Top 10 Demon Slayer Fan Theories That Are Crazy Yet Plausible

Demon Slayer fan theories are even crazier that the show itself. Demon Slayer: Kimetsu no Yaiba has captured the hearts of fans with its thrilling story and captivating characters. 2023 was blessed with the Swordsmith Village Arc and it surely blew our minds. We will have to wait for the Hashira Training Arc now which is the difficult part. Can’t they just release everything at once? Sadly, that can’t happen. Now that the Fourth Arc of the series has reached its finale, here are ten intriguing Demon Slayer fan theories that have emerged surrounding the series:

  1. Muzan’s Hidden Immortality: Some fans speculate that Muzan, the main antagonist, possesses a hidden form of immortality that allows him to transfer his consciousness to another body, ensuring his survival and persistence throughout history.


2. Nezuko’s True Power: There is a theory that Nezuko, the protagonist Tanjiro’s sister who was turned into a demon, has yet to fully tap into her dormant powers. Fans speculate that she possesses unique abilities that could play a crucial role in the ultimate battle against Muzan.

3. Tanjiro’s Ancestral Connection: Fans speculate that Tanjiro’s lineage may hold a deeper connection to the Demon Slayer Corps and the origins of demons. Some theories suggest that his family history could uncover hidden secrets or ancient techniques.

4. Kanao’s Past: Kanao, one of Tanjiro’s allies, has a mysterious past that is yet to be fully explored. Fans theorize that her backstory holds significant importance, potentially revealing hidden connections to other characters or unexpected plot twists.

5. The Twelve Demon Moons’ Origins: The origins of the Twelve Demon Moons, Muzan’s most powerful subordinates, remain shrouded in mystery. Fans speculate on their past lives, potential connections to the human world, or the circumstances that led them to become demons.

6. Tanjiro’s True Potential: As the series progresses, fans theorize that Tanjiro’s innate abilities and his unwavering determination will lead him to unlock an extraordinary power or achieve a transformation that surpasses his current capabilities.


7. The Role of the Hashira: Some fans speculate on the possibility of a deeper conspiracy surrounding the Hashira, the elite Demon Slayer swordsmen. Theories suggest hidden agendas, conflicting loyalties, or even undercover members within their ranks. Wouldn’t that be so cool!

8. Muzan’s Weakness: Muzan’s seemingly invincible nature has left fans speculating about possible weaknesses that could be exploited in the final battle. Theories range from sunlight-based vulnerabilities to a particular sword technique that could be his downfall. But this is one of the weakest Demon Slayer Fan Theories as far as stating the obvious is concerned.

9. The Connection Between Yoriichi and Tanjiro: Yoriichi, a legendary Demon Slayer from the past, shares a striking resemblance to Tanjiro. Fans theorize that there may be a familial connection or a deeper link between the two, potentially influencing Tanjiro’s destiny. You might have noticed this in the Swordsmith Village Arc.

10. A Bittersweet Ending: Given the intense and emotionally charged nature of the series, fans speculate that the conclusion may not be entirely victorious. Theories suggest that sacrifices or tragic outcomes may be necessary to ultimately achieve peace. Don’t we just love animes that have such endings?


These Demon Slayer fan theories demonstrate the passion and engagement of the Demon Slayer fandom, as fans eagerly speculate and theorize about the intricate details of the story and its characters. While some Demon Slayer fan theories may prove accurate, others may simply be imaginative interpretations that add to the excitement and anticipation surrounding the series. You know how crazy people can get on Reddit sometimes.
