Gojo Satoru suddenly asked.
Todo Aoi, already used to his personality, said flatly, "Human negative emotions."
"Bingo~!"
Gojo Satoru gave a thumbs up and continued, "Born from human negative emotions, they can never be friendly to humans by nature. Human negative emotions are like their food, which is why they kill people."
With that, Gojo pointed at the stigma on Amber's chest. "With such a massive amount of Cursed Energy, it's not the kind of existence that enjoys playing house games. Do you understand now?"
Amber understood, of course, but the problem was that Black Amber wasn't like that at all...
Well, she couldn't deny that Black Amber, having a component of Lahmu, was overflowing with negative emotions, but she also wasn't as dangerous as Gojo described, nor did she harbor any murderous intent toward humans.
In essence, Lahmu's murderous intent wasn't directed at humans specifically, but at all living beings. In other words, Lahmu hated all life equally. Black Amber could suppress this instinct, so naturally, she wouldn't do anything dangerous.
One of the traits of intelligent life is the ability to defy instinct, and Black Amber was no exception.
But she couldn't say any of this, so Amber could only defend her other self: "My other self isn't that dangerous... She just wants to protect Shier..."
Maki Zenin and Todo Aoi heard this and looked at Amber with complicated expressions, feeling that she was being influenced by the curse on her body. It wasn't unusual for curses to lie to survive—the stronger the curse, the smarter it was.
But Gojo Satoru saw through some of it.
His Six Eyes gave him insight beyond ordinary people, and with all his attention focused on Amber, he could see that she spoke without any hesitation. It wasn't a baseless defense; rather, it seemed she had some firm conviction behind it.
"In that case, I'll believe you for now~"
"Really?"
Todo Aoi frowned at Gojo. Even though he trusted everything about Gojo's character, he couldn't help but question this.
Gojo nodded with an unchanged smile. "Since it's a sincere defense from my future student, I'll temporarily trust this curse. But..."
Having made his own arrangements, Gojo didn't give Amber a chance to speak and shifted the topic to the next matter: "Even I can't vouch for something I know nothing about. Little Shier, since you say your other self can be communicated with, let's give it a try."
"Give it a try?"
Gojo's topic jumped quickly, but fortunately, Amber wasn't a slow girl. "Mr. Gojo wants to fight my other self...?"
Her expression showed some reluctance.
The three weren't surprised by her attitude.
From her behavior and manner of speaking, it was clear that this girl was a well-behaved one raised in a warm environment. It was only natural for her to dislike fighting and hurting others.
But what they didn't know was that Amber's reluctance wasn't about hating fighting—it was about being afraid that Black Amber would kill Gojo.
After Black Amber's demonstration for her, Amber had come to understand somewhat what it meant for her technique to be Quantization.
(As for Quantization, just take it as fun. The author is a liberal arts student; I only understand nine out of ten holes in science.)
She could trigger Quantum Entanglement through Quantization. Quantum Entanglement had nothing to do with time or space, and there were no hidden variables. This meant that Limitless, a traditional physics concept, was nonexistent before her. Combined with the unobservable nature of quantum states, it could be considered an advanced version of Obito's Kamui space from Naruto—an ultimate double standard: I can hit you, but you can't hit me.
Because whether she was observed or not didn't depend on her enemy, but on herself.
Amber found it absurd. Even the real Shier wouldn't have this level of power.
She didn't understand quantum mechanics, but she felt this wasn't Quantization at all—it was double-standard-ization.
But soon, Black Amber poured cold water on her.
Black Amber could play like this because she hadn't wasted her years. Lahmu's super learning ability and adaptability had allowed her to acquire a lot of knowledge. If she wanted, she could become a renowned professor immediately.
With Amber's brain... being able to use basic attacks with true damage was already impressive.
This fact frustrated Amber, making her crave the Herrscher of Death and Life's core even more. She didn't want a technique that required brains; she wanted something simple and brutal that worked instantly. If she could draw the core, she could say her technique wasn't Quantization, but Creation and Decay.
Unfortunately, she couldn't draw it.
