Two power systems. Two fandoms. One argument that never dies.
Haki vs Cursed Energy has been the most debated topic in anime right now, and we’re finally settling it for good. Here at Shonen Vortex, we’ve spent months tracking both series side by side, breaking down how Gojo’s Infinity works, analysing the One Piece power system’s deepest secrets, and watching the Elbaf arc unfold in real time.
The answer isn’t what most fans expect.
As of 2026, both One Piece and Jujutsu Kaisen are in their most pivotal arcs ever. The stakes for understanding these systems have never been higher.
What Are These Two Power Systems?
Before we argue, we need to define. A lot of fans online skip this step and that’s why the debate never goes anywhere.
Cursed Energy, in JJK, is negative emotional energy produced by all living beings. Sorcerers learn to weaponise it. At its peak, it produces Domain Expansions that create unavoidable hit zones, reality-bending barriers, and near-instant kills.
Haki is the manifestation of a user’s willpower and spirit. It exists in three core forms: Observation, Armament, and Conqueror’s. According to the One Piece wiki and series lore, only a rare fraction of the world’s population can use all three.
Both systems are invisible forces rooted in inner strength. But they work in completely different ways.
How Haki Actually Works
Haki is willpower made physical. The stronger your spirit, the stronger your Haki.
Armament Haki hardens the body and can bypass Devil Fruit defenses. Observation Haki lets elite users see slightly into the future. Conqueror’s Haki, which Shanks uses at an almost god-level, can knock out weaker opponents just by existing in the same space.
The key mechanic? Haki scales with willpower and battle experience. There is no ceiling anyone has found yet.
Right now in the Elbaf arc, we’re seeing Haki pushed into territory we’ve never seen before. Shanks, Loki, and the giants are redefining what the system can do.
Here’s what makes Haki unique as a system:
- It requires no special biology or cursed womb to awaken
- It can be trained infinitely with no known upper limit
- Advanced Conqueror’s Haki coats weapons and multiplies attack power exponentially
- It passively operates even during unconscious moments for elite users
- Blackbeard’s unusual relationship with Haki proves the system has exceptions that still aren’t fully understood
- Future Sight (advanced Observation) has beaten opponents who should have been untouchable
How Cursed Energy Actually Works
Cursed Energy is darker, more technical, and frankly more terrifying in its upper limits.
Every human produces it through fear and negative emotion. Sorcerers are born with the ability to control it. But the full JJK power system goes much deeper than most fans realise.
The real game-changer is Reverse Cursed Technique. By multiplying negative energy by itself, users create positive energy that heals, regenerates, and powers the most advanced techniques. This is how Gojo maintained his Infinity at all times without burning out. It’s how Sukuna’s Malevolent Shrine became the most feared Domain in the series.
According to a 2024 analysis by CBR, Gojo’s Six Eyes allowed him to process Cursed Energy at near-zero cost, making him mathematically undefeatable in conventional combat.
The ceiling for Cursed Energy is a Domain Expansion. All Domain Expansions ranked show just how wide the gap is between average and elite sorcerers. Inside a Domain, hits are guaranteed. There is no dodging. There is no blocking with willpower alone.
What makes Cursed Energy unique:
- It is produced passively by every human on Earth
- Technique diversity is almost unlimited, each sorcerer has a unique ability
- Mahoraga’s adaptation ability makes it the only entity shown to adapt to and overcome any technique
- Domain Expansions create enclosed realities where the user’s technique auto-hits
- Yuta’s triple domain proved even Domains can be layered and subverted at the highest level
- Special Grade sorcerers like Yuta Okkotsu can copy and store any technique indefinitely
Head-to-Head: The Real Comparison
| Category | Haki | Cursed Energy |
|---|---|---|
| Accessibility | Anyone can awaken it | Requires sorcerer birth or lineage |
| Upper limit | Theoretically infinite | Capped by body’s output and technique |
| Speed ceiling | Observation grants future sight | Six Eyes grants near-zero cost processing |
| Best defence | Advanced Armament / CoC coating | Gojo’s Infinity (auto-reject everything) |
| Best offence | CoC-infused strikes | Domain Expansion (guaranteed hit) |
| Adaptability | Experience and willpower training | Mahoraga-level adaptation |
| Counter potential | Stronger Haki beats weaker Haki | Domains can be countered by domains |
The honest read? Haki is more democratic. Cursed Energy is more decisive at the top.
Which System Produces Stronger Fighters?
This is where it gets real.
According to a 2023 Crunchyroll audience survey, Gojo Satoru was voted the most popular anime character globally. Not just in JJK. Globally. That tells you something about the ceiling Cursed Energy creates in the public imagination.
But peak Haki users like Shanks, and potentially Loki in the Elbaf arc, are doing things that look just as untouchable. Shamrock and the twin mysteries around Shanks suggest One Piece is building toward a Haki ceiling we haven’t seen yet.
The case for Cursed Energy producing stronger individual fighters:
- Domain Expansions guarantee hits with no counter except a stronger Domain
- Sukuna in his true form dismantled multiple Special Grades simultaneously
- Reverse Cursed Technique allows full body regeneration mid-fight
- The Six Eyes + Infinity combination created a sorcerer who was statistically invincible
- Kenjaku survived for over a thousand years by hijacking bodies using Cursed Technique alone
The case for Haki:
- No biological requirement means the talent pool is infinite
- Conqueror’s Haki can incapacitate crowds passively
- Future Sight makes physical combat nearly impossible to win
- Haki scales with growth, never plateauing
What Fans Keep Getting Wrong
In practice, most of this debate falls apart because people compare the wrong tiers.
The mistake most fans make is comparing mid-tier Haki users to top-tier sorcerers. Or comparing a Special Grade sorcerer to a regular Haki user who hasn’t awakened Conqueror’s. That’s not a power system argument. That’s just a bad matchup.
After tracking both series closely here at Shonen Vortex, we think the real conclusion is this: Cursed Energy has a more defined and terrifying peak, but Haki has a wider and more accessible base. The systems are built for different narrative purposes.
Is Gojo actually the strongest sorcerer in the JJK universe? Probably yes, for now. Is Yuta now closing that gap in Season 3? The debate is very much alive.
And on the Haki side, the Elbaf arc secrets episode 3 revealed suggest we’re not even close to seeing the ceiling yet.
The Verdict
Cursed Energy wins at the absolute peak. A Domain Expansion from a Special Grade sorcerer is the single most decisive finishing move in either universe.
But Haki wins the long game. It scales without limit, requires no special birth, and the best Haki users keep getting stronger with no ceiling in sight.
Both systems are masterclasses in power system design. That’s why we’re still arguing about them in 2026.
