Main Characters Who Fought Muzan Kibutsuji
Tanjiro Kamado is the primary protagonist who directly fought Muzan Kibutsuji across the final arcs of the Demon Slayer series. His journey from a coal seller to a Hashira-level swordsman centers on avenging his family and defeating the Demon King through relentless combat and Sun Breathing techniques. Nezuko Kamado, his demon sister, plays a critical support role by resisting Muzan's control and aiding the final battle with her unique Blood Demon Art. The Kamado siblings represent the core human resistance against Muzan's centuries-long reign of terror.
Giyu Tomioka, the Water Hashira, was one of the first Demon Slayers to encounter Muzan and survived their initial confrontation. His role expanded significantly as he trained Tanjiro and coordinated the final operations against the Demon King serving as a tactical leader within the Demon Slayer Corps. Shinobu Kocho, the Insect Hashira, also fought Muzan indirectly by developing the Wisteria poison strategy used against him. Her sister Kanae's death at Muzan's hands motivated her long-term mission to gather intelligence and build the coalition that ultimately challenged the Demon King.
The Final Battle Participants and Strategies
The final confrontation against Muzan involved all remaining Hashira, including Kyojuro Rengoku, Tengen Uzui, Mitsuri Kanroji, and Muichiro Tokito, who sacrificed themselves to weaken the Demon King during the Infinity Castle arc and the Sunrise Countdown arc. Their collective efforts created the opening for Tanjiro to land the decisive blow, with each Hashira contributing unique combat abilities and Blood Demon Arts. The battle strategy relied on Yushiro's medical support, Tamayo's demon-specific research, and the coordinated use of Nichirin blades infused with Sun Breathing rhythms.
Muzan Kibutsuji himself deployed his most powerful demons, including the Upper Rank demons, to defend against the assault and delay the Demon Slayers during the critical final hours before dawn. His ability to split his body into thousands of cells and regenerate instantly forced the fighters to combine their efforts into a simultaneous multi-pronged attack. The outcome hinged on Tanjiro achieving the Transparent World perception and utilizing the Hinokami Kagura to deliver a lethal strike that permanently destroyed Muzan's core.
Outcomes and Legacy of the Fight Against Muzan
