Chapter 1: Chapter 1 : Tsunade
"Hmm? This memory…hiss~"
Uchiha Shin woke up in a daze, rubbing his swollen temples as a flood of memories surged through his mind.
"I didn't expect this… I actually transmigrated into the world of Naruto? My past life's memories… they feel like a dream."
He furrowed his brows, his fingers tracing the fabric of his sheets. A thought struck him suddenly.
"But where's my cheat ability? My System? Where's the 'ding ding ding' notification?"
Muttering to himself, he sat up and pressed down on something soft, his small hand sinking into an unexpectedly plush sensation.
"Mm… stop moving, kid. Ugh, I swear, I can't handle drinking anymore. And you puked all over me last night…"
A lazy, drowsy voice murmured beside him. Before he could react, a fair, delicate hand draped over his stomach.
Feeling the warmth and softness, Uchiha Shin stiffened, his gaze slowly moving toward the figure lying next to him. Tsunade, the future Sannin, was fast asleep beside him. Her smooth, ivory skin, cascading golden hair, and youthful, delicate features made her look utterly ethereal. Her slightly disheveled nightwear did little to hide the allure of her figure, and her slow, steady breaths carried the faint scent of alcohol.
A surge of adrenaline shot through him, snapping him into full wakefulness.
Taking a deep breath, he caught the lingering traces of alcohol on himself, and in an instant, the events of last night resurfaced.
He had been in this world for ten years now. A mere child, ten years old, and a member of the Uchiha clan.
His relationship with Tsunade? A product of circumstance.
His talent was mediocre at best. Though the Uchiha clan had taken care of him as an orphan, by the time he could fend for himself at five or six, their interest waned. His peers had outpaced him. Uchiha Mikoto, his childhood friend of the same age, had already attained the level of a Genin, while he lagged behind, struggling even with basic jutsu.
For an Uchiha, that was disgraceful.
This sense of inadequacy had driven him into a spiral of self-doubt. To cope, he frequently visited the gambling dens, drawn to the thrill as a form of escape.
And that was how he got involved with Tsunade.
Unlike many in Konoha, Tsunade did not harbor hostility toward the Uchiha. As Hashirama Senju's granddaughter, she had little interest in the old grudges between their clans. Over time, their interactions grew, and before he knew it, she had dragged him into taverns, encouraging him to drink despite his protests.
Last night had been one such occasion—except this time, he had stubbornly forced down several drinks, leading to his current predicament.
"She pinned me down with her 106cm Boobs and made me drink. I'm only ten, dammit! What is wrong with this woman?!"
Recalling the painful but erotic memories of last night, Uchiha Shin didn't know whether to be angry or happy..Of course he is happy hehehe
It was a pity that he was powerless now, otherwise he would definitely have to retaliate with his dick!,
He reached out and gave her a few light pinches in retaliation, though his current strength was far from sufficient to make an impact.
"Mmh… little brat… that hurts…" Tsunade mumbled in her sleep but did not wake.
To her, he was nothing more than a child, akin to her younger brother. Even in her drowsy state, she didn't seem bothered by his presence.
Shin sighed and dragged himself to the bathroom. Splashing cold water on his face, he looked into the mirror, taking in his reflection. His youthful, handsome features were perhaps his only remarkable trait.
But right now, his appearance was the least of his concerns.
Because in the next instant, his dark pupils shifted—
A crimson hue bled into them, and tomoe surfaced, spinning within his irises.
One tomoe. Two tomoe. Three tomoe.
And then—
The tomoe connected, twisting into an entirely new pattern.
An intricate, eight-pointed design emerged.
"…Mangekyō Sharingan."
Shock coursed through him, followed by an overwhelming wave of exhilaration.
He had directly awakened the Mangekyō Sharingan!
Perhaps it was the sudden resurgence of his past-life memories, triggering the latent potential within his soul.
But his excitement quickly waned.
This world was filled with monsters. Kage-level shinobi, war-hardened legends, even celestial beings. Against the looming threats of the future—the Second and Third Great Ninja Wars, the emergence of the Akatsuki, the shadow of Madara's influence—even the Mangekyō felt insufficient.
Not to mention the inherent drawbacks.
Without an Eternal Mangekyō Sharingan, his vision would deteriorate with use. And he had no brother, no immediate way to evolve his eyes further.
"The cursed eyes… this power can't be used recklessly."
Despite that, he clenched his fists, determination hardening his gaze.
With these eyes, he could at least ensure his survival. With these eyes, he could kill a Kage-level opponent if necessary.
The next step was understanding his ocular abilities.
The Mangekyō Sharingan was unique to each wielder, reflecting their deepest emotions and desires.
Closing his eyes, he focused. When he reopened them, an overwhelming surge of information flooded his mind.
His left eye—
[Soul Rend: Reflection]
It held two functions. The first allowed him to construct abilities from his imagination, consuming both his pupil power and chakra to materialize them. The second allowed him to analyze and reconstruct techniques based on existing abilities—but the outcome was always uncertain.
His right eye—
[Soul Rend: Sacrifice]
It allowed him to absorb and convert external forces into his own strength—though at a cost.
Shin's brows furrowed. He needed to test it.
The right eye's ability required a suitable subject, so he decided to experiment with the left eye first.
His chakra affinities were Fire, Lightning, and Wind—a rare combination among Uchiha.
His first thought was to construct Chidori or Rasengan, but both were techniques he could learn naturally. Wasting his ocular power on them would be foolish.
Instead—
A more ambitious idea took root.
Bloodline limits.
Could his left eye construct one?
Focusing his thoughts, he honed in on a nature transformation that would align with his affinities.
Magnet Release.
The Mangekyō spun as his left eye activated. An intense strain shot through his body as chakra surged through his tenketsu. Blood trickled down from his eye as the ability took hold.
"Magnet Release: Magnetic Pull."
Without forming any seals, he raised his hand—and immediately, every iron object in the room trembled.
Kunai, shuriken, needles—they all shot toward him, stopping just short of his skin, suspended in midair.
Pointing toward the wooden door, he gave a silent command.
Bang. Bang. Bang.
The weapons launched forward, embedding themselves deep into the wood.
A slow smirk spread across Shin's lips.
This world had given him a second chance.
And he would make damn sure to survive in it—no matter the cost.
