It's a side story where Tanjiro is Kokushibou's son and therefore a half-demon.
⚠️Spoiler alert ahead for some characters⚠️
sorry for the bad grammer but it's a traduction of my original story.
My name is Tanjiro Tsugikuni, I am the only son of Kokushibou/Michikatsu Tsugikuni and Mareno. My father has been training me in swordsmanship since I was 8, this year I turned 13. He had taught me the breath of the moon and hopes that I will fulfill his dream of eliminating Kibutsuji Muzan, the original demon.
That night everything changed. A group of demons with ranks inscribed in their eyes surrounded our peaceful home. One had no rank but crimson eyes, that was their leader, that was Kibutsuji Muzan. Hostilities were beginning.
Muzan: Kokushibou, you disappoint me. Me who appreciated you for your talent, your strength and your loyalty. I am really disappointed.
Kokushibou: Why are you here? Muzan-sama, Douma, Akaza, Hantengu, Gyokko, Gyutaro and Daki.
Douma: To punish you, let's see. Isn't that obvious enough.
Kokushibou: I doubt myself, but... It's not just that. Am I right Muzan-sama?
Muzan: Well done! It's not just that. Give us your son or perish.
Kokushibou: I refuse to entrust it to you.
I went out to see what was going on.

Tanjiro: Dad, who are these people?
Kokushibou: They are demons but they want to take you and I refuse. I taught you everything, take your mother and flee as far as possible before the end of the night.
Tanjiro: Yes dad, I'm going!
I took my saber that my father had given me and I was going to look for mum but... a demon had madethe trick and killed her, it was a lower moon, it was the first lower moon. I took my legs around my neck and ran away as fast as I could, crying all the tears in my body. Demonic Moons and Muzan were chasing after me. My father was running after them to protect me. I saw a man with a hoari of 2 motive, he saw me chased by demons, he took me in his arms and ran as fast as possible to get me away and put me in safety. I cried telling him that my father was fighting against them. Day broke and we returned to the scene of the massacre. I saw my father's saber and took it, I also got his kimono. My mother's body was still in the house, the man who had protected me buried it and we pray that his soul rests in peace, we did the same for my father despite his body is no longer there .
The man with the half coat consoled me and collected me, his name was Tomioka Giyuu, he is a slayer and the pillar of water. He took me to the butterfly house to see if I had any internal injuries and luckily I had nothing.
I met Kochou Shinobu, the pillar of the insect, his Tsugoku Tsuyuri Kanao who was around my age, Kanzaki Aoi and the little girls. ((I don't remember their name but I know there is naho)) Tomioka-san tells me that it would be better to have a meeting of the pillars to talk about my case.
