Unmasking Kokushibo’s Slayer

Kokushibo’s end comes during a fierce battle, an encounter that could only be described as a high-stakes chess match with every move mattering. It’s a clash not just of physical prowess, but also of ideologies and determination. A fight that doesn’t simply ask who’s the strongest, but ultimately, who’s the most resolute.

The one who delivers the fatal blow to Kokushibo is none other than Gyomei Himejima, the Stone Hashira. Himejima is one of the most powerful characters in the Demon Slayer Corps, a group dedicated to hunting down and exterminating demons. His strength, combined with the spiritual power of his weapon, the Nichirin Axe, ultimately seals Kokushibo’s fate.

However, it’s important to note that Himejima wasn’t alone in this fight. He was supported by fellow Demon Slayers, Sanemi Shinazugawa, the Wind Hashira, Muichiro Tokito, the Mist Hashira, and Genya Shinazugawa, a Demon Slayer Corps member and Sanemi’s younger brother. However, despite their valiant efforts, Muichiro and Genya are unable to match Kokushibo’s power and tragically lose their lives in the battle.

The Deeper Meaning Behind The Fall Of Kokushibo

The death of Kokushibo in Demon Slayer isn’t just a critical plot point but also carries significant thematic weight. It’s a poignant moment that underscores the destructive consequences of unchecked ambition and the misguided pursuit of power.


Kokushibo, once a human, chose to become a demon out of a desire for immortality and strength. His untenable thirst for power led him down a path of destruction, causing him to lose his humanity in the most literal sense. His death at the hands of the Demon Slayers, especially Himejima, serves as a stark reminder of the values they champion: courage, compassion, and the sanctity of human life.

The way Kokushibo dies, regretting his choices and longing for the human connections he lost, adds a layer of tragedy to his character. It reminds viewers that he was once a person, with dreams and desires that were tragically twisted by his choices.


So, to answer the question: Who killed Kokushibo in Demon Slayer? It was Gyomei Himejima, with the help of Sanemi, Muichiro, and Genya Shinazugawa. Yet, this wasn’t simply a matter of who struck the last blow. Kokushibo’s demise reflects the culmination of his own actions and choices, a testament to the narrative’s exploration of humanity, morality, and the consequences of our decisions.

In the end, the death of Kokushibo serves as a powerful narrative device, a poignant moment that leaves a lasting impact on both the characters and viewers. It’s a testament to the rich storytelling of Demon Slayer, where every action has a consequence, and every character, no matter how powerful, has their weaknesses.
