When you hear the name “Sukuna” in Jujutsu Kaisen, it immediately brings to mind pure terror, power, and ancient evil. Known as the King of Curses, Ryomen Sukuna is one of the most feared and dominant figures in the entire series — a being whose presence reshapes the rules of the world itself.
Though Sukuna is introduced as a dormant force within Yuji Itadori, his growing presence, intelligence, and raw power have made him one of anime’s most iconic modern villains.
Who Is Sukuna?
Sukuna, whose full title is Ryomen Sukuna, was once a human sorcerer over a thousand years ago during the Golden Age of Jujutsu. However, he was so powerful, twisted, and cruel that when he died, even death couldn’t fully contain him.
His power was sealed into 20 indestructible fingers — cursed objects scattered across the world. These fingers became so dangerous that consuming even one would give a curse immense power.
In the present day, Yuji Itadori swallows one of those fingers — unknowingly becoming the host of Sukuna.
Sukuna’s Appearance
Sukuna shares Yuji’s body, but when he takes over, his look becomes distinctly horrifying:
- Black tattoos appear all over Yuji’s body
- His eyes become sharp and sinister, often with two extra eyes appearing
- His expression becomes cruel and smug
- His voice deepens and drips with malice
He looks like a demon wearing a human shell, and his aura shifts everything around him into a field of dread.
Sukuna’s Personality
Sukuna is:
- Arrogant and sadistic — he enjoys causing pain and watching others suffer
- Highly intelligent — he calculates situations, even from within Yuji’s mind
- Prideful — he sees almost everyone as beneath him
- Strategic — Sukuna doesn’t act without a plan, especially when it comes to his resurrection or fighting other top-tier sorcerers
- Independent — he only makes deals if they benefit him completely
Unlike some villains who have tragic backstories or moral complexity, Sukuna embraces being a villain to the core — and that’s what makes him terrifying.
Sukuna’s Powers and Abilities
Even with just a portion of his full power, Sukuna is overwhelming. As Yuji consumes more fingers, his strength multiplies. At full potential, he becomes godlike in battle.
Cursed Energy Mastery
Sukuna manipulates cursed energy with perfect control. His attacks are brutal, precise, and efficient — blending destruction and technique with ease.
Cleave and Dismantle
These are Sukuna’s signature slashing attacks:
- Cleave adjusts itself depending on the target’s toughness
- Dismantle is a free-form slash that cuts through anything
He uses these to tear through enemies in seconds, even slicing entire monsters in half.
Domain Expansion – Malevolent Shrine
This is one of the most horrifying domains in Jujutsu Kaisen.
Unlike most domains that require barriers, Sukuna’s shrine automatically slashes everything in a vast area with precision — a true display of god-tier technique.
He doesn’t trap opponents — he massacres them instantly.
Reverse Cursed Technique
Despite being a killing machine, Sukuna can also heal himself and even others using reverse cursed energy. This makes him nearly impossible to kill unless he’s completely sealed or erased.
Binding Vows
Sukuna makes a secret vow with Yuji — agreeing not to harm others under certain conditions. But of course, he twists this to his advantage later, revealing how dangerous deals with him can be.
Sukuna and Yuji: A Battle of Willpower
Yuji Itadori, the protagonist, is Sukuna’s unwilling host. Their relationship is a constant mental tug-of-war.
At first, Yuji is able to suppress Sukuna. But as the series progresses and more fingers are consumed, Sukuna gains more influence.
Their conflict is about:
- Control vs. Chaos
- Compassion vs. Cruelty
- Sacrifice vs. Domination
It’s not just a fight for Yuji’s body — it’s a battle for his soul and the fate of the world.
Sukuna’s Role in the Story
Sukuna isn’t just a background threat — he’s central to the plot’s evolution.
Some key moments include:
- Shibuya Incident: Where he takes control and wipes out an entire area, showcasing his true power
- Fighting Mahoraga: He defeats the most powerful shikigami, proving he’s a god among curses
- Possessing Megumi Fushiguro: Later in the series, Sukuna uses a clever strategy to switch vessels — showing just how cunning he is
Sukuna is the chaos engine of Jujutsu Kaisen. Every time he appears, something massive and irreversible happens.
