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.

{ON HIATUS AND EDITING CRISIS}Demon slayer was created by Koyoharu Gotōge and doesnt belong to me, the cover credit all goes to the artist. Who would've thought that the Mist Pillar would had fallen for a demon girl of all people. He couldn't explain it like most things. Keeping his feelings bottled up wasn't good and he knew it but he couldn't let them out. Then that demon girl came and suddenly he felt different. Different about himself and nearly everything. The mist pillar had amnesia and couldn't remember most people's names but he suddenly could remember the demons? It just made no sense to him. He couldn't have loved a demon...could he?
