Star City, deep underground in the military zone.
In a quiet room constructed of heavy alloy and complex sealing runes, Menma sat cross-legged.
Inside a quiet room constructed of heavy alloy and complex sealing formulas, Menma's true body sat cross-legged.
The white three-eyed fox mask lay beside him. Beneath his black short hair was a young face, yet one settled with a steadiness far beyond his years.
The memory of being washed over by the vast Chakra and Ocular Power during contact with the Giant Tenseigan surged like a powerful undercurrent, violently colliding and settling within his mind.
He slowly closed his eyes, his spirit becoming deeply calm.
The immense, ocean-like Chakra within his body was precisely guided, transforming into a rushing torrent that surged through specific pathways, violently flowing toward his eyes, where it was continuously refined into ocular power, scouring them.
His left eye, that crimson Three-Tomoe Sharingan, was the first to ignite.
The three tomoes began to rotate, their speed increasing, their trajectories growing more and more blurred, as if struggling to break free from the confines of the socket and tear apart their original form.
An intense, burning pain erupted from deep within the eyeball, like a red-hot iron being pressed repeatedly against the optic nerve.
"Hmph." Fine beads of sweat instantly appeared on Menma's temples, but his body remained as steady as a rock. His powerful will held his mind firmly in place, guiding the immense power within him to continue impacting the Sharingan.
He could clearly 'see' internally the high-speed rotation of the tomoe, their trajectories beginning to elongate, twist, and deform, the boundaries between them becoming indistinct.
The lines of the three tomoes intertwined and merged within the extreme rotation, finally collapsing and reorganizing to form a new, profound, and mysterious pattern.
A black vortex that seemed capable of swallowing all light!
At the very center of the vortex, a point of ultimate nothingness quietly condensed.
The instant the pattern in his left eye fully formed, a surge of understanding erupted from the depths of the eyeball.
The true name of the Mangekyo's Dojutsu was branded deep into his consciousness… Ame-no-Minakanushi!
This newly born eye technique, containing a certain destructive power, was like a massive rock thrown into a lake, provoking a powerful resonance in his right eye.
The Akaigan, usually as beautiful as a ruby, capable of perceiving Chakra Flow and interfering with the Byakugan, now seemed like an awakened beast, transmitting waves of scalding palpitations.
Menma's thoughts moved like lightning. Without hesitation, he diverted a stream of pure, immense Ocular Power, unique to the left Mangekyo, and actively guided it, forcefully injecting it into his right eye!
Hum-!
The Akaigan on his right eye suddenly erupted with an unprecedented, piercing red light!
His vision was instantly flooded by a boundless tide of blood red, as if he were standing in a molten lava hell.
A tearing, intense pain shot through his eyeball, as if the entire eye was about to be burst and melted by this foreign, higher-level Ocular Power!
Menma gritted his teeth, letting out a suppressed groan. His body trembled slightly from the intense pain, but his powerful mental will acted like an immovable pillar, firmly anchored, guiding this violent alien Ocular Power through a difficult process of fusion and reshaping with the right eye's own power.
He could feel the internal structure of his right eye undergoing a deeper level of transformation. Within the blood-red world of his vision, even clearer, more ethereal 'lines' began to appear.
Perhaps because this evolution wasn't triggered by intense emotional stimuli like a typical Sharingan's, this process of metamorphosis through Ocular Power scouring was both painful and prolonged, feeling as if it were remolding the very senses of his soul.
After an unknown period, the storm of violent energy within the quiet room finally subsided, leaving behind only absolute silence.
Menma slowly opened his eyes.
In his left eye, on the scarlet background, the deep black vortex pattern slowly rotated. The point of nothingness at its center seemed to connect to an endless abyss, emitting an aura that made one's soul tremble.
The ruby-like color of the right eye had settled, becoming deeper and more restrained. Deep within the pupil, an indescribable ripple flashed like a fleeting wave before vanishing, returning to normal.
But Menma clearly perceived that its power of insight and interference had leaped to an entirely new level, its perception becoming even more keen and subtle.
He slowly raised his right hand, palm facing upward. With a slight focus of his will, the vortex in his left Mangekyo's pattern seemed to come alive. An invisible force quietly gathered in his palm.
This wasn't a condensation of Chakra, but a manifestation of a rule brought forth by the Mangekyo's Dojutsu.
He gazed at the core of this power, deciphering the essence of [Ame-no-Minakanushi].
"Erase and Delete..." He murmured to himself, interpreting its meaning.
'Targeted existence traces... conceptual connections... narrative layer erasure... This Dojutsu has already surpassed the instinctual emotion-based evolution of the Sharingan. Its 'reality-warping' characteristic is more like a form of higher-dimensional interference authority.'
'Just like… just like an author deleting certain settings from their work!'
Menma's thoughts raced at high speed, combining his fifteen years of struggle within the [Limited Tsukuyomi World] and his unique understanding of the "Naruto world" as a transmigrator.
This Dojutsu, [Ame-no-Minakanushi] was far from simple physical annihilation.
It targeted 'existence' itself, operating on the rules that constitute the world!
It could sever the strongest 'bonds' between people, turning comrades who shared life and death into strangers… it could also erase the core contractual link between a Jinchuriki and their Tailed Beast, no longer requiring sealing techniques… a single glance could cut off the Jinchuriki's Tailed Beast Chakra!
It could even 'erase' Cursed Seal and Sealing Techniques like the Caged Bird!
It could directly delete a target's connection to the source of their power core, such as the bloodline-level authority Shuto and Toneri held over the Giant Tenseigan!
An even grander, near-mad idea formed in Menma's mind: 'If this Dojutsu continues to evolve to a higher level, could it become like Ada's [Omnipotence] in Boruto, directly twisting and rewriting the cognition of everyone in the world?'
