In the world of Jujutsu Kaisen, standard cursed energy stems from negative emotions like grief, anger, and despair. While this negative energy fuels destructive attacks and powerful barriers, it inherently destroys flesh rather than repairing it. To heal severe injuries, top-tier sorcerers must harness the reverse cursed technique. This advanced process multiplies negative energy by negative energy to produce positive energy, enabling miraculous cellular regeneration and physical healing.
Unlike the generic explanations found across the web, mastering this ability requires a precise mental shift that only a handful of characters ever achieve. If you've wondered how elite fighters like Satoru Gojo regenerate lost limbs or how Ryomen Sukuna cheats death, understanding the mechanics behind positive energy is essential. Let's break down how this healing art works, who can use it, and why it remains the rarest skill in modern jujutsu society.
The Mechanics of Positive Energy
At its core, standard cursed energy works like negative numbers in mathematics. Multiplying a negative emotion by another negative emotion yields a positive result. When a sorcerer multiplies cursed energy by itself, the output shifts from destructive negative energy to life-affirming positive energy.
Generating this positive output is notoriously difficult. Human brains are naturally wired to process negative feelings, making the intentional creation of positive energy feel unnatural to a sorcerer's internal circuitry. Most practitioners spend years trying to grasp the concept, and many die without ever sparking a single drop of positive energy.
Once generated, positive energy doesn't attack targets. Instead, it floods the body to stimulate cell division and tissue repair at an accelerated rate. If applied to a cursed spirit, which is entirely composed of negative energy, positive energy acts as a lethal poison that dissolves them from the inside out.
Who Can Use the Reverse Cursed Technique?
Very few characters in the series possess the talent or psychological makeup required to heal themselves or others. The roster of verified users remains small, and each character discovered the ability under extreme pressure.
- Satoru Gojo: After nearly dying during his fight with Toji Fushiguro, Gojo experienced an epiphany. By letting go of his mortal limits, he finally understood how to flow positive energy through his body, instantly healing his fatal wounds and unlocking his autonomous Infinity.
- Ryomen Sukuna: The King of Curses manipulates cursed energy on a level that defies normal rules. He heals others—such as Megumi Fushiguro and Yuji Itadori—with casual ease, treating fatal organ damage as a minor inconvenience.
- Shoko Ieiri: Unlike most combat sorcerers, Shoko specialized in healing early on. She is one of the few humans who can output positive energy externally to heal other people, making her invaluable to Jujutsu High.
- Yuta Okkotsu: Backed by Rika's boundless reservoir of cursed energy, Yuta quickly learned how to apply positive energy for both self-regeneration and advanced combat healing against curses.
- Kenjaku: Having lived for over a thousand years, Kenjaku has mastered numerous innate techniques, including reliable reverse cursed output.
- Kinji Hakari: During his jackpot state in Idle Death Gamble, Hakari possesses infinite cursed energy. This floods his body automatically, forcing a subconscious execution of the technique that grants him automatic, unkillable regeneration.
Self-Healing vs. Outputting Healing
A common point of confusion among fans is the difference between healing oneself and healing others. Most sorcerers who learn the technique can only apply it inward. Healing your own body requires routing positive energy through your own neural pathways, which is already an extreme cognitive challenge.
Projecting that positive energy outward to mend someone else's wounds is a magnitude harder. Shoko Ieiri and Yuta Okkotsu stand out precisely because they can transmit positive energy outside their physical vessel. If a sorcerer without output capabilities tries to heal a teammate, the positive energy simply dissipates or harms the recipient if miscalculated.

Common Misconceptions and Limitations
Many viewers assume that possessing the ability makes a sorcerer completely immortal. That's incorrect. Several strict limitations govern how much damage can be undone.
- Brain Destruction: If a sorcerer's head is completely destroyed before they can activate the technique, they die instantly. The brain acts as the control center for cursed energy, so a severed head or crushed skull leaves no time for reflexive healing.
- Stamina Drain: Healing consumes massive amounts of cursed energy and mental focus. Even Gojo can experience fatigue if he forces his brain to repeatedly repair itself during prolonged combat.
- Missing Limbs: While flesh and bone can regrow, it takes an immense amount of refined control. Sorcerers below elite tier cannot regenerate complex nervous systems or severed limbs efficiently.

Frequently Asked Questions
Can Yuji Itadori use the reverse cursed technique?
Throughout most of the series, Yuji cannot generate positive energy on his own. He relies on external help or his innate physical durability to survive injuries, though his role in the narrative forces him to adapt constantly.
Why is healing others so rare?
Directing positive energy outward requires an intimate understanding of how another person's biological and spiritual energy is structured. Most sorcerers can barely manage their own internal energy flows, making external healing nearly impossible.
Does positive energy hurt sorcerers?
No. Positive energy is life-affirming and soothing to human biology. It only acts as a destructive force when it comes into contact with cursed spirits or cursed objects that rely entirely on negative energy to maintain their form.
How did Gojo learn it during his fight with Toji?
Gojo experienced a near-death awakening. By dropping his defensive guard and viewing cursed energy from a fundamental, conceptual level, his brain clicked into the mindset needed to multiply negative energy into positive output.
