Jujutsu Kaisen is complete: VIZ identifies Volume 30 as the final volume and describes its closing conflict as Yuji Itadori trying to separate Sukuna from Megumi Fushiguro. So these ten theories are best read as retrospective interpretations, not predictions about an ending still to come. Each entry separates what the manga confirms from what fans could reasonably infer—and what remains speculation.
How to read these theories
Gege Akutami’s manga began serialization in Weekly Shonen Jump in 2018, according to VIZ. The clues below refer to the manga, not anime imagery. “Confirmed” means the completed story establishes the core idea; “disproved” means later events contradict it; and “unresolved” means the manga does not settle the interpretation. A plausible reading is not the same as an official confirmation.

For checking character and curse details, VIZ lists Jujutsu Kaisen: The Official Character Guide as a reference covering the series’ characters and curses. Its listing makes it a companion, not evidence for any theory here. The Shonen Jump fanbook page labels an Akutami interview section, but the accessible page does not expose its text; the anime site’s interview archive likewise does not, by itself, confirm manga canon.
Ten theories, tested against the completed manga
1. Yuji was made to become Sukuna’s vessel
The theory: Yuji’s unusual suitability as Sukuna’s vessel was not a coincidence; Kenjaku had a hand in creating the circumstances that made it possible.
#1 Best Overall
The clue: The manga reveals Kenjaku’s connection to Yuji’s birth and shows that Yuji can contain Sukuna without immediately being overwhelmed. Together, those facts make Yuji’s role look engineered rather than accidental.
Why it works: Kenjaku repeatedly pursues long-range plans involving cursed energy and human bodies. Yuji’s existence fits that pattern.
Counterargument: A connection to Yuji’s birth does not mean every part of Yuji’s life or every later choice was planned. The story does not make Kenjaku an all-knowing author of events.
Verdict: Confirmed in its central premise. Kenjaku’s involvement explains a major part of Yuji’s unusual origin, but it should not be inflated into the claim that he controlled Yuji’s entire fate.
2. Sukuna once had a twin
The theory: Sukuna’s extraordinary nature could be explained by a twin whose existence was absorbed or erased before birth.
The clue: The manga eventually links Sukuna to a twin in the womb and connects that history to Jin Itadori, Yuji’s father. That revelation gives a concrete basis to an idea that could otherwise sound like symbolic guesswork.
Why it works: The parallel between Sukuna and Yuji becomes more than a visual or thematic resemblance: their family histories are tied together through the twin reveal.
Counterargument: The reveal explains a connection; it does not mean Sukuna and Yuji are literally the same person or that Yuji inherited every aspect of Sukuna.

3. Yuji would eventually inherit Sukuna’s technique
The theory: Prolonged exposure to Sukuna might leave Yuji with access to Sukuna’s innate technique.
Rank #2
The clue: The manga establishes that Yuji can learn and use techniques, and later shows him using Shrine, the technique associated with Sukuna.
Why it works: Yuji’s body and soul are unusually entangled with Sukuna’s history. The possibility of a lasting imprint is more grounded than a theory based only on matching visual effects.
Counterargument: Yuji’s abilities develop through more than one cause, including training and his own circumstances. “He has Shrine” does not mean every power Sukuna used automatically transfers to him.
Verdict: Confirmed, with limits. Yuji gains access to Shrine; broader claims about inheriting Sukuna’s full arsenal go beyond what that establishes.
4. Nobara would return after Shibuya
The theory: Nobara Kugisaki might survive her apparent fatal injury and return to the story.
The clue: After Shibuya, the manga leaves her condition uncertain rather than giving readers an immediate, definitive account of her death. That gap encouraged hope, but uncertainty alone was not proof.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Why it works: The story eventually brings Nobara back, and her technique becomes important in the final conflict.
Counterargument: Before that return, readers could not infer a specific recovery or return date from the silence. A character’s absence is not a promise of a comeback.
Verdict: Confirmed in outcome. The return happens, but earlier speculation about when or how it would happen remained speculation until the manga showed it.
5. Gojo would return from the dead
The theory: Satoru Gojo might survive or be restored after his apparent death.
The clue: The series had established powerful healing and unusual interactions between bodies and souls, giving fans mechanisms to imagine a return. Those mechanisms did not amount to evidence that Gojo would use them.
Why it works: Gojo’s importance to the cast and the unresolved-feeling shock of his defeat made a comeback narratively imaginable.
Counterargument: The completed manga does not bring Gojo back to life. A theory that depends on a character’s importance is weaker than the events the story actually depicts.
Verdict: Disproved as a literal resurrection theory. Gojo’s body is used in the final battle, but that is not Gojo returning as a living character.

