It was late one Saturday night, just a few weeks back, and I was deep into one of those endless online debates with my buddies. We’d just binged the latest Jujutsu Kaisen season, and the sheer destructive power of Sukuna, especially that terrifying Malevolent Shrine, had us all buzzing. Then, like a bolt from the blue, my pal Mike—always the provocateur—threw down the gauntlet: “Think 20-finger Sukuna could actually take down Kurama?” The room went silent. We’d all seen the Nine-Tails unleash absolute chaos, leveling mountains and shaking entire nations. Could the King of Curses, even at his peak, truly stand a chance against a force of nature like that? The question, frankly, had been bugging me ever since. It’s a clash of titans that pits raw, ancient demonic power against primordial, world-shaking chakra.
So, to answer the burning question right off the bat: **The fight between 20-finger Sukuna and Kurama is incredibly close, leaning towards Sukuna in a majority of scenarios due to his strategic depth, highly potent and unavoidable Domain Expansion, and precision attacks, assuming Cursed Energy can affect Chakra-based entities.** While Kurama possesses unparalleled destructive force and durability, Sukuna’s unique abilities, especially Malevolent Shrine, offer a decisive advantage that bypasses conventional defenses.
Let’s dive deep into this hypothetical battle, peeling back the layers of both characters’ abilities, power scaling, and tactical approaches to truly understand who would come out on top in this epic, dream matchup. This isn’t just about who hits harder; it’s about the nuances of their respective power systems and how they might interact.
The King of Curses Unleashed: Understanding 20-Finger Sukuna
Ryomen Sukuna, the undisputed King of Curses, is an entity of pure malevolence and immense power. When we talk about “20-finger Sukuna,” we’re discussing him at his absolute apex, fully incarnated and with all his powers restored, as depicted in the Jujutsu Kaisen manga. This isn’t some weakened host; this is the genuine article, a force of nature that terrorized the golden age of Jujutsu and continues to be the benchmark for destructive potential in his universe.
My own take? Sukuna isn’t just strong; he’s intelligent, sadistic, and utterly ruthless. He doesn’t fight for glory or justice; he fights for the sheer joy of it, and to prove his own superiority. This psychological edge, combined with his overwhelming power, makes him a truly terrifying opponent.
Let’s break down his arsenal:
Cursed Energy and Physical Prowess
Sukuna’s cursed energy reserves are astronomical, far exceeding even the most powerful special-grade sorcerers. His output is equally monstrous, allowing him to effortlessly decimate landscapes. Beyond his mystical abilities, his physical strength, speed, and durability are top-tier, even in a cursed spirit body. He can withstand incredible punishment and move at speeds that appear instantaneous to the average eye. His mastery over cursed energy also grants him a highly effective Reverse Cursed Technique, allowing for near-instantaneous healing of grievous wounds, even reattaching limbs. This healing factor is a massive advantage in any prolonged engagement.
Innated Techniques: Dismantle and Cleave
- Dismantle: This is Sukuna’s basic, invisible slashing attack. It can target inanimate objects or non-cursed energy users without much conscious effort. It’s fast, precise, and can cut through almost anything.
- Cleave: This is a variable slashing attack that adjusts its output based on the target’s cursed energy resistance. The stronger the opponent, the harder Cleave cuts. This technique is particularly terrifying because it bypasses conventional durability; instead of simply hitting harder, it *adjusts* to cut more effectively. For a massive, durable entity like Kurama, Cleave would be continuously calibrating itself to deliver maximum damage.
These techniques make Sukuna incredibly dangerous at range and in close quarters. The sheer number of slashes he can unleash in an instant can turn an opponent into ribbons before they even realize they’ve been attacked.
The Flame Technique: “Fuga” (Fire Arrow)
While less frequently used, Sukuna possesses a powerful fire-based technique, typically manifested as a massive, concentrated arrow of flames. The destructive potential of this technique is immense, capable of incinerating a vast area and leaving nothing but scorched earth. Its exact mechanism, whether it’s an innate technique or a stored ability, is still a subject of debate among fans, but its power is undeniable. This adds a powerful, wide-area destructive option to his arsenal, contrasting with the precise nature of his slashes.
