Jujutsu Kaisen: Did Sukuna Have A Possible Role In Triggering Yuji’s Domain Expansion? Theory Explored

As a seasoned lifestyle expert with over two decades of immersion in manga culture under my belt, I find myself captivated by the intricacies and suspense surrounding Yuji Itadori’s Domain Expansion in Jujutsu Kaisen. The theory that his Domain may be the result of a Binding Vow is not only fascinating but also aligns perfectly with the series’ narrative thread of sacrifice, power dynamics, and character development.


As an obsessed fan of Jujutsu Kaisen, I can hardly contain my excitement for the upcoming showdown between Yuji Itadori and Ryomen Sukuna! With so many mysteries still unresolved, particularly about Yuji’s Domain Expansion, I find myself on the edge of my seat as we approach the climax. The latest chapter (265) hints at the impending final confrontation, and a popular theory among us fans is that Yuji’s Domain might have been created through a Binding Vow, perhaps even instigated by Sukuna himself. This idea intrigues me because it weaves together various storylines and provides a richer perspective on Yuji’s journey, his powers, and the destiny that could await him.

Yuji’s Domain Expansion 

In Chapter 264 of Jujutsu Kaisen, for the first time, Yuji Itadori unveils his Domain Expansion skill, which is a major leap in his jujutsu skills. But, the way it was executed leaves us wondering about the reasons behind Yuji’s sudden ability to use this power and the circumstances that triggered its activation, since he had no previous signs or evidence of being able to create a Domain before.

In Chapter 265, the questions at hand grew more urgent as Yuji and Sukuna engaged in a mysterious dialogue while exploring Yuji’s memories. The environment was dreamlike, with the two characters strolling through Yuji’s past recollections, giving the impression that they were having a poignant farewell introspection. This peculiar exchange has sparked fans to hypothesize that it might be due to a Binding Vow – an unyielding commitment or obligation that is frequently encountered in the Jujutsu Kaisen universe.

The significance of Binding Vows

The relationship between Yuji’s Domain Expansion and the sacred vows in the universe of Jujutsu Kaisen carries great importance. These sacred vows are agreements that come with strict limitations for access to potent abilities or guaranteed success. Violating a sacred vow often leads to severe penalties, such as death or loss of power.

In my expertise on lifestyle and storytelling, I must say that this intriguing narrative weaves around the core concept of Sacred Promises, which infuses a layer of depth to characters’ actions and capabilities. It’s quite possible that Yuji’s Domain Expansion is linked to such a Promise, shedding light on why his Domain emerged under particular conditions. Yet, the specifics of this Promise and the parties involved in its formation are shrouded in mystery.

Sukuna’s possible role in triggering Yuji’s Domain Expansion

As a lifestyle expert, I find myself intrigued by the fascinating dynamic between Sukuna, the notorious King of Curses, and Yuji, our protagonist. It seems plausible that their complex, often adversarial bond could have ignited Yuji’s Domain Expansion ability. Throughout the series, we’ve seen Sukuna’s presence looming over Yuji, residing within him due to his ingestion of one of Sukuna’s cursed fingers. Could this symbiotic relationship be the key to understanding how Yuji’s unique powers were awakened? It’s a theory worth exploring!

Sukuna and Yuji share a complicated dynamic, where they frequently manipulate one another to achieve their respective objectives. Yet, it’s worth noting that Sukuna carries an unusual code of honor and adherence to rules, possibly leading him to make a solemn promise with Yuji – a Binding Vow – which might have triggered Yuji’s ability to expand his Domain. This vow could be tied to a significant moment or achievement, like Sukuna recovering his Cursed Technique or Reverse Cursed Technique, as depicted in Chapter 264.

If Sukuna activated the Binding Vow, it suggests that Yuji’s Domain Expansion isn’t entirely self-made; instead, it’s an effect of Sukuna’s influence on him. This could deepen Yuji’s tragic backstory, implying that his remarkable skills are somehow contaminated by the curse he carries within him. Furthermore, this revelation would amplify the intensity of the climactic battle, as Yuji wouldn’t just be battling to vanquish Sukuna but also to regain control over his abilities and himself.

The implications of Yuji’s domain expansion and binding vow

The Binding Vow theory might profoundly influence the narrative, implying that Yuji’s use of Domain Expansion was a desperate move aimed at vanquishing Sukuna and safeguarding his dear ones. If his Domain was activated by a Binding Vow, it could hint that Yuji made a substantial sacrifice or agreed to an adverse condition in return for this power, which aligns with his character’s tendency to put others’ lives before his own.

In the storyline, we see Yuji putting himself in harm’s way to shield his comrades from danger and vanquish curses. The prospect of forging a Life-Binding Pact to obtain the power needed to combat Sukuna, despite the personal peril involved, brings an intricate dynamic to their bond. It is possible that Sukuna may acknowledge Yuji as a formidable adversary or a crucial piece in his strategies, transforming their ultimate showdown not only into a struggle of physical prowess but also a contest of resolves, beliefs, and destinies.

The idea that Yuji Itadori’s Domain Expansion in Jujutsu Kaisen may be a result of a Binding Vow made with Sukuna, adds layers to the series’ storyline, connecting themes such as sacrifice, power dynamics, and the relationship between Yuji and Sukuna. Even though this theory is yet to be confirmed, it has ignited conversations among fans, showcasing the complexity and depth of Gege Akutami’s narrative crafting.

As Jujutsu Kaisen approaches its conclusion, the future of characters Yuji and Sukuna hangs in the balance, causing much speculation. The concept that Yuji’s Domain Expansion is a Binding Vow remains largely hypothetical. Gege Akutami, the series creator, is anticipated to shed light on these matters as the fight between Yuji and Sukuna escalates. With each new chapter, fans grow more excited, knowing full well that the upcoming confrontation between Yuji and Sukuna will be a pivotal moment in the storyline.
