According to the
When Tanjiro first got his Nichirin Sword on Demon Slayer, and it changed color to match the personality of its user like all Nichirin weapons do, many fans were surprised that Tanjiro's katana turned black.
Why Did Tanjiro's Sword Turn Black? Along with an implied a lack of skill, it is also said that swordsmen with black blades struggle to master a breathing style. Tanjiro utilizes Water Breathing, but unlike Tomioka, his sword isn't blue to reflect the breathing style.
Black is the most mysterious color of all the blades, and is held by the main character, Tanjiro. It is a rare blade and represents the sun; it also holds a theory that the demon slayers who own this sword are not to live a long life.
Tanjiro Kamado wields a black Nichirin blade, but the symbolism of such a sword is unknown. Black blades are seen as a rarity, as demon slayers who wield them are doomed to die young. No wielder of a black sword has ever become a Hashira, either. However, this is all superstition.
1. Tanjiro's Black Sword. Of course, the one who takes the top spot in terms of the best swords in Demon Slayer is Tanjiro's black Nichirin blade.
Tanjiro isn't affected by the sun or the red blades which Yoriichi has. Since he has all of Muzan's powers, he would gain his extra hearts and brains as well as all of his techniques with the Slayer Mark, transparent world, and sun breathing, out-classing Yoriichi.
That life threatening condition altered him and afterwards, it develops into a flame-like pattern and is his new Demon Slayer Mark. It remains that way and continues when he uses his abilities. This is a cool piece of mythos that will evolve as the story continues.
As Tanjiro pushed past the threshold of pain during this fight, he almost managed to kill Daki. The fuming rage that Tanjiro felt from seeing Daki destroy human lives helped him push past his limits while also making him bleed through his eyes in anger, resulting in his eye colors changing to bloodshot red.
As the battle reached its climax, Tanjiro was able to knock the doll's head off and discovered that the mechanical body contained a mysterious sword. Fans of the manga will recognize this sword as the one carried by Yoriichi Tsugikuni himself.
Tanjiro certainly did a lot of good with his Water Breathing techniques, but his ability to use Sun Breathing both gives him an edge in battle and allows him to stand out among the incredibly powerful Hashira he fights alongside.
In an interesting turn of events, as mentioned above, Tanjiro later uses the flame handguard from Rengoku's sword on the legendary Yoriichi sword he finds during the Swordsmith Village arc.
During his second encounter with Muzan Kibutsuji, he injures his right eye in the Infinity Castle. As the battle progresses, Tanjiro suddenly collapses and his wound begins to form a large mass over his right eye due to the poison inflicted on him by Muzan.
In episode 6 of Demon Slayer season 2, Nezuko entered a berserk state to protect her brother Tanjiro, causing her body to develop into that of an adult. She loses her gag, grows a single horn and gains vine-like patterns across her body.
Chapter 204 of the series reveals the extent of Tanjiro's injuries, and although he was able to survive the battle after seemingly coming close to death, he's far from 100 percent as he's completely lost the use of his left arm and can no longer see out of his right eye.
The scar changed again during the Entertainment District arc when Tanjiro fought against Gyutaro and Daki. Towards the end of that fight, he developed the Demon Slayer Mark that increased his strength in order to cut Gyutaro's head with his Nichirin blade. This mark was bigger than the scar on his forehead.
Tanjiro Kamado is the only (known) living user of the Hinokami Kagura, but unlike the Water-Breathing he learned from former Hashira Sakonji Urokodaki, Tanjiro learned Sun-Breathing from his and Nezuko's late father, Tanjuro Kamado. So the question now is: who was Tanjuro Kamado?
In the show, Tanjiro's father Tanjuro is shown with the exact same head "scar" as his son - and it seems unlikely that the explanation for this is that they both had the exact same scarring incident with a boiling hot kettle. As such, it's clear this is an inherited trait, and not the result of an unfortunate accident.
However, the trait that sets her apart from all other demons is the fact that she has the ability to conquer the sun, prompting the Demon King to call her the "chosen demon". Abnormal Demon Physiology: As the "chosen demon", Nezuko has several unique demonic traits that set her apart from all other demons.
However, she wasn't immune to the sunlight initially, as she got burned badly at first. So, in conclusion, her coming from a Sun Breathing user's lineage and not relying on human substance are perhaps the reasons for her immunity.
He is a Kanoe-ranked Demon Slayer and a member of the Demon Slayer Corps. He became a Demon Slayer in order to find a way to turn Nezuko back into a human, and hunt down the demon who is responsible for the murder of his family and his sister's transformation into one.
During Tanjiro and the rest of the Hashiras' showdown with the Demon King Muzan, Tanjiro is mortally wounded and dies. At the same time, Muzan receives a particularly fatal lil' booboo himself. As Muzan is about to shuffle off the mortal coil, he uses the last of his powers to turn Tanjiro into a demon.
The major literary reason for Tanjiro having such a hard head is to be symbolic of his determination and fighting style. Time and time again, Tanjiro is shown to press forward and fight on even when all hope seems lost.
The Purple Nichirin sword was used by the Upper-Moon One, Kokushibo. This sword is symbolic of the Moon Breathing style and is definitely one of the strongest within the series. Being a demon, Kokushibo's sword also has eyes attached to it.
8 Tanjiro Is The Only Living User
On the other hand, Sun Breathing can, presently, only be performed by Tanjiro Kamado. Though its techniques can be taught to others provided they have the guidance of a Kamado, there are no other known users who are currently alive.