Domain Expansion: Malevolent Shrine
This is Sukuna’s ultimate weapon and arguably the most formidable ability in his repertoire. Unlike most Domain Expansions that create a confined space, Malevolent Shrine manifests a shrine with a demonic visage and an open barrier. This “open barrier” is what makes it unique and incredibly dangerous:
- Guaranteed Hit: Within the Domain’s immense range (up to a 200-meter radius), every target is subjected to a barrage of Dismantle and Cleave slashes. These attacks are not only incredibly numerous but also *guaranteed to hit*. There is no dodging, no blocking in the traditional sense.
- No Escape: The open barrier means there’s no way to escape the Domain by destroying it from the inside, a common strategy against other domains. Targets are simply trapped within the area of effect.
- Overwhelming Output: The sheer volume and speed of slashes delivered by Malevolent Shrine are mind-boggling, effectively turning the affected area into a meat grinder.
The strategic implications of Malevolent Shrine are profound. It allows Sukuna to bypass defensive abilities, overwhelm opponents with raw damage, and effectively dictate the terms of engagement within a massive area. For an opponent like Kurama, whose primary defense is sheer durability, a guaranteed-hit attack like Malevolent Shrine presents an existential threat.
The Nine-Tailed Beast: Understanding Kurama
Kurama, the Nine-Tails, is one of the most iconic and powerful entities in the Naruto universe. A massive, ancient being of pure chakra, Kurama embodies destruction and raw power. While often seen in conjunction with Naruto, for the purpose of this fight, we’re considering Kurama at its peak, fully manifested and unleashed, similar to its rampage on Konoha or its full power during the Fourth Great Ninja War. This means we’re looking at its independent capabilities, not just how it functions as a power source for Naruto.
When I first saw Kurama’s full-scale rampage, it was clear that this wasn’t just a big fox. It was a natural disaster given form. The sheer destructive capacity it commanded was mind-boggling, easily dwarfing entire landscapes. This level of power puts it in a very exclusive club of fictional beings.
Let’s dissect Kurama’s formidable power:
Chakra Reserves and Physical Dominance
Kurama possesses an inexhaustible, almost infinite supply of chakra. This vast reservoir allows it to sustain battles for extended periods, generate colossal amounts of destructive energy, and maintain its massive physical form without tiring. Physically, Kurama is a behemoth. Its sheer size grants it incredible physical strength, capable of leveling mountains with a swipe of its tail or a punch. Its speed, despite its size, is also impressive, capable of keeping up with high-tier ninja and moving across vast distances quickly. Durability is another hallmark; Kurama can shrug off attacks that would devastate entire platoons of shinobi, including powerful ninjutsu and physical assaults.
Tailed Beast Bombs (Bijuudama)
The Tailed Beast Bomb is Kurama’s signature and most destructive attack. This technique involves gathering and compressing a massive amount of chakra into a dense, spherical blast.
- Destructive Power: A single Bijuudama, especially a fully charged one, is capable of annihilating landscapes, vaporizing mountains, and leaving massive craters. At full power, it can even clash with other Tailed Beast Bombs or powerful attacks from entities like Susanoo, causing country-level destruction.
- Versatility: Kurama can fire these in various forms: as a single, concentrated blast, a continuous beam, or even multiple, smaller blasts. This versatility allows it to attack both single targets and wide areas with devastating effect.
- Energy Basis: The Bijuudama is pure condensed chakra, a raw energetic attack that pulverizes anything in its path.
This technique is the centerpiece of Kurama’s offensive capabilities, capable of reshaping the battlefield and dealing immense, unblockable damage.
Tailed Beast Mode/Avatar
In its full, manifested form, Kurama is a gigantic, fox-like entity made of pure, fiery chakra. This avatar form provides:
- Enhanced Durability: The chakra cloak acts as an incredibly resilient armor, deflecting most attacks and allowing Kurama to withstand direct hits from powerful techniques.
- Increased Physicality: Further boosts to strength and speed, making its physical attacks even more devastating.
- Sensory Abilities: Kurama possesses acute sensory abilities, allowing it to detect chakra and threats from vast distances.
This mode is Kurama at its most powerful and destructive, a walking, roaring force of nature.
Regeneration and Stamina
While not explicitly shown to “regenerate” in the same way as a Cursed Spirit, Kurama’s immense chakra reserves allow it to quickly recover from damage that might incapacitate lesser beings. Its stamina is virtually limitless, meaning it can maintain its peak performance and continuously unleash devastating attacks for an extended duration, a critical factor in a prolonged battle.
