"No. No, i don't want to remember! It hurts-it hurts too much-" Y/N L/N, the youngest and newest hashira, found someone she had thought was dead. After her family was slaughtered by demons, Y/N made it her life's mission to kill as many demons as possible. But, overwhelmed with grief, she blocked out both the painful and joyful memories and pushed them to the darkest crevices of her mind. After passing the final selection, and killing one of the twelve kizuki, she soon moved up the ranks of the Demon Slayer Corps, and became the Dream Hashira. But the cheerful demeanor and fake smiles didn't last as long anymore, since Y/N's personality changed, and so did her skill. Will reuniting with a long-lost friend change Y/n for the better or for the worst?
