🍥Obanai's sister🍥💀

randomized idea after playing a talkie. shout out to Kimiko iris for getting that random idea into my head😐🤗 Sub for more i guess so your Obanai's lost big sister. (crazy💀l) anyways. choose who you wanna be story _______________________________________ so you and Obanai had the same past and you two ran away together to hide away. you promised to obanai you 2 from then on will live together and you will protect him. but as life you know doesn't go as you wish. one night you both were chased by demons and that demon snatched you away and ran off with you. leaving him alone on the woods and thats the time when he met rangoku. (lets say this is from my AU) so now its been 10 years or so and hedid became a hashira as the story plqnted and for you. you became a uppermoon after you were taken away and was turned into a demon. you made your way throw to upper moon rank also becuse of you both having the same past. you became an snake demon uppermoon. upper moom 6 after gyotaro qnd daki died. now this is the battle and also the met of you both back but this time difference. you both stand in a battle field and Obanai is with... you know... Tanjiro, Nezuko, Inosuke, Zenitsu. you both stand at the opposite side ready to fight.