6. Yuta would use Gojo’s body to fight Sukuna
The theory: If Gojo fell, another sorcerer might use his body as a last-resort weapon.
The clue: The manga establishes that Yuta Okkotsu’s Copy technique can reproduce techniques under certain conditions, while the story also explores the consequences of moving a brain into another body.
Why it works: Those elements make an unsettling tactical possibility conceivable: using Gojo’s body and its abilities even if Gojo himself could not return.
Counterargument: This is not the same as Gojo secretly surviving, and the plan carries severe physical and moral costs. It also depends on specific abilities and conditions, not a general rule that anyone can inhabit anyone else.
Recommended Free Tools
Verdict: Confirmed as a desperate tactic, not a resurrection. The distinction matters: the manga depicts Yuta operating Gojo’s body, not Gojo waking up in it.
7. Megumi’s Ten Shadows could summon Mahoraga without a suicide pact
The theory: Megumi might eventually master the Ten Shadows Technique enough to control Mahoraga, the shikigami he had repeatedly summoned as a last resort.
Rank #4
The clue: Mahoraga is presented as an exceptionally difficult shikigami to subjugate, and Megumi’s summons had dire consequences. That leaves open a long-term possibility that mastery, rather than a sacrificial gamble, could change how he uses it.
Why it works: Megumi’s technique has room for development, and the story emphasizes the distinction between summoning a shikigami and controlling it.
Counterargument: The manga does not show Megumi completing that subjugation or achieving stable control of Mahoraga. Possibility is not an accomplished feat.
Verdict: Unresolved. The story establishes the challenge, not the future mastery fans might imagine.
8. The Zenin clan’s downfall was inevitable
The theory: The Zenin clan’s obsession with inherited techniques and status would eventually destroy it from within.
The clue: The clan repeatedly treats people according to their perceived usefulness, especially their cursed techniques. Maki’s exclusion and the abuse of family members show the cost of that hierarchy.

One-click scans. No signup required.
Why it works: The clan’s rules create the resentment and violence that help bring about its collapse. Its fate is not simply an outside attack on an otherwise stable family.
Counterargument: “Inevitable” is stronger than the evidence permits. Maki’s actions are decisive, and the manga does not demonstrate that no different set of choices could have changed the outcome.
Verdict: Plausible interpretation, not a supernatural prediction. The story strongly connects the clan’s values to its destruction, without proving that the ending was destined from the beginning.
9. Cursed techniques reveal a person’s identity
The theory: A character’s technique is more than a fighting tool; it can express their history, priorities, or way of seeing the world.

The clue: Techniques often have distinctive rules and uses that shape how their users approach conflict. The manga also makes the body, soul, and personal history central to several characters’ abilities.
Why it works: Reading techniques as characterization can make fights feel like clashes of values as well as tactics.
Counterargument: This is an interpretive lens, not a rule the manga says applies to every technique. A symbolic reading should not be mistaken for a hidden power mechanic or a creator-confirmed explanation.
Verdict: Plausible, but interpretive. It can enrich a reread so long as readers distinguish thematic analysis from stated canon.
10. The final conflict was always about saving Megumi, not merely defeating Sukuna
The theory: Beneath the escalating battles, the emotional goal was to separate Sukuna from Megumi and restore the person trapped beneath him.
The clue: VIZ’s synopsis for the final volume describes Itadori trying to separate Sukuna from Fushiguro. The manga’s final struggle makes Megumi’s survival and agency part of the resolution, not a side issue.
Why it works: It reframes victory as more than killing the strongest opponent: the heroes must confront what saving someone costs and whether Megumi can still choose to live.
Counterargument: This reading should not erase the practical need to stop Sukuna’s threat. Saving Megumi and defeating Sukuna are connected goals, not competing explanations for the entire battle.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What makes a JJK theory worth believing?
Use four checks before treating a compelling idea as likely:
- Direct clue: Does the manga show or state the relevant fact, or is the theory built mainly from visual symbolism?
- Assumptions: Does it require one reasonable inference or a chain of unseen events?
- Later chapters: Does the completed story support the idea, leave it open, or contradict it?
- Attribution: Has Akutami or an official source actually addressed the claim? An interview archive or fanbook section label is not the same as accessible confirmation.
That standard keeps “might be true” from turning into “the creator confirmed it.”
