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.
