AnimeReviewExperts
Ever watched a battle in Jujutsu Kaisen and thought, “Wait… how exactly did they do that?” You’re not alone. The concept of Cursed Energy is at the heart of the series, shaping every fight, every technique, and even the way characters view the world. But unlike simpler anime power systems, Cursed Energy comes with its own set of rules, limitations, and mind-bending strategies.
Whether you’re binging the anime for the first time or rewatching to catch hidden details, understanding how Cursed Energy works will make each battle more exciting — and every character’s move more meaningful. From Yuji Itadori’s raw physical strength to Satoru Gojo’s jaw-dropping Domain Expansion, everything ties back to this mysterious force born from human emotion.
Basic Definition of Cursed Energy
At its core, Cursed Energy in Jujutsu Kaisen is the manifestation of negative human emotions — fear, anger, grief, hatred — that naturally flow through every person. It’s not just a magical resource; it’s a byproduct of humanity’s darker side.
Here’s what makes it unique:
- Everyone has it – Even non-sorcerers generate Cursed Energy unconsciously, though they can’t control it.
- Linked to curses – Stray, uncontrolled Cursed Energy attracts Cursed Spirits, which are physical manifestations of these negative feelings.
- Sorcerer control – Jujutsu Sorcerers train to harness, shape, and refine this energy into powerful techniques for both offense and defense.
Think of it like electricity: uncontrolled, it can be dangerous and destructive; harnessed properly, it powers everything from simple attacks to reality-bending abilities.
Gojo explains it best early in the series:
“Cursed Energy is born from negative emotions. You control it with positive emotions. If you can’t… you’re dead.”
This paradox — using calm focus to control energy born from chaos — is one of the most fascinating aspects of JJK’s power system. It adds both a psychological and emotional layer to every battle.

How Sorcerers Use Cursed Energy
In Jujutsu Kaisen, raw Cursed Energy alone isn’t enough to win battles. What separates seasoned sorcerers from doomed rookies is how they control, shape, and apply it in combat.
Channeling Techniques
Sorcerers must first learn to suppress their Cursed Energy to avoid detection, then release it deliberately for attacks. This involves:
- Focusing their mind – Staying calm is critical; emotional instability causes Cursed Energy to leak uncontrollably.
- Controlling flow – Skilled sorcerers direct energy to specific body parts for precise strikes or defenses.
- Maintaining efficiency – Wasting energy shortens stamina and can lead to fatal openings in battle.
Yuji Itadori’s journey shows this perfectly. At first, he releases energy too late, hitting enemies without maximum impact. Through training with Gojo and others, he learns to align physical strikes with energy release — the “impact at the exact moment of contact” that makes his Black Flash technique possible.
Weapons & Tools
Not all sorcerers rely solely on bare-handed techniques. Many enhance weapons with Cursed Energy to amplify their damage against spirits.
- Maki Zenin uses cursed tools like Playful Cloud, a three-section staff infused with energy for devastating close-range combos.
- Megumi Fushiguro focuses his energy into hand signs to summon Shikigami, using controlled bursts rather than constant output.
- Even Gojo Satoru enhances his physical defense with minimal, precise energy flow, relying on his Limitless technique for offense.
This weapon-energy synergy allows sorcerers to adapt to different opponents — a key reason why battles in Jujutsu Kaisen are so varied in style and pacing.

Types of Cursed Techniques
Cursed Techniques are the refined applications of Cursed Energy — the “special moves” that define a sorcerer’s fighting style. Each technique is unique, often shaped by the user’s personality, experiences, and family lineage.
Innate Techniques
Most sorcerers are born with an Innate Technique — a special ability tied to their spiritual makeup. Mastery of this technique is often the cornerstone of their combat identity.
Examples in JJK:
- Gojo Satoru – Limitless
Allows him to manipulate space itself, slowing, stopping, or redirecting attacks. Combined with his Six Eyes, Gojo can use Limitless with extreme precision while conserving energy. - Megumi Fushiguro – Ten Shadows Technique
Summons Shikigami (spiritual familiars) for offense, defense, and reconnaissance. His fighting style is strategic, using terrain and summons to control the pace of battle. - Kento Nanami – Ratio Technique
Creates a weak point at a ratio of 7:3 on any target he strikes, allowing him to cut through even tough cursed spirits with surgical efficiency.
Inherited Techniques
Some families pass techniques down through generations, much like a bloodline limit in other anime. These inherited powers often come with centuries of refinement but also heavy expectations.
