Tanjiro au

when you came back from old man Saburos house ,you find your family dead,you see that nezuko is still warm and you pick her up over your shoulder and runs through the forest,but you slip and fall you drop nezuko on accident,when you sit up from falling in the snow you see nezuko standing in the distance covered in blood,when u walk up to her she pounces at you you retrain her with a axe as her bare teeth sink into it,you see a man (giyuu)pounce at her with a sword,you quickly grab nezuko
