With Mangekyo, I Escaped Konoha To Other Worlds [Naruto/AttackOnTitan] Chapter 3 - 2, Mangekyo, In Attack On Titan

Unfortunately, that wouldn't last long.

Thud!

A loud thudding sound interrupted his mourning.

Thud!

The boy's shaking shoulders ca to a halt. Following which, he raised his head to reveal a tear stained face and abnormally red eyes. Each one having three tomoe, signifying his activated Sharingan.

Thud! Thud! Thud!

The thuds grew louder, more rapid. And for a mont, he forgot his sorrow, peering forward to see what was coming.

Eventually, he did.

Bang!

In the distance, from between the trees, a giant foot landed on the earth. Then the rest of it ca into full view.

It was a human. A very, large, naked human. Massive it was, towering over the highest branches. Its body was abnormally shaped, with a disproportionately large head compared to its torso.

How it could walk without falling to the side was sothing Orochimaru would marvel at. With an eerily blank face, devoid of any expression, it turned itself in Seiji's direction. Its massive limbs twitched with an unnatural, almost jerky rhythm, as though it barely understood how to move.

Then it leaped into the air, landed back on the floor, and ran rapidly towards him.

It covered several feet with each step, closing the distance of less than a hundred ters in just two to three seconds.

Of course, to Seiji, it mattered little. With his Sharingan active, the creature's movents were slow, slow enough to let him process the absurdity before him.

Whatever this thing was, it was a creature he had never seen before in the Ninja world.

Yet strangely ...

'I know this ...'. He thought inwardly. '... Why do I know this?'

mories flooded his mind. Fragnts of an ani he had watched in his past life. Of Endless slaughter, of Man Eating Giants, of three walls representing the last struggle of humanity.

The world of Shingeki No Kyojin.

'I ... I'm in Attack On Titan'. The realization hit him for a mont. Then it sunk, and rising in its place was an indescribable emotion from deep within his depths.

Currently, he was experiencing a lot of emotions at once.

Pain, anger, guilt, sadness, but this one was different.

The others all stemd from the loss of his Nana, the last person in his life who he truly cared for. Anger at his weakness, sadness for her death, guilt for the circumstances in which it occurred.

This one, however, wasn't his self loathing. It was .... rage ... Pure, fiery, undulated rage.

'This stupid ability, in all possible worlds, sent to Attack On Titan?'

It started as doubt, disbelief even.

Finally realizing the true aning of Transportation to other worlds.

And the mont it sunk in, his face twisted to the extre. And conveniently, at that mont, the Titan neared, and stretched its hand for a flying leap.

He had just killed his Nana, his last relative. And fled for his life, knowing he was too weak to avenge her. Even in all that, this goddamn cheat that was supposed to help him, took him to a world where he would get eaten instead.

If the loss of Asami wasn't enough, this definitely was. At that mont, Seiji's negative emotions hit a new extre.

Within his eyes, the sharingan spun crazily, then the three tomoe connected and spread rapidly. In the blink of an eye, a new pattern was ford in his pupils.

A powerful force erged from them, infiltrating the Titan whose giant hand was barely a foot away. In less than a second, it spread through every limb, every joint, from the head to the toe.

Then it rapidly condensed inside its stomach area at the center.

The Titan knew not what would befall it. Its arm outstretched to grab the human before it and stuff him into its mouth.

Inches away... when...

Bang!

A ripple distorted the air around the Titan's body, as if reality itself had montarily twisted. The naked giant's movents faltered—the hunger in its eyes replaced with sudden confusion. Its hand trembled midair, unable to move forward.

Its skin paled. Its flesh loosened.

Then, like a puppet with its strings severed—

Squelch!

The Titan collapsed. Its body convulsed, its chest heaving as if gasping for breath it could no longer take. Seiji watched as its towering form shrunk, its muscles caving inward—its very existence unraveling as the power animating it flickered away.

The Titan's massive fra withered like dried parchnt, steam hissing violently from its skin. Within seconds, its body slumped to the earth, no different from a decayed husk.

Its arm, once reaching for him with relentless hunger, now twitched weakly... before falling still.

The Titan was no more.

Seiji exhaled. He had not struck a single blow—yet his eyes alone had erased the beast's defining strength, severing its monstrous transformation and returning it to what it should have been—nothing.

A sight that left its creator completely astounded.

Paradis Island

Wall Maria

---

It was early in the afternoon. The sun shone high in the sky, fueling the perpetual blistering heat.

Impacting the soil freely in so areas, while the trees huddle together to provide cover for its inhabitants in others.

The wind blew, this ti bringing not the fresh scent of nature, but rather a weird odor from a decaying body.

The Titan laid still, steam was emitting from its corpse, or whatever was left of it, but Seiji paid it no heed.

'... What ... What just happened?'

The young Uchiha thought, inwardly marveling at what had just happened.

It happened then.

"Ugh". From out of nowhere, a pain erged in his body. It was slight, not much compared to what he had gone through in his life and could completely be ignored.

The difference, however, lay in the fact that he didn't do anything worth receiving pain.

Well, he didn't think so at first. Until he felt the change in his ...

'... My eyes ...'. Seiji thought as he felt his pupils, instantly understanding the cause of all this.

Mangekyo ...

The reason his grandmother sacrificed herself, his Nana's final help to him, was aiding his process to awaken these eyes.

'... I see ... In that case, I did this?' When awakening his mories and learning his situation, he had also wished to possess these eyes.

Especially when he realized his cheat wasn't a system. That wish only intensified.

The ultimate power of the Uchiha clan, as the elders knew it. Without possessing it, he would be incapable of influencing Uchiha's fate.

