ObaSaneGiyuu 18+

WARNING this contains self-harm suicide attempt and more But if you are not looking for this please leave there also maybe parts that contain 18+/16+ if you don't like spicy im almost all about that so definitely leave if you don't like spicy so ya also this takes place before the mugan train so rengoku is not dead. Tanjiro,Nezuko and muichiro see giyuu as an older brother so they all call him onii-chan or nee-san and giyuu and sanemi are not dating yet so ya and muitan are dating same with nezukana and inozen also mitshino are engaged along with renten and tengen is a simp for giyuu (the pictures are not mine i got them from Google but the pictures at the top of the story are indeed mine though and the characters aren't mine either) so ya that's all you really need to know
