In the world of Demon Slayer, death is not just an end but a crucial part of the story that drives characters forward and reshapes the course of the battle. Some deaths bring deep sorrow to fans, others become iconic, and some completely change the story’s direction.
Here are the 7 most impactful deaths in the Demon Slayer manga:
7. Mitsuri Kanroji

Mitsuri Kanroji’s death is one of the most emotional moments in the series. After a long battle with Muzan, she was gravely wounded. Facing death, she was held by Obanai Iguro, the Serpent Hashira. Overwhelmed by emotion, they confessed their love for each other.
Despite the tragic circumstances, they promised to be reborn and meet again in another life. They died shortly after. Mitsuri’s dream of becoming Obanai’s bride didn’t come true in this life, but they kept their promise and reunited after reincarnation.
6. Tamayo

Tamayo worked with Muzan centuries ago but, after witnessing the battle between the Demon King and Yoriichi, she hoped to break free from Muzan’s influence and end his reign.
During the final battle, Tamayo injected Kibutsuji with a drug that could transform him back into a human. She bravely followed Muzan after Kagaya’s self-sacrifice, using a massive explosion to corner him.
Facing Muzan came at a great cost. Tamayo lost her life during the Infinity Castle battle. Still, her courageous efforts were key to ultimately stopping Muzan Kibutsuji.
5. Muichiro Tokito

Muichiro Tokito was one of the most talented swordsmen of the Taisho era. He became a Hashira just two months after picking up a sword and fought in many major battles. His greatest fight was against Kokushibo, alongside Gyomei, Genya, and Sanemi.
Despite being severely wounded early on, Tokito showed extraordinary strength and fought to the very end. He played a crucial role in defeating Kokushibo. However, his injuries were too severe, and he lost too much blood. He passed away shortly after the battle, leaving behind the legacy of one of the greatest swordsmen ever.
4. Shinobu Kocho

After her sister was killed by an Upper Moon demon, Shinobu Kocho harbored a deep desire for revenge. Before the final battle, she devised a cunning plan to face the demon who killed her sister. In the Infinity Castle arc, Kocho finally confronted Doma and immediately recognized him as the demon she had been hunting.
Knowing she couldn’t defeat Doma in a one-on-one fight, she spent months concentrating a poison from wisteria flowers in her body. When she fought Doma, the battle was one-sided, and she barely harmed him. But as she hoped, Doma absorbed her, allowing the poison to enter his body. Shinobu’s brave death gave Inosuke and Kanao the chance to fight and ultimately defeat the Upper Moon Two.
3. Yoriichi Tsugikuni

Yoriichi Tsugikuni was one of the strongest characters in Demon Slayer. However, his death did not come in battle but from old age. In his final moments, he challenged his brother Kokushibo, who had become a demon. Even in old age, Yoriichi was too fast for the demon and might have won if not for his natural death.
His death had far-reaching consequences, allowing Muzan to terrorize the world for several more centuries.
2. Kagaya Ubuyashiki

Kagaya Ubuyashiki led the Demon Slayer Corps during one of its toughest times. He gathered a legendary team of Hashira who later defeated Muzan and his minions.
But Kagaya’s death was impactful not just because of his achievements. His self-sacrifice sparked the flame that ultimately defeated Muzan Kibutsuji. Without his foresight and insight, the Demon Slayer Corps would never have overcome the Demon King.
1. Kyojuro Rengoku

Kyojuro Rengoku, the Flame Hashira, was a fearless warrior willing to sacrifice himself for the greater good. When he, Tanjiro, and friends were cornered by Akaza after the battle with Enmu, Rengoku took on the responsibility of fighting the Upper Moon Three.
Despite the overwhelming power gap, Rengoku surprised Akaza with his relentless courage. Akaza even felt Rengoku was too special to die as a human and offered him a place among the Twelve Kizuki.
Rengoku refused, holding onto his humanity and fighting to the end for the greater good. His death shocked fans, as Hashira were seen as nearly invincible. His selfless sacrifice had profound effects and influenced the final battle between the Demon Slayer Corps and Muzan’s forces.