The Clash of Worlds: Cursed Energy vs. Chakra
Before we pit these two powerhouses against each other, we need to address the elephant in the room: how do Cursed Energy and Chakra interact? This is a fundamental challenge in any cross-verse debate. For the sake of this analysis, we’ll assume a “neutralized” battleground where both energy systems can directly affect each other. If Cursed Energy simply bypassed Kurama’s chakra defenses entirely, or vice-versa, the fight would be over too quickly to be interesting. So, let’s operate under the assumption that:
- Cursed Energy can damage and interact with Chakra and living beings from the Naruto universe.
- Chakra-based attacks can damage and interact with Cursed Energy and Cursed Spirits/Sorcerers from the Jujutsu Kaisen universe.
- Defensive abilities (like Kurama’s chakra cloak or Sukuna’s cursed energy reinforcement) provide equivalent protection against the opposing energy type.
Without this assumption, the debate becomes less about power and more about fundamental incompatibilities, which isn’t as fun or insightful.
Direct Comparison: Strengths and Weaknesses
Let’s break down where each combatant excels and where they might falter.
Offense: Who Hits Harder?
- Sukuna: His primary offensive strength lies in precision and unavoidable damage. Cleave adapts to the target’s resistance, meaning it will always cut as efficiently as possible. Malevolent Shrine’s guaranteed hit means an endless barrage of these adaptive slashes. The Fire Arrow provides a powerful, wide-area blast.
- Kurama: Specializes in raw, brute force. The Bijuudama is unparalleled in terms of sheer destructive *area* and *magnitude*. It can vaporize landscapes. Physical attacks from its massive form are also incredibly potent, capable of crushing mountains.
Verdict: Kurama wins in terms of *area-of-effect and raw destructive magnitude*. A single Bijuudama can outmatch Sukuna’s fire arrow in terms of sheer geographical impact. However, Sukuna wins in terms of *unavoidable, continuous, and adapting damage output* with Malevolent Shrine.
Defense and Durability: Who Can Take More Punishment?
- Sukuna: Possesses incredible raw durability for his size, capable of withstanding attacks from other special-grade curses and sorcerers. His Reverse Cursed Technique grants him near-instantaneous regeneration, healing from critical wounds in seconds.
- Kurama: Its sheer size and chakra cloak provide a formidable defense against conventional attacks. It has tanked powerful ninjutsu and Tailed Beast Bombs from other Tailed Beasts. Its immense chakra also aids in rapid recovery from damage.
Verdict: Kurama likely has higher raw *durability* against single, powerful hits due to its immense size and chakra armor. However, Sukuna’s *regeneration* is a massive wildcard, allowing him to recover from damage much faster and more completely than Kurama. Kurama might be able to tank more hits, but Sukuna can effectively “undo” more damage.
Speed and Agility: Who Moves Faster?
- Sukuna: In his human form, Sukuna is incredibly fast, capable of moving at blur speeds, reacting to and dodging high-speed attacks. His slashes are virtually instantaneous.
- Kurama: Despite its size, Kurama is surprisingly fast, able to leap and cover vast distances quickly, keeping up with powerful ninja. Its Bijuudama are also very fast projectiles.
Verdict: Sukuna likely has the edge in *combat speed and agility* in his human-like form, allowing him to dodge and weave. Kurama, while fast for its size, is still a giant target. Sukuna’s slashes are too fast to perceive for most opponents, giving him an advantage in close-quarters skirmishes if he can get in.
Intelligence and Tactics: Who is the Better Fighter?
- Sukuna: A tactical genius with millennia of combat experience. He is cold, calculating, and ruthless, always looking for the most efficient way to dismantle his opponent. He understands cursed energy and its applications at an unparalleled level.
- Kurama: Possesses vast battle experience and cunning, especially when paired with Naruto. However, when acting independently, it often relies on overwhelming force and primal rage rather than intricate tactics.
Verdict: Sukuna takes this category hands down. His strategic mind and millennia of perfected combat experience give him a significant edge. He won’t just throw attacks; he’ll adapt, analyze, and exploit weaknesses.
Area of Effect/Destruction Potential
- Sukuna: Malevolent Shrine covers a massive area (200m radius) with unavoidable, continuous slashes. His Fire Arrow also has significant destructive range.
- Kurama: The Bijuudama can vaporize entire landscapes, easily comparable to small nukes in terms of raw power and scale.
