Tokyo Jujutsu High, Principal's Office.
The sunlight streaming through the window did nothing to dispel the stifling air of death that filled the room.
Masamichi Yaga sat in his broad office chair, clutching a photograph so tightly it had begun to wrinkle.
In the photo, four young people stood together on a beach in Okinawa.
Satoru Gojo was laughing arrogantly, trying to dunk Suguru Geto into the water; though Geto looked annoyed, a faint smile played at the corners of his mouth. Shoko Ieiri stood by, watching the scene with a cigarette, while the youth named Yoru stood quietly to the side, clutching a pitch-black blade with a gentle gaze.
That was the peak of their youth.
It was also the moment Masamichi Yaga had been most proud of as their homeroom teacher.
But now, it was all ruined.
*Drip.*
A single, murky tear fell onto the photograph, landing right on Geto's gentle face.
In just a few days, Masamichi Yaga seemed to have aged ten years.
His once-stern face was etched with deep exhaustion, but the most jarring sight was his hair—what had been short and black was now entirely white.
He had aged a lifetime in a single night.
As the principal, he bore the crushing weight of the General Headquarters; as a teacher, he suffered a heartbreak beyond imagination.
His three most prized students.
One was now a heinous traitor with blood-stained hands, another had grown even more arrogant and overbearing, and the last acted mysteriously every day, his true intentions unknown.
*Thud!*
Yaga slammed his fist onto the desk, the force knocking a needle-felt Cursed Corpse onto the floor.
"Geto... just why... why did you do this?!"
He buried his face in his hands, his voice rasping with agony.
Just then, the office door was pushed open.
Yoru, dressed in a clean Jujutsu High uniform with his signature Shiranui hanging from his waist, stepped slowly inside.
He looked at the aged Yaga, a flash of pity crossing his eyes.
However, he knew that for the sake of the greater plan, he couldn't reveal the full truth to Yaga just yet.
While Yaga was a good teacher, he was ultimately a man of the system; if he knew too much, it might alert the higher-ups or Kenjaku.
"Principal Yaga."
Yoru walked to the desk, picked up the fallen Cursed Corpse, and gently set it back down.
Masamichi Yaga looked up, his bloodshot eyes fixing on Yoru.
"Yoru... you're here."
Yaga took a deep breath, forcing himself to remain calm.
"The higher-ups are pressuring us again. They want us to cooperate immediately in the mission to execute Suguru Geto."
"And then there's Satoru. Because he let Geto go in Shinjuku, they're even starting to suspect he's an accomplice."
"This school... I don't know if it can hold on much longer."
Hearing Yaga's near-desperate tone, Yoru shook his head slightly.
He pulled out a chair and sat across from the principal.
"Principal, don't worry about those old dogs barking at the General Headquarters. As long as Satoru is here, they won't dare make a real move against the school."
Yoru's voice was calm, yet it carried a stabilizing weight.
He looked Yaga straight in the eye, pausing for a moment before speaking in a slow, solemn tone.
"As for Geto's situation..."
"Principal, the world isn't just black and white."
Yaga froze, a look of bewilderment flashing across his face.
"What do you mean?"
Yoru leaned in slightly and lowered his voice.
"Geto... has his reasons."
"There are some paths that must be walked, and some darkness that must be carried."
"All you need to know is that he never betrayed our original oath."
*Boom!*
Yoru's words hit Yaga like a bolt of lightning, exploding in his mind!
He stood up abruptly, staring intently into Yoru's eyes as if searching for even the slightest hint of a lie.
There was none.
Yoru's gaze was as pure and firm as the blade at his side, leaving no room for doubt.
Yaga was an experienced sorcerer who had weathered countless storms.
After the initial shock, his mind—which had been clouded by grief—began to cool and sharpen.
He recalled everything that had happened over the past few days.
Geto's sudden descent into madness, Satoru's unusual behavior on the streets of Shinjuku, and now Yoru's cryptic hints...
A vast, invisible web seemed to be unfolding before his eyes.
"So... is that how it is..."
Yaga slumped back into his chair, letting out a long breath.
He didn't press for more details.
He knew that with some secrets, the less known, the safer one was.
