The Demon Slayer anime is approaching its conclusion, leading to increasing discussions among fans regarding various aspects of the series. With the manga’s final chapter released in May 2020, a deeper insight into the main antagonist, Kibutsuji Muzan, emerged, some of which remains unexplored in the anime adaptation.
One significant reveal from the manga is that Muzan is not just a typical human; he possesses an extraordinary physiology with seven hearts and five brains. This unusual anatomical structure has prompted fans to humorously criticize Muzan for his apparent lack of intelligence, despite having numerous brains. However, such critiques may stem from a misunderstanding of the functions these organs serve within the context of the narrative.

The Misunderstood Genius of Muzan Kibutsuji
In chapter 187, titled “Innocent Person,”Koyoharu Gotouge, the creator of Demon Slayer, unveils Muzan’s unique anatomy during a pivotal flashback involving Yoriichi Tsugikuni. Often since this revelation, fans have directed criticism at Muzan regarding his perceived irrational decisions, especially for someone purported to have superior intelligence.
Muzan’s notable decisions, such as executing the Lower Moon demons, sparing Tanjiro during their Asakusa encounter, and leaving the Kamado family’s remains for Tanjiro to find, have sparked debates among fans. Many dissect the potential alternatives he could have pursued, questioning why he, a character designed to be vastly intelligent with five brains, would make such imprudent choices.
While fans raise valid points linking Muzan’s actions to his supernatural brain count, the true purpose of his extra organs may have less to do with intellect and more to do with his combat capabilities, a nuance often overlooked by the audience.
These additional organs likely play a critical role in the execution of Muzan’s formidable Blood Demon Art. His unique ability, Biokinesis, grants him complete control over his anatomy, enabling him to create flesh whips from his limbs and even shapeshift. The multiple brains assist in enhancing coordination, facilitating movement precision after utilizing his signature abilities. Meanwhile, the numerous hearts contribute to his regenerative powers by maintaining effective blood circulation and providing crucial energy boosts, thereby fortifying his resilience against decapitation by Nichirin blades.
Conclusion: The Complexity of Kibutsuji Muzan
Although the series does not provide explicit definitions for the functions of Muzan’s multiple organs, the hypothesis regarding their roles offers a reasonable explanation grounded in the series’ facts. The portrayal of Muzan’s supposed “stupidity”serves as a compelling storytelling device—had he approached situations differently, the narrative could have shifted dramatically.
As fans look forward to the forthcoming Infinity Castle arc, the anime will delve deeper into Muzan’s powers and the looming confrontation against the Demon Slayers. Some teasers have already hinted at this epic showdown, promising to unveil more about the character as the story nears its climax.