The Zenin, Gojo, and Kamo clans are prime examples, with each family shaping the balance of power in the Jujutsu world.
Simple & Complex Techniques
Not all techniques are flashy. “Simple Domain” and “Barrier Techniques” are accessible to many sorcerers and can counter stronger enemies’ Domain Expansions. On the other end of the spectrum are complex, multi-layered techniques that require years of training — such as combining reversed Cursed Energy with healing while fighting.
A perfect example is Yuta Okkotsu, whose high energy reserves allow him to improvise with multiple techniques mid-battle, giving him flexibility even against elite opponents.
These techniques make Jujutsu Kaisen battles dynamic. Each fight feels like a chess match, with characters constantly adapting their abilities to the opponent’s strengths and weaknesses rather than relying solely on brute force.
Domain Expansion – The Ultimate Expression of Cursed Techniques
In the world of Jujutsu Kaisen, Domain Expansion is the ultimate display of a sorcerer’s skill, mastery, and raw power. It’s not just a stronger attack — it’s the creation of a personal reality where the user’s abilities become absolute.
What Is a Domain Expansion?
A Domain Expansion is essentially a pocket dimension created by shaping Cursed Energy into a fully realized environment. Once inside, the user’s techniques are guaranteed to hit their target. This makes Domains both terrifying and decisive — a single activation can completely turn the tide of a battle.
However, Domains have drawbacks:
- They consume an enormous amount of Cursed Energy.
- Maintaining one for too long can exhaust the user.
- If two Domains clash, the stronger one will overwrite the weaker.
Iconic Domains in the Series
Gojo Satoru – Infinite Void
First seen against Jogo in Season 1, Infinite Void traps the target in an endless expanse of information, overloading their senses and rendering them helpless. Visually stunning, it’s a perfect showcase of MAPPA’s animation blending cosmic beauty with terrifying implications. Gojo can deploy and retract it in an instant — a feat that proves why he’s the strongest sorcerer alive.
Ryomen Sukuna – Malevolent Shrine
Unlike traditional closed Domains, Sukuna’s Malevolent Shrine is an open-type Domain that manifests in the real world, giving him a massive attack radius. The environment is flooded with his slashing techniques, capable of carving through buildings and enemies with surgical precision. This not only demonstrates Sukuna’s overwhelming power but also his mastery in bending Domain rules.
Megumi Fushiguro – Chimera Shadow Garden
An incomplete Domain that submerges the area in a sea of shadows, allowing Megumi to summon and manipulate his Shikigami more freely. Despite being unfinished, it shows his creativity and hints at his future potential as a top-tier sorcerer.
Domain Counters
Characters can use Simple Domain or Domain Amplification to counter an opponent’s expansion. These defensive measures are rare but critical, as being caught inside a Domain without a counter is almost always fatal.
A well-timed Domain Expansion is the ultimate trump card, combining technical skill, strategic thinking, and psychological dominance. Watching a Domain unfold is like seeing a sorcerer’s soul laid bare — every detail of the environment reflects their identity and fighting philosophy.
How New Fans Can Understand Battles Better
For newcomers, Jujutsu Kaisen’s fights can feel overwhelming at first. Characters throw around terms like “reverse cursed technique,” “domain amplification,” or “black flash” mid-battle, and if you’re not already familiar with the mechanics, it’s easy to get lost. But with a little context — and the right watch strategy — the system starts to click.
Key Episodes to Focus On
If you want to learn Cursed Energy rules organically, certain episodes in Season 1 and the Jujutsu Kaisen 0 movie are must-watches:
- Season 1, Episode 2 – “For Myself”
Gojo’s first explanation of Cursed Energy basics, using Yuji as a hands-on training example. - Season 1, Episode 7 – “Assault”
Gojo unveils Infinite Void for the first time against Jogo, showing what a Domain Expansion can do. - Season 1, Episode 19 – “Black Flash”
Yuji and Todo fight Hanami, and Yuji lands multiple Black Flashes — a turning point in his skill mastery. - Season 2, Shibuya Incident Arc (Episodes 9–17)
Features rapid-fire examples of techniques, Domain battles, and counters. Watching these with subtitles on helps pick up the terminology. - Jujutsu Kaisen 0 (Movie)
Yuta’s battle style and immense cursed energy reserves provide a perfect example of raw talent meeting advanced technique.
