Tanjiro’s Blade Turns Black

All demon slayers have been using the Nichirin blade for hundreds of years. This is one of the only blades that have the power to slice through a demon’s neck. In addition, each sword is made with hand, engraved with special abilities by the swordsmith. These blades are so versatile that they change in accordance with the fighter who carries them. This is where we get the theory of colors in the frame.

So, the Nichirin metal is found in the mines where the mountains are constantly under the sun. Any other poison or element other than sunlight is incapable of killing a demon. Thus, after the Final Selection, Tanjiro meets with the official Swordsmith of the demon slayer corps. Hotaru Haganezuka is the one who had been making swords for slayers for many decades.

Although there is no perfect explanation as to why the color of his blade is black, there are several reasons given by seniors in the story. Rengoku had connected the color of his blade with the breathing style that Tanjiro used. Initially relying on the Water Breathing technique, Tanjiro often used the Hinokami Kagura to fight the demons. This technique was later revealed to the Sun Breathing Technique that his father used.

The theory that made the most sense for the fans was about the life span of a demon slayer. It was said that every Demon Slayer who ever held a black blade lived a shorter life. This was an initial hint to Tanjiro’s early death in the story. Another theorist confirmed that all anime characters who are orphaned use a black blade. The list is long and includes the likes of Asta from Black Clover and Guts from Berserk.
