All For Nothing - Demon Slayer x Hashira! Reader

Y/N L/N is a daughter born to a filthy-rich family. She was supposed to be spoiled rotten. However, due to circumstances out of her control, she was outcasted and mercilessly abused.

She was a miserable and pitiful child, always on her knees apologizing for things that weren't her fault.

At a young age, her one goal in life was to grow up and escape this hellhole. She'd planned to remain useless in order to escape.

However, all of her plans came crashing down when her beauty caught the attention of a rich man. She was then engaged to the older man, her marriage being postponed til she reaches adulthood.

Y/N refused this and even attempted to kill herself. Surprisingly, the man was kind and even convinced her father to grant her 'freedom' until their marriage. Her father used her younger brother's life as a threat to keep her from never returning.

She got away, eventually discovering about demons and training to slay them. It wasn't long before she became a Hashira.

...

All of the other Hashira's loved Y/N. Her kind nature and bubbly personality drew everyone in.

However, what hid behind her smile was a dark, twisted and miserable life.

Would they be able to save her before it's too late?

Or will she slip away, embracing a future she believes to be bright an warm, which might not be the case...
