Inside the spacetime analysis room at the Divine Court headquarters, blue data-patterns flowed across the surrounding walls.
In the center of the room, a massive jutsu sand-table glowed, projecting an accurate 3D map of the shinobi continent.
Shinju, Tobirama, and Kakashi stood around the sand-table, discussing the same topic as before—Obito's Kamui dimension.
"Obito's Kamui is, in essence, the transfer of himself or anything he touches into an independent alternate space," Shinju said, making everyone present feel a quiet chill.
Spacetime ninjutsu could be used like that?
"That space is his safest shelter. Conventional spacetime ninjutsu can't track its exact coordinates. So, to a certain extent, it guarantees Obito's safety."
Tobirama stared at the void region beyond the sand-table's map—an area representing unknown dimensions—his brows knitting tighter as his expression darkened.
"That's right. Flying Thunder God requires leaving a formula in the real world as a coordinate point. For a completely independent dimension, my spatial perception might not be able to reach it."
Kakashi unconsciously covered his left eye. Pain pulsed through the transplanted Sharingan in steady waves.
"My eye can resonate with his space in some way. I can only passively send objects in, or pull things out from inside. I can't actively enter that space, and I can't determine its exact location either."
Shinju looked at the two of them—one the pioneer of spacetime ninjutsu, the other a copy-ninja genius wielding a special Mangekyo Sharingan.
And yet even for these two geniuses, this problem could stop them cold.
"That's because your thinking is still stuck at the 'ninjutsu' level."
He stepped to the sand-table and swiped across the light screen, pulling up a series of complex data models.
"Any space has its own unique frequency—just like everyone's voice is different. Obito's Kamui space and your left eye, Kakashi, share the exact same spatial frequency. That's the fundamental reason you can resonate."
He turned toward Tobirama.
"Tobirama-sama, your Flying Thunder God can sense the 'fluctuations' of space itself. And Kakashi, your Kamui can emit a 'frequency' that matches the target space."
"Now what I need you to do… is combine the two."
Tobirama and Kakashi exchanged a look, both seeing the same shock in the other's eyes.
Combining two spacetime techniques with completely different principles and properties—neither of them had ever even heard of such a thing.
"Tobirama-sama, I need you to use Flying Thunder God's spatial sensing to capture the extremely faint spatial frequency leaking from Kakashi's eye when he activates Kamui," Shinju said to Tobirama.
Then he turned to Kakashi.
"Kakashi, I need you to concentrate all your ocular power into a single point—aim at the 'imaginary coordinate' I've marked in the center of the sand-table—and unleash Kamui at full power."
Shinju marked a flashing point inside the void region.
"I'll use my chakra as a 'bridge' between the two of you—synchronizing and amplifying your power to ensure the frequency doesn't distort."
Tobirama and Kakashi didn't hesitate.
They moved immediately according to Shinju's instructions.
Tobirama closed his eyes. His vast sensory field expanded outward, completely enveloping Kakashi beside him as he examined every subtle change in the surrounding space.
Kakashi lifted his forehead protector, revealing the crimson Sharingan.
He took a deep breath. The three tomoe in his eye began to spin, rapidly forming the distinctive Mangekyo pattern.
He gathered all his ocular power, locking his gaze onto the marked point on the sand-table.
"Kamui!" Kakashi shouted.
The air around Kakashi warped strangely as an invisible suction force erupted from his left eye—almost as if it would drag nearby objects straight into that space.
At that moment, Shinju suddenly extended both hands, placing one on Tobirama's shoulder and the other on Kakashi's.
Under Shinju's chakra amplification, Tobirama's sensory ability—already terrifying—shot up several levels in an instant.
There was no strongest—only stronger.
He "saw" it.
Within the twisted spatial distortion around Kakashi's left eye, there was a one-of-a-kind frequency.
This had to be it.
Tobirama snapped his eyes open.
His hands formed seals at rapid speed, encoding and re-recording that unique frequency into Flying Thunder God's formula—then imprinting it onto the jutsu sand-table.
On the sand-table, the coordinates representing the Kamui dimension were completely locked.
A standalone space drifting outside the main world—successfully anchored.
Even if Obito racked his brain, he'd never figure out how his backyard had been breached.
"Incredible. No one in my era ever thought of such a method," Tobirama said, staring at the clear coordinate now displayed on the sand-table. "So spacetime ninjutsu can be reverse-tracked like this… locking onto an independent dimension through resonant frequency. Your knowledge and ability… it's like it comes from another world."
Kakashi clutched his left eye, gasping for breath as the stabbing pain surged.
His shock was no less than Tobirama's.
He'd never imagined that this eye—an endless source of pain and trouble—could become a "key" to opening another world.
He gave a self-mocking chuckle. "So this eye can actually be useful… maybe it's not completely terrible."
Shinju looked at the successfully marked coordinates on the sand-table and smiled faintly.
Now it was finally done.
With this, they would have far more confidence when dealing with Obito later.
"Obito thinks the Kamui dimension is his safest shelter. But he doesn't know that any room with a lock—so long as there's another key—can be opened from the outside."
"Kakashi, your eye is that key. And now… it's time to settle the cause and effect between you two."
From a nearby console, Shinju picked up a metal spike specially made by Tobirama based on the coordinate data.
The spike was covered in dense Flying Thunder God formulas and spatial stabilization formulas.
This object clearly wasn't ordinary—it had a specific purpose.
He placed the "dimensional beacon" into Kakashi's hand.
"Next time you activate Kamui, take this inside. It'll become an unremovable coordinate—permanently anchoring that space. When that happens, the Kamui dimension will no longer be a secret to us. It'll become a backyard we can enter and leave at will."
"Think of it like a lighthouse at sea—so long as the lighthouse is still operating, we'll always be able to find the target."
Kakashi took the heavy beacon and nodded.
Uchiha Obito's greatest pride—and his final life-saving trump card—had been completely cracked through Shinju's beyond-the-era knowledge, combined with the forbidden techniques of two top-tier shinobi.
Everything was ready.
But Shinju didn't immediately give the order to move.
To truly crush Obito, brute force suppression was only secondary.
Breaking his heart—that was the best strategy.
Shinju's gaze shifted toward Konoha's Memorial Stone.
There, one long-sealed name waited.
Nohara Rin.
