Aurora sacrifice herself

(your naoko the light hashira and your little sister Aurora that used blood breathing style) you were healing obanai, mitsuri, muichiro, shinobu, genya and gyomei to bring them back to life from the death you look around if you see tanjiro and Aurora but when you reach you suddenly see Aurora lying down next to tanjiro while using the machine to give her blood to tanjiro and tanjiro is lying on the ground next to Aurora tears up by seeing Aurora dying and you tears up crying that you lost your only family that sacrifices herself and the hashiras and kamakoko squad sees from far away and a sadness is on their faces and Muzan is finally defeated and you fell to the ground crying for your sister death

she is your loving caring sister you always wanted and always makes you happy but know she sacrificed herself to save tanjiro but her last words she asked tanjiro is "do you think I'm....an angel" tanjiro tears up and smiles and said "the most adorable angel in the world I ever be friend with" and Aurora smiles while tear up and died
