Jujutsu Kaisen Fan Theories and Conspiracy Theories

In the world of Jujutsu Kaisen, cursed energy born from human negativity is shaped by sorcerers and curses in an endless, brutal conflict. Beneath the surface of this clear dichotomy, however, lies a tangled web of ancient pacts, biological manipulation, and cosmic horror. Fan theories dissect the series’ dense lore, suggesting that the jujutsu world is not a natural ecosystem, but a deliberately maintained farm, a failed exorcism on a planetary scale, or a game with rules written by the first and worst of curses.

Note: This is only fan theories, not necessary the official truth about real canon story. For the newbie, get a lot of experience with the anime and manga before reading this page.

Theory 1: Cursed Energy is a “Leak” from a Higher, Malevolent Dimension

Cursed energy is treated as a natural byproduct of human emotion. A cosmic horror theory inverts this: it is not native to the human world. It is a corrupting influence leaking in from an adjacent, purely negative dimension, perhaps one that houses the true, formless versions of the Disaster Curses. Humans, with their complex emotions, are simply the most efficient conductors and transformers of this foreign energy. Jujutsu sorcery is then the art of safely channeling this invasive force, a constant battle against a slow, psychic infection of reality.

Theory 2: Tengen is Not a Benevolent Guardian, But the Source of the Problem

Tengen, the seemingly immortal Star Plasma Vessel and linchpin of jujutsu society’s stability, is shrouded in mystery. A pivotal conspiracy theory posits that Tengen is not a solution, but the original curse or the focal point of a catastrophic ancient binding. Their “evolution” and need for mergers might be a slow transformation into something monstrous. The entire jujutsu system—the schools, the barriers, the need for Star Plasma Vessels—exists not to protect humanity from curses, but to maintain Tengen’s unstable stasis, making the world a hostage to a single being’s deteriorating condition.

Theory 3: The “Golden Age of Jujutsu” was an Attempt to Eradicate Cursed Energy That Backfired Catastrophically

The Heian Era is remembered as a peak for sorcerers and curses alike. This theory suggests it was not a natural era, but the result of a colossal, failed ritual. Ancient sorcerers, perhaps led by figures like Sugawara no Michizane (Gojo’s ancestor), attempted to permanently purge cursed energy from the world. The ritual instead amplified and solidified it, giving birth to the first truly intelligent, legendary Cursed Spirits and creating the horrific equilibrium that defines the present. The modern era is living in the long aftermath of that mistake.

Theory 4: Kenjaku’s Plan is to “Complete” the Human/Cursed Energy Hybrid

Kenjaku, the brain-hopping ancient sorcerer, has orchestrated events for over a thousand years, culminating in the merger during the Culling Games. His goal is often stated as “evolution.” A specific theory proposes he aims to force a planary synthesis where the line between human and curse is permanently erased. He doesn’t want a world of curses or a world of humans; he wants a new, single species that fully embodies and controls cursed energy as a birthright, ending the conflict by eliminating one side of the equation: humanity as it currently exists.

Theory 5: Yuji Itadori is a “Failed Vessel” Created to Understand Sukuna, Not Contain Him

It’s revealed Yuji was engineered by Kenjaku to be Sukuna’s vessel. But what if containing Sukuna was only Phase One? This theory suggests Yuji’s unique body and ability to suppress Sukuna were meant to be a laboratory for studying the King of Curses’ essence. Kenjaku may have planned for Sukuna to eventually break free or be extracted, leaving behind a Yuji whose body and soul have been irreversibly altered by the experience, becoming the perfect base or component for Kenjaku’s final ritual—a vessel refined by the strongest curse.

Theory 6: The “Culling Games” are a Giant Ritual to Redefine the Rules of Jujutsu

The Games aren’t just a battle royale; they are a structured contest with clearly defined rules administered by a quasi-sentient barrier. This theory posits the Games themselves are a large-scale, living jujutsu ritual. The points, the colonies, and the killings are not the goal but the process. The true purpose is to generate an immense, concentrated mass of cursed energy and human suffering under specific, rule-bound conditions to rewrite the fundamental laws of cursed energy on a national or global scale, creating a new paradigm that Kenjaku can control.

Theory 7: The “Disaster Curses” are Anthropomorphic Principles, Not Just Powerful Spirits

Mahito, Jogo, Hanami, and Dagon represent fundamental human negatives: humanity, earth, forest, ocean. A philosophical theory suggests they are not mere accumulations of fear, but manifestations of primal concepts. They are closer to living laws of nature in a world corrupted by human perception. Their intelligence and drive come from being embodied ideas. Defeating them individually doesn’t eradicate the concept; it might only temporarily disperse it, meaning true victory over them is impossible as long as humanity and the planet exist.

Theory 8: Satoru Gojo’s Existence is an Unnatural “Glitch” in the Jujutsu World’s Balance

Gojo’s overwhelming power is treated as a miracle. This theory frames it as a systemic anomaly. The Six Eyes and Limitless technique combination is so powerful that it destabilizes the entire equilibrium of jujutsu society and the curse ecosystem. His birth forced curses to evolve rapidly (leading to the intelligent Disaster Curses) and made the conservative jujutsu elders paranoid. He is less a person and more a living, walking escalation of the conflict, a positive feedback loop made flesh. His sealing was perhaps an inevitable “correction” the world attempted to apply.

Theory 9: The “Back of the Prison Realm” is a Gateway to the Origin of Cursed Energy

The Prison Realm sealed Gojo, and its “back” is described as a void. A dimensional theory speculates it is not just a box, but a tiny puncture into the source dimension of cursed energy (from Theory #1). The “void” is that leaking, pure negative space. Anyone or anything sealed there isn’t just trapped; they are exposed directly to the raw essence of curses, which could lead to corruption, dissolution, or a horrific enlightenment. Escaping it might require understanding or contaminating oneself with this origin point.

Theory 10: The True “Jujutsu” is the Manipulation of Human Suffering, and Sorcerers are Unwilling Participants

The final, bleak theory. Cursed energy comes from negative human emotions. Jujutsu sorcerers then weaponize this energy. This makes the entire profession a macabre recycling program for human misery. Sorcerers don’t end suffering; they manage and weaponize its byproducts. The system ensures curses exist to create a need for sorcerers, who in turn generate more complex emotions (fear, hatred, grief) through their battles, fueling the cycle. True salvation would require not stronger jujutsu, but the impossible eradication of human negativity itself—a goal that makes even the strongest sorcerer just another cog in a monstrous engine.

The Engine of Suffering

Jujutsu Kaisen conspiracies revolve around a central, unsettling question: Is the jujutsu world a solution to a problem, or a symptom of a much deeper, unfixable condition? The theories suggest that every attempt to control, use, or understand cursed energy only seems to deepen its entrenchment in reality.

From Tengen’s ambiguous nature to Kenjaku’s millennia-long plot, the narrative hints that the current conflict is merely the latest phase in a self-perpetuating cycle of exploitation born from an ancient, primordial error. Sorcerers and curses may not be opposites, but two sides of the same cursed coin. The ultimate victory may not belong to the strongest technique, but to whoever can finally step outside the system entirely and refuse to play by the rules written in suffering—a nearly impossible task in a world where suffering is the very ink used to write reality’s laws.
