The True Demon King

The meeting and butterfly mansion

I had woken up after the mountain madness I don't know what happened to nezuko but I woke up to somebody screaming at me and then I saw all these people and they were introduced as the hashiras, Fire Hashira Kyojuro Rengoku, Sound hashira Tengen Uzui, Insect hashira Shinobu Kocho, Mist hashira Muichiro Tokito, Serpent Hashira Obanai Iguro, Wind hashira Sanemi Shinazugawa, Stone hashira Gyomei Himejima and lastly the Love pillar Mitsuri Konroji they looked very confident but there was this one hashira that caught my eye... Muichiro Tokito the mist hashira his eyes were dull but it seemed like a calm ocean view I thought they were beautiful, but I could not think about that right now I start looking around and sit up asking where nezuko is then the wind hashira came from near a gate and he had Nezukos box and a sword he stabbed Nezuko and I was too angry to control my emotions and got up and attacked by head butting him I grabbed Nezukos box and said
"If you hurt nezuko you will answer to me I don't care if you a hashira I don't even care if your Muzan Kibusuji I will attack you for hurting my younger sister"
Everybody was shocked and then the two twin girls announced that the owner of the household was there. Sanemi grabbed my head and slammed me to the ground to bow to him I did not mind bowing but that guy suddenly had class?! Well nevermind that I was worried about what he would do to nezuko but once I heard what Mister sakonji wrote and I felt so bad that he had to go to such lengths but sanemi still did not believe that she would not kill or eat anybody he grabs nezuko after Iguro pinned me to the ground sanemi cut himself and dripped his blood on nezuko he could hear her growling I got worried for nezuko and broke the ropes thanks to giyuu I was able to run to the edge I made sure not to go in the shadows because it's rude to enter somebody else's house without permission I screamed nezuko she turned her head from sanemis arm and people were shocked but glad their friend was ok and not eaten not like she could eat him anyway well that what they all thought but I know nezuko she probably can but she won't eat a human ever and I will make sure of it but nevermind that I noticed that the master of the house could not see due to a curse put on him by the fake demon king muzan

(My AU my rules, I know it's an illness that caused him to be blind but I want some DRAMA~)

After all of that, I ended up in the Butterfly mansion with Shinobu. A few days passed and it had turned night on day five of being there I went to the roof cause I could not focus or sleep and then Shinobu found me and asked if I was ok I said I was ok then asked if she was ok because I could smell anger from her she gave me a shocked face when she tried to hide the fact she was shocked I noticed and said how can you smell if somebody is angry tanjiro well I answered in a calm tone and said I have a strong sense of smell so I can smell everybody's emotions and I can tell if they're a demon even without having to look at them and if they look human I will still know they are a demon because demons have a different scent then humans. Shinobu says
"You're an interesting one Tanjiro but I can tell you're a kind-hearted boy"
I say thanks and leave but I could not sleep still but that was ok I can just replenish that easily. I plan to go see the master during the night time and take him to my domain and tell him the things he needs to know like how I'm a demon but not one of the traitor's demon and more but I have to wait two days because he has a meeting with the hashiras tomorrow and he never gets alone except on fridays.
