Fated | KNY Y/N FemReader!

When a girl wakes up inside her favorite manga, Kimetsu no Yaiba, after throwing herself in front of a truck to save her best friend, she arrives with nothing but her memories, and the sinking realization that to save everyone, she must become stronger than she ever imagined.

Thrown into a world she once knew only through pages and screens, Y/N is forced to confront a terrifying question: If everything around her is fiction... why does it feel so real?

She thought she knew this story. But stories change when you step inside them.
She hides the truth of what she knows.
She hides the truth of what she is.
And she hides the whispering fear tightening around her heart: If this world is a story... does she truly belong in it?

But the demons grow stronger. Her strange instincts sharpen. And the line between fiction and reality begins to blur.
She feels their hands, their warmth, their grief, emotions too vivid to be "made up." She begins to wonder: Are they really fiction at all?

Caught between the weight of a previous life and the bonds she's forming now, Y/N must decide what she's willing to become, and what she's willing to sacrifice, to protect the ̶p̶e̶o̶p̶l̶e̶ c̴̄͑͛̃̿͆̇̃h̶͗͒̒̂̇ả̷̌͛͑͆́͌̃̾̕̕͝͝r̸̛̦͍̪͇̫͔̩̻̭͓̣̿̽̽͒͂̋̑͆̓̓̈̀̈̕̚a̷̛̼̓͗́͑̆͆͋͌̔̂c̸̰̫̺͔̩̦̱̠̑̚͝t̶̤̬̜̜̭̤̱͎̩̣͙̺͕͎͛̎͊̈́̋͊̾e̸͛̄̾̈r̶͆͗̑̀͗͌͂̔s̶̡̰͎̝̭̙͓̬̟̾̄̓̾̏̽̉̈́̓̉̑̆͊̏ who believe in her.

A story of second chances, hidden truths, and a girl determined to rewrite the fate laid before her.
Caught between the fate she remembers and the fate she refuses to follow, Y/N carves her own path, reshaping destinies, forging impossible bonds, and discovering that sometimes the line between reality and fiction isn't a line at all.

It's a blade.
