Does Tanjiro Become a Demon?
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.

When Does Tanjiro Become a Demon in the Manga?
Tanjiro becomes a demon right after Muzan’s defeat in Chapter 201 of the manga. This transformation is not shown in the anime yet, but it happens during the Infinity Castle arc. As Muzan dies, he injects his blood into Tanjiro’s near-dead body. In Chapter 202, Tanjiro Kamado awakens as a demon and briefly attacks his fellow demon slayers before regaining his senses later.
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 Demon Form
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.

Does Tanjiro become human again?
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 experienced 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.

Will Tanjiro Become a Demon in the Anime?
No, the anime has not shown that moment yet. But we are almost there. Tanjiro becomes a demon in Chapter 201 of the manga, right after Muzan is finally defeated. In his last breath, Muzan injects his blood into Tanjiro’s dying body. That is how Tanjiro turns into a demon for a short time. If you are only watching the anime, then this part is still missing. But not for long.
In 2025, Ufotable confirmed that the final arc will not be a TV season. Instead, they are turning it into a movie trilogy called Demon Slayer: Infinity Castle. This trilogy will cover everything from the start of the final battle to the very end of the story. That includes Tanjiro’s transformation into a demon.
The first movie is already announced. It will likely release in late 2025. If they follow the manga pacing, then Tanjiro’s demon form will appear in the second or third movie. Most fans believe it will come out sometime in 2026.
The studio has followed the manga very closely till now. So you can expect to see every scene—Tanjiro lying lifeless, his sudden awakening, and the moment where he attacks his friends without knowing who they are. That part is emotional, scary, and one of the biggest twists in the entire story.
We all know it is coming. You just have to wait a little more. Once that scene airs, Tanjiro’s demon form will shake the whole anime community.
Conclusion
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.
