In the world of demon slayer, the main character, a young boy named Tanjiro Kamado was always the beacon of hope for those around him. His warm smile and presence that always gravitates a sense of love and compassion seemingly allowing him to change the lives of everyone for the better. Furthermore, his righteous goal of reverting his little sister back to human as well as defeating the dreaded demon king Muzan and ridding the world of the curse that is the progenitor of all demons and avenging his fallen family. However what if the story didn't revolve like this? What if Tanjiro was unable to traverse the mountain on that fateful day due to a sickness or broken leg and his little sister Nezuko was the one to do so instead? What if Tanjiro was taken by the demons and turned into one? Would he remain good? Or would he join the side of the demons and fight against humanity? Let's find out. I do not own Demon Slayer or any of the characters.
