Jujutsu Kaisen: Aspiring to Become an Immortal God

Jujutsu Kaisen: Aspiring to Become an Immortal God Author: Ancient Leaf

Synopsis:

Powerful, invincible, immortal!

Having transmigrated into Mahito, I am about to embark on the path of an immortal god!

Of course, there is a prerequisite—

I must survive first.

1. The Invincible Me Is Born Here

When my hand gently touched the old man who was on the verge of starving to death, I knew my cheat had arrived.

This was the first time since my birth that I had exercised my innate ability. When I gently touched a human with my hand, I could freely alter their soul, and by altering their soul, I could indirectly manipulate their physical body. In just a few seconds, this old man, who had been delirious from hunger, suddenly opened his eyes. They were as bright as a young man's. This was because I had manipulated his soul to make the potential nutrients within his body take effect; at the very least, for this moment, he felt full.

Was this salvation? No, quite the opposite. This was a curse.

I cursed him, giving him a sense of satiety. From this moment on, he would never feel hunger again, but his body's potential had been squandered. In other words, from here on out, he would only maintain that feeling of fullness until he died. It was like a leaking oil tank; what I did was not to replenish the oil inside, but to shrink the tank so that it would seal shut again.

His potential had indeed been consumed by me.

But he survived. He survived through a curse.

I felt no joy in saving a life. On the contrary, I felt an incomparable sense of irritation. I instinctively wanted to reverse this state and plunge the old man I had saved back into the outcome of death. This was a very strange thing. Before I transmigrated, while I wouldn't call myself a saint, I was certainly not a bad person who looked down on humanity. When a dying person lay before me, if I had the ability, I would have been willing to call an ambulance. If I had the power I possess now, I would never have been stingy with my abilities; I would have saved him.

But now, it was the exact opposite. I had indeed saved someone, but the result of saving him was an incomparable sense of irritation. I intuitively realized that this kind of thing went against my instincts, like forcing a tiger to eat grass. A tiger could certainly eat grass, but it could never become a herbivore. This was determined by the tiger's physiological structure; for a tiger, a diet consisting mainly of plants meant only death.

Saving people now didn't pose a threat to my survival; I just felt irritated, uncomfortable, and disgusted from the bottom of my heart, but it didn't create any obstacles to my existence.

However, after this incident, I stopped saving people. I began to harm them.

Of course, I didn't start out intentionally harming people. At the time, I was just observing others while exercising my innate ability because I discovered that I could walk down the street, yet no one could see me. I intentionally touched others, and they did react, which meant I did exist, but I could not be perceived by others. I sometimes suspected I was a ghost, but I quickly judged that I wasn't, because I didn't melt in the sunlight. Of course, depending on the worldview, there are ghosts that can exist during the day, but compared to a ghost, I was more like another kind of existence.

A god. I was very much like a god.

Calling oneself a god is a very embarrassing thing, but through various feedback, I became increasingly convinced that I seemed to be a god.

Before stating my reasons, I must first introduce the world I transmigrated into so that you can step into my shoes. So, let me briefly introduce this world.

This world is almost identical to the one I originally came from. It is also filled with modernization: tall office buildings, pedestrians walking with their heads down looking at their phones, modern clothing, cars, airplanes, and trains are all available. Supermarkets, carts, ramen shops, and various snack shops also exist.

Of course, there is no shortage of entertainment facilities, parks, arcades, and toy stores.

I am not a historian, so I cannot determine what is different here compared to my previous world. Before I transmigrated, I could be considered a shut-in. I could even see various large anime posters plastered on the walls of office buildings; Naruto, One Piece, and Bleach were all clearly visible, and Dragon Ball and Pokémon were also on the list.

Of course, the language spoken here is Japanese, which is also very familiar. Now, let's look at my situation.

