In the Demon Slayer manga, Tanjiro does experience a period of being a demon, but it is not a long-lasting change. After the climactic final battle against the formidable antagonist, Muzan Kibutsuji, it becomes apparent that Muzan is on the verge of death.


Desperate to cling to existence, Muzan attempts to ensure his survival by passing on his blood to Tanjiro, thereby turning him into a demon. Following the intense battle, Tanjiro finds himself in a critical condition, teetering on the edge between life and death. In this vulnerable state, he undergoes the transformation into a demon.

The repercussions of this transformation are remarkable, as Tanjiro gains extraordinary strength and speed, surpassing the capabilities of a mere human. Not only that, he acquires the ability to regenerate from injuries that would typically prove fatal to a human.

Tanjiro’s transformation into a demon gives rise to his awe-inspiring demon form which is referred to as Demon King Tanjiro. This monstrous incarnation of our beloved protagonist showcases an incredible display of strength and abilities, leaving fans astounded.


The reason behind the tremendous power of Demon King Tanjiro lies in his background as a skilled demon slayer before his transformation. Tanjiro had already honed his combat skills and mastered the art of the sun breathing technique, widely recognized as the strongest breathing technique among demon slayers.

The combination of Tanjiro’s expertise as a demon slayer and the potent sun-breathing technique amplifies his abilities to extraordinary levels. As Demon King Tanjiro, he becomes a force to be reckoned with, possessing immense physical strength that surpasses ordinary demons.

In addition to his exceptional strength, “Demon King Tanjiro” retains his knowledge of combat techniques and strategic thinking, further enhancing his prowess in battle.

Is Demon King Tanjiro stranger than Muzan Kibutsuji?

Demon King Tanjiro

When comparing Demon King Tanjiro to the formidable antagonist, Muzan Kibutsuji, it is important to consider their backgrounds and experiences. In the Demon Slayer manga, Demon King Tanjiro is portrayed in his initial stage as a demon, having not consumed a single human. On the contrary, Muzan Kibutsuji had a long and dark history, engaging in countless battles and devouring thousands of humans to sustain his existence.

In terms of sheer longevity and experience, Muzan Kibutsuji would undoubtedly surpass Demon King Tanjiro. With his extended lifespan and accumulated strength, Muzan holds a significant advantage in terms of raw power and knowledge of the demon world.

However, it is crucial to recognize the untapped potential within Demon King Tanjiro. If given sufficient time, perhaps 10 or 20 years to grow and fully comprehend his newfound powers, he could surpass even Muzan Kibutsuji. Demon King Tanjiro possesses an incredibly terrifying potential as he possesses both the strength of the demon king (Muzan Kibutsuji) and the prowess of the strongest demon slayer Yoriichi.

With this combination of powers, Demon King Tanjiro has the capability to become an unmatched force in the Demon Slayer universe. The growth and understanding of his abilities could propel him to surpass not only Muzan Kibutsuji but also renowned figures like Yoriichi, the legendary demon slayer.

Did Tanjiro Die In The End?

No, Tanjiro did not die in the Demon Slayer manga. After his intense battle with Muzan, Tanjiro was gravely injured and on the verge of death. However, instead of dying, his transformation into a demon actually helped him recover from his injuries.

While in his demon form, Tanjiro was able to heal and regain his strength. But later, with the help of his friend Kanao, he managed to become human again. This was a significant moment for Tanjiro, as he reclaimed his original human identity.

In the final moments of the series, we see Tanjiro’s descendant living a happy life. They continue the legacy of the demon slayers by performing the Hinogami Kagura, a dance dedicated to honoring the brave demon slayers who fought alongside Tanjiro. This ending shows that Tanjiro not only survived his challenging journey but also created a better world for future generations

Does Tanjiro become human again?

Demon King Tanjiro

Yes, Tanjiro does become human again in the Demon Slayer manga. After his transformation into a demon, several factors contribute to his return to his human state.

Once Tanjiro turns back into a human, his sister Nezuko still has antibodies in her blood from the medicine that helped control her demon instincts. These antibodies, combined with a cure given by Kanao, help reverse Tanjiro’s demonization.

Interestingly, Nezuko, who was a demon for a longer time, successfully becomes human again without any issues. However, the same cannot be said for Tanjiro.

Even though Tanjiro was a demon for only a few minutes, he experiences lasting effects. He loses vision in one eye and his left arm doesn’t function properly anymore.

These physical challenges serve as reminders of Tanjiro’s time as a demon and the sacrifices he made.

The fate of Tanjiro Kamado in the Demon Slayer series is a journey filled with both trials and triumphs. While he undergoes a transformative experience as a demon, he ultimately regains his humanity with the help of Nezuko’s antibodies and Kanao’s cure. Tanjiro’s return to being human, however, comes at a cost, as he now faces permanent blindness in one eye and the impairment of his left arm.

As the series concludes, we catch a glimpse of Tanjiro’s descendant, living a joyful life and carrying on the legacy of the demon slayers. This serves as a testament to the enduring impact Tanjiro and his fellow slayers had on the world, even after their battles concluded.