With everyone lost in their own thoughts, Amber still followed Gojo's lead. The two found a desolate mountain, where Gojo planned to figure out the technique and strength of the curse inside Amber.
Chapter 8: Battle Against the Strongest in Sorcery.
"Do we really have to fight?"
Seeing that Gojo wasn't going to back down, Amber asked one last time: "My other self is really strong..."
She still liked Gojo quite a bit. Even after Gojo became 2.5, she never trash-talked him; she just quietly stopped paying attention. Though even without paying attention, news still flooded her face.
Besides, Gojo's purpose in fighting her now was to confirm her danger level, so he could figure out how to protect her afterward. Clearly, he was on her side. What if Black Amber accidentally killed him later...
Gojo didn't know what Amber was thinking. He just assumed it was a young girl's kindness, not wanting to hurt him, so he smiled confidently: "Don't worry. I'm the strongest."
"...Alright."
Since he said that, Amber could only repeatedly remind Black Amber.
"Oh, by the way, since you said she's controllable."
Suddenly remembering something, Gojo said, "Then switch back to body control in one minute. Consider it part of the test."
After all, if she couldn't even guarantee control over her own body, there was no way to vouch for her in the sorcery world.
"I understand."
Amber nodded. "Should I start?"
"Go ahead~"
Gojo Satoru also adjusted his own state, carefully observing the situation across from him.
The originally thin layer of Cursed Energy covering the girl's body rapidly expanded along with the energy continuously spilling from her chest, and within less than a second, it had already completely surpassed him, the strongest in the Jujutsu world.
"Heh~ Truly terrifying."
Gojo Satoru wasn't surprised by this phenomenon. Looking at Amber, who had closed her eyes, he said in a lighthearted tone, "So then, are you Shier now, or the curse?"
"If those eyes of yours aren't just for show, isn't it obvious?"
The originally reserved girl's voice had now become seductive and eerie. Then she opened those blood-red pupils, and the smile on her face grew increasingly dangerous.
The girl spread her arms out to her sides, her posture arrogant: "If you want to fight, you fight—doesn't that make me look like I have no face?"
"Oh?"
Seeing this, Gojo Satoru made an exaggerated thinking motion, then smiled curiously: "So curses care about that too? Even though you're not even human."
"Hahaha."
These words made Black Amber's already hostile gaze even more ferocious. What she hated most was being treated as an outsider. If she couldn't beat Fu Hua, and if she weren't afraid that Amber would hate her for it, Fu Hua would definitely be her first target for attack.
But now, here was someone rushing to provoke her anger.
"Before we start fighting, let's set a rule."
Black Amber said.
"A rule?"
"That's right. After all, I'm not that coward who's afraid to hurt others. But if I kill you, she might come crying and bother me. So as long as you beg for mercy, I'll stop. That's the rule."
"Haha."
Gojo Satoru laughed too.
This rule was actually quite familiar to him—because he was usually the one setting this rule for others.
"Of course, no problem. And don't worry—as a teacher, I'll make sure to apply just enough force to step on an ant without crushing it. After all, I'm an adult, so I won't bother setting any rules on my end."
Gojo Satoru shot back with a provocation.
"Very well. But I need to warn you of one thing."
Hearing this, Black Amber wore a beaming smile. At first glance, it almost seemed like that shy girl had regained control.
But Gojo Satoru, with his Six Eyes, could tell that her Cursed Energy was already primed and ready. Just as he went on alert, he found that the girl had suddenly vanished from before him.
What was this? The Six Eyes hadn't caught any sign of her disappearance, and there was no trace of Cursed Energy being activated.
Just as he was wondering if she had simply taken over the body and fled, a sense of danger appeared behind him. His instincts, even faster than the Six Eyes, made him dodge—but the speed of her attack still exceeded his imagination. Even reacting instantly, his sleeve was slashed open.
Wait... slashed open? By what method?
Gojo Satoru's heart sank. He couldn't see her technique at all.
"I'm not the same as that coward. If you want to talk to me, you'd better watch your words!"
