Why Is Tanjiro's Sword Black and Not Red?

'Demon Slayer' (Kimetsu no Yaiba) is a widely popular anime where each character’s sword is not just a weapon but a symbol of their power and destiny. Tanjiro’s sword is particularly unique—it is a black Nichirin sword, unlike the red swords, blue swords, and other colors seen among Demon Slayers. So, why is Tanjiro’s sword black? This question has intrigued many fans. Let’s explore the deeper meaning behind Tanjiro’s sword and his journey.

Tanjiro’s Sword and the Legend of Nichirin Blades

In the world of Demon Slayer, Nichirin blades are special swords used by Demon Slayer Corps members to effectively slay demons. The color of a Nichirin sword usually corresponds to the user’s Breathing Style. For example, the Flame Hashira’s sword is red, symbolizing Flame Breathing, while the Water Hashira’s sword is blue, representing Water Breathing. However, Tanjiro’s sword turns an extremely rare black color, and the anime does not provide a clear explanation for this, leaving fans curious about its significance.

Tanjiro’s Black Sword and Its Connection to Sun Breathing

Although Tanjiro initially uses Water Breathing, his sword is black. As the story progresses, his black sword hints at his connection to Sun Breathing, the most powerful and possibly the original Breathing Style. Sun Breathing is considered the foundation of all other breathing techniques, and Tanjiro’s black Nichirin sword is believed to be a sign of his inheritance of this ancient style. This suggests that Tanjiro is not just any swordsman but a potential successor to the legendary Sun Breathing technique.

Did Tanjiro Get Yoriichi’s Sword?

Speaking of Sun Breathing, we must mention Yoriichi Tsugikuni. Yoriichi was one of the strongest swordsmen in history, and he wielded a black Nichirin sword, just like Tanjiro. Yoriichi’s sword was not only incredibly sharp but also carried deep symbolic meaning, representing the pinnacle of swordsmanship. This suggests that Tanjiro’s black Nichirin blade may not be a mere coincidence but a sign of destiny, linking him to Yoriichi’s legacy.

Tanjiro’s Sword: A Fusion of Water and Sun Breathing

Although Tanjiro’s sword is black, he initially masters Water Breathing. While distinct from Sun Breathing, Water Breathing shares some similarities and could have been influenced by Sun Breathing techniques. As the story unfolds, Tanjiro gradually discovers the true potential of his black Nichirin sword, combining elements of both styles to forge his own path in swordsmanship.

Did Tanjiro Use Rengoku’s Tsuba (Handguard)?

Kyojuro Rengoku, the Flame Hashira, plays a crucial role in Tanjiro’s development, deeply influencing his understanding of swordsmanship and the power of breathing techniques. While Tanjiro’s sword remains black, his interactions with Rengoku show that he is not limited to Water Breathing alone. Although Tanjiro does not directly use Rengoku’s sword tsuba (handguard), he absorbs lessons from multiple Hashira, shaping his own unique fighting style.

Did Tanjiro Master Sun Breathing?

As the story progresses, Tanjiro gradually masters the techniques of Sun Breathing. During his battles—especially the final fight against Muzan Kibutsuji—Tanjiro showcases the immense power of Sun Breathing. While he initially does not understand the significance of his black Nichirin sword, his relentless determination leads him to uncover its true power. His black sword becomes a symbol of his growth and resilience, setting him apart from other Demon Slayers.

The Connection Between the Mist Hashira and Demon Slayer Legends

Tanjiro’s interactions with the Mist Hashira further highlight the connections between different swordsmanship styles. While the Mist Hashira follows a different Breathing Style, his relationship with Tanjiro suggests that Tanjiro is absorbing knowledge from various sources, ultimately creating a new form of swordsmanship. His black Nichirin sword symbolizes this fusion, proving his potential to surpass previous generations.

The True Meaning Behind Tanjiro’s Black Sword

Even though Tanjiro’s sword is black, it does not mean he is weaker than others. In fact, the black Nichirin sword represents his deep connection to Sun Breathing, a technique stronger than all other Breathing Styles. Through perseverance and hardship, Tanjiro eventually understands the true meaning of his black sword, unlocking its full potential in battle.
