It was after Daki unleashed an attack on multiple people and Tanjiro was very angry about this so his eyes turned bloodshot red.
It was after Daki unleashed an attack and harmed multiple people, Tanjiro was extremely angry at this that his eyes were turning blood-shot red.
As he gives all of his blood to Tanjiro, Muzan says that if the boy survived this he would become the strongest Demon ever. Since he was the brother of Nezuko Kamado who was the first Demon to develop an immunity to sunlight and also the only one capable of using the Breath Style of Yoriichi Tsugikuni.
However, when Tanjiro was young, he didn't have any scar on his forehead. But, this changed when he saved his younger sibling from a falling kettle filled with boiling water. This burnt Tanjiro's forehead and left a small scar.
Tanjiro is considered to be Muzan's main nemesis throughout the series. After murdering the Kamado family, he was personally sought out by Tanjiro in Asakusa, Tokyo when the Demon Slayer recognized his scent from the scene of the murder.
Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that compliments his position as Upper Rank One.
Nezuko is the daughter Of Tanjuro Kamado and Tanjiro's younger sister who is turned into a demon.
Moreover, any Nichirin sword can become bright red regardless of the blade's original color. However, the blade can only stay bright red for a certain amount of time before returning to normal.
6/17 Hinokami Kagura: Dance
During the fight against Rui, in the face of absolute despair, Tanjiro pushes past his limits and unlocks a new form of breathing called the Hinokami Kagura. This style is facilitated by a special type of breathing and dance passed down to him by his father.
@IsekaiCitizen Yoriichi and the kamado family are not related but the most common and logical reason for Muzan killing Tanjiro's family is revenge.
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.
The first demon that is said to have existed was Muzan Kibutsuji. The one who turned him into a demon was a generous doctor from the Heian Period, who wanted to save Muzan from death since, at the time, he was diagnosed with a disease which would kill him before he turned twenty.
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.
Because he uses sun breathing, he would be immune to the sun, just like nezuko. Who is the most powerful person in the Demon Slayer universe? Referred to by Inosuke and Tanjiro as the strongest Hashira and Demonslayer.
In the case of Tanjiro, the mark used to be just a graze, but during his fight with the Hand Demon during the Final Selection, the mark changed. That life threatening condition altered him and afterwards, it develops into a flame-like pattern and is his new Demon Slayer Mark.
Black. Toho Co., Ltd. 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.
Gyomei's Gray Flail and Axe
Undoubtedly the strongest of all of the Hashira in terms of pure strength and power, Gyomei uses weapons that are also very unique. While they are still considered Nichirin blades for all intents and purposes, Gyomei's weapons are a flail and an axe.
The only thing he's weak to is the sun. That is why he turned other humans into demons and spread his blood so that one of them might find a solution against the sunlight, so he can become truly perfect.
Demon Curse: Muzan places a curse on all demons that have assimilated his blood. If any demon divulges his last name "Kibutsuji" out loud, the curse activates, which causes their bodies to stop regenerating and allowing Muzan's cells inside the demon to take over and kill them, regardless of their original intent.
As the main threat occupying the position of Upper Moon Six, Gyutaro's Blood Demon Art is tremendously powerful and extremely dangerous. With it, he can perform various attacks using blood from different parts of his body, and project them from his sickles as well.
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.
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.
Zenitsu Agatsuma
She apparently views Zenitsu as a "weird dandelion" and did not initially seem to reciprocate his feelings. Although the two are rarely seen interacting together, Zenitsu treats her with affection and care.
