Kenjaku's body was almost swallowed by the black lightning. A Black Flash barrage of such high frequency had never been seen in the history of the entire Jujutsu World.
Although Black Flash is theoretically impossible for anyone to release actively, continuous release is not impossible. After landing the first Black Flash, a Jujutsu Sorcerer's state is greatly improved, making the second and third Black Flash no longer a fantasy.
Chinatsu and Gojo Satoru were both immersed in a state of concentration that shocked even themselves. Everything besides triggering Black Flash was meaningless; only the black lightning blooming from their fists consumed their entire being.
"Black Flash!!!"
The two attacked from the left and right simultaneously, delivering a Black Flash barrage. The threads connecting Kenjaku's head to the hundred million people visibly shook, appearing precarious.
However, less than 60 seconds remained until Kenjaku's complete assimilation with the hundred million people was complete. Sensing this progress, she, whose consciousness was already hard to definitively identify as Kenjaku's, continued to laugh maniacally with her head raised, even while enduring the combined double attack from Chinatsu and Gojo Satoru.
Time... favored Kenjaku!
As time passed second by second, the frequency of Chinatsu and Gojo Satoru's Black Flash strikes also decreased, but both could feel that they were truly just a little bit short.
"Damn it!"
Gojo Satoru landed a forceful punch on Kenjaku's body. His punch did not produce a Black Flash, and at this moment, the final 10-second countdown until Kenjaku's assimilation was complete had begun.
10 seconds.
9 seconds.
8 seconds.
7 seconds.
6 seconds.
5 seconds.
4 seconds.
3 seconds.
2 seconds.
1 second.
Kenjaku's laughter grew increasingly shrill. Gojo Satoru successfully landed one more Black Flash in the last second, but it was still just that tiny bit short.
Were they going to... lose?
No, they wouldn't.
This situation absolutely would not happen!
Gojo Satoru, sweat streaming down his cheeks, turned his head to look at his Older Sister beside him. He saw that Chinatsu had, at some unknown point, withdrawn her punching stance and instead raised her hand, forming a special hand sign.
Domain Expansion?
It didn't look like it. But if Domain Expansion, the ultimate secret of Jujutsu, couldn't save them, what else could she use at this moment?
Wait, could it be... Before a second had passed, Gojo Satoru understood what move his Older Sister was preparing to use, and simultaneously, he sighed helplessly in his heart.
"As expected, I can't compare to Older Sister."
Thinking this, the tightly strung nerves of Gojo Satoru immediately relaxed. Simultaneously, Chinatsu's words followed.
"Maximum Technique: Naghi."
Instantly, the shrill laughter emanating from Kenjaku's mouth abruptly ceased. The sound of explosions caused by Cursed Energy clashes vanished. The entire world fell silent, quiet as a colorless, black-and-white picture.
What is Limitless?
The essence of Limitless is the ability to manipulate surrounding space-time through the atomic-level Cursed Energy manipulation precision granted by the Rikugan.
What is Maximum Technique?
If Domain Expansion is the ultimate secret of Cursed Techniques, then Maximum Technique is the extreme limit that a single Cursed Technique can achieve.
For example, the Cursed Spirit Jogo's Maximum Technique is called [Meteor], which can summon a giant molten meteorite. Geto Suguru's [Uzumaki] allows him to sacrifice the Cursed Spirits he holds as fuel to unleash a world-shattering blast.
Ever since Chinatsu mastered Domain Expansion, she had been continuously researching this extreme limit within the Limitless Cursed Technique, which was inherited from Sugawara no Michizane in ancient times.
However, trying to find the "extreme limit" within "Limitless" was truly too complex. For a time, it made Chinatsu feel as if she were trying to prove that 1 + 1 could equal 3—utterly absurd.
Nevertheless, Chinatsu did not give up.
Relying only on "Mirror Flower, Water Moon" as a trump card was not enough. Unforeseen situations were bound to occur in the future, and attempting an on-the-spot breakthrough then would be too reckless. Preparing in advance suited Chinatsu's personality.
Of course, there was a significant element of risk involved.
Over the years, Chinatsu had only managed to grasp the general concept. Although she had succeeded before, the result was almost the same as failure. Otherwise, she would have used it when fighting Sukuna, instead of hiding it until now.
Limitless, the power of stillness.
Lapse Blue, the power of attraction.
Reversal Red, the power of repulsion.
When the powers of attraction and repulsion combine and clash, the power known as Hollow Purple is generated. This is a fictitious mass that should not exist, capable of annihilating other matter.
And when the basic Limitless Defense is isolated, expanded, and specialized, the power of stillness completely covers the surrounding space-time.
This was Chinatsu's Maximum Technique!
At this moment, Chinatsu was situated in a space-time where only she could move. She herself was unsure how long this could be maintained; in her attempts, the worst record only lasted 0.1 seconds.
Chinatsu took a deep breath and clenched her fist. The brief moment she had managed to seize was her last chance; she absolutely could not fail.
Clear, bright blue Cursed Energy gathered on her fist. In the instant Chinatsu abandoned everything and concentrated on this single punch, although she hadn't struck yet, Chinatsu seemed to see the future where she landed a Black Flash.
"Black Flash!!!"
Chinatsu landed a solid punch squarely on Kenjaku's surface, and brilliant black lightning fiercely bloomed.
In terms of raw power, this strike absolutely couldn't compare to the Black Flash she delivered at her peak, but this final Black Flash was like the last straw that broke the camel's back.
Time began to flow again.
Chinatsu, feeling somewhat exhausted, descended from mid-air onto the ground. As the extreme limit of a Cursed Technique, and one with such an abnormal effect, the Maximum Technique's consumption, both mental and physical, was enormous.
However, it was worth it.
Gojo Satoru quickly rushed to Chinatsu's side and asked about her physical condition. Chinatsu simply waved her hand quietly, indicating that she was fine.
She raised her head and looked at Kenjaku floating in mid-air. Starting from a body like a god or Buddha, then transitioning to the grotesque silhouette of a demon, she now struggled to maintain even a human form, floating in the air as an ugly, unidentifiable mass.
Most importantly, the black threads connecting her head to the hundred million people were already broken. Even if the data transmission progress reached 99.9%, as long as it didn't reach 100%, it was unequivocally a transmission failure.
"Kenjaku, we won."
Chinatsu and Gojo Satoru stood on the ground, looking at Kenjaku, who was about to completely collapse from existence, declaring their final victory.
Unexpectedly, facing the collapse of her existence, Kenjaku merely transitioned from one type of madness to a new one. While continuously collapsing, she stretched out one of her fingers toward Chinatsu, opening her lips with a ferocious expression.
"Chinatsu, I curse you..."
