"Tobirama, you saw the panel's line about 'Extracted Time-Space Matter,' didn't you?"
Kazuki's phantom explained: "What I need from you is to bring back the Shibai Remains from this dimension. The energy contained within is of the highest tier I can currently reach—and it is a type I'm certain I can absorb."
"This is something I cannot do myself. I have no choice but to entrust it to you, Tobirama…"
With that, the phantom poured a stream of consciousness into Tobirama's mind.
It was knowledge of the laws governing energy flow between different dimensions.
Across the timelines of this universe, the transfer of energy was fundamentally forbidden. Stealing energy from one timeline to another would trigger the violent rejection and backlash of spacetime itself.
An otherworldly existence descending into this space would be branded the moment they arrived.
The stronger the intruder, the longer they lingered, the more they used powers alien to this world or seized its native energy—the heavier the mark would grow.
Eventually, when the mark reached a certain threshold, it would provoke a catastrophic collapse-level rejection of spacetime.
Even Kazuki himself had to fear such law-bound might.
The stronger you were, the easier it was for spacetime to detect you—and to unleash unpredictable terrors upon you.
Compared to seizing by brute force, the wiser path was to send an emissary of suitable strength.
And Senju Tobirama was just such a candidate.
"So… do you understand now, Tobirama?"
"The so-called Blind Date System is in truth a modified dōjutsu I crafted for you. You must choose a powerful individual of this dimension. By stirring her emotions, you will draw forth her native aura—thus gradually unlocking your own powers that do not belong to this world, without drawing the rejection of spacetime."
Kazuki's phantom continued: "And when you succeed in winning over your target—your blind date partner—you must bring her back to our world. At that time, the combined native aura of the two of you will be enough to conceal the Shibai Remains."
"So, that requires the two of you to have good compatibility…"
"The Shibai Remains, as the husk left behind after the Ōtsutsuki God transcended, contain an astonishing density of energy. But due to their self-sealed state and superdimensional nature—and with each time-space encouraging its native individuals to act like pirates, while repelling outsiders who attempt to plunder—"
"If you're fully prepared when taking it away, it won't provoke overly strong rejection from the alternate time-space."
"I'll also be waiting for you amidst the storm of timelines, ensuring nothing happens to you. Remember, Tobirama—if you encounter difficulties, then abandon the search for the Shibai Remains and focus only on the matchmaking!"
"You and I are bound by a soul imprint. I can always bring you back to life."
Senju Tobirama gave a heavy nod. "I understand everything, Kazuki!"
He understood clearly…
More than a blind date, Tobirama preferred to call this a war—a war preparing the way for Kazuki to completely slay the Ōtsutsuki God.
He still wanted to ask more questions.
But Kazuki's phantom dissolved at that very moment, leaving behind only the transparent matchmaking system panel.
Tobirama shook his head with a faint smile.
Now that felt right.
He knew Kazuki wouldn't force him into something as dull as a blind date. There had to be something deeper behind it all.
"Faced with such a thorny problem, Kazuki had no choice but to trust me… There's no helping it. With the shinobi world having just entered peace, there's no need to speak of enemies we may never encounter to anyone else…"
"The only one who can both understand Kazuki's thinking and execute his plan smoothly—while also earning his trust—is me."
At that thought, Tobirama straightened his collar, ready to take this journey into an alternate time-space seriously.
Since Kazuki had entrusted him with the mission, as an excellent shinobi there was no reason not to see it through.
"First, I must determine the point in time… At present, I'm eighteen?" Tobirama studied his hands closely, recalling history even as his eyes scanned the surroundings.
After all, this was an alternate time-space.
It was only natural that there would be discrepancies from the history he had lived.
"I must use the events of my own timeline as a reference, but I can't rely on them completely… The hidden Ōtsutsuki are troublesome—Isshiki, the Sage of Six Paths, and Ōtsutsuki Hamura. In a world without Kazuki, their stances are uncertain."
"So-called divinity makes them stand aloof. Before there is power to speak as equals, I must tread with extreme caution."
Tobirama established his action plan for this alternate time-space, his thoughts and logic sharpening.
"Now… who should I choose as my bonded partner? According to Kazuki, I must find someone whose emotions I can stir, someone whose strength and compatibility align with mine…"
He frowned slightly, narrowing his eyes as a candidate came to mind. "Uchiha Madara?"
But almost at once, Tobirama shook his head.
His original plan was to ignore the blind date entirely and devote himself solely to finding the Shibai Remains of this world.
Yet when he thought further…
When bringing back the Shibai Remains, he would need a native individual whose mind was linked with his, to conceal the aura together.