Since his three strongest students had made their choice, all he could do as their teacher was protect their home base!
"I understand."
Yaga looked at Yoru, the old authority and resilience returning to his bloodshot eyes.
"I will handle the pressure from the higher-ups."
"But remember—no matter what happens, Jujutsu High will always be your home!"
After leaving the office, Yoru headed straight for the underground training grounds.
Geto's departure wasn't just a blow to Yaga; for the first and second-year students, it was a devastating psychological earthquake.
This was especially true for Kento Nanami and Yu Haibara.
*BOOM!*
A deafening roar echoed through the underground training grounds.
Drenched in sweat, Kento Nanami swung his blunt blade with bloodshot eyes, frantically attacking a Special Grade test target.
He wasn't using any technique; he was simply venting his rage and powerlessness.
Why?
Why did Geto-senpai, who was always so kind, turn into a murderer? Why had he survived, only to be unable to change anything?!
"Nanami! That's enough! Stop!"
Yu Haibara shouted anxiously from the side. He tried to rush forward to stop him, but was blown back by Nanami's wild Cursed Energy.
Just as Nanami was about to collapse from exhaustion...
A slender yet powerful hand firmly gripped his chaotic, blunt blade.
Without using a shred of Cursed Energy, Yoru stopped an attack strong enough to shatter stone using nothing but pure physical strength.
"Instructor Yoru!"
Haibara cried out in relief at the sight of him.
Panting heavily, Nanami looked up at Yoru, his eyes filled with confusion and pain.
"Instructor Yoru... what are we supposed to do?"
Nanami's voice trembled slightly.
"Did Geto-senpai... really become one of those monsters?"
Looking at the two boys whose fates were so tragic in the original timeline, Yoru sighed inwardly.
He released his grip, letting Nanami's blade fall to the ground.
Then, he stepped in front of them, his gaze piercing.
"Nanami. Haibara."
Yoru's voice wasn't loud, but it carried a weight that reached their souls.
"Do you really think Geto is the kind of maniac who would slaughter innocents just because he hates 'monkeys'?"
Both of them froze.
They remembered how much Geto had cared for them, and how he had protected them in past missions even when he was heavily injured.
"No... that's absolutely impossible!"
Haibara shouted, tears finally spilling over.
Nanami grit his teeth. He didn't speak, but the fog of confusion in his eyes began to clear.
"Then believe in him."
Yoru patted their shoulders, his tone resolute.
"Geto hasn't changed."
"He is simply on an incredibly dangerous secret mission that only he can complete."
"He left the world of light to you, and stepped into the darkness himself."
Hearing Yoru's words, Nanami and Haibara's eyes widened in shock.
A secret mission?!
"So, pack away your tears and your weakness."
Yoru turned around, leaving them with the image of a back as immovable as a mountain.
"What you should be doing right now isn't venting like a bunch of losers."
"It's training your asses off to get stronger!"
"Get strong enough to survive the war to come. Get strong enough to be his support!"
"Wait for the day he returns in triumph!"
*Boom!*
Yoru's words were like a strike of thunder in the dark, completely clearing the gloom in their hearts!
The two looked up, the light returning to their eyes as a fierce fire began to burn.
"I understand, Instructor Yoru."
Nanami picked up his blade and adjusted his glasses.
His face, already somewhat mature for his age, now held a cold, resolute maturity that was almost chilling.
"I'll become stronger than anyone—strong enough to personally punch Geto-senpai awake!"
Seeing them rally, Yoru nodded in satisfaction.
Under Yoru's reassurance, the group at Jujutsu High didn't fall into despair or fracture like they did in the original story, despite their grief.
Instead, they channeled that pain into an absolute drive to grow stronger!
However, Geto's departure had still left a massive void in the school's top-tier combat power.
Faced with the impending upheaval that Kenjaku and Sukuna would bring, their current strength was far from enough.
Yoru looked toward the direction of Kyoto, his gaze deep.
"It's time to go and get that little one out of her prison."
As the ripples of Geto's defection began to settle, what kind of storm would Yoru's next move stir up?
And how would that girl in Kyoto, suffering through her torment, break the chains of a thousand-year destiny under his guidance?
