"(So the world is sealing these monsters behind the Warp and siphoning their strength through the balance between Sorcerers and Cursed Spirits…)"
"(But this is way too inefficient! It would take hundreds of millions of years to weaken even one of them, and it's still incredibly difficult to win!)"
"(There has to be a way out of this! If time and space are meaningless in the Warp, then my future self must have left a solution here!)"
The Six Gods inside the Warp made Rutosa feel a true sense of crisis for the first time.
At first, he hadn't thought much about Cursed Spirits in this world because he had already maximized his survival abilities.
Not to mention that in the future there would be Itadori Yuji as the protagonist and Gojo Satoru as a side character(strikethrough)—the strongest sorcerer.
Rutosa had seen the famous meme of Gojo Satoru being sliced in half by Dismantle.
But so what? Wasn't there Itadori Yuji?
Even if Sukuna was so strong that she could destroy the Earth by herself, her ending should still be defeat at the hands of Itadori Yuji in some way.
As someone with common sense who hadn't even watched Jujutsu Kaisen before, Rutosa assumed Sukuna's fate wouldn't be much different from villains in other stories—she would definitely end up being defeated by Itadori Yuji.
That was how Rutosa had thought when he was first reincarnated into this world.
Knowing this "ending," he had worked hard to master Black Flash purely to maximize his survivability and live long enough to see Sukuna killed by Yuji.
But… from the scenes he had just witnessed and the prophetic dream before, it was clear he definitely wouldn't live long enough to reach that day.
His connection with the Warp had deepened more and more. The current link was already so strong that Rutosa couldn't sever it even if he wanted to.
At this rate, he could say with 10 billion percent certainty that these Six Gods would climb the "internet cable" and beat him to death within a decade or so—just as the previous dream had prophesied.
He hadn't taken that dream seriously before because he hadn't thought much of it. Now, after seeing these scenes, he was certain they represented inevitabilities left behind by his future self.
So if these were messages from his future self… there had to be a way out… a solution he had left for himself.
Rutosa swam and swam, fighting against the torrent of cursed energy and its relentless waves.
Then he saw it.
He saw the message left by his future self.
Rutosa froze for a few seconds before bursting into laughter.
"Bastard. If you can't beat them, just join them, right?"
It was the classic trope used by so many authors. Hate ghouls? Become a ghoul and fight them. Hate titans? Become a titan and destroy the world.
This time, all he had to do was become the vessel for the Great Descent of the Sixth Great Power—the Final Trial of Humanity.
As long as he became their ally, wouldn't that cancel the aggro? Problem solved.
Satoru glanced at Rutosa, who sat at the head of the table with a faint smile on his face. For some reason, she felt that Rutosa had changed since he woke up.
How to describe it… his eyes had become much deeper, calmer, redder—and carried a faint touch of divinity?
These changes were unnoticeable to normal people's naked eyes, but they were glaringly obvious through her Six Eyes.
"What are you thinking about?"
Satoru asked.
Rutosa raised an eyebrow at her question, then suddenly realized she had probably noticed something different about him.
"Nothing. I was just thinking about going to the beach and saying something like 'eliminate everything on the other side of the ocean to gain freedom.'"
"What a strange thing to say. Why would eliminating everything on the other side of the ocean give you freedom? Isn't the ocean itself what separates them?"
"Who knows? Sometimes the distance between things isn't as far as the distance between human hearts."
"By the way, Satoru, do you want to continue your Sorcerer training?"
Satoru paused for a brief moment.
"Sure. When do we start?"
"Oh?"
Rutosa was a little surprised. He had thought she would be addicted to the comfort and want nothing more to do with the Jujutsu World.
"What's with that look? Did you think I'd stay away from the Jujutsu World forever? Not to mention my Six Eyes—my head already has a multi-million-yen bounty on it. With that kind of temptation, if I don't improve my strength soon, I'll just be a fish on the cutting board for them."
"That's true. It was my oversight to think someone like you would act like a typical four-year-old."
"You're the same age as me!"
Well, it couldn't be helped. Although Rutosa was the same physical age as Satoru, he was reincarnated while she had been newly born.
Rutosa had prepared himself for her to whine and throw a tantrum about training, but he hadn't expected her to agree so easily. As expected of Satoru—even as a child, she was still the strongest.
After finishing the meal, Rutosa led Satoru to his usual training room.
"Since you've already mastered Neutral Limitless and Blue, and you won't be learning Reverse Cursed Technique anytime soon, let's go back to the basics."
"What I'm going to teach you is something I've summarized from my own experience: the basic usage of cursed energy. I call them the Four Major Principles."
Drawing from knowledge of his previous life, he copied and adapted the concepts from Hunter × Hunter.
"The Four Major Principles are: Shroud, Suppress, Enhance, and Release."
Rutosa shifted his posture.
"Shroud is the principle of enveloping and containing. It's the act of controlling and circulating cursed energy without letting it leak. Shroud provides extra protection and increases your sensitivity—anything that touches your cursed energy will alert you."
Cursed energy surged from within Rutosa's body and enveloped every part of him like a second skin.
Through Satoru's Six Eyes, she could see the smooth, flowing cursed energy moving like a gentle stream across his body.
"Suppress is the principle of stillness and restraint. It's the act of stopping the movement of cursed energy and suppressing it deep within yourself. This principle offers concealment, better mood regulation, allows natural positive energy to flow through the body, and improves self-control. Its drawback is obvious: you leave yourself unprotected against external cursed energy."
The shrouding cursed energy retracted and stilled, losing all motion.
For a moment, Satoru's Six Eyes lost track of Rutosa—his cursed energy signature had completely vanished from her perception.
"Enhance is the principle of focus and bestowal. Imagine your cursed energy surging out at a single point like a high-pressure water jet—that's Enhance. It can be seen as the offensive counterpart to Shroud. Since cursed energy is born from negative emotions, you can attach specific emotions to Enhance and project that emotion onto your target."
Rutosa threw a punch toward Satoru. The wind from the strike brushed her bangs, but what came with it was pure malice carried on the cursed energy.
The cursed energy itself did no physical harm, but the sudden flood of negative emotion made the cursed energy inside Satoru's body go out of control. It reacted chaotically, spiking, becoming erratic in response to the pure malice.
"Release is the principle of dispersion and expression. You disperse your cursed energy into the surroundings without the focused intensity of Enhance—just letting it spread widely from your body. Unlike Enhance, where you can only attach emotions, Release allows you to express your own personal qualities through your cursed energy, because each person's cursed energy is unique—shaped by their Innate Technique, mindset, and physique. While it lacks Enhance's explosiveness, in exchange you gain a profound calmness that lets you look inward and see your own soul. It is also the foundation for forming Simple Domain and, later, Domain Expansion."
The cursed energy dispersed from Rutosa's body like a fine mist, enveloping the area around him.
The moment she saw it, Satoru's Six Eyes widened. She could feel it—the uniqueness within Rutosa's cursed energy.
It was the infinity. It was the primal fear. It was the world itself. It carried a touch of divinity. It was all things—experiences, history, thoughts, feelings—that made him who he was.
Before Satoru could recover from her shock, Rutosa had already recovered all the cursed energy back into his body.
"As long as you master these Four Major Principles, you can stand on your own in this Jujutsu Kaisen."
