Jujutsu Kaisen: My spells have no limit

The sorcerer Lu Suo lived a thousand years ago and was skilled in barrier magic.

One of the basic spells, or rather, the effects of the spells, is brain swapping. It allows one's soul and brain to be transferred to another sorcerer's body, allowing them to continue living as that sorcerer and acquire the spells engraved in that sorcerer's brain.

However, it is impossible to determine how many techniques one can master.

The reason for his longevity seems to be to create an era far more exaggerated than the golden age of magic a thousand years ago, hoping to give birth to new spells that even he, a magician, has never understood through such a collision of spells.

To achieve this goal, Lu Su first made a contract with the strongest curse king from a thousand years ago, a two-faced Su Nuo with four hands, two mouths, and four eyes, so that when Su Nuo's lifespan ended, he would voluntarily allow Lu Su to cut his soul into twenty parts and store them in his twenty fingers as cursed objects for Lu Su to handle.

Over the course of a thousand years, Lu Su formed bonds with the sorcerers and even humans he favored throughout Japanese history, allowing these cursed objects, which housed their souls, to endure into the modern era and be reborn in the host bodies chosen by Lu Su.

This plan, which had been in the works for a thousand years, was also referred to by Lu Suo as the "Death Extinction Return".

Based on the situation of the little girl he saw at the police station, and considering the plot of Jujutsu Kaisen and the time period he was in, this was the only possibility Lin Yi could think of.

Lu Suo, this ancient demon, is looking for suitable targets for the sorcerers whose souls are inhabited. Given Lu Suo's experience of living for a thousand years and constantly changing identities, it would not be difficult for her to create a sect under her control in Central America.

"If I remember correctly, Rōsō's most recent identity was possessing the body of Itadori Yūjin's mother, giving birth to Itadori Yūjin, a vessel specifically designed to imprison Sukuna, and then disappearing, or perhaps faking his death to escape? Should I investigate?"

Lin Yi was somewhat conflicted. Based on the information he currently had, it seemed that the ancient demon, Lu Suo, was secretly watching the actions of the High School of Spellcasting and Xia Youjie while using the body of Yuji Itadori's mother.

Perhaps they noticed themselves, or perhaps they didn't.

However, as long as he continues to contact Xia Youjie, he will definitely be noticed. The other party might even become interested in him because of his spell, but the possibility is not high. After all, Xia Youjie's spell manipulation technique is a key part of Lu Suo's plan.

If I want to stay and master the two essential skills of a strong person, Reversal Technique and Domain Deployment, before the Shibuya Incident breaks out, then I need to let Rōsō know that I am a sorcerer. In this way, the other party will not treat me as a parasitic target of the Death Return.

Then, once Xia Youjie dies, the bond he formed with Xia Youjie will activate, and Xia Youjie will forget his existence. Then he can run away with peace of mind, or see if he can gain any benefits from these major events depending on his skill level at that time.

"Hey, it seems like there's a lot I can do. Okay, that's all for now, time for bed~"

After carefully analyzing his current situation, Lin Yi realized that the problem wasn't too serious, so he happily went to wash up and go to bed. As for the matter of entrusting someone, well, with the sorcery expert in charge, it shouldn't be a big deal, probably.

The next morning, in the courtyard of the Akasaka Guest House in Mitsukoshi Ward.

"Born of darkness, from darkness to darkness, cleansing away all filth and defilement."

Xia Youjie chanted the incantation to activate the barrier spell, and a black, semi-transparent curtain fell before the visual effect, enveloping the area.

Meanwhile, Lin Yi stood on the grass in the area, while on the other side were Xia Youjie and his family who were watching the show. The special-grade cursed spirit embryo that Lin Yi had brought last night was also being watched closely by the two special-grade cursed spirits released by Xia Youjie.

"Ichi-chan, are you ready? I'm going to recall my cursed spirit. Aren't you going to transform first?"

Xia Youjie greeted Lin Yi, and Lin Yi responded with his eyes.

Seeing this, Xia Youjie no longer hesitated. Anyway, he had enough people on his side to subdue this special-grade cursed spirit at any time. With a wave of his hand, the two special-grade cursed spirits he had summoned turned into a black shadow and were put into his palm.

Freed from its restraints, the special-grade cursed spirit that Lin Yi had just captured the night before glanced at Xia Youjie's side, first adopting a posture of responding to an attack, then disappearing from its spot and appearing in front of Lin Yi, its sharp claws, capable of cutting through steel and iron, lunging straight at Lin Yi's face.

So fast!

Lin Yi's eyes widened, and he shifted his body, narrowly avoiding the attack of the top-grade cursed spirit. A black figure appeared where Lin Yi had dodged and punched the top-grade cursed spirit in the chest, knocking it back.

Xia Youjie and his group looked at the Kamen Rider Joker suit that appeared next to Lin Yi with surprise, not quite understanding Lin Yi's actions.

"Now that I've temporarily joined you, let me tell you about the effects of my spell in this form. As you can see, I can completely separate my physical body from my spell power, allowing them to operate independently. In other words, it is now a permanent spell tool bound to my soul and body. I like to shout 'Transform!' because I think the transformation action is cool, but that doesn't mean I can only switch forms by shouting 'Transform!'"

Lin Yi stood next to the Kamen Rider Joker suit he had constructed with his own magical power. His tall and upright figure, combined with the Kamen Rider Joker suit that was a head taller than Lin Yi, made Lin Yi look like a 17-year-old delinquent high school student who was preparing to go to Egypt to beat up a centenarian.

"Just like putting down the 'tent'? The barrier effect comes much faster than the visual effect. Ichi-chan, you really keep surprising me~ Keep it up."

"I've already told you we're not that close!"

Ignoring Xia Youjie's encouragement, Lin Yi took a step forward, and the Kamen Rider Joker suit behind him merged with Lin Yi's mind, and he threw another punch at the Special Grade Cursed Spirit that he had knocked to the ground.

Meanwhile, in a room in Tokyo.

A woman is watching a video playing on a screen in front of her.

The video clearly showed Lin Yi appearing in the Lori Group building in his Kamen Rider form, the Heaven and Tyrant.

Whether it was the scene of destroying more than thirty level-three cursed spirits in the blink of an eye on the first basement level, or the scene of clashing with the cursed arts specialists Nanami Kento and his group on the rooftop, it was all recorded.

Even the scene where Lin Yi, carrying that top-tier cursed spirit, breaks through the barrier with a single punch and escapes is repeatedly watched by the woman in front of her.

"So, sorcerers of this era have actually started to keep up with the times? Are you a cursed corpse or a spell? How interesting. The one who took away a top-grade cursed spirit, Xia Youjie? Su Nuo, it seems the era of sorcery you've been waiting for has arrived."

The woman was pretty, with short hair, and it was impossible to tell her exact age from her face.

However, a noticeable stitched scar on the woman's forehead detracted from her overall beauty.

And this woman is none other than Kaori Itadori, the birth mother of Yuujin Itadori, the protagonist of Jujutsu Kaisen, and also the jujutsu master who plotted for a thousand years, Rōsaku!