Verdict: Kurama has a higher potential for instantaneous, widespread *environmental destruction* with a single Bijuudama. Sukuna’s Malevolent Shrine offers a *continuous, guaranteed area-denial* effect that is arguably more lethal to a single, large target within its range.
The Battle Scenario: How It Might Unfold
Let’s paint a picture of how this epic showdown could play out. Imagine an open, barren wasteland—no hiding spots, just raw power meeting raw power.
Initial Engagement
Kurama, sensing an immense cursed energy signature, would likely charge first, driven by its primal instinct and immense power. Its roar would shake the very ground, and it would immediately unleash a volley of chakra-enhanced physical attacks—tail swipes, claw slashes, perhaps even a smaller Bijuudama to test the waters. Sukuna, ever the strategist, would likely observe, perhaps even tanking an initial hit to gauge Kurama’s physical power and chakra nature. He wouldn’t underestimate a beast of Kurama’s magnitude.
Sukuna, with his superior speed, would dance around Kurama’s massive physical attacks, perhaps even landing a few precise Cleave attacks to see how Kurama’s chakra cloak holds up. These initial slashes, adapting to Kurama’s immense resistance, would likely cause significant superficial damage, drawing blood and showing the beast that this opponent is far from ordinary. Kurama’s regeneration would kick in, but the sheer volume of Sukuna’s slashes would make full recovery difficult in a prolonged close-quarters fight.
Escalation: Bijuudama vs. Fire Arrow
Realizing physical attacks are too slow or ineffective against Sukuna’s agility and regeneration, Kurama would likely charge a full-power Bijuudama. The ground would rumble, and a swirling mass of destructive energy would form in its mouth. This is the moment Sukuna would need to respond with his own heavy artillery. He could counter with his Fire Arrow, creating a devastating explosion that would clash with the Bijuudama, potentially neutralizing it or causing a massive area-of-effect blast that damages both combatants. However, the Bijuudama’s raw destructive scale might still overwhelm the Fire Arrow, forcing Sukuna to use his agility or Reverse Cursed Technique to mitigate the damage.
My gut feeling? Sukuna wouldn’t just meet a Bijuudama head-on with a Fire Arrow if he didn’t have to. He’d likely aim to disrupt its charging or use his speed to get out of the immediate blast radius, or perhaps even surprise Kurama with a quick Domain Expansion while it’s focused on charging. The tactical advantage always rests with Sukuna here.
The Decisive Move: Malevolent Shrine
This is where the tide would turn. Sukuna’s strategic mind would identify that Kurama, for all its power, relies on traditional defenses and raw force. A massive, durable target with a clear, albeit powerful, attack pattern is precisely what Malevolent Shrine is designed to counter. As Kurama charges another Bijuudama or attempts a devastating physical attack, Sukuna would activate his Domain Expansion: Malevolent Shrine.
The moment the Domain manifests, Kurama would find itself caught in an inescapable, guaranteed-hit zone. Hundreds, perhaps thousands, of Dismantle and Cleave slashes would rain down upon its massive form simultaneously and continuously. Kurama’s chakra cloak, while incredibly durable, would be constantly adapting to these attacks, which are *guaranteed to hit*. There’s no dodging, no blocking, just constant, unavoidable damage. Cleave, specifically designed to bypass durability by adjusting its output, would be devastating.
Even with Kurama’s immense durability and chakra-based healing, the sheer volume and precision of Malevolent Shrine’s attacks would be too much. It’s not about one big hit; it’s about being continuously torn apart at a molecular level. This sustained, overwhelming damage would gradually wear down Kurama’s defenses, regardless of its chakra reserves. Its regeneration would struggle to keep up with the rate of destruction.
The Outcome
While Kurama’s Bijuudama remains an incredibly potent threat that could potentially one-shot Sukuna if it lands, Sukuna’s agility and, most importantly, his Domain Expansion provide him with a decisive edge. Kurama has no known counter for a guaranteed-hit attack that bypasses conventional defenses. Eventually, under the relentless, unavoidable assault of Malevolent Shrine, even the Nine-Tails would be carved into pieces. Sukuna’s regeneration would allow him to recover from any incidental damage from Kurama’s wider attacks, while Kurama has no comparable ability to counter Malevolent Shrine’s nature.
Factors Favoring Each Combatant
Let’s lay out the key advantages for each.
Factors Favoring 20-Finger Sukuna:
- Domain Expansion (Malevolent Shrine): The ultimate trump card. Its guaranteed-hit and open-barrier nature provides an unavoidable, continuous damage output that bypasses Kurama’s durability.
