MuiTan

AU: Tanjiro met Sabito and Giyuu at the same time, but Tanjiro was 4 years old and Nezuko was 3 years old, so the old man adopted them since Tanjiro and Nezuko's family died of a sickness and their siblings weren't born at all.

Also Kaguya's kids are all like 14 now so yeah.

Tanjiro was chilling with the Harisha, laughing and smiling along with Muichiro mostly. The Harisha was smiling and talking until Zenitsu yelled, "Tanjiro!!! Inosuke is trying to murder me!!!". Tanjiro groans and yelled, " Inosuke!! Sit down!!! NOW!!". Inosuke did and was silent as a mouse along with the others. Tanjiro breathes in slowly and said, "Sorry Suke... " Tanjiro sat by him and hugs him. Inosuke was in tears a bit. Tanjiro said, "Shh~ I am sorry for snapping... I am kind of tired and haven't slept in a few weeks...". Inosuke put his head on Tanjiro's chest. Tanjiro sighed softly and sang a song softly,

Oh, hush, my dear, it's been a difficult year
And terrors don't prey on
Innocent victims
Trust me, darling, trust me darling
It's been a loveless year
I'm a man of three fears
Integrity, faith and
Crocodile tears
Trust me, darling, trust me, darling

Inosuke slowly fell asleep at his voice, causing Tanjiro to smile.

So look me in the eyes
Tell me what you see
Perfect paradise
Tearing at the seams
I wish I could escape
I don't wanna fake it
Wish I could erase it
Make your heart believe

Inosuke fell asleep fully, Tanjiro smiled and holds Inosuke softly and said, " sorry... ". Muichiro said, " Damn... You can snap... ". " ah... I haven't been able to sleep for 4 weeks now, watching Nezuko at night, cause she is now at that level of growing... Like... Demonly growing so I have to watch her, and dealing with other demons at night to... ", Tanjiro said. Nezuko was in shade, whimpering in pain, holding her head. Tanjiro hands Inosuke to Zenitsu and went to Nezuko and rubbed her head softly and said, " Shh~... ". Nezuko was in tears and cried in pain. Tanjiro holds her like a child since she was in her small form. Nezuko cried even harder in pain. Tanjiro got up with Nezuko on his back and covered a black blanket over her and walked out to the sunlight. Nezuko was asleep calmly. Tanjiro said, " good girl Nezu... ". Tanjiro yawns and slowly fell asleep onto of Muichiro still holding Nezuko. Muichiro saw Shinobu approach and hissed like a cat would. Everyone just went silent and was confused. Muichiro said, "Mine... ". Uzui said, " okayyy". Muichiro holds them and fell asleep. Mitsuri said, "so cute!!".

Nezuko and them all woke up and Tanjiro was awake to see Muichiro confused and said, " what? ". Muichiro said, " Why was I uhhh holding you?". Tanjiro said, "I-... Cause we both fell asleep". Muichiro nodded and hugs Tanjiro. Tanjiro blushes and said, " I- your short". "Next time I won't be... ", Muichiro said.

Tanjiro had a mission with Nezuko, Zenitsu, and Inosuke for 3 months while Zenitsu and Inosuke went for a day. After a week, Tanjiro breathes slowly and uses his Sun Breathing to cut all of the 7 demons head off. Nezuko was battling 2 demons. Tanjiro huffed to breathes as Nezuko went into her box. They reached a rock place to see it was the rock Tanjiro cut and said, " Sabito... I hope you are proud of me... I defeated that hand demon who killed you and the others...". Sabito appeared and said, "I saw Tanjiro". "Sabito...", Tanjiro said, smiling. Tanjiro hugged Sabito in tears, " I miss you so much... ". " I do to TanTan", Sabito said. Tanjiro wiped his tears and said, "Giyuu misses you also... Since we found you had passed away, I was so scared of that demon and Giyuu was depressed also... I killed that demon for you with anger and frustration". Sabito smiled and hugged Tanjiro then left. Tanjiro looked behind him and sees the old man and said, " Hey dad... ". " Hey Tanjiro, talking to Sabito again? ", He said
