When he learned the devastating truth of his mother's death…
In that instant, Mirai felt an overwhelming desire to escape everything — to destroy everything.
It was that desire which awakened the Mangekyō's abilities.
One was Kamui Intangibility, a technique that allows him to ignore incoming attacks and techniques entirely.
The other was Kamui Annihilation, a spatial technique capable of crushing through any defense.
When Zenin Ogi struck him with a blade fully reinforced with cursed energy, the attack had not missed.
It had simply passed through him — avoided via intangibility.
And the strange phenomenon that instantly killed Zenin Nobuaki was Kamui Annihilation's spatial severance.
The abilities were nearly identical to Obito's ocular techniques from another world — though not completely the same.
After activation, the Sharingan's growth and usage relied not on chakra, but on cursed energy in this world.
Mirai also did not need to fear blindness from overuse of the Mangekyō.
The cursed energy he absorbed constantly not only replenished ocular strain but could even enhance the abilities of his eyes further.
All of this knowledge had surfaced in his mind the moment he awakened them.
He also finally understood why he had been born with abnormally low cursed energy.
Aside from the Mangekyō itself, two items residing within the Kamui dimension were the true cause.
The partially unsealed Demonic Statue of the Outer Path, transformed by this world's laws into the body of a cursed spirit.
And the misplaced supreme cursed tool — the Uchiha Gunbai, capable of reflecting cursed energy attacks.
Before Mirai awakened the Sharingan, these two objects had remained hidden within the Kamui space, unconsciously absorbing surrounding cursed energy.
Only after awakening did Mirai gain preliminary control over that space.
Through the Sharingan as a medium, the boundless cursed energy absorbed by the Demonic Statue became his to command.
And once his cursed energy swelled to sufficiency—
The Ten Shadows Technique naturally awakened within his shadow.
Sliding open the wooden door, Mirai grabbed a pillow and lay down in the corridor, staring up at the dim stars, thoughts drifting.
Yesterday had been his first true test of the Demonic Statue's intimidation.
He was satisfied.
Even in its initial awakened state, it already carried the aura of a Special Grade cursed spirit.
He had awakened at age six.
It took four years to familiarize himself with the surge of power — and to subdue the nine shikigami of the Ten Shadows Technique.
Only after completing preliminary control over the Demonic Statue last night had he finally carried out this series of "greetings."
When he first transmigrated, Mirai had planned to enroll in Jujutsu High and rely on the protagonists to survive until the end.
But everything he had endured within the Zenin Clan taught him a profound truth:
Relying on others will never compare to relying on oneself.
After all, even someone as strong as Gojo Satoru ultimately became "2.5 Gojo."
If there must be a strongest—
Why shouldn't it be him?
The Next Morning
A low-ranking member of the Kukuru Unit stared nervously at the boy lying in the corridor.
Swallowing hard, he called softly:
"Sir… Sir."
" Mirai-sama, please wake up. The clan head and the others are waiting for you in the meeting room."
Mirai opened his eyes and glanced at the cautious figure standing at a distance.
"Wait."
Just two cold words.
Then he rose and returned to his room to wash and change.
Ten minutes later—
The ruins from yesterday had been completely cleared. The corpses buried beneath shattered tiles had vanished.
Even the scent of blood had been purified.
No trace remained of the carnage half a day prior.
Servants and sorcerers alike lowered their heads in reverence as Mirai passed.
Yesterday's events were still vivid in their minds.
The Meeting
In the spacious conference room, only two of the Zenin Clan's so-called upper echelon were present.
There should have been three.
One had "moved house" the previous night.
Clan Head Naobito leaned against the table, drinking deeply from his sake gourd.
Beside him stood a burly man with a full beard, impatience evident on his face.
His messy black hair bristled like a hedgehog's quills. A vicious cross-shaped scar split his forehead, giving him a wild, dangerous aura.
Zenin Jinichi.
Overseer of the clan's external businesses and intelligence network.
A powerful Grade 1 sorcerer.
Naobito felt momentarily dazed looking at Mirai.
Compared to last night's blood-soaked executioner, today's Mirai — dressed in clean white garments, handsome and composed — seemed like a completely different person.
As for Jinichi, he had not been present last night.
Though Naobito had described everything, he still could not fully believe that this mere boy had publicly slaughtered Zenin Ogi — a fellow Grade 1 sorcerer.
Watching the calm child approach, Jinichi's suspicion grew.
Three parts doubt.
Seven parts scrutiny.
Cursed energy surged within him, pressure rising sharply.
Whether true or not—
A test would reveal it.
The invisible oppressive force unique to a Grade 1 sorcerer descended toward the boy.
Mirai halted.
A cold smile curved his lips.
So last night's demonstration hadn't been decisive enough.
His black pupils turned blood-red instantly.
"Jinichi!!"
The surge of cursed energy beside him made Naobito's heart lurch.
Cursed energy reinforced his legs. In less than a fraction of a second, Naobito bent low and rammed into Jinichi's waist, blasting him through the doorway.
Jinichi barely registered the sonic boom in his ears or the splintering crash of the wooden door.
White shockwaves still rippled through the air. Wood fragments scattered everywhere.
"Are you trying to die?!!"
Before Jinichi could recover from being slammed onto the concrete outside, Naobito's furious shout rang out.
Turning toward Mirai inside the room, Naobito quickly explained:
"Mirai, forgive this old fool once."
"He was out handling clan affairs last night and just returned."
Ten-year-old Mirai stood in the corridor, barely 1.6 meters tall.
Yet as he looked down at Jinichi sprawled on the ground, the dominance felt reversed.
Under the boy's blood-red gaze, Jinichi suddenly felt a chill crawl down his spine.
A reflexive shiver ran through him.
After a moment's thought, Mirai shifted his gaze to Naobito.
"I'll give you face this time, old man."
"But if there's another idiot like this next time, I won't hold back."
Last night's purge had already cost the Zenin Clan heavily.
If he eliminated Jinichi — the clan's effective external controller — the clan would become far less convenient as a tool.
For that reason alone, Mirai spared him.
Naobito nodded.
But a trace of bitterness rose in his heart.
Being clan head like this… was truly suffocating.
Standing in the courtyard, Naobito spoke plainly:
"The Zenin Clan's upper ranks are here. What exactly did you wish to announce?"
Mirai's answer was calm.
"You should step down."
"The position of Zenin Clan Head would suit me better."
Jinichi, halfway to standing, froze in disbelief.
Good grief.
You're even more direct than your dead father.
Naobito's lips twitched.
And when he met Mirai's utterly serious eyes—
A powerful premonition struck him.
If he refused—
He might die.
