The True Strength of Kento Nanami in Jujutsu Kaisen

Introduction: More Than Just a Salaryman

In the chaotic, cursed world of Jujutsu Kaisen, strength is often measured by flashy techniques, raw cursed energy, or larger-than-life personalities. But there’s one character who stands out for being calm, composed, and methodical—Kento Nanami.

Often referred to as the "salaryman sorcerer," Nanami is anything but average. Behind the suit and the no-nonsense demeanor lies a deeply powerful and respected Grade 1 Jujutsu Sorcerer. Whether it's his cursed technique, his sword, or his unwavering moral code, Nanami's presence in the story is unforgettable. His strength isn’t just physical—it's mental, emotional, and philosophical.

This article dives into the true strength of Kento Nanami in Jujutsu Kaisen, exploring his cursed technique, combat skills, weaponry, ideology, and what truly makes him one of the most compelling characters in the series.

Nanami’s Cursed Technique: Ratio Strikes with Ruthless Logic

At the heart of Nanami’s combat style lies his unique cursed technique: Ratio Technique (Ratio 7:3). This ability allows Nanami to divide his opponent's body into ten parts and find a weak point at a guaranteed 7:3 ratio. Once this point is identified, he can channel his cursed energy into that spot, striking with maximum impact regardless of the enemy's durability or defenses.

What makes this cursed technique so powerful in Jujutsu Kaisen is its precision. While others rely on brute force or unpredictable attacks, Nanami relies on math, structure, and inevitability. He doesn’t waste movement. Every strike is clean, calculated, and crushing.

In battle, the Ratio Technique allows him to take down curses far stronger than himself by exploiting these guaranteed weak points. When paired with his blade, the effectiveness of this technique makes Nanami one of the most surgical fighters in the series.

Nanami’s Weapon: The Binding Blade

Kento Nanami wields a blunt, cleaver-like weapon wrapped in bandages—visually simple, but devastating in action. It’s not the kind of blade that slices cleanly like a katana. Instead, it smashes, amplifying the impact of his cursed technique.

The blade is a perfect extension of Nanami’s style. Practical, no-nonsense, and brutally effective. The blunt edge complements his 7:3 ratio technique by landing crushing blows precisely where they’ll do the most damage.

He’s shown using it to lethal effect against curses during the vs. Mahito arc, as well as during his underground battles. Nanami doesn’t showboat or rely on flashiness. He uses a weapon that simply gets the job done, again and again.

Nanami’s Domain: Overtime

One of Nanami’s most fascinating personal traits is his “overtime” system. In line with his salaryman persona, Nanami limits his cursed energy output during regular hours. However, once his shift is technically “over,” he releases his full power. In this state, his cursed energy output increases dramatically, making him noticeably more powerful.

While this might seem comedic, it actually adds a lot of depth to Nanami’s character and technique. He’s a man who follows his own code. He treats sorcery like a job, which means he gives it everything when it’s required—but never more than what is necessary. When overtime hits, that’s when his serious strength kicks in.

This unique perspective on power and self-discipline highlights how different Nanami is from most of the other sorcerers in Jujutsu Kaisen. He’s not driven by glory, revenge, or fame. He simply does what needs to be done—and when it’s time to go all out, he doesn’t hold back.

Kento Nanami vs Mahito: A Showcase of Strength and Principle

Nanami’s battle against Mahito, one of the most twisted antagonists in Jujutsu Kaisen, is a defining moment for his character. Mahito, who manipulates souls and warps bodies into grotesque monsters, represents chaos, cruelty, and reckless abandon. Nanami, in contrast, represents discipline, order, and purpose.

The two clash not just in combat, but in philosophy. During their encounter, Nanami’s Ratio Technique proves incredibly effective against Mahito’s constantly morphing body. Unlike many others who panic in Mahito’s presence, Nanami keeps his cool and lands clean, powerful blows.

While Nanami ultimately doesn’t kill Mahito, the fight showcases his incredible strength, resilience, and mental fortitude. He faces death head-on, not with fear, but with resolve. Even when overpowered, he never backs down—and that alone is a mark of true strength.

Strength of Character: Stoic, Smart, and Human

Nanami’s physical abilities and cursed techniques are impressive, but what truly sets him apart in Jujutsu Kaisen is his character.

He left the Jujutsu world once, disillusioned by the emotional toll and the politics of the sorcerer world. Choosing a mundane life as a salaryman, he realized that office work was just another flavor of soul-sucking monotony. He returned to sorcery not for power or prestige, but because he realized it was the one place where he could genuinely make a difference.

This awareness makes him highly relatable. He’s not chasing greatness—he’s just trying to do the right thing in a deeply flawed world. He mentors Yuji Itadori not with empty encouragement, but with real-life wisdom and caution. He doesn’t lie to Yuji about the dangers of being a sorcerer, and that honesty earns him the respect of both characters and fans alike.

Nanami’s presence brings balance to the chaos of Jujutsu Kaisen. He is the voice of reason in a world of extremes, and that quiet, unshakeable strength is something few others possess.

Death and Legacy: Going Out Like a True Sorcerer

Kento Nanami’s final moments during the Shibuya Incident Arc hit fans hard. Wounded, broken, and exhausted, he still chooses to stand and fight. In his final act, he clears a path for Yuji, choosing to sacrifice himself so that the next generation has a chance to succeed.

His death is poetic. It encapsulates his entire belief system: stay calm, do your duty, and protect the next in line.

Even Mahito, in his own twisted way, acknowledges Nanami’s strength—both as a sorcerer and as a man. And while he dies, Nanami’s legacy continues to influence the emotional backbone of Jujutsu Kaisen. His lessons stick with Yuji. His strength inspires others. And his name remains one of the most respected in the fandom.

Final Thoughts

The true strength of Kento Nanami in Jujutsu Kaisen lies not just in his Ratio Technique or his destructive blade—but in his quiet resilience, his grounded worldview, and his unwavering sense of responsibility. He doesn’t seek the spotlight. He doesn’t chase titles. But in every moment he’s on screen, he commands respect.

Nanami is proof that real strength isn’t loud. Sometimes, it’s quiet, calculated, and consistent. And that’s exactly why Kento Nanami will always be one of the greatest characters in Jujutsu Kaisen.