I transmigrated into this world. Even though my Japanese ability before transmigrating only allowed me to understand a few simple words, I can now use Japanese without having to learn it. Reading and writing disabilities are completely non-existent. Although there is no one to talk to, I assume there would be no problem with communication barriers.

Because when I talk to myself, I speak Japanese quite fluently. That much is fine.

I cannot be seen by other humans, but I can indeed interfere with others normally. I can touch, change, and even destroy or save—it all depends on a single thought of mine.

I can look directly into a human soul, alter it, make a starving person stay full forever until they die, and of course, I can make a healthy person stay in a state of hunger forever. I can freely change a human soul and, by doing so, achieve a different kind of control over humanity.

I have a feeling that if I can skillfully use my abilities, even granting someone hundreds of years of life, or even immortality, is possible.

Self-taught language and literacy skills, the ability to look directly into and interfere with souls, and the racial trait of being able to unilaterally interfere with others.

From this, I easily concluded that I am a god.

Especially regarding the aspect of controlling humans, I am not just talking nonsense; I have actually tried it.

At the time, I was just thinking about how to exercise my abilities while observing humans, and I suddenly thought of a setting from my previous life. This setting is called a "thought stamp." As the name suggests, a thought stamp can fix a person's thoughts, making them remain fixed in a certain line of thinking no matter how much they think. To some extent, this is the strongest information prison. Usually, an information prison can be broken through by debating with others, coming into contact with other things, and broadening one's horizons, but once a thought stamp is engraved, it can never be escaped. It is more fanatical than fanaticism.

Since I can change a human's body through their soul, I can certainly change a human's thoughts through their soul as well.

Of course, at first, I did have some psychological burden regarding this kind of experiment. I cautiously chose a target. Very luckily, I quickly locked onto one. He was a gambler, and not just a gambler, but a gambler who was also a drug dealer. Such a person deserved to die.

I transformed him openly to practice my abilities. Very unexpectedly, it was very simple to transform him, making him detest gambling and drugs to the point of nausea every time he came into contact with them. He didn't just quit gambling and drugs; he simply couldn't accept them, to the point where he had to stay away.

The principle was also unexpectedly simple. If you have truly understood mentally ill patients, you would know that mental illness is not just a psychological problem; there are indeed physiological issues as well. Some of the more famous depression patients before I transmigrated had functional brain disorders that truly required medication to treat.

Some mental illnesses cannot be managed simply by psychological adjustment; they must be supplemented with medication.

In this respect, as long as you adjust the brain's functions, you can easily create people with mental problems. Just like this piece of human trash who was both a gambler and a drug dealer, by slightly adjusting the structure of his brain, I could make him feel disgusted and nauseated by gambling and drugs, to the point where he would vomit upon contact.

Once he couldn't accept it physiologically, no matter how much his psychology craved it, he would stay away in pain. Humans are creatures that are very good at forming habits. Once this habit became natural, even if he craved gambling and drugs psychologically, he would have to stop the behavior.

Just like that, I spent my days leisurely while experimenting with thought stamps. This day, I also discovered an experimental animal.

He was a high school bully, wearing a school uniform and surrounded by his lackeys. Just like all the stereotypes about bullies, he was in a small alley with his lackeys, kicking someone wearing the same school uniform, a smile full of violence on his face, looking relaxed and content.

I didn't hesitate much before choosing him as my target and gently brushed over his head.

After that, his expression changed from violent to blank, then from blank to ashamed. Finally, in the middle of the bullying, he suddenly pushed his two lackeys away, knelt in front of the victim, and kept kowtowing.

I felt satisfied.

It wasn't just the satisfaction of punishing a bully; it was a feeling of joy from the bottom of my heart. My body and mind felt light.

I realized that it wasn't the morality of my previous life that made me feel light, but rather that I felt light because I had harmed someone through my own hands. In other words, my instincts were reminding me that I was born to harm others. No matter who this person was—a good person, a bad person, a saint, a piece of human trash, or just an ordinary person—they were all within the scope of my "prey."

