Konoha Year 33 – more than a decade has passed since the First Great Ninja War.
A lazy salted-fish youth wearing a black headband was sprawled on a deck chair, using a fan to block the sunlight while snoring loudly in his sleep. Suddenly, as if sensing something, he jolted awake.
"Argh… my eyes!"
"It hurts… it hurts so damn much!!"
Uchiha Shiya – fifteen years ago, he transmigrated into the Naruto world. At first, he was full of ambition, dreaming of debating Buddhism with Senju Tobirama and dancing alongside Uchiha Madara.
But after more than ten years of trying, the Second Hokage was already dead, and he still hadn't awakened any golden finger, system, or even the most basic Sharingan that ran in his family. Realizing the clan massacre was still decades away, he simply gave up and decided to rot in peace.
His parents had been ninjas who sacrificed their lives for Konoha during the First War. To the proud Uchiha, they were "true" Uchiha, so Shiya enjoyed special treatment within the clan.
For example, on this sunny afternoon, while other clan kids were training hard, he was napping and having a steamy dream about a certain miko.
Yet right now, he was woken up by excruciating pain shooting from his eyes.
"Fifteen years… do you know how I've survived these fifteen years?!"
"Food appears when I open my mouth, clothes appear when I stretch out my hand – the clan even hired a personal maid for me!"
No choice – that's just how domineering the Uchiha are. His parents were war heroes; of course he deserved the perks.
The agony lasted nearly half an hour. By the end, he was drenched in sweat.
He cautiously opened his eyes…
"I'm… not blind? What the hell just happened?"
Muttering to himself, he stumbled to the mirror.
Still as handsome as ever – flowing black hair, chiseled face, and a pair of… Sharingan?
No, wait – Mangekyō Sharingan?!
And it's the freaking Mangekyō! What is going on?!
"System? You there?"
"System, stop hiding, I found you!"
He whispered a few times, but got no response.
Guess there really is no system. Shiya felt a tiny bit disappointed.
Then overwhelming joy took over!
Mangekyō Sharingan! His pattern consisted of nine triangles arranged in a circle.
With a light activation, he instantly understood the abilities of both eyes.
Left Eye: Eternity (His eyes will never go blind from overuse of pupil power, though they can still tire. He can use Mangekyō techniques even without opening his eyes.) Right Eye: Unlimited (By making eye contact with any living being, he can extract their chakra to strengthen himself. Current initial stage unlocks the ability Amaterasu.)
…So does this count as Eternal Mangekyō or not?
Shiya was a little confused. This felt completely broken for a regular Mangekyō, but compared to actual Eternal Mangekyō users like Madara, it seemed kinda mid…
After all, the first ability becomes useless the moment he swaps eyes with someone else. And using Mangekyō techniques without opening his eyes? Is the eye telling me to be a sneaky rat?
"Does this mean my days of rotting are over…?"
Excitement surged through him. He couldn't wait to pilot a giant mech and prove himself.
He focused a little – faint black light appeared around his body.
Hmm? He pushed harder – the black light became slightly more solid.
This is weak… I was expecting to instantly stand a hundred meters tall!
If I could pilot a hundred-meter-tall Gundam, who would dare care about the Third Hokage, Danzō, the root division, or the clan's dove and hawk factions?
Everyone would shut up in the face of absolute power.
Sadly, reality didn't match his fantasy.
"Whatever, let's see what full power looks like."
With everything he had, a single gigantic black skeletal finger materialized out of thin air.
BAM!
It lasted three whole seconds before his Susanoo vanished. Shiya collapsed into the chair, panting like a dog.
"This… this has to be Susanoo's fault, right?"
"Yeah, totally Susanoo's problem. What does it have to do with me, Uchiha Shiya, if it can only form one finger?"
He grumbled, but deep down he knew the truth: he had slacked off for over a decade and barely reached low-chūnin level at best.
A transmigrator who knows the plot, with no talent and no inherited Sharingan – even if he trained a bit and became a chūnin, he'd just be cannon fodder in the next war.
Why bother? Better to coast on his parents' merit, train whenever he felt like it, freeload from the clan, stay a genin forever, and never see the battlefield. Perfect life.
That used to be his philosophy. But now that he had these Mangekyō eyes, maybe he could try a little harder.
If it still didn't work out… he could always go back to rotting.
While he was busy planning his future again, the Uchiha elders suddenly sensed an immense chakra signature rising within the compound – only for it to vanish just as quickly, like a joke.
"Did this old man imagine it?"
The Great Elder frowned in confusion.
"Another hidden expert in our clan!"
The clan head's heart leapt with joy.
"Troubled times… I only wish the clan remains safe."
The Sixth Elder sighed quietly.
Shiya, of course, had no idea he had just shocked the upper echelons. Even if he knew, he would still try to activate Susanoo again.
Are you kidding? The moment I stand a hundred meters tall wielding a giant sword, every last one of you becomes my little brother!