Standing where Gojo Satoru had just been, Black Amber slowly withdrew the arm that had just swung the scythe, her face full of mockery.
"What was that move just now?"
Gojo Satoru didn't care about the girl's counterattack and instead asked curiously.
"Blabbing your own techniques to others—that's a habit only you Jujutsu Sorcerers have."
Faced with Gojo Satoru's complete disregard for saving face, Black Amber found it utterly boring to taunt him. But driven by her disgust for him, she couldn't help but sneer anyway.
"Oh? Is it because if you say it, it'll be countered?"
Gojo Satoru smiled.
He hadn't felt his technique being broken at all just now. That meant the thing in her hand wasn't a cursed tool that could nullify techniques, and her own technique wasn't the type that countered others'.
Though he said "type," he had never actually seen a technique that countered other techniques.
So what kind of technique could it be? A space-type technique?
"Calling yourself an adult, and still trying to provoke a little girl?"
Black Amber laughed too.
"For little Shier, I am indeed an adult. But for you? Not so sure."
Gojo Satoru skillfully pressed on with his relentless banter.
"Looks like the strongest Jujutsu Sorcerer isn't all that. Fine, I'll tell you... but only if—you survive."
The moment the words fell, Black Amber vanished again. Gojo Satoru's expression immediately turned serious. For the second time, he still hadn't seen the Cursed Energy activation behind her disappearance.
A scythe, composed of varying shades of blue like an ocean, once again swept from behind without warning. This time, prepared, Gojo Satoru moved faster and pointed one hand in the direction of Black Amber's attack.
"Cursed Technique Reversal: Blue."
He didn't use full power. After all, even though she was an Incarnation, this was still his future student's body. Within controllable limits, he didn't want to harm her.
But that didn't mean this strike was weak.
The ground and trees within a dozen meters were instantly twisted by a powerful force of attraction. As that force shot outward, it carved a circular gap dozens of meters wide and hundreds of meters long into the uninhabited mountain in the blink of an eye.
But Gojo Satoru, who had been attacking while also remembering to dodge, was surprised to find that his strikes didn't linger on his opponent for even an instant—they passed straight through as if hitting empty air.
Glancing at his clothes, now mostly torn open, Gojo laughed. "You really are a dangerous one, aren't you? But... isn't it about time?"
Chapter Nine: Cursed Technique.
Quite some time had passed during their conversation, and with two exchanges of blows added in, it was now around fifty-some seconds. In a few more, it would be time to switch back as agreed.
"To survive two of my moves, you're not bad for a toy. Be proud—you've kept your life."
Black Amber naturally understood Gojo's meaning, but her smile remained arrogant. Both of them knew she had been holding back heavily in this fight. If she had attacked relentlessly without giving Gojo time to react or think, his situation would have been far more dangerous.
She wasn't worried that showing too much dangerous power would make Gojo uneasy about her existence and cause trouble for Amber.
After all, this problem didn't have just one solution.
If her power could be suppressed by Gojo, he could confidently place her under his command and vouch for her. But if her power couldn't be suppressed, yet he still restrained himself for Amber's sake, then Gojo could be even more at ease.
A beast that can be restrained but can't be watched at all times, versus a beast that can't be restrained but poses little danger—anyone with a bit of courage should be more relieved they're the latter.
Only cowardly incompetents would prefer the former.
And Gojo Satoru had never been a timid man.
In fact, from Black Amber's very first words, Gojo had already determined that her threat level was extremely low. Possessing immense power yet acting as the girl's protector, even caring about her feelings—it completely overturned his stereotype of curses.
And when the girl's pupils returned to a deep blue, her demeanor shifting back to that shy yet gentle version of herself, Gojo's smile deepened.
"Mr. Gojo... are you alright?"
Amber could see Black Amber's perspective, but even so, she couldn't help asking.
"I'm fine, fine~"
Gojo strode over on his long legs, casually placing a hand on Amber's head and ruffling her hair. "From now on, you'll have to call me 'teacher.' Speaking of which, how old are you now? You don't look old enough for Jujutsu High yet."
