Tanjiro is a young man of average height with fairly tanned skin and an athletic, muscular physique. He has ruffled black hair with red tips (and being entirely only burgundy in the anime), combed back to expose his forehead, and wide, dark red eyes with white pupils that appear lighter around the lower section of his irises. He also has a scar on the top left of his forehead, first seen when his mother brought him to watch his father perform the Hinokami Kagura dance. The scar originally looked somewhat like a graze that he got when he saved one of his siblings from a falling pot of boiling water, and it stayed like that And her hair was long and the rest of it was in a ponytail.

Also, the Kamado lineage had sun breath, which posed an extreme threat to demons; this was the breath type that even Muzan feared and wanted to destroy for thousands of years. It was a cold winter day Their father was dead, Tanjiro's siblings and mother were living in a mountain house and a wooden house. Tanjiro had siblings Hanako and Shigeru,Take and nezuko,Rokuta his siblings They were a poor family, so they carried coal in a basket and sold it to earn money to support the Tanjiro family And they eat blue spider Lily soup because they're poor Tanjiro was generally kind and polite to his siblings and cared about them. Being able to smell extremely well is one thing, but in Tanjiro's case, his sense of smell is so acute it's practically superhuman. Tanjiro's nose is so powerful that the villagers sometimes use it as a lie detector to figure things out.

Then Tanjiro goes to the mountain house at night and A villager invited him to his house and said that demons are outside at night and that it is dangerous outside at night and took him to his house and Tanjiro accepted and He came in And When he came to the mountain house in the morning, he dropped the coal he was carrying Because there was blood and also the metallic liquid filled the smell Because his sense of smell was very high and when he looked at the house he saw the dead body of his siblings nezuko holding Rokuta And when he looked at Nezuko, he saw that the door of his house door broken There were traces of blood his mom,Hanako,Takeo,Shigeru,Rokuta is died and but only Nezuko was alive but Muzan the king of demons attacked last night And he saw potential in Nezuko so he injected her with his own blood and made her a demon Tanjiro carried Nezuko on his back because she was the only one who was warm, that meant she was alive, he was running and with his speed.
