of original jutsus in the story.)

Kai’s life was small—coffee-stained mornings, cracked recipes, and a system in his head that tweaked toasters and dough like it was nothing. Then the sky shattered. Aliens—Skraiths, jagged and brutal—invaded, tearing his city apart with green-glowing weapons and relentless claws. Superhumans rose to fight back, fire and lightning blazing through the chaos, but Kai’s world crumbled with them.Hiding in his apartment, Kai stumbles on blood—human and alien, smeared on his wall after a superhuman battle. His system, once just a tinker’s tool, awakens, offering him a choice: mimic their powers, temporary and wild, through the blood itself. Desperate, he takes it—stealing pyrokinesis, then electrokinesis, then kinetic energy, each power burning through him, fading fast. But it’s not enough. Armed with a humming Skraith weapon and a body tougher from alien blood, Kai joins a ragtag crew of enhanced fighters—Liv, Rylan, Jace, and Tucker—scraping to survive in a warzone where every shadow hides death.As Skraiths swarm and the city burns, Kai’s system pushes him deeper, analyzing, integrating, crafting minor enhancements—durability, strength, sparks of power that could make him a target or a savior. Government factions, rogue scientists, and the aliens themselves start sniffing around, drawn to his strange tech and blood-stolen abilities. By the time Kai crafts his first super-powered enhancement—an artificial strength boost—he’s no longer just a tinkerer. He’s on the edge of something bigger, something dangerous, where blood and sparks could forge a hero—or break him entirely.In a world unraveling, Kai’s fight for survival becomes a desperate race to master his system, outrun the Skraiths, and confront the truth: the power he’s chasing might destroy him—or remake the world.
