Introduction to Yorozu and Sukuna
In the expansive lore of Jujutsu Kaisen, few relationships are as twisted and one-sided as the one between Yorozu and Sukuna. Yorozu, a powerful sorcerer from the Heian Era, was reincarnated into the modern world during the Culling Game. Her character is defined by a singular, overwhelming drive: a romantic obsession with Ryomen Sukuna, the King of Curses. Unlike others who fear Sukuna’s absolute malice, Yorozu views his solitude and strength as the ultimate form of beauty, believing that she is the only one capable of teaching him about love through a battle to the death.
The Heian Era Flashback: A Deep Dive into Their History
To understand the depth of this connection, we must look back at the Heian Era flashback provided in the manga. This period, known as the Golden Age of Jujutsu, was a time of legendary sorcerers and unparalleled brutality. During a harvest festival, Yorozu first encountered Sukuna and was instantly struck by his presence. While others bowed in terror, Yorozu was moved to a state of ecstatic worship. This flashback reveals that Yorozu was a prominent sorcerer in her own right, holding a position of some status, yet she was willing to discard everything for a moment of Sukuna's attention. Her pursuit of him was relentless, even in an era where he was at the peak of his terrifying power.
Analyzing Yorozu's Obsession with the King of Curses
Yorozu's fixation is not love in any traditional sense; it is a parasitic, narcissistic obsession. She believes that because Sukuna is the "strongest," he is inherently lonely. In her mind, the only way to alleviate that loneliness is for him to be killed by someone who "loves" him more than anyone else. This creates a dangerous dynamic where her goal is not to win the fight, but to be the one who finally touches his heart through violence. Her obsession is so profound that she made a binding vow to reincarnate specifically to find him again, showing that her devotion transcends time and the cycle of life and death.
The Power of the True Sphere Technique
Yorozu’s combat prowess is centered around her incredible "Construction" cursed technique, which she refined through years of research. While she often uses liquid metal to create versatile armor and weapons, her ultimate achievement is the True Sphere. The True Sphere is a mathematical impossibility brought to life:
- Infinite Pressure: Because the sphere has a mathematically perfect point of contact, it exerts infinite pressure upon anything it touches.
- Unstoppable Destruction: There is no material or cursed energy reinforcement that can withstand its impact.
- Imperfect Construction: Despite its perfection, the technique is incredibly taxing on the user’s cursed energy and focus.
The Tragic Fate of Megumi's Sister, Tsumiki Fushiguro

The horror of Yorozu’s return is compounded by the fact that she was reincarnated into the body of Tsumiki Fushiguro, Megumi sister. For years, Megumi’s primary motivation was to protect Tsumiki and find a way to wake her from her cursed coma. The revelation that her soul had been suppressed and her body overtaken by Yorozu was a crushing blow to the young sorcerer. This was a calculated move by Kenjaku and Sukuna to break Megumi's spirit. By forcing Megumi to watch his sister's body engage in a lethal battle—and ultimately seeing Sukuna use Megumi’s own Ten Shadows Technique to kill her—the King of Curses successfully submerged Megumi’s soul in darkness, allowing Sukuna to take full control of the boy's body.
Conclusion: The Impact of Yorozu's Final Gift
The battle between Yorozu and Sukuna ended as many expected, with the King of Curses emerging victorious. However, Yorozu’s death was not without a final, cryptic contribution. As she faded away, she left behind a "gift" created through the last of her cursed energy. This object, later revealed to be the Cursed Tool Kamutoke, represents the culmination of her life’s obsession. Even in death, Yorozu sought to be useful to her "beloved," providing him with a weapon from his original era. Her legacy in Jujutsu Kaisen remains one of tragedy and terror, highlighting the devastating consequences when ancient obsessions collide with the lives of the modern generation.
