5 Shocking Theories Explaining What Happened To Yuji Itadori's Arms In Jujutsu Kaisen's Latest Chapters
The question of "what happened to Yuji's arms" has become one of the most compelling and heavily debated mysteries among *Jujutsu Kaisen* fans, especially following the intense, climactic battles in the manga. As of today, December 22, 2025, Yuji Itadori has undergone a radical and permanent physical transformation, debuting a new, monstrous appearance to his limbs that signifies a massive, game-changing power-up against the King of Curses, Ryomen Sukuna. This sudden and unexplained change has fueled countless theories, linking his new look to his mysterious origins and the dark world of Cursed Spirits.
The transformation is far from a simple injury; Yuji's arms have taken on a demonic, almost inhuman form, complete with sharp claws and an unnerving, scaly texture. This development, which appeared without a clear, chapter-by-chapter explanation, represents a significant evolution in his abilities, transitioning him from a purely physical fighter to a terrifying hybrid capable of challenging the strongest entities in the JJK universe. Understanding this change requires a deep dive into his unique biology and the latest, most complex lore from the manga's final arcs.
Yuji Itadori's Complete Profile and Power Evolution
Before his latest transformation, Yuji Itadori was already one of the most unique and physically imposing characters in the *Jujutsu Kaisen* world. His existence is a carefully orchestrated anomaly, a vessel created by the ancient sorcerer Kenjaku.
Yuji Itadori: Biography and Key Entities
- Full Name: Yuji Itadori (虎杖 悠仁)
- Affiliation: Tokyo Jujutsu High, First-Year Student

Evolution of Yuji's Core Abilities (Pre-Transformation)
Yuji's initial strength was purely physical, but his journey quickly led him to master complex Jujutsu concepts. This foundation is crucial to understanding how his body could handle the recent demonic change.
- Superhuman Physicality: Yuji possesses immense raw strength, speed, and durability, far exceeding that of a normal human or even most sorcerers.
- Cursed Energy (CE) Control: While initially unrefined, Yuji learned to flow his Cursed Energy through his body, eventually reaching a level of control that allows him to land consecutive Black Flashes.
- Divergent Fist: His signature technique, where a blow is followed by a second delayed impact of Cursed Energy. This was a precursor to his improved CE control.
- Black Flash Mastery: Yuji has landed multiple Black Flashes—a critical hit that amplifies Cursed Energy to the power of 2.5—demonstrating his exceptional synchronization with CE.
- Reverse Cursed Technique (RCT): A monumental achievement, Yuji learned to use RCT to heal himself, a feat only accomplished by a handful of the strongest sorcerers like Sukuna and Gojo. This ability is a key component to his survival in the final battles.
The Shocking Transformation: Yuji's Demon Arms Revealed
The dramatic change to Yuji's arms was first explicitly noticed in the manga during the intense confrontation with Sukuna, particularly around Manga Chapter 238 and in subsequent chapters like Chapter 248. The transformation is a visible, physical manifestation of his power-up, making him look less human and more like the entities he fights.
The transformed arms are described and depicted with several distinct features:
- Clawed Fingers: His hands and fingers are elongated and tipped with sharp, black claws, reminiscent of Sukuna's own hands when he takes a full cursed form.
- Inhuman Texture: The skin appears scaly, rough, and monstrous, suggesting an infusion of Cursed Spirit or Death Painting flesh.
- Massive Power Boost: The arms are not merely cosmetic. They grant Yuji a significant increase in physical prowess, allowing him to trade blows directly with Sukuna and even surprise the ancient sorcerer with his raw, overwhelming strength.
- Durability and Offense: These "Demon Arms" are used for devastating, close-quarters combat, acting as both a shield and a powerful offensive weapon, capable of parrying and pushing back attacks from the King of Curses.
This transformation marks the final evolution of Yuji Itadori, moving past his role as a simple vessel and establishing him as a true monster-level threat, a direct product of Kenjaku's dark ambition and Sukuna's residual influence.
