Jujutsu Kaisenis set to go down as one of the most unique shonen series ever released, and its protagonist,Itadori Yuji, is responsible for making the series unique. Yuji brings a unique charm to the series that has won over many fans, but he has also faced criticism for his unconventional portrayal. Unlike many other shonen protagonists,Yuji doesn’t have grand ambitions or dreams, and he even openly admits that he sees himself as just a cog in a larger machine.
This aspect of Yuji hasn’t been universally accepted, as his character resonates differently with fans who weren’t expecting this kind of approach in a Shōnen series. However, it is this self-awareness that has propelled Yuji into becoming a stronger character, even allowing him to unlock the mysterious Domain Expansion, the pinnacle of a Jujutsu Sorcerer.Yuji’s mastery of Domain Expansionnot only perfectly encapsulates his character but also demonstrates how sorcerers can reach new heights.

Yuji’s Domain Expansion Explains How Sorcerers in Jujutsu Kaisen Evolve
The Mastery of Domain Expansion Requires Self-Awareness
AsYuji is not seen as an expert Jujutsu Sorcererand his specialty lies in physical prowess, much like Maki, fans were intrigued to see how the protagonist would achieve this technique.Yuji was able to unlock Domain Expansion during his fight against Sukunain Jujutsu Kaisen Chapter #265. Much of how Yuji was able to achieve this technique still remains a mystery, as the series has never emphasized how a sorcerer actually masters Domain Expansion.
While the series has explained many other complex techniques in detail, the explanation of Domain Expansion mainly revolves around mastery over barrier techniques and an innate cursed technique, deeming it the pinnacle of sorcery. However, there is a clear way to understandhow Yuji was able to unlock his Domain Expansion.Yuji’s Domain essentially works by tearing apart the souls of his opponents, specifically awakened sorcerers, as the series emphasizes. This is quite different from what fans anticipated, as many believed his Domain would elevate his physical prowess to a new level.

This belief stemmed from the idea that a sorcerer’s specialty is what gets elevated within Domain Expansion. But the key lies in understanding how this technique truly works: it requires the sorcerer’s acknowledgment of their true specialty. Until the events of the Shibuya arc and the trauma that followed, Yuji saw himself as merely a cog in a grand machine. However, after witnessing the devastation caused by Sukuna during and after Shibuya,Yuji came to believe his true role was to kill Sukuna.
At the end of the day,Domain Expansion is a manifestation of a sorcerer’s mental scenery, allowing them to fight with their specialty and a guaranteed hit effect. With Yuji’s mastery of this technique, it’s clear that mastering Domain Expansion ultimately lies in self-awareness and confidence. This idea has been exemplified in many other characters throughoutJujutsu Kaisen, and no one explains it better than Gojo Satoru.

Gojo Became a God-Level Sorcerer With His Confidence
Knowing No One Else Was as Blessed as Him, Gojo Truly Became the Honored One
Gojo Satoru is truly aspecial and memorable character in theJujutsu Kaisenseries. Not only did he inherit the Limitless Technique from the Gojo family, but he was also blessed with the Six Eyes. Gojo’s cursed energy prowess is extraordinary because he believed he was born special. However, it wasn’t until his encounter with Toji that he truly awakened as a sorcerer. In this fight, Gojo is pushed to his absolute limit, and after coming close to death, he unlocks the Reversed Cursed Technique.
When It Comes to Unanswered Questions, Jujutsu Kaisen Is One of Anime’s Worst Offenders
Jujutsu Kaisen was a cultural phenomenon, but the manga left much to be desired in terms of world-building and character development.
This moment becomes symbolic for Gojo. Until then, he had only been told by others that he was special. But after this near-death experience, he finally starts to believe it himself. From that point on, Gojo, considering himself “the honored one,” goes on to accomplish feats and reach heights that will be impossible for most others.
Given that there is a part of every sorcerer’s brain responsible for the generation of cursed energy, it is heavily implied that the limit of one’s ability to produce and efficiently use cursed energy in sorcery lies in confidence: as much confidence a sorcerer has, the ability to materialize thoughts is greater. This is why Yuji’s achievement of Domain Expansion inJujutsu Kaisen, despite having only recently entered the jujutsu world and lacking years of training, underscores that self-awareness and confidence have always played a crucial role in a sorcerer’s journey.
