You (Y/N Kamado) born in the Kamado family as the oldest sibling (19) stayed with your sibling since you had broken leg that was currently healing. Tanjiro (her younger brother) who takes the job for Y/N heads down to the mountain to sell coal. when he comes back up the moutain he see's that his family was slaughtered so he carries Nezuko to the village to help Nezuko but they encounter Tomioka. After they were both unconscious Y/N appears to attack him from behind but he dodge. Wait for what happens next. Might change the story because i forget.
