Nanami Cursed Technique: Explained with Manga Insights

In the complex world of Jujutsu Kaisen, Nanami Kento has embodied calculated precision. This Grade 1 sorcerer has captured fans’ attention not only for his stoic attitude and work ethic but also for his uniquely analytical cursed technique. Unlike flashy abilities that dominate the series, Nanami’s technique reflects his analytical personality that is effective, precise, and devastatingly efficient when properly applied.

What Is Nanami’s Cursed Technique?

Nanami Kento’s cursed technique is officially called the Ratio Technique, sometimes referred to as 7:3. This technique allows Nanami to identify critical weak points on any target—whether it’s a curse or another sorcerer. Unlike other techniques that rely on overwhelming force, Nanami’s cursed technique embodies surgical precision.

The core principle behind Nanami’s cursed technique is mathematical in nature. By dividing any object or body into sections using the ratio of 7:3, Nanami can locate specific weak points that exist exactly at these proportional divisions. When struck with precision, these weak points yield significantly amplified damage—about 2.5 times the normal impact.

This makes what is Nanami’s cursed technique particularly unique: it doesn’t grant him spectacular visual powers or enormous energy attacks, but rather enhances his analytical abilities and precision striking.

How Nanami’s Ratio Technique Works in Close Combat

Nanami’s cursed technique activates through a combination of his cursed energy manipulation and his analytical mind. The process works in three key phases:

1. Analysis: Nanami observes his target and mentally divides it using the 7:3 ratio
2. Identification: The weak points appear to Nanami as a glowing cross or “+” symbol
3. Execution: He delivers a precise, concentrated strike with his weapon of choice—typically his blunt sword

What makes Nanami’s cursed technique particularly effective in combat is its versatility in close quarters. As a former salaryman-turned-jujutsu sorcerer, Nanami applies corporate efficiency to battle. He doesn’t waste movements or cursed energy, making each strike count.

In enclosed spaces where enemies can’t easily escape, Nanami can systematically identify and target weak points with brutal efficiency. His technique complements his fighting style—methodical, precise, and devastatingly effective when properly executed.

Nanami vs. Mahito: Ratio Technique in Action

One of the most impressive presentations of Nanami Kento’s cursed technique comes during his battle with the special grade curse Mahito. This battle showcases not only the power of the Ratio Technique but also Nanami’s tactical brilliance.

During this fight, Mahito’s ability to manipulate his own body initially seems to render Nanami’s technique less effective. However, Nanami adapts by:

• Rapidly identifying new weak points as Mahito reshapes himself
• Using his technique to find the location of Mahito’s soul
• Delivering devastating blows that force Mahito to reconsider his strategy

What’s particularly notable is how Nanami combines his cursed technique with his analytical thinking. When Mahito believes he’s countered the Ratio Technique by understanding the 7:3 division, Nanami reveals he can apply multiple ratios simultaneously, identifying weak points at 7:3, 5:5, and other proportions.

This battle demonstrates what does Nanami’s cursed technique do at its fullest potential—not just amplifying damage but adapting to seemingly impossible circumstances through calculated precision.

Limitations and Strengths of Nanami’s Cursed Technique

While powerful, Nanami’s cursed technique has clear parameters that define when it excels and when it struggles:

Strengths:

• Precision damage: The ability to inflict 2.5x damage at weak points
• Tactical versatility: Works against any physical target
• Efficiency: Requires relatively low cursed energy expenditure compared to more flashy techniques
• Complementary to skill: Benefits from Nanami’s already exceptional combat abilities

Limitations:

• Range restriction: Primarily effective at close range
• Physical contact required: Must physically strike the identified weak points
• Complexity against moving targets: Requires recalculation against highly mobile enemies
• Cursed energy drain: Extended use over time gradually depletes stamina

What makes Nanami’s cursed technique particularly interesting is how these limitations shape his fighting style. Unlike younger sorcerers who might rely on overwhelming power, Nanami approaches each battle with calculated efficiency—striking only when necessary and maximizing damage output through perfect execution.

How Nanami’s Technique Reflects His Personality

Nanami Kento’s cursed technique serves as a perfect reflection of his character. As a former salaryman who views jujutsu sorcery as “just another job,” his ability embodies:

• Efficiency: No wasted movement or energy
• Precision: Calculated strikes rather than wild attacks
• Analysis: Careful observation before action
• Structure: Finding order even in chaotic battle situations

The 7:3 ratio itself symbolizes Nanami’s work philosophy. In one memorable scene, he explains to Yuji that life should be divided into a 7:3 ratio—with 7 parts being work and 3 parts being personal time. This same proportional thinking carries into his combat style.

Unlike techniques that evolve dramatically through emotional states (like Gojo’s Limitless or Megumi’s Ten Shadows), Nanami’s technique remains consistent—much like his steadfast personality. This consistency makes Nanami Kento’s cursed technique one of the most reliable abilities in the series.

Legacy and Impact in the Jujutsu Kaisen Universe

Nanami’s methodical approach to combat and his cursed technique have left a lasting impression on both characters within the series and fans. His mentorship of Yuji Itadori demonstrates how technical precision can sometimes triumph over raw power—a lesson that shapes Yuji’s development.

Within the power scaling of Jujutsu Kaisen, Nanami’s technique demonstrates how a seemingly simple ability can become dangerous through mastery and tactical application. While not as showy as Domain Expansions or inherited techniques, the Ratio Technique exemplifies the series’ theme that understanding your own strengths and limitations is crucial to success.

For newer jujutsu sorcerers, Nanami’s technique represents the importance of analytical thinking in battle and it’s something that saves lives when confronting unpredictable cursed spirits.