This is also the reason why I have been so active these days. Although there was no improvement in my abilities, the act of conducting experiments made my body and mind feel happy. The subjects were all insignificant pieces of human trash, and it didn't betray the morality of my previous life, which made me very keen on these kinds of experiments.

I was still summarizing my instincts when, suddenly, the bullied boy I had just saved spoke to me.

He said, "It was you, right? I saw it. You just touched him lightly, and then he turned into that."

I had finished my experiment and naturally chose to leave, but I never expected anyone to actually see me. I had been transmigrated for over a month. For the first week, out of caution, I never left the sewer where I first arrived. Later, however, my courage grew, and I opened the manhole cover to come out. Since then, I had wandered among the crowds, yet no one had ever been able to see me, even though I could freely touch others.

The conclusion that I was a god was also reached during this period.

Because my ability truly possessed god-like potential, and I was firmly convinced of it.

Additionally, I had been influenced by most of the novels and anime from my past life. Although my reason told me I wasn't invincible yet and that I still had other things to encounter and horizons to broaden, I didn't want to be like some "Bone King" and act overly cautious.

Right now, I was wondering if I had transmigrated into some "Tokyo Deity" style novel as the protagonist. I truly believed this, which was why I used my abilities on the street without restraint and why the idea of "thought imprinting" had occurred to me immediately. I was even preparing to recruit a shrine maiden or something similar.

I had already prepared to test my ability to project power through my eyes—like the Sharingan—once I perfected the thought-imprinting ability. I felt I could succeed.

I had assumed that, according to the tropes of such novels, the first person to see me would inevitably be a beautiful girl. I really hadn't expected the first person to see me to be a weak, bullied boy. Still, it was fine; although this boy looked frail, he knew how to show gratitude, so he wasn't entirely useless.

"Excuse me, who are you?" the boy asked cautiously.

I looked at the boy before me. He had black hair with long bangs covering the right side of his face. Because he had just been subjected to violence, he was bruised and battered, looking pitiful, weak, and ridiculous. His school uniform was covered in dust and tattered—a classic image of a victim of bullying. He looked like a total loser.

I thought for a moment and suddenly smiled. "I am a god," I said.

The boy was stunned, not knowing what to say for a moment.

I became interested in him. I looked at him earnestly with eyes that could peer directly into the soul. For the past month, I had been using these eyes to observe others. My vision could even penetrate into human internal organs. In my eyes, the soul was the skin, and the body was the flesh; naturally, every reaction of the body could be reproduced through the soul.

I easily discovered that the flow of his soul seemed indeed different from others, but I couldn't articulate what that difference was. The drawbacks of not having conducted reckless human soul experiments were appearing; my proficiency with human souls was not as high as I had imagined.

If I had known, I would have found more scum to experiment on. Although I had conducted nearly a hundred experiments over the past month, in the beginning, I had cautiously adjusted the details of the thought imprints, doing only one or two a day. Later, as I became proficient, doing five or six a day was a breeze.

I had an intuition that if I continued, I would eventually be able to deeply carve a thought imprint of loyalty to me into a human brain with just a light touch, making it impossible to remove. It wasn't just a matter of ability; it was more of a physical issue. Their brains would be permanently altered by me.

"It's truly unusual that you can see me. You have talent," I said. The boy was stunned again. "Me? Talent?"

"Haven't you noticed? Very few people in this world can see me, and you are one of them."

This statement was not a lie. During this month, I had gone into crowds without restraint, but until now, he was the only one who could see me.

Although it was a boy instead of a girl, which made me feel a tiny bit unhappy, I also felt a slight sense of relief. Before this, I had truly thought I was the protagonist of a novel. Although possessing such a powerful ability meant I was bound to be the protagonist of some "Tokyo Deity" power fantasy, I had no complaints about such a life, but it was better to be unconstrained.

