Thinking about it, Ren couldn't help frowning.
The Mangekyō Sharingan's drain was terrifying—and that was with his Sage Body supporting him.
Which meant—
He could only imagine what Uchiha Madara, Shisui, Itachi, and the others had endured every time they forced their Mangekyō open and paid the price.
"I have to evolve it… into the Eternal Mangekyō Sharingan."
His eyes hardened as he muttered to himself.
"Only the Eternal form is the Mangekyō's true peak."
Everyone knew it: to resist the Mangekyō's backlash, you needed either—
the Eternal Mangekyō Sharingan, orHashirama's cells (or something equivalent)
Ren had originally considered the second option—using First Hokage cells to blunt the Mangekyō's side effects.
But after thinking it through…
The Eternal Mangekyō was safer. More stable.
And besides—
With his Hashirama Senju Sage Body, he had zero interest in grafting in "Hashirama's cells" on top of it.
In the canon timeline, only two confirmed Eternal Mangekyō users existed:
Madara, who evolved it by transplanting Izuna's MangekyōSasuke, who evolved it by transplanting Itachi's Mangekyō
For Ren to obtain it "normally," he'd need a blood-relative Mangekyō pair to fuse.
Which was basically impossible.
He didn't have a brother.
And he wasn't about to go down the tired road of "killing family for power."
So that left one realistic path:
The System.
"At the end of the day… I still have to rely on the System."
He took a slow breath.
"System. Show me my latest status panel."
Ding… User status panel generating!

"So many abilities… the System's using ellipses now."
Ren let out a quiet, amused breath.
After ten years of sign-ins, even he couldn't fully quantify his strength anymore.
He'd signed in everywhere in Konoha that mattered—everywhere except the Hokage's office.
And his physical foundation?
That wasn't even a debate.
Peak Whitebeard + Sage Body + Lightning Chakra Mode…
Just imagining it was absurd.
A standard Kage-level shinobi might not survive a single clean punch.
"Perfect. I'll go to the Military Police Force."
He moved immediately.
The Military Police Force: A Hollow Shell
The era had changed.
After being forced to relocate to Konoha's outskirts—and after years of suppression by the village leadership and hostility from other clans—
the Konoha Military Police Force had withered into something pathetic.
When Ren arrived, there wasn't even a guard at the entrance.
Inside, only a few Uchiha remained—sparse, listless, barely pretending to work.
Ren's expression didn't change, but inside he sighed.
He knew why.
The real manpower wasn't here.
It was back at the Uchiha district—where the hardliners were pressuring Fugaku, pushing for open confrontation.
For years, the village leadership had kept testing the Uchiha's limit.
And just a few days ago—
They promoted Itachi to ANBU squad captain.
That was the final insult.
The clan's patience snapped.
They were done with a slow death.
They wanted a clean break—
Even if it meant mutual destruction.
Ren's eyes narrowed slightly.
"Wait…"
He remembered the canon timeline:
Not long after Itachi became an ANBU captain… the Uchiha were wiped out.
"But Shisui hasn't even been taken out by Danzō yet."
"So… is the massacre night being dragged forward?"
For the first time in a long while, Ren felt something close to urgency.
If his presence had caused a butterfly effect—
Then he needed to prepare now.
The Sign-In
Ren entered his office, face calm.
"System. Sign in—Konoha Military Police Force."
One second… ten seconds… thirty…
Finally—
Ding… Congratulations, User! You have successfully signed in at the refreshed location: Konoha Military Police Force.
Ding… Reward obtained: Eternal Mangekyō Sharingan Advancement Card.
Ding… Reward has been stored in System Space. User may view it at any time.
"System. Show it."
[Eternal Mangekyō Sharingan Advancement Card]
After use, the User may fuse any Mangekyō Sharingan and evolve their own Mangekyō into an Eternal Mangekyō Sharingan.
Ren went still for a beat.
Then the corner of his mouth lifted—slow, sharp, and satisfied.
So that was it.
The System wasn't just giving him power.
It was telling him—
The storm was already here.