- Adaptive Slicing (Cleave): Specifically designed to penetrate resistant targets, meaning it will always be effective against Kurama’s chakra cloak.
- Superior Regeneration: Reverse Cursed Technique allows Sukuna to heal from fatal wounds, providing immense staying power.
- Tactical Acumen: Sukuna’s centuries of battle experience and cold, calculating mind make him an incredibly dangerous and adaptable opponent.
- Combat Speed & Agility: Sukuna is faster and more agile, making him harder to hit with Kurama’s larger, albeit powerful, attacks.
Factors Favoring Kurama (Full Power):
- Raw Destructive Power (Bijuudama): Capable of country-level destruction, a direct hit could incapacitate or severely injure Sukuna.
- Immense Chakra Reserves: Allows Kurama to fight for extended periods and continuously unleash powerful attacks.
- Sheer Size and Durability: Kurama’s massive form and chakra cloak make it incredibly resilient to conventional attacks.
- Area-of-Effect Capability: Its attacks can cover vast areas, potentially limiting Sukuna’s movement options.
Addressing Common Fan Arguments and Misconceptions
One common argument I often hear in these discussions is, “Kurama is too big, Sukuna’s attacks wouldn’t do anything!” And it’s a valid point on the surface. Kurama is gargantuan. But that’s where the nuance of Sukuna’s abilities comes in.
* **Size vs. Cleave:** Cleave isn’t just a fixed-power slash. It *adapts* to the target’s cursed energy resistance. This means against a target as large and durable as Kurama, Cleave wouldn’t just bounce off; it would scale up to cut more effectively. It’s not a matter of whether Sukuna *can* cut Kurama, but that his technique ensures he *will*.
* **Bijuudama vs. Sukuna’s speed/Domain:** Some argue a Bijuudama is too fast and large for Sukuna to dodge. While incredibly powerful, Sukuna has reacted to and dodged attacks from opponents with comparable speeds (e.g., Mahoraga). More importantly, Sukuna isn’t just relying on dodging. His Domain Expansion *guarantees* his attacks hit. A Bijuudama needs to be *aimed* and *landed*, whereas Malevolent Shrine just *happens* within its range. If Sukuna activates his Domain while Kurama is charging or just after firing, the continuous slashes would overwhelm Kurama before it could react or fire another.
* **Chakra vs. Cursed Energy:** This is the biggest hurdle. If chakra provided complete immunity to cursed energy, then Kurama would win by default. But as discussed, assuming a neutral interaction, Cursed Energy’s fundamental properties (like guaranteed hit and adaptive cutting) are just too powerful to be ignored.
My personal opinion, after dissecting their abilities, is that Sukuna’s power set, especially Malevolent Shrine, is uniquely suited to dismantle large, durable targets. Kurama is an engine of pure destruction, but it lacks the intricate, reality-bending techniques that Sukuna possesses. It’s like trying to put out a forest fire with a fire hose, versus using a precision laser to break down the fuel at a molecular level. Both are powerful, but one has a more tailored approach to *destroying* an entity rather than just *overpowering* it.
Conclusion: The King of Curses Reigns
After a deep dive into the formidable arsenals of both 20-finger Sukuna and Kurama, the scales, albeit narrowly, tip in favor of the King of Curses. While Kurama represents an almost insurmountable force of nature with its devastating Bijuudama and immense physical prowess, Sukuna’s unique abilities provide too many decisive advantages.
The key differentiator is Sukuna’s Domain Expansion, Malevolent Shrine. Its guaranteed-hit effect, coupled with the adaptive cutting power of Cleave, creates a scenario from which Kurama has no clear escape. It’s not a matter of durability when every attack is guaranteed to land and bypass conventional defenses. Kurama’s immense size and stamina, while impressive, become a liability within a Domain designed to continuously carve up everything in its vast radius. Sukuna’s incredible regeneration also means he can recover from the most powerful strikes Kurama might manage to land outside the Domain’s influence, whereas Kurama lacks a similar capability to counter the relentless, unavoidable assault of Sukuna’s true power.
In a neutral arena where both energy systems interact, Sukuna’s tactical genius, his precision-based lethal techniques, and most importantly, the absolute power of Malevolent Shrine, would ultimately lead to his victory over the mighty Nine-Tails. It would be a battle of epic proportions, shaking the very foundations of their shared hypothetical reality, but Sukuna’s mastery over his cursed energy and his unparalleled Domain would be the deciding factor.
