Demon Slayer: Reborn as Kokushibo's Elder Sister—Everyone Here Is My Little Brother

Wake up as the legendary swordswoman who raised the strongest demons? Check. Babysit a tantrum-throwing Iwakatsu while his twin runs wild? Daily routine. Dodge Muzan's recruitment pitch by faking your own death? Survival 101. From slapping Douma for his eating habits to dragging Gyutaro into street fights over his sister, life as the big sister of the Demon Slayer universe means one thing: chaos management on an apocalyptic scale. When you're powerful enough to make Upper Moons think twice, everyone else really is just a little brother.
