Demon Slayer-Kimetsu no Yaiba- The Movie: Mugen Train explain the main weakness of Tanjiro Kamado’s black sword! When Tanjiro Camado first began his journey with the Demon Killing Corps, he acquired a specially made blade. But when he grabbed it, it turned into a completely black sword that seemed to carry a strange stigma. It was hinted that Tanjiro’s black sword would be an obstacle to his fight against demons (since it is understood that those with black swords do not live long), but the new film dug into the main weakness of this unique blade color.
Picking up shortly after the events of the first season, Tanjiro boarded a mysterious train with his sister Nezuko and Zenitsu Agatzuma and Inosuke Hashibira. The main difference for this mission from those of the first season, however, is that they board the train to support Flame Hashira Kojuro Rengoku in his mission. Here Tanjiro learns some great clues about his breathing techniques and sword.
At the meeting with the Flaming Hashira for the first time, Tanjiro decides to use this opportunity to ask Rengoku if he knows about how Tanjiro’s father adapted the Hinokami Kagura dance into a flame breathing technique. Although Rengoku does not know, he reveals the main weakness (and negative perception) of Tanjiro’s Nichirin’s black blade.
Rengoku mentions that those with a black blade don’t really have a chance to become Hashira (the strongest fighters who have mastered their respective Respiratory Elements) because they usually can’t decide which element to master. This is also the case with Tanjiro, because while he learned the techniques of breathing water, from Episode 19 onwards, Tanjiro was drawn to flame breathing.
Rengoku notes that this is a weakness, but there is a loophole. Noting how each generation of Hashira usually has a swordsman who can use both water and flame breathing techniques, this opens the door for Tanjiro to eventually grow into this position. Rengoku even gives Tanjiro a critical key to this new elemental mastery in the film.
So, while Tanjiro has an inherent weakness of his black blade, this can become his greatest strength if Tanjiro can not only control the Water, but also the Flame element. There is a precedent, so this also means that a path must be followed if Tanjiro decides to pursue the Flame element more.
