Is Yuji Related to Sukuna? What the Manga Reveals

Yes—but Yuji Itadori is related to Ryomen Sukuna through Sukuna’s twin brother, whose soul was later reincarnated as Yuji’s father, Jin. That makes Yuji connected to Sukuna in a family-like, spiritual sense, not Sukuna’s son or a straightforward blood descendant.

The Short Answer: Yuji Is Sukuna’s Nephew in a Sense

The late manga revelation gives Yuji and Sukuna a genuine connection beyond the fact that Yuji becomes Sukuna’s vessel. Sukuna had a twin brother before he was born, and the twin’s soul eventually reincarnated as Jin Itadori. Jin then fathered Yuji with a woman whose body was being controlled by Kenjaku. So Yuji is the child of the reincarnation of Sukuna’s twin.

Calling Yuji Sukuna’s “nephew” is a convenient way to describe that relationship, and it is a label commonly used by readers. It should not be taken as a conventional family-tree or genetic designation, though. The story establishes reincarnation and a family connection, but it does not lay out a normal biological lineage proving that Yuji inherited Sukuna’s genes through Jin.

There are two distinct reasons Yuji and Sukuna are linked: the family-like connection through Jin, and Sukuna’s later incarnation inside Yuji after Yuji eats one of his fingers. The second link is central to the plot, but it is not what makes them relatives.

What the Manga Reveals About Sukuna’s Twin

The key information appears late in the manga, in chapter 257, during the conflict between Yuji and Sukuna. Sukuna explains that he was a twin in his mother’s womb and that he consumed his twin before birth. He did so to survive, and the twin’s soul later reincarnated as Jin Itadori. This is the missing piece that connects Sukuna’s past to Yuji’s family.

The revelation also changes how readers understand Sukuna’s unusual origins. He was already described as a figure of extraordinary power and as someone feared and revered in the Heian era. The twin detail adds a personal and unsettling explanation for his beginning, but it does not mean Sukuna and Yuji are the same person, or that Yuji is a reincarnation of Sukuna. The reincarnated soul belongs to Sukuna’s twin.

It is worth separating what the manga states from what readers infer. The text identifies the twin’s soul with Jin’s reincarnation, and Jin is Yuji’s father. The story does not provide a detailed account of the soul’s intervening lives or a conventional genetic chart. The connection is therefore clearest as a spiritual and familial one.

Yuji’s Parents and Kenjaku’s Role

Yuji’s parents are important to the explanation. His father is Jin Itadori. His mother was Kaori Itadori, but the person who gave birth to Yuji was Kenjaku occupying Kaori’s body. Kenjaku is an ancient sorcerer who can move their brain and consciousness into other bodies, taking control of their hosts. The stitched scar across the forehead is a recurring sign of Kenjaku’s presence.

Yuji’s grandfather, Wasuke, tried to warn Jin about the woman he recognized as Kaori. He knew Kaori had died, yet she appeared again with a scar across her forehead. The story later confirms that this was Kenjaku using Kaori’s body. Kenjaku’s involvement in Yuji’s birth is not an incidental twist: it places Yuji within the sorcerer’s long-term schemes and helps explain why Yuji’s body could serve as a remarkably effective vessel for Sukuna.

That does not make Kenjaku Yuji’s biological father. Jin is his father; Kenjaku was the consciousness controlling his mother’s body during his conception and birth. The precise mechanics of Yuji’s creation and every part of Kenjaku’s plan are not spelled out as a simple family biography. The manga leaves some questions about intention and design open, even while confirming Kenjaku’s role.

Is Yuji Sukuna’s Son or a Reincarnation of Sukuna?

No to both. Yuji is not Sukuna’s son: Sukuna’s twin’s soul, not Sukuna himself, reincarnated as Jin. Yuji is also not Sukuna reincarnated. The shared connection is one generation removed through Jin, and it is tied to the twin’s soul rather than a claim that Sukuna fathered a child in the modern era.

This distinction matters because “related,” “reincarnated,” and “incarnated” have different meanings in Jujutsu Kaisen. Reincarnation refers here to the twin’s soul being reborn as Jin. Incarnation describes Sukuna taking over a living host through cursed objects—in Yuji’s case, the fingers Yuji swallowed. Yuji’s body houses Sukuna for a time, but that does not turn Yuji into Sukuna or make the two interchangeable.

Another common misconception is that the twin connection alone explains every similarity between them. The manga gives Yuji a connection to Sukuna’s family history, but it does not say Yuji inherited all of Sukuna’s abilities or personality from Jin. Their resemblance in the story is shaped by several factors: Yuji’s unusual body, Sukuna’s time inside him, and the events that awaken Yuji’s own abilities.

Why Yuji Could Contain Sukuna

Yuji’s ability to contain Sukuna is established at the start of the series, long before the twin revelation. After swallowing one of Sukuna’s fingers to save his friends, Yuji becomes Sukuna’s vessel. Unlike most people, he can suppress Sukuna and retain control of his own body. That rare compatibility is why the sorcerers do not simply treat him as an ordinary person possessed by a curse.

