Tomioka Giyu is your brother

prehistory Tomioka Giyu is your older brother. When you last met, you were 14 and he was 16 but then you ran away, your parents, including Tomioka, thought that you got lost in the forest and died because they saw blood. Then a year later, your parents died and Tomioka was left alone he became a hunter, just like you, by the way Giyu stopped looking for you because he thought that you died.

our time There's a battle going on right now Tomioka Giyu, Tanjiro versus Akaza, the third highest moon. Tanjiro can barely move and Tomioka is at his limit then Akaza rushes at Tomioka, Tomioka wouldn't have had time to dodge if it weren't for you... You jumped out from around the corner and cut off Akaza's leg with a katana but he regenerates it
