The year is 1912, the Taisho Era has just set in. Japan has rapidly progressed from a rural society to a modern Western-style civilization built on rapid industrialization and rapid modernization.
However, in rural Japan, it wasn't the same. Mythological creatures simply called "demons" roam the area, and is said to prey on humans for its sustenance and continued existence throughout centuries.
How could a world so beautiful, so elegant, and so prestigious could be filled with malevolent entities that seek to harvest the beauty out of it, how could it be that this world has the capability to make such evil exist.
It is not all dim however, somehow even through the darkness, light still finds a way to overcome it. The Demon Slayer Corps have been fighting these demons for nearly a thousand years, with their efforts going unnoticed, and within it, there lies the finest swordsmen and swordswomen in history.
But within it, lies a potentially hidden love story, completely overwhelmed by the darkness that is yet to be uncovered.
(WARNING: This story will be sfw, but there will be some blood, implied death, fighting, some gore mentioned, and a few other things that will be made aware by warnings. Pay attention to warnings at the top of any chapters please.)
Once in the mountain villages it was a custom that once a year on the night of the new year's first moon, an unlucky young lady would be selected and left for the demons to become one of the unlucky few who married such a husband. In exchange for this offering the demons would protect the villages and leave the humans in peace. Until one day a powerful warrior drove the demons away freeing the humans of them. Now 2,000 years later, it's become a tradition that once a year, a new young lady would be picked and wait for her future husband to retrieve her from a shrine in the mountains. And now the lucky tradition would fall upon Y/n L/n. It would be her own turn to take on the tradition and not have to worry about demons. After all that part of the old tradition was just fake, made up by paranoid ancestors. Everyone knew demons didn't exist.
...Right?