Kenjaku’s role in Yuji’s birth gives the manga a broader explanation for why Yuji may be so exceptional. Kenjaku had a hand in bringing him into the world, and the story connects Yuji to plans involving Sukuna. Still, the twin relationship is not presented as a complete technical explanation for vessel compatibility. It is safer to say Yuji’s origin and his unusual capacity are connected to the larger plot, rather than to claim that being Sukuna’s “nephew” automatically gives someone the ability to contain him.

Yuji’s body also becomes central to Sukuna’s plans and to the sorcerers’ efforts to stop him. A vessel is not the same thing as a willing partner: Yuji repeatedly resists Sukuna, and their conflict is one of the manga’s main struggles. The family connection does not erase that opposition. Yuji’s choices and Sukuna’s cruelty remain sharply at odds.

Do Yuji and Sukuna Share Powers?

They do show connections in combat, but the reason is more complicated than their family link. Yuji develops the Shrine technique, the cursed technique associated with Sukuna, during the late stages of the story. The manga links this development to Sukuna having inhabited Yuji’s body, leaving an imprint through that experience. It is not presented as simple proof that Yuji inherited Shrine from his father or from Sukuna’s twin.

Yuji also uses Blood Manipulation, but that has a different explanation. He consumed the remaining Death Painting Wombs, and the manga connects that act with his ability to use the technique. The Death Paintings are cursed-womb siblings created through Kenjaku’s experiments, not another name for Sukuna’s twin. Keeping these plotlines separate helps avoid treating every supernatural connection as one family inheritance.

Sukuna’s connection to Yuji: Sukuna’s twin’s soul reincarnated as Jin, Yuji’s father; later, Sukuna incarnated in Yuji as a vessel.
Yuji’s Shrine: associated with Sukuna’s presence in Yuji’s body, not clearly explained as a genetic hand-me-down.
Yuji’s Blood Manipulation: connected to consuming the Death Painting Wombs, a separate story detail.

These distinctions are useful when comparing the two fighters. Their abilities and histories intersect, but Yuji is not simply a younger copy of Sukuna. He has his own physical strengths, techniques, motives, and moral outlook.

When Is the Relationship Explained?

The answer is a manga spoiler from late in the story, not a fact revealed in the opening chapters. Early on, readers know that Yuji is Sukuna’s vessel, that Kenjaku is connected to Yuji’s birth, and that Sukuna has a history reaching back to the Heian era. Those clues do not, by themselves, establish the twin relationship. Chapter 257 supplies that crucial information.

If you are following only the anime, the revelation may fall beyond the material you have watched, depending on the adaptation’s coverage. The safest way to avoid spoilers is not to search for details about Yuji’s parentage or Sukuna’s past until you have reached the late manga chapters. The connection is designed as a major piece of retrospective context, so knowing it early can change how earlier scenes feel.

For manga readers revisiting the story, the reveal makes several details more meaningful: Kenjaku’s presence in Yuji’s family, the unusual circumstances around his birth, and Sukuna’s personal reaction to Yuji. It does not rewrite every event as a secret family drama, but it gives their confrontation a deeper connection than simple host and parasite.

Frequently Asked Questions

Is Yuji Sukuna’s nephew?
That is a reasonable shorthand: Sukuna’s twin’s soul reincarnated as Jin, Yuji’s father. The relationship is spiritual and familial rather than a clearly defined, conventional blood relationship.

Who is Yuji’s real father?
Yuji’s father is Jin Itadori. Jin’s soul is the reincarnation of Sukuna’s twin. Kenjaku occupied the body of Yuji’s mother, Kaori, and was involved in Yuji’s conception and birth.

Is Yuji a reincarnation of Sukuna?
No. The manga says Sukuna’s twin was reincarnated as Jin. Yuji is Jin’s son, while Sukuna later incarnated inside Yuji after Yuji swallowed a finger.

Did Sukuna deliberately make Yuji his vessel?
Yuji’s unusual origin is tied to Kenjaku’s schemes, and the manga connects his birth to the larger plan involving Sukuna. But the twin relationship alone is not given as a complete explanation for Yuji’s compatibility, and it should not be confused with Sukuna choosing Yuji as a biological child.

Does Yuji inherit Sukuna’s technique because they are related?
The story links Yuji’s Shrine to Sukuna’s time inhabiting his body, not clearly to genetic inheritance through Jin. Yuji’s Blood Manipulation has another source: his consumption of the Death Painting Wombs.

What the Relationship Means for the Story

Yuji’s connection to Sukuna does not make their conflict a simple battle between relatives, nor does it excuse Sukuna’s actions. Instead, it adds another layer to a struggle already shaped by possession, fate, and choice. Yuji carries a link to Sukuna’s earliest history, yet he refuses to become an extension of Sukuna’s will.

The most accurate summary is that Yuji is Sukuna’s relative in a reincarnation-based, family sense: Sukuna’s twin became Jin, and Jin became Yuji’s father. Yuji is not Sukuna’s son or reincarnation. His time as Sukuna’s vessel is a separate connection, and the manga’s careful distinction between the two is what makes the reveal matter.
