In this article, we will learn about the strongest female sorcerer in the Jujutsu Kaisen.

One who was so strong she could destroy the entirety of damn Earth!

Who is that character, you may ask? It’s Yuki Tsukumo!

One of the only four special-grade sorcerers in the Jujutsu World, standing side by side with monsters like Suguru Geto, Okkotsu Yuta, and the one and only Gojo Satoru.

In a weird way, she is responsible for the current state of the Jujutsu world, as it was after the conversation Geto had with Yuki that he took the path he did.

If all of this was not enough, she is also the reason behind Yuji’s attainment of his cursed technique!

Yes! Due to Yuki, Yuji now has his cursed technique, Soul swapping.

So, who exactly is Yuki Tsukumo, and if she is a special-grade sorcerer, then what is her cursed technique?

In this article, we will discuss exactly that! So wrap up your seatbelts and let’s get into it.

Who Is Yuki Tsukumo?

One of the only four special-grade sorcerers, Yuki Tsukumo, is described as the no-good special grade who doesn’t take on any missions and just frolics around overseas.

On top of that, she also does not see eye to eye with the authorities, just like Gojo. I guess this comes with being in a special grade. Every special grade in the Jujutsu Kaisen seems to be against the authorities in some way or another.

Yuki hates the authorities, and Gojo also hates them and has multiple times joked about killing them. Geto literally starts the movement against Jujutsu High itself.

Yuta first cheats on his binding vow regarding killing Yuji and later just kills them all. Do you see what I am saying?

Anyway, back to Yuki, she is not just strong but also very knowledgeable. She managed to do something even Gojo Satoru could possibly not do, a job that shaped the future.

She mentored Aoi Todo! A man with an IQ of 530,000, and only Yuki was capable of doing that.

About a decade ago, when Todo was in third grade, he beat up a high schooler with a shitty attitude.

After the high schooler had mocked him, he felt a deep desire to fight, but even though the guy was older than Todo, he was no match for him.

This is why Todo found it not fun to fight a boring guy like him, but that was when Yui came stumbling onto the scene. And the first question she asked Todo became his icebreaker question!

“What Kind of girls are you into?”

Yuki recognizes Todo’s talent, praises him, and eventually introduces him to the Jujutsu world.

Yuki’s Innate Cursed Technique

Yuki’s cursed technique is called Star Rage and allows her to add imaginary mass to herself and her shikigami.

Yuki and her shikigami

Yes, Yuki is also a shinigami user. Her shinigami is Garuda. The name originates from Hindu mythology in the Vedas.

Garuda is described as the king of the birds and a kite-like figure. It is generally portrayed as a protector with the power to swiftly travel anywhere, ever vigilant, and an enemy of every serpent.

During her fight against Kenjaku, she summoned the curse of an Asian deity from Hinduism, Ganesha.

Kenjaku explains that this is the fear that people have of Ganesha, and that it can entangle concepts with its targets.

Yuki then summons Garuda. It curls up in a ball, and then Yuki channels her inner Messi and kicks Garuda towards the cursed spirit, annihilating it with just one shot.

Ganesha is a special-grade cursed spirit, but it still got destroyed in one shot!

Going back to her base cursed technique, Star Rage, as explained, it allows Yuki to add mass to her and Garuda.

Kenjaku described how Yuki’s cursed technique completely neglects physics and goes beyond it. He explains that the amount of mass applied is something that can’t be comprehended or contained by the concept’s definitions and semantics.

Yuki provides insight into her technique, it is not a simple addition of mass, instead, her cursed technique is to add imaginary mass.

Yuki can apply an insane amount of imaginary mass to her and Garuda. Now it makes sense how Garuda destroyed that special-grade cursed spirit in a single hit.

This addition of imaginary mass doesn’t even have any real effect on the target, so weight or acceleration do not get affected.

Kenjaku states that Yuki is just ignoring the laws and concepts of physics, and thus he can’t even use any of his special-grade cursed spirits as she will just one-hit kill them.

To understand how dangerous her technique is, let’s see Jogo. His summoning of a damn meteor in the Shibuya arc made fans go crazy. This is nothing compared to what Yuki is capable of.

Yuki can potentially create a real Black Hole! Yes, A Black Hole. And Yuki’s maximum technique is exactly that.

But how is this possible?

Since mass and density are directly related to each other, Yuki could turn her own body into a black hole.

Black Holes are essentially huge amounts of mass in a very very very small volume, meaning they have a dangerously high density.

She could achieve this by adding an infinite amount of mass to herself, increasing density to a dangerous level, and thus producing a black Hole.

Yuki's black hole

Unlike many other maximum techniques, this is more of a Kamikaze.

Yuki is immune to the effects of imaginary mass, but only to a certain extent. Meaning her body can take an incredulous amount of mass, but since her body’s volume is finite, she has to put a limit on her ability.

Thus, Yuki uses her Maximum Technique, like Megumi, as a suicidal attack and as a last resort. This is to ensure that even if she goes down, she will take the enemy with her as well.

Guess what? She used this technique against Kenjaku and nearly killed him. It was so strong that if Tengen’s barrier had not been there, the whole thing would have been destroyed. But Yuki knew it.

She knew Tengen’s barrier would protect the outside world. Unfortunately for Yuki, Kenjaku survived.

He survived thanks to the cursed technique of his last host, Yuji’s mother, Kaori. This cursed technique was called antigravity.

The anti-gravity repelled the force of the black hole and protected Kenjaku.

But her death was not in vain, as this helped Choso escape with the back entrance of the prison realm and Yuki’s research on Souls.

Choso getting away with the back of the prison realm allowed Gojo’s reentrance in the series, and the research book helped Yuji find his cursed technique, Soul Swapping!

This is how, even after her death, Yuki is still affecting the Jujutsu society.