Key Terms for Clarity
- Black Flash – A technique that amplifies a strike’s power by releasing Cursed Energy within 0.000001 seconds of physical contact. Rare, but devastating.
- Reverse Cursed Technique – Converts negative energy into positive energy for healing.
- Simple Domain – A small defensive technique to counter enemy Domains.
- Binding Vows – Agreements made to increase power in exchange for limitations or risks.
Suggested Viewing Order
If you’re new to the series and want to fully grasp Cursed Energy without constant rewinding:
- Watch Jujutsu Kaisen 0 first — it gives you a clean introduction to core concepts through Yuta’s perspective.
- Move into Season 1, focusing on Episodes 1–7 for foundational rules.
- Rewatch Episodes 7 and 19 after completing Season 1 — the techniques will make more sense the second time.
- Watch Season 2 with a note-taking mindset if you want to spot advanced concepts and foreshadowing.
Understanding these fundamentals early makes every battle more satisfying. You’ll start noticing small details — like a sorcerer’s stance before a Black Flash or how they subtly adjust their Cursed Energy output depending on the opponent.
Comparisons with Other Anime Power Systems
One of the reasons Jujutsu Kaisen’s Cursed Energy system feels so fresh is that it draws from familiar shonen mechanics while adding layers of complexity and psychological depth. To really appreciate it, it’s worth comparing it to other iconic anime power systems.
Nen – Hunter x Hunter
Nen and Cursed Energy share several similarities:
- Both are rooted in a person’s life force and require training to control.
- Both have distinct categories or specializations (Nen types vs. Cursed Techniques).
- Both allow for complex, highly personalized abilities.
Key Difference: Nen is more customizable, allowing users to craft unique abilities from scratch. Cursed Energy, on the other hand, is heavily influenced by a sorcerer’s innate technique, often tied to bloodline or personal disposition. Also, Nen doesn’t inherently stem from negative emotions — Cursed Energy’s emotional origin adds a psychological risk factor that Nen lacks.
Chakra – Naruto
Chakra and Cursed Energy both serve as the “fuel” for abilities:
- Chakra is a mix of spiritual and physical energy.
- Cursed Energy is purely spiritual in origin, born from human negativity.
Key Difference: Chakra can be replenished through rest or food, and overuse primarily causes physical exhaustion. Cursed Energy depletion can leave a sorcerer vulnerable to mental strain and spiritual collapse. Plus, unlike Chakra, Cursed Energy is directly tied to the existence of hostile entities (Cursed Spirits), making control a matter of survival.
Devil Contracts – Chainsaw Man
Devil Contracts in Chainsaw Man share the same high-stakes mentality as JJK’s Binding Vows:
- Both involve agreements with a cost in exchange for power.
- Both require clear terms and come with irreversible consequences.
Key Difference: Devil Contracts are pacts with external entities, whereas Binding Vows are agreements between sorcerers and themselves (or sometimes other humans) to limit their abilities in exchange for a boost. In JJK, the power remains internal and linked to one’s own Cursed Energy, whereas in Chainsaw Man, the power is often borrowed and dependent on the devil’s survival.
Why JJK Stands Out:
Cursed Energy is unique because it blends emotional management, tactical control, and supernatural technique in a way that feels organic to the story’s tone. It’s not just about “who has more energy” — it’s about who can use it most effectively under extreme pressure, while managing the emotional toll it takes.
Conclusion – Why Understanding Cursed Energy Makes JJK More Enjoyable
Cursed Energy isn’t just a flashy narrative device in Jujutsu Kaisen — it’s the backbone of the entire story. Every fight, every alliance, and every personal rivalry is shaped by how characters understand and wield this power.
For new fans, learning the rules of Cursed Energy transforms the viewing experience. Suddenly, you’re not just watching cool action sequences — you’re recognizing strategies, anticipating counters, and catching subtle character moments that reveal mastery or desperation.
For returning fans, revisiting early episodes with this knowledge unlocks a new appreciation for foreshadowing. You’ll notice how Gojo’s casual confidence is rooted in absolute control of his energy, how Megumi’s incomplete Domain hints at his untapped potential, and how Yuji’s raw talent grows into precision under pressure.
The beauty of Jujutsu Kaisen’s power system is that it rewards both casual watchers and hardcore analysts. You can enjoy the spectacle without overthinking it, or you can dive deep into the mechanics and discover that every move — every flicker of energy — tells part of the story.
