Slowly but steadily, a certain wheel materialized from the Void Realm.
The material was plastic.
The color was white.
The style was a backrest chair.
In an instant, a white plastic chair fitting the current scene appeared before the puppet face, landing steadily on the ground.
The Mahito sat on the white plastic chair, a pair of sunglasses somehow appearing in his hand.
He put on the sunglasses and lay back in the chair.
The metal disc emitted a slightly trembling metallic sound.
"Is this the Construction Technique?"
"But I heard your Cursed Technique isn't the Construction Technique, but healing."
No, to be precise—the evolution of the Soul.
"I had anticipated your abilities might be more comprehensive, perhaps covering the entire Soul Domain, but I never expected you to be able to use abilities outside the Soul Domain."
"Do you possess multiple Cursed Techniques?"
"In history, besides Ryomen Sukuna, there actually exists another being capable of using dual techniques?!"
The Mahito was somewhat surprised.
He slightly lowered his sunglasses, looking at the metal disc with half an eye, and asked with interest.
"Very few people know that Ryomen Sukuna possesses two different Cursed Techniques."
"When I flipped through the biographies of famous figures in the Jujutsu world, there were no records."
"If not for Teacher's teachings, I would have thought this world simply had no one capable of using more than one Cursed Technique."
"But you know."
"This shouldn't be a matter of study."
"You specifically sought out and inquired."
"Why are you interested in Ryomen Sukuna?"
The metal disc didn't answer immediately but asked: "One question, one answer?"
One question, one answer is indeed the best way for both sides to understand each other.
The Mahito didn't refuse; he nodded in affirmation.
"One question, one answer."
Kenjaku clapped his hands, adding terms.
"When unable or unwilling to answer, remain silent."
"When guessing or speculating, must state so in advance."
"Cannot give vague answers or use leading rhetoric."
Kokichi said: "Binding Vow?"
The Mahito responded: "Binding Vow."
"Ending with 'the final confirmation from both sides that the Q&A is concluded' constitutes the Binding Vow," Kenjaku said.
As soon as the words fell, both Kokichi and the Mahito clearly felt the Binding Vow.
The Binding Vow was established!
Kinji Hakari witnessed the establishment of this Binding Vow and couldn't help but twitch his eyebrows.
"You guys, what do you take a Binding Vow for? An unbreakable contract?"
"Don't look down on the 'Binding Vow'!"
"Throughout history, how many Binding Vow masters died in bizarre places because they failed to accurately grasp the direction of the vow?"
"Even now, there are many mysteries about Binding Vows waiting to be unraveled."
"Anyone in the Jujutsu world with a bit of common sense should know that using Binding Vows as little as possible is the most correct way to treat them."
Kinji Hakari was correct.
Binding Vows are extremely dangerous techniques for Sorcerers.
Even in the original work, the appearance of Binding Vows was extremely rare.
Kenjaku is the most famous representative of utilizing Binding Vows.
Over the millennia, he has established many Binding Vows, with very few backlashes.
If made public, it would undoubtedly cause an academic earthquake in the Jujutsu world.
His secret to utilizing Binding Vows boils down to just one—
"Sincerity."
Kenjaku raised a finger.
"Binding Vows are terrifying things, but if you delve deeper, you'll find that what's terrifying isn't the Binding Vow itself, but the two parties involved."
"Ultimately, self-imposed vows differ from vows with others."
"If you break a self-imposed vow, you only lose the power gained from it."
"But if you violate a vow with others, heaven knows in what way the price will be collected."
Kinji Hakari was speechless.
"You understand this perfectly well."
"This is because when both parties establish a Binding Vow, one side harbors ill intentions, leading to the price."
Kenjaku retracted his finger, placed both hands into his wide sleeves, and said with a smile.
"If both parties are wholeheartedly committed to the Binding Vow, then the vow is merely a reminder—those historical Binding Vow masters you mentioned who suffered backlash did so because they arrogantly believed their wordplay would be accepted and utilized by the vow as normal."
"They lost their reverence and sincerity towards both parties of the vow and reaped what they sowed."
There is such a traditional contract, called a Gentlemen's Agreement.
This Gentlemen's Agreement has no written certification, no witnesses, and doesn't even require any cost.
It is considered that 'both gentlemen, at the moment the contract is established, absolutely cannot violate it.'
Because when both parties set the contract, they both believe the other won't violate it, and they firmly believe they themselves won't violate it.
Using their own credibility as proof, both parties affirm the contract's establishment.
"The 'Binding Vow' is a 'Gentlemen's Agreement'."
As long as both parties bound by the contract have the heart to fulfill it, act accordingly, and don't play any tricks or word games within it, then the 'Binding Vow' won't have any cost.
This is the optimal aspect of the Binding Vow, and also the fundamental reason why Kenjaku has never suffered backlash from a Binding Vow over millennia.
Sincerity is the optimal solution for dealing with the 'Binding Vow'.
Just like the current 'Binding Vow'.
Both Kokichi and the Mahito sincerely hoped to use this question-and-answer format to deepen their understanding of each other, and they were internally certain not to use leading language or obscure facts during this exchange.
They needed a trustworthy Gentleman's Agreement to complete their mutual recognition and probing.
Thus, the positions and intentions of both parties were highly consistent.
This was the most perfect Binding Vow, a "Binding Vow" without any cost.
What Kenjaku said served as both supplementary explanation and a threat.
Only when both parties were "sincere" would the Binding Vow be perfect.
If either party harbored ulterior motives, the Binding Vow would inflict unknown damage on both.
There was no need to elaborate on the Mahito's side; the problematic party could only be the other.
Kokichi understood the warning.
The mouth of his puppet face opened, emitting a metallic sound.
"Strictly speaking, I am the one asking for help. Of course, I will abide by the Binding Vow."
The Mahito nodded gently.
"To show sincerity, Kokichi-san, you may ask the first question."
Clap.
The Mahito snapped his fingers again.
Next to the white plastic table, four high-backed chairs reappeared.
Jogo and Hanami naturally took two of the high-backed chairs.
Kinji Hakari hesitated before taking one of the remaining seats.
Only after Kinji Hakari sat down did Hoshikira Roro take the last one.
At this point, everyone on the Mahito's side, except for Dagon who was still playing in the deep sea, was seated.
They regarded the Mahito as the spokesperson, and the full power of the King of Spirits faction was displayed before Kokichi, causing a sudden pressure in his heart.
Special Grade Cursed User Geto Suguru.
Intelligent Special Grade Cursed Spirits Jogo, Hanami, and Dagon.
The Uncrowned Special Grade Jujutsu Sorcerer Kinji Hakari.
The rare Space Sorcerer Hoshikira Roro.
And—
The King of Curses, the Mahito.
It was no exaggeration to say that no person or force in the entire Jujutsu world, besides Gojo Satoru, could withstand this lineup.
Kokichi secretly took a breath and began the formal question-and-answer session.
"Then I will get straight to the point."
The metal disk puppet emitted a solemn metallic sound.
He neither asked about curing his own Heavenly Restriction nor about prohibiting attacks on his companions, nor did he ask the previously intended question about "Dual Cursed Technique."
He asked: "King of Curses, what is your objective?"