The reason I felt relieved that the first person to see me was a boy rather than a girl was simple: if this were that kind of "Tokyo Deity" power fantasy, and the first person the reader saw the protagonist meet was a boy instead of a girl, it would surely be bombarded with criticism. How could you write a power fantasy like that? It wasn't a shrine maiden!

By the way, if I had seen such a novel before I transmigrated, I would have closed the book without a second thought.

The boy's expression was very strained. "I... am I special?" "You look very reluctant," I asked.

"Because, who would be special in this way?" The boy looked at himself—covered in dust, bruised, weak, and pathetic. If he were gender-swapped into a girl, he might be called "soft and cute," but he was a boy. How could one describe him?

I suddenly asked, "Are you interested in becoming a girl?" The boy was startled. "Huh?"

"If you were a girl, you could be my shrine maiden. A soft, cute girl who cries when bullied—that type of shrine maiden is quite good too," I said.

That's right, I hadn't forgotten about the shrine maiden, and I couldn't forget. I was a god; I had to have a shrine maiden to serve me! How could a god not have a shrine maiden? As a god, I must have one; it's a must!

And my ability allowed me to easily gender-swap a man into a woman. This was much simpler than modifying a brain to create a thought imprint. Although I hadn't actually tested it, I believed it was so simple that it didn't require experimentation.

The boy's expression crumbled. "No, no, no, let's forget about being a girl." "Is that so?" I felt it was a pity.

The boy's face turned pale. "You... you look very serious."

"Because I really think so," I said earnestly. "Believe me, you are more suited to being a girl than a boy. And I truly have the ability to turn you into a girl without side effects. You might even be able to have children in the future..."

"Don't, please don't." The boy's pale face turned white, and he shook his head repeatedly. If a girl had made this gesture, it would have been very cute.

"Oh, really not considering it? I'm very serious," I said.

"It's precisely because you're serious that I'm seriously refusing!" The boy's expression twisted, and even his voice changed from weak and tiny to a near roar. "In the end, why did the topic shift to me becoming a girl? This isn't right!"

"I am a god, after all," I said nonchalantly. "A god naturally needs a shrine maiden by his side. But as you can see, I currently lack one. Unfortunately, to follow me, one must at least be able to see me. For now, you are the only one I've found who can see me, but you are a boy and cannot be a 'shrine maiden.' So I was thinking, wouldn't it be perfect if I just turned you into a girl? Look, it's perfect, right?"

"It's not perfect at all!" the boy shouted in refusal, his face full of grievance.

I couldn't help but smile. Although it sounded a bit perverted, I truly felt pleasure from the prank I had just played (though it might not have been a prank, because if the boy had agreed, I really would have turned him into a her). How strange. Was I this kind of person before I transmigrated? Or was it just like my instinct to refuse to save people and instead harm them—was feeling pleasure from pranks also one of my instincts?

The boy took several deep breaths before he slowly calmed down.

He bowed to me earnestly. "Thank you very much, Lord God."

I waved my hand. "It was no trouble at all." "My name is Junpei Yoshino, I..."

"Wait, what is your name?" I suddenly interrupted him.

The boy—Junpei Yoshino—was startled again, then said in confusion, "Junpei Yoshino. My name is Junpei Yoshino. Is there a problem with my name?"

Of course there was a problem, and it was a huge one.

I observed him carefully: the bangs on the right side covering half his face, the weak expression, the Japanese school uniform. If he hadn't said his name, I definitely wouldn't have had a sense of déjà vu, but the moment he said it, the feeling hit me like a tidal wave, leaving me dizzy.

After a month of transmigrating into this world, I finally knew where I had transmigrated to, and I finally understood what this ability to peer into the soul and change the soul was all about.

No wonder I instinctively refused to save people and instinctively wanted to harm them.

No wonder no one in this world could see me, leading me to think I was a deity. I finally knew who I had transmigrated into.

Damn it, I had transmigrated into Mahito!

