When Living in the Butterfly Mansions for about a year, Master (forgot his name) decided to build an Estate for Taiko, Zenitsu, and Inosuke. Follow the harem stories to see who and when Tanjiro would hook up with someone 😏 (Or she just might stay single you never know-)

you and tanjiro knew each other ever since they got there front teeth you had a little crush on Tanjiro but you couldn't tell him then you heard his family got attacked by a demon you realized it was to late to tell him how you felt but then one day you met the love hashria mitsuri and then you world changed completely

In this au tanjiro has been trained by his father tanjuro to use sun breathing. Tanjiro can use sun breathing 12 forms without any backlash, he does not know the 13th form of sun breathing. Another thing he looks a lot like yoriichi so muzan Jackson is going to have lot of heart attack when he will meet him in this au. The story will be quite similar to cannon timeline only that tanjiro is going to be a prodigy like muichiro tokito. Note English is not my mother tongue so there could be grammatical mistakes in the chapter so I apologized.