Uchiha Madara, bound with him in such a way? Even with Tobirama's imagination, he couldn't picture that scene.
Senju Tobirama let out a sigh, yet the fighting spirit in his eyes only grew stronger.
As expected, this was no simple task… and precisely because of that, Kazuki had entrusted him with it!
"First, I need to get a grasp of the current situation. This is going to be a relatively long-term mission…"
Tobirama steadied his breathing, then slowly stepped into the bedroom of the young Hashirama, carefully observing his surroundings.
Black mourning robes.
"This is…" Tobirama's heart stirred, and he immediately understood.
The only one who could put Senju Hashirama in mourning was their father—Senju Butsuma!
Tobirama slowly picked up the documents scattered across Hashirama's desk and began to read.
[Five days ago, a large-scale battle broke out between the Senju clan and the Uchiha clan. In it, the two clan heads—Senju Butsuma and Uchiha Tajima—clashed directly, and in the end, both perished…]
[In order to retrieve the corpses of their respective leaders, members of both clans fought a fierce and bloody struggle, before eventually retreating.]
[In this battle, the Senju clan lost 172 troops, while the Uchiha clan is estimated to have suffered around 200 casualties.]
[…]
The remainder of the records detailed the reactions of other shinobi clans after this titanic clash between the two giants.
"So, the same as in my original time-space… those two old men still died by each other's blades?"
Tobirama narrowed his eyes, a thought surfacing.
In his own timeline, it was right after this very battle that Uchiha Madara and Uchiha Izuna awakened the Mangekyō Sharingan!
That power—so much stronger than the three-tomoe Sharingan—had once driven Hashirama and Tobirama to utter despair, plunging them into a dire disadvantage.
The reason they had been able to turn the tide was because Hashirama's growth had been too astonishing—perfecting his Wood Release in a short span, mastering Sage Mode, and even forging an alliance through marriage with the Uzumaki clan, thereby gaining a massive influx of reinforcements.
Had Hashirama not risen to the occasion—
By the time Tobirama invented the Flying Thunder God to counter Uchiha Izuna, he doubted whether he could have endured.
The Uchiha clan's leap in strength from the three-tomoe Sharingan to the Mangekyō Sharingan was simply overwhelming—if not for Hashirama being even more overwhelming, able to suppress Uchiha Madara by force, who could have said which side would have prevailed?
"Who exactly should I choose as my bonded partner? The rules of this alternate time-space… truly troublesome."
Senju Tobirama glanced at the list of his sealed abilities, his eyes landing on the Flying Thunder God Technique.
Since arriving in this time-space, his perception of spatial fluctuations had dulled. As a result, even techniques he should theoretically still be able to use—like the Flying Thunder God—could no longer be performed smoothly.
Such was the crushing suppression of spacetime against intruders. Even someone as strong as Rinnegan Sasuke in the original timeline could only brawl in other dimensions like some genin, trading elbow strikes and grapples with the Ōtsutsuki.
"Eh? You're awake, Tobirama…"
The young Hashirama slowly stirred, turning his gaze toward his younger brother, who stood deep in thought by the desk. He scratched his head. "I… I'm about to become clan head, Tobirama… Honestly, I don't think I'm suited for this role at all."
"No need to say more, Brother. You just focus on fighting."
Tobirama replied smoothly, as if by habit: "You must train harder! With Uchiha Tajima's death, there's a chance the Uchiha siblings, Madara and Izuna, might awaken the Mangekyō Sharingan. That would put us at a severe disadvantage!"
The young Hashirama nodded, though confusion flickered across his face.
Did Tobirama misspeak just now? Why did he say "Uchiha siblings, Madara and Izuna"?
Wasn't it "Uchiha siblings, Madara and his sister"—the one hailed as the strongest kunoichi in Uchiha history, Uchiha Izunai?
Hashirama mulled it over for a moment. Perhaps, in Tobirama's eyes—who had always treated her as a rival—she was no different from a man…
Put that way, it wasn't entirely wrong.
"Tobirama, must we really fight the Uchiha clan? Maybe… maybe we could try to speak with them first," Hashirama asked cautiously.
He was already prepared to be scolded.
After all, Tobirama was a hardline advocate of war, never once considering peace talks with the Uchiha.
Yet, to Hashirama's surprise—
"Very well. Let's meet with them and talk."
But in Tobirama's heart—
He had no intention of negotiating peace. What he truly wanted was to confirm with his own eyes the state of Uchiha Madara and Uchiha Izuna in this timeline, and then decide his next move.
What Tobirama never expected was—
The one he was about to meet would not be Uchiha Izuna.
But rather the one Kazuki had prepared for him—
Uchiha Izunai!
