What if Tanjiro's sword turns red?

In Demon Slayer: Kimetsu no Yaiba, Tanjiro's sword turning red is a significant and unique event that occurs during his battles, specifically during his fight against Muzan Kibutsuji. Here's what it means and why it’s so important:

The Significance of Tanjiro's Red Sword:

1. Sun Breathing: Tanjiro's sword turning red is linked to his ability to use Sun Breathing (also known as Hinokami Kagura, or "Dance of the Fire God"). This is the original form of all Breathing Techniques, and it is the key to defeating demons, particularly Muzan. When Tanjiro uses this technique, the sword turns red as a visual manifestation of the power of the Sun, which is the only thing that can destroy Muzan completely.

2. The Red Color: In Demon Slayer, swords that turn red are a rare occurrence. This is because Sun Breathing mimics the power of sunlight, and Muzan, being a demon, is highly sensitive to sunlight. The sword’s red color symbolizes the intense heat and power of the sun, which is what makes it capable of harming and eventually destroying demons.

3. Tanjiro’s Connection to the Sun: It’s revealed that Tanjiro’s family was connected to the Sun Breathing technique through the Dance of the Fire God. His father, Tanjuro Kamado, passed down this technique to Tanjiro. When Tanjiro uses Sun Breathing, his sword turns red, reflecting his ancestral connection to the power of the sun.

4. Symbolic Meaning: Tanjiro’s red sword is also symbolic of his role as the one who will end the reign of demons. It represents his growth as a warrior and his connection to his heritage. His red sword is a manifestation of hope and the ultimate weapon against Muzan, who had been terrorizing humanity for centuries.

What Would Happen if Tanjiro's Sword Turns Red?

If Tanjiro’s sword turns red:

• Increased Power: It would indicate that he is using the full power of Sun Breathing, making his strikes incredibly potent and capable of severely damaging or even destroying demons, especially high-ranking demons like Muzan.
• Possibly Defeating Muzan: In the final battle against Muzan, Tanjiro’s red sword was instrumental in wounding Muzan severely and weakening him. The sword turning red symbolizes the effectiveness of Sun Breathing and the potential to end Muzan's life.

What Happens to the Sword After It Turns Red?

In the Demon Slayer series, Tanjiro’s sword turns red due to his proficiency with Sun Breathing. The sword doesn't remain permanently red because the ability to generate such heat is linked to his mental and physical state. The red color only appears when Tanjiro is using Sun Breathing to its fullest extent.

Conclusion:

Tanjiro’s sword turning red signifies the powerful Sun Breathing technique he has inherited, which is crucial in the fight against demons, especially Muzan. It is a rare and powerful occurrence, symbolizing his strength, heritage, and the ultimate potential to defeat the demon king. If his sword turns red again in the future, it would likely mark a significant turning point in his battle, granting him the necessary power to confront formidable threats.