'Even in the future, when these eyes evolve to a higher form, could they ignore the fundamental rule that allows the Otsutsuki Clan to dominate the universe, the rule of 'vessels'?'
'Could it directly invalidate their [Kama]?'
"The power of the narrative layer..." Menma's fingertips unconsciously traced the void before him. The spiral pattern in his left eye shimmered faintly, as if echoing this transcendent conjecture.
He faintly sensed that this power, born from painful evolution, seemed to touch upon a realm that surpassed the current physical rules of the Ninja World. It held a mysterious connection to his identity as a [Transmigrator]… a variable that should not exist within the 'script'.
This was perhaps the most incredible and most fitting gift Menma had received from that false yet deeply etched [Limited Tsukuyomi].
With this thought, Menma concentrated his Ocular Power!
The Mangekyo's pattern in his left eye suddenly began to spin rapidly!
[Dojutsu: Ame-no-Minakanushi!]
Deep within the moon's Giant Tenseigan, the blue threads of light representing access permissions, invisible to ordinary people, snapped and dissipated one after another, utterly powerless to resist!
It was not destruction, but a complete erasure from the conceptual level of 'existence'!
'Deletion complete.'
'From this moment on, the Giant Tenseigan would recognize my authority alone.'
Menma picked up the white three-eyed fox mask again and gently placed it over his face, concealing his heterochromatic eyes.
…
Star City, the administrative district on the east bank of the Yukawa River-
The family compound area featured a mix of architectural styles, blending traditional clan courtyards with new terraced apartments.
Across a meticulously manicured lawn, opposite Kanon's residence, stood a newly completed courtyard built from the same grey-white stone but in a more ancient and simplistic style.
Above its gate, there was no clan's crest, only a new, plain white stone plaque, still uncarved.
This was the new residence of the Otsutsuki father and son.
Deep within the mansion, in a softly lit quiet room-
Hikari and Shisui stood on the engawa, leaning against a pillar.
Hikari's gaze was fixed on the moon in the night sky, while Shisui watched the procedure inside.
Inside the room, Kanon had fine beads of sweat on her temples. Her hands, wrapped in precise, pale green Chakra, gently moved away from the eyes of Toneri, where the surgery had just concluded.
"All done." Kanon's voice was warm and encouraging, "Go on, try to feel its presence."
On the bed, the young Toneri kept his eyes tightly shut, his long white eyelashes fluttering slightly from the pain and intense foreign sensation.
At Kanon's signal, he tried, extremely slowly, with a mix of fear and anticipation… he opened his eyes.
A glimmer of light.
Soft but unfamiliar light entered his optic nerves directly for the first time, not simulated through his [Mind's Eye].
Unlike the monotonous lines of energy flow perceived by the Mind's Eye, what lay before him was colored, blurry, with post-operative double images and halos of light outlining the figure before him.
Kanon, with her vibrant red hair tied up, wearing a white coat.
Sitting by the bed, Shuto used his Mind's Eye to carefully, repeatedly 'trace' his son's outline.
"Father..." Toneri suddenly spoke, his voice carrying a hint of cautious testing and irrepressible excitement.
He slowly, as if mustering all his strength, opened those eyes… which originally belonged to a Hyuga Clan's elder.
His eye sockets were no longer filled with suffocating darkness!
Bright light, carrying the warmth of color, flooded into his vision, so real and clear for the very first time!
Although there was still some haziness, an uncomfortable sensation like looking through a thin veil, he could truly 'see'!
He saw the soft, delicate textures on the ceiling, the warm light filtering through the window, dotted with golden specks, and he saw his father's face by the bedside… deeply lined, etched with fatigue and hardship, yet so familiar from his [Mind's Eye] perception.
Those newly acquired Byakugan now clearly reflected his father's weary face.
"Toneri... you… you can see?" Shuto's voice trembled with disbelief and a sense of near-liberating relief.
Through his Mind's Eye, he 'saw' the visual spark rekindled in his son's eyes. His heart, once frozen solid by twisted obsession, finally thawed completely at this moment.
"Yes! Father, I can see! I can see! I can see what you look like!" Toneri sat up abruptly, excitedly reaching out with slightly trembling hands to tightly grasp his father's thin, withered hand.
His gaze greedily scanned every corner of the room before finally settling once more on his father's face, weathered by time. His voice choked up: "So this… this is what the area around your eyes looks like-"
Shuto gripped his son's hand tightly in return, his knuckles turning white from the force. He tried to squeeze out a nearly kind smile on his wrinkled face, though it looked particularly bittershadowed against his failing health.
"Good... good that you can see. That's all that matters..." He let out a long, deep sigh, as if shrugging off heavy chains he had carried his whole life. His tone became unprecedentedly solemn.
"From now on, follow Shura-sama. Go... and see..." He seemed to want to describe a scene, but his words faded into a silent, understood blankness.
The joy on Toneri's face instantly froze. Looking at his father's deteriorated and withered face, immense sorrow welled up in him, and his eyes reddened instantly.
But Shuto just shook his head firmly. His clouded [Mind's Eye] seemed to pierce through the roof, gazing at the sky of the Star City.
"Do not grieve. To witness you regain your sight with my own perception, my obsession is fulfilled. The new life granted by Shura-sama, the chance for our clan's survival, deserves our utmost loyalty in return."
Toneri nodded vigorously, tears falling onto their tightly clasped hands.
Within those newborn Byakugan, for the first time, towards this unfamiliar world and towards that powerful, god-like figure wearing the white three-eyed fox mask, besides the awe born of absolute power, a sense of genuine, weighty belonging quietly took root.
Under the night sky of the Star City, the direct descendants of Otsutsuki Hamura took root quietly on the banks of the Yukawa River.