I was such a fool, truly. After transmigrating, I always thought of myself as the protagonist of some Tokyo-deity-style story, yet I never considered anything else, to the point that a classic anime like Jujutsu Kaisen had long been cast to the back of my mind.

Mahito felt so ashamed he wanted to dig a hole in the ground with his toes.

But I couldn't be blamed for that. Mahito complained inwardly because, well, he didn't have a stitched-up face at all.

That's right. Although he had confirmed that he was the rather vile villain from the work Jujutsu Kaisen, his appearance was not entirely consistent with the original.

The reason was unknown—perhaps it was a difference in self-perception, though he wasn't certain—but he simply had medium-length white hair and heterochromatic eyes, one blue and one yellow. That was all.

The iconic stitched face simply never appeared, making him look quite different from the original character. Of course, he hadn't realized he was Mahito. Junpei Yoshino asked tremblingly, "Um, Mr. Mahito?"

Mahito had just told Junpei Yoshino his name. It wasn't that he hadn't thought about using another name, or perhaps his name from before he transmigrated, but Mahito eventually abandoned those options. He made up his mind to use the name Mahito. It wasn't that he thought so highly of the name; it was simply because he felt it was more convenient to use. Besides, if he ever encountered some innate technique that used a true name, he could use "Mahito" as a shield. Whether it would actually work or not, it certainly wouldn't hurt.

"Sorry, I was just spacing out for a moment." Mahito let out a breath, setting his embarrassment aside for the time being. "Where was I?"

"Yes, you were talking about the soul," Junpei Yoshino said.

Upon realizing that this person's name was Junpei Yoshino, Mahito sensed it—he hadn't transmigrated into some Tokyo-deity-style world, but into the anime Jujutsu Kaisen. There was no time to continue taking things easy; he had to start considering the future. After all, he clearly remembered that in Jujutsu Kaisen, the special-grade cursed spirit "Mahito" was a central figure for various factions. If he didn't want to die, he had to find a way to increase his own bargaining chips.

Furthermore, transmigrating into a world he recognized had a huge advantage: the ability systems within it were clearly laid out before him. He could calmly integrate and improve his power without having to grope his way forward in the dark; he could copy mature theories.

Take, for example, the half-finished thought-imprinting he had just researched. It had never appeared in Jujutsu Kaisen, but similar theories had. Moreover, he knew exactly what Mahito (Jujutsu Kaisen version) would be capable of in the future. He could calmly master those skills in a short time, and taking them to the next level was a certainty.

And upon learning that he was a cursed spirit, his first reaction was: I need to incarnate.

In fact, Mahito didn't really know the benefits of incarnation, but he knew clearly that only after incarnating could one use the Reverse Cursed Technique. Standard techniques used negative energy, while the Reverse Cursed Technique used positive energy. Cursed spirits were beings of negative energy; therefore, they didn't need the Reverse Cursed Technique. As long as their cursed energy didn't run dry, they could slowly recover even if only their head remained. Conversely, because cursed spirits were beings of negative energy, they were fundamentally unable to use the Reverse Cursed Technique.

Mahito didn't need the Reverse Cursed Technique either, but he needed to experience it firsthand. He didn't have to possess it, but he couldn't afford to be ignorant of it.

All technology required the accumulation of predecessors. If he wanted to go further, he needed to know as many techniques as possible. As a very special technique, the Reverse Cursed Technique was of paramount importance. He didn't need to know how to use it himself, but he had to possess the knowledge of such a technique. For this reason, incarnation was a must.

Aside from the Reverse Cursed Technique, Mahito had no idea what other benefits incarnation offered, but those who stood at the pinnacle of this world all possessed physical bodies. Even Tengen, who was "ascending to a higher level of existence," had maintained a human body for a long time. He didn't know the benefits of this, but since following suit certainly wouldn't hurt, he would simply imitate them. He could figure out the rest later.