Unraveling the Mystery: The Top Theories Behind Yuji's New Form
Since the manga has not yet provided a definitive, single-panel explanation for the arm transformation, the community has developed several high-authority theories, all rooted in established Jujutsu Kaisen lore.
1. The Cursed Womb: Death Paintings Consumption Theory (Most Popular)
This is the most widely accepted theory. It suggests that Yuji consumed the remaining Cursed Womb: Death Paintings (the objects that created Choso, Eso, and Kechizu) during the one-month training timeskip before the final battle.
- The Logic: Yuji is already a unique human-curse hybrid due to Kenjaku's interference. Consuming the remaining Cursed Womb objects—which are part-human, part-curse—would allow him to integrate their power, giving him a transformation similar to his "brother" Choso's ability to manipulate blood and body.
- The Evidence: The new arms look monstrous, aligning with the appearance of the Death Paintings. This would also explain how Yuji gained a potential Cursed Technique (which is still debated) and why he is so focused on fighting for his "brothers" and humanity.
2. Latent Power and Sukuna's Residual Influence
This theory posits that the transformation is a delayed, physical manifestation of Yuji's time as Sukuna's vessel. Even after Sukuna left his body, the King of Curses' immense Cursed Energy and soul resonance left an indelible mark on Yuji's physical form.
- The Logic: Yuji's body spent months adapting to and suppressing 20 fingers' worth of Sukuna's power. The "Demon Arms" are a permanent, physical mutation, a sign that Yuji's body has been irrevocably altered to handle and generate Special Grade-level power. The claws specifically resemble Sukuna's own.
- The Evidence: Sukuna himself was surprised by Yuji's strength, suggesting the power is a true evolution, not just a borrowed tool. Yuji's ability to use the Reverse Cursed Technique also points to his body completing its transformation into a perfect, high-level sorcerer's vessel.
3. A Cursed Tool Integrated into His Body
A less common, but plausible theory, is that the arms are not a biological transformation but a form of Cursed Tool that Yuji has somehow integrated into his own flesh.
- The Logic: The arms are incredibly durable and act as parrying devices against Sukuna's powerful slashes. They could be a unique tool developed by the sorcerers during the timeskip to give Yuji a defensive edge.
- The Evidence: The appearance is consistently the same, suggesting a constructed or stable form, rather than a fluid, organic transformation.
4. Kenjaku's Final Experiment
Given that Kenjaku orchestrated Yuji's birth, the arms could be the final, intended outcome of his experiment—the creation of a new kind of entity capable of transcending the human-curse boundary.
- The Logic: Kenjaku's goal was to optimize Cursed Energy through chaos. Yuji's new form is a perfect, optimized vessel, not just for Sukuna, but for Kenjaku's long-term plan to merge humanity with Tengen.
- The Evidence: Yuji's unique biology as a "Kenjaku-made" human-curse hybrid means his body is predisposed to radical, unnatural physical evolution.
5. Soul Resonance and Soul-Striking Cursed Technique
The transformation may be a visual side effect of Yuji mastering a technique that targets the soul, similar to Mahito's Idle Transfiguration.
- The Logic: Yuji's intense focus on his own soul and his ability to perceive the outline of a soul (learned from Mahito) could have triggered a change in his physical body, which is merely the vessel of the soul. He is now capable of striking the soul, and the arms are the physical tools for this ability.
- The Evidence: The arms were revealed as Yuji prepared to fight Sukuna, a being deeply connected to the concept of the soul and reincarnation. The monstrous appearance could represent the "soul's true form" beginning to emerge.
Ultimately, Yuji Itadori's transformed arms are a testament to his growth and the desperate measures required to defeat Ryomen Sukuna. Whether they stem from the residual power of the Cursed Womb: Death Paintings or his own latent, Kenjaku-engineered power, they solidify Yuji's place as one of the most powerful and fascinating entities in the *Jujutsu Kaisen* universe, and fans eagerly await the final, definitive explanation from the manga's creator.
