Incantations and Hand Signs
Cursed techniques often require hand signs, power words, or other gestures to be activated.
This situation is frequently illustrated by Megumi Fushiguro when he summons a shikigami.
A sorcerer's skill depends on their ability to minimize—or even omit—these elements to optimize their power in the heat of combat.
Conversely, the deliberate incorporation of incantations or rituals can increase the effectiveness of a cursed technique.
How is this possible?
The answer is obvious: vows.
Jin made an embarrassing vow—one he never thought he would utter—to maximize the power of Yaga's technique.
A ritual with a satanic and clichéd appearance.
Unfortunately, it didn't work completely.
Nayuta was compatible with Kaori, but her body rejected the information from the other two cores.
"She's compatible enough with Kaori that I don't even need to finish the incantations. However, the other spiritual information is rejected," Jin analyzed, frowning at the situation.
As he observed the frail little body on the operating table, Jin's face took on a serious and slightly pale expression.
'Jin Itadori… I hope your love for your wife was mutual,' he thought while taking out two more cores.
The first did not belong to an ordinary sorcerer, but to Sukuna's deceased brother.
How was that possible?
Simple.
Jin had recovered a bit of Wasuke Itadori's DNA after his family dinner.
Once the operation was complete, he had tried to extract abnormal spiritual information within his father's body.
The idea was to attempt to reproduce the particularity of Sukuna's brother using the reincarnation of the latter.
The result was this core of information, which Jin wasn't even sure could truly be considered a core.
In the end, he was going to use it sooner than expected.
As for the second core, it came from Jin Itadori himself.
"Sh-She accepted all of them?" he muttered in disbelief.
Nayuta now possessed three cores, but the task was not yet fully complete.
Unlike Jin's first creation, he did not want Nayuta to be weak or to have ordinary Grade 1 strength.
However, he also did not want to grant her an absurd potential, to avoid losing control over the little girl born from this experiment.
'I really don't want to share the power of the guild card, so I specifically used the information from Jin Itadori and not mine,' he thought while tracing more esoteric symbols on the floor with his blood.
These symbols were not there by chance, since Jin planned to spend the entire night here performing incantations.
He was carrying out this ritual because he had integrated this procedure as a condition to fully use Yaga's technique.
It was an annoying vow, but Jin was determined.
If anyone could observe this place, they would see a family man standing in front of the corpse of a little girl, performing satanic incantations in Latin.
Of course, the demonic circle on the floor would do nothing to exonerate Jin.

"Open your mouth… haa."
"… No Jin, you won't buy me—"
*ball enters the mouth*
Jin nodded in satisfaction as he watched Kaori chew the food, despite her apparent bad mood.
A month had passed since Jin's first meeting with Rasputin. Since that day, the relationship between Jin and Kaori had deteriorated considerably.
As for the reason?
Irresponsibility.
Jin had spent a night away without caring about Kaori's opinion, even though he was a married man and soon-to-be father.
Kaori had decided to punish him by forcing him to sleep on the couch.
Unfortunately for Kaori, this action was perceived as a relief by her husband.
Contrary to the preconceived ideas of the millennium-old sorceress, Jin did not want sex and was not frustrated by the doctor's recommendation to minimize sexual intercourse.
Kaori's pregnancy was in a critical stage, according to Dr. Kuro.
Jin was even secretly happy to leave the bedroom, because he could sleep peacefully without intrusive thoughts related to Kaori's physique.
Many Jujutsu Kaisen readers are unaware of this, but Gege Akutami once confirmed Jin's preference in women: tall and curvy.
The mangaka specified that Jin and Yuji both like the same type of woman during a Q&A session.
What does that mean? Kaori Itadori has a physique similar to actress Jennifer Lawrence…
How could a hardened single man stay calm in bed with such a woman so close to him?
The only thing that had stopped him multiple times was imagining Geto saying: "Sorry, but I prefer Satoru."
That sentence alone was more than enough to cool his urges.
"Indeed, I can't buy Kaori's heart since it's already mine~" he said while offering another bite toward Kaori.
She frowned, clearly annoyed, but still opened her mouth to eat the meal Jin was offering her.
Kaori pretended to chew reluctantly, but the reality was quite different.
'Why is this so good?' Kaori thought while stealing furtive glances at her husband's dish.
The original Jin was not a good cook. However, Jin's cooking skill was formidable after being combined with the Reading skill.
He only needed to possess sufficient culinary knowledge to turn ingredients into high-quality meals.
Jin had reached level 2 and learned it recently, because he judged that mere survival wasn't enough in this new life.
After all, didn't he have the right to have fun? To enjoy the small things of everyday life?
When would he have time to live for himself?
So he had invested in this skill.
A stupid choice? Yes.
However, Jin didn't care and regretted nothing.
"Hm… if you think your sweet words will get you back in bed, you're wrong, you liar," she said while getting up from the table.
Jin had the impression that Kaori was putting a little too much emphasis on the word "liar," but the idea vanished immediately in the face of his wife's next actions.
At an almost inhuman speed, Kaori grabbed the food in front of her, claiming she wanted to clear the plates.
'Clear them? Why the hell does she need to leave the kitchen for that…' he thought before realizing the magnitude and perfidy of his wife.
The food was stolen mercilessly by Kaori!
"Wait a minute, you didn't—" Jin wanted to stand up to intercept Kaori before she ate everything,
But a thud caught his attention. Immediately, he rushed reflexively toward Kaori.
Even though Claud knew that the woman under his roof was a powerful existence in this universe, Jin's body reacted on its own to the idea that Kaori was in danger.
It took him only a few seconds to reach Kaori's location, thanks to his hearing.
On site, Jin witnessed a sight he never thought he would see coming from his wife.
"J-Jin… I-I'm going into labor…" Kaori stammered, already in labor.
