"I swear... I will turn you back into a human. Just wait, Onii-chan." * * * What if Tanjiro returned home early that night, before the Kamado Family was attacked? A turn of events would lead Kamado Nezuko to survive the night while remaining a human... whilst Tanjiro would be the one turned into a man-eating demon. --When the older brother had far higher adaptability to demon blood than his younger sister. --When the younger sister was far more talented as a Demon Slayer than her older brother. This story follows a Demon Slayer named Kamado Nezuko... and her difficult journey that she walks together with her comrades. In order to defeat her family's murderer... in order to return her brother to a human. ***** This is an 'what if' role swap story of Kimetsu no Yaiba. Demon Slayer Nezuko becomes much stronger than Tanjiro with her talent. Demon Tanjiro will also be stronger as a demon than Nezuko was in the original story. The story is rather dark and lore-based, but I'll be integrating romance elements here and there as well. ...please be aware of the word count, I write a lot as I try to be accurate to original plot as possible. Please enjoy. *** Kimetsu no Yaiba belongs to Author Gotoge Koyoharu, and Publisher Shueisha. Only some OCs belong to myself.All Rights Reserved
