In the dark and complex universe of Jujutsu Kaisen, few weapons stand out as much as the soul split katana. Unlike most cursed tools, this blade doesn’t rely on cursed energy—it cuts through what most others cannot: the soul itself. It's a rare cursed weapon, but even rarer are those who can wield it effectively. Passed from Toji Fushiguro to Maki Zenin, the soul split katana represents not just strength, but defiance, legacy, and evolution.
What Makes the Soul Split Katana So Unique?
At its core, the soul split katana is a cursed tool with the extraordinary ability to bypass physical durability, cursed techniques, and barriers. It does this by targeting the soul directly. That means even the strongest regenerative abilities or defensive techniques are useless if the blade strikes true. The only way to counter such a weapon is to perceive one’s soul—and even then, healing is difficult if not impossible.
What sets it apart from other cursed weapons is the requirement to truly see the soul. This ability is rare, which is why very few can unleash the katana's full potential. In the wrong hands, it's just another sword. In the right hands, it's an unstoppable force.
Toji Fushiguro: The Sorcerer Killer
Toji Fushiguro is the first known wielder of the soul split katana. Born into the prestigious Zenin clan without any cursed energy, he was treated as a disgrace and cast aside. Yet this lack of cursed energy led to him receiving the Heavenly Restriction—a condition that drastically boosted his physical abilities and senses.
Without cursed techniques, Toji relied on pure strength, speed, and strategy. He became a feared assassin among sorcerers, known as the Sorcerer Killer. The soul split katana was his most dangerous weapon, and in his hands, it became legendary. He used it to kill powerful sorcerers and cursed spirits alike, slicing through opponents who believed themselves invincible behind layers of cursed energy.
Perhaps the most significant display of the sword’s power was during his mission to assassinate Riko Amanai. With a single strike, Toji cut through her and any defenses protecting her. Even Satoru Gojo, the most powerful sorcerer in the series, was caught off guard by Toji’s skills and the katana’s soul-slashing capabilities.
A New Generation: Maki Zenin Rises
The soul split katana wouldn’t disappear with Toji’s death. Instead, its legacy was reborn through Maki Zenin—another outcast of the Zenin clan. Like Toji, Maki was born with no cursed energy and was rejected by her own family. But unlike Toji, she chose to stay and fight from within.
After the events of the Shibuya Incident, Maki faced a turning point. Her sister Mai, during a moment of ultimate sacrifice, used her cursed technique to forge a replica of the soul split katana and died in the process. This moment awakened Maki’s true potential. Now free from her physical limitations and wielding the same kind of cursed blade Toji once used, she began carving her own legend.
A Weapon of Vengeance
With the soul split katana in hand, Maki returned to the Zenin clan not as a disgraced daughter but as an unstoppable force. She cut down the elders and warriors who had once ridiculed her, showing no mercy. Her movements were clean, her strikes precise, and her vengeance absolute.
But Maki’s use of the soul split katana wasn’t just about revenge. It was about reclaiming her identity, proving her worth, and carrying on the will of her sister. The sword became not just a weapon of war but a symbol of rebellion. Maki didn’t need cursed energy to stand shoulder-to-shoulder with elite sorcerers—just like Toji, she proved that raw will, skill, and the right tool were enough.
Battles That Defined the Blade
In one of the most intense arcs following Shibuya, Maki engages in combat with the reincarnated spirit Naoya Zenin. Although her attacks initially couldn’t kill him, another wielder of the katana—Hagane Daido—showed how to unlock the blade’s full potential. By truly understanding how to cut the soul, Daido was able to destroy Naoya completely.
Later, Maki herself reaches that understanding. In her final battle with Naoya, she lands a strike that splits his body and soul cleanly in two. It is the ultimate testament to how much she has grown—not just in skill, but in spiritual perception.
More Than Just a Sword
The soul split katana is more than a blade. It’s an idea. A philosophy that strength doesn’t always lie in cursed techniques or energy levels. Sometimes, it lies in understanding the self, the enemy, and the essence of battle.
Both Toji and Maki were outcasts in a world obsessed with cursed energy. Yet both of them proved that they could rise to the top with sheer discipline, skill, and the right weapon. The soul split katana, in their hands, became a weapon of revolution.
The Legacy Continues
As Jujutsu Kaisen progresses, the soul split katana continues to play a major role. Fans have come to associate it with characters who refuse to conform, who rise from rejection and redefine what it means to be powerful. Whether in the hands of Toji, Maki, or someone new, the katana remains a weapon that challenges the norms of the jujutsu world.
Its story is a story of rebellion. It belongs to those who were told they were not enough. And every time it strikes, it reminds the world that cursed energy alone does not make a warrior.