Frequently Asked Questions About Sukuna vs. Kurama
How would Kurama’s chakra defenses interact with Sukuna’s Cursed Energy attacks?
This is a pivotal question for any cross-universe battle. Assuming a neutral ground where both energy systems can directly affect each other, Kurama’s chakra defenses, such as its chakra cloak and raw durability, would likely function as resistance against Sukuna’s Cursed Energy. However, Sukuna’s techniques are specifically designed to overcome such resistance. Cleave, for instance, adjusts its output based on the target’s cursed energy resistance, meaning it would continuously scale up to effectively cut through Kurama’s chakra-reinforced hide.
Moreover, Malevolent Shrine’s guaranteed-hit property means that these attacks wouldn’t be blocked or dodged; they would simply land. While Kurama’s chakra would undoubtedly cushion some blows, the sheer volume, continuous nature, and adaptive penetration of Sukuna’s slashes within his Domain would eventually overwhelm even the Nine-Tails’ immense defensive capabilities. It’s a battle of sustained, precise erosion against raw, brute force durability.
Could Kurama’s Bijuudama one-shot Sukuna before he activates his Domain?
Kurama’s Bijuudama is undeniably a cataclysmic force, capable of leveling vast landscapes and possessing immense speed. If a fully charged Bijuudama were to land directly on Sukuna, it could very well be a one-shot knockout, potentially vaporizing him. However, several factors mitigate this risk for Sukuna. First, Sukuna is incredibly fast and agile, capable of dodging or repositioning to avoid direct hits from large-scale attacks.
Second, Sukuna’s Reverse Cursed Technique provides rapid regeneration, meaning even if he were caught in the periphery of a blast and grievously wounded, he could likely heal. More crucially, Sukuna is a tactical genius. He would likely prioritize activating his Domain Expansion as soon as he perceives the threat of a full-power Bijuudama. Given that Domain Expansion can be cast in an instant, it’s highly probable Sukuna could deploy Malevolent Shrine before or as Kurama launches its most devastating attack, turning the tables entirely. The Bijuudama needs to be charged and aimed, offering a window for Sukuna to act decisively.
What if Sukuna’s Domain Expansion couldn’t affect a non-Jujutsu entity like Kurama?
If we strictly adhere to the lore that Cursed Energy and Domain Expansions *only* affect beings within the Jujutsu Kaisen universe, then the fight becomes fundamentally different, and arguably unfeasible as a direct comparison. In such a scenario, Sukuna’s primary winning condition (Malevolent Shrine) would be nullified. Without his guaranteed-hit attack, Sukuna would be forced to rely on his physical prowess, raw Cleave/Dismantle attacks, and Fire Arrow.
Against Kurama’s immense size, durability, and country-level Bijuudama, Sukuna would be at a severe disadvantage. While his adaptive slashes could still inflict damage, Kurama’s ability to constantly spam massive, destructive attacks would likely overwhelm Sukuna’s capacity to heal or dodge indefinitely. Without the Domain, Kurama would likely dominate through sheer destructive scale and resilience. However, for a meaningful cross-verse debate, the common assumption is that abilities would interact, otherwise, the premise of the fight itself is broken.
Would Kurama’s immense chakra reserves outlast Sukuna’s Cursed Energy?
Kurama’s chakra reserves are indeed depicted as virtually limitless, allowing it to maintain its immense power and unleash devastating attacks for prolonged periods. In a war of attrition where both combatants only had fixed, depletable energy pools, Kurama would undoubtedly have an advantage. However, Sukuna’s strength doesn’t purely rely on the *volume* of his cursed energy in the same way. His techniques are incredibly efficient, and his Domain Expansion is a finishing move, not a prolonged drain.
While Malevolent Shrine uses a significant amount of Cursed Energy, Sukuna’s reserves are also astronomical. The critical difference is that Malevolent Shrine is designed to *end* the fight quickly by overwhelming the opponent, rather than slowly draining them. Kurama would likely succumb to the continuous, unavoidable damage of the Domain long before Sukuna ran out of the Cursed Energy required to maintain it for the necessary duration. Furthermore, Sukuna’s Reverse Cursed Technique helps him recover from injuries without significant energy drain, allowing him to stay in the fight longer in terms of physical integrity.