Now he had it.

Seiji didn't need to look in a mirror to know his eyes had evolved.

The basic increase in dynamic vision compared to three tomoe was exaggerated enough to leave him with no doubts.

The raw, unrestrained power coursing through his eyes. The vision in front of him was sharper, more vivid, as if he could see every detail of the field, the smallest flicker of movent in the trees, the rise, and fall of his own breath. Even the steam emanating from the dismbered Titan seed slow, like every second could be stretched to an infinity.

The world .... It all felt too clear, too defined.

However, he had no joy for his newfound power. In his heart was nothing but endless sorrow.

The Uchiha Clan was already massacred. Technically speaking, only five blood mbers of the Uchiha were left alive.

One wasn't in the sa universe and one had been sealed away for years.

The main reason he needed these eyes in the first place was used to awaken them. It didn't matter what he had obtained, Seiji couldn't muster up the slightest bit of joy.

Not to ntion ...

This level of clarity ca at a cost.

A sharp, stinging sensation spread out of his eyes, pulling him out of his thoughts. Warm liquid flowed down his cheeks.

".... Blood?"

He raised a hand and wiped his face, his fingers ca away sared with red.

'This is it .... The price of Mangekyo. The drawbacks are already taking effect'.

This blood wasn't just a sign, it was a reminder. A reminder that this power would erode his very vision the more he relied on it. And the pain, while mild now, would worsen.

Seiji took a deep breath, closed his eyes and deactivated the Mangekyo back to Three Tomoe. The strain eased, but the weight of his situation did not. His body was exhausted, and his chakra reserves were alarmingly low.

'.... That single move'. He thought glancing at the Titan remains steaming in the midday sun. 'Took more than 80% of my chakra. Even factoring my constant use of Body Flicker back in Konoha, this isn't good'.

He let out a shaky exhalation. It wasn't just the Mangekyo's price he had to contend with. The sheer energy it consud made prolonged battles with it impossible.

'.... Weren't Uchiha's supposed to gain more chakra after awakening this thing? Where's mine?'

He thought as he stood to his feet. For now, he needed to move. But before he could take another step, sothing changed.

"Ugh!" A surge of information flooded into his mind, overwhelming him.

'The Interdinsional Gateway...'.

His Transmigrator gift had been silent ever since the first day of awakening. Today however, it finally had a response.

Just like his first awakening, the knowledge of what it wanted to pass on, clarified itself. Unraveling piece by piece.

[World Travelling]

Each New World Unlock Requires A Year's Cooldown]

To Return To An Already Visited World, The Cooldown Ti Will Be Halved]

Each Subsequent Return Visit will Cut The Ti By Half Until It becos Negligible]

The Ti flow Between Worlds is 1:5]

Ti Adjustnts will be Made as More Worlds Are Unlocked]

How long the transfer process took was unknown, as Seiji had lost his sense of ti. Just like he had suspected, rules would be made clear after his first world travel.

The implications here were imnse, clearly displaying he was right to fear if he could return once he left.

If he wanted to return to The Ninja World, he would need to wait for six months. This was rely his own perception of ti.

In reality, Two and a half years would have elapsed back in Konoha. Then unless he had an already open world, he would have to stay there for another half a year to either transverse to a new world or return to Attack On Titan.

Effectively squashing whatever ideas he once had of moving back and forth between worlds as a form of evasion.

The surge of knowledge ceased, allowing him to regain his perception of his surroundings.

'.... Well that was ....'. He froze then, senses blaring with alarm.

The wind whistling behind him, the ground vibration, and the shadow that enlarged rapidly under the insight of his Sharingan.

'.... Oh, shit!'.

BANG!

The earth trembled as a Titan erged from behind, it's massive mouth open as it lunged forward and bit down into its target.

The jaws snapped shut on empty air where Seiji's head should have been a mont earlier.

The boy himself reappeared several ters away, panting as he let the chakra flow settle.

'That ..... That was too close'.

He gently placed his Nana's corpse on the ground, his chest rising and falling in frustration.

'.... This stupid cheat'. He thought, his previous burning anger returning. 'Is it hell-bent on trying to kill ?'

It was a class 7 Titan (7 ters), large and currently stood on all fours. It was impossible for a Chunin not to notice such a bird at close distance, much less sothing this large.

Yet in that mont, the Interdinsional Gateway had flooded him with so much information that he couldn't pay attention to his surroundings.

He was almost eaten twice, the second much closer than the last.

In anger, the young Uchiha unsheathed his Chakra tal blade, the steel glinting under the sunlight.

The Titan, oblivious to its failure rushed in his direction. An action which he reciprocated.

'You're in my way'.

Chakra surged to his feet, his movents were fast as he kicked against the ground with explosive force.

It took him into the air, perfectly dodging the mindless creature as he slashed his weapon at the place he knew would kill it.

The Nape.

SQUELCH!

The massive body collapsed to the ground, steam billowing into the air as the regeneration halted.

It ended quite fast.

Seiji let out a breath, his anger down as the adrenaline faded. Nevertheless, the second attack was a wake-up call.

Seiji rembered the Attack On Titan ani.

A group of people who thought they were the last of humanity, battling against Giant humanoid monsters whose sole purpose was to feed on them.

Judging from this, he knew he was sowhere on Paradis Island, the main location of the plot.

In his current state, with low chakra reserves and emotional instability, the last thing he wanted was to be sward by these creatures from all directions.

Staying here was suicide. Hence, he needed to leave, fast.

Carefully, he sealed Asami's body into a storage seal and examined his surroundings before leaping into the trees.

A Ninja's most valuable asset was information. Trapped in this world, what he needed now was to know exactly where he was.
