RatCyanide
Niko Katashi wakes up in a strange place, with no memories of how she got there. She has no idea how much time she's lost. A strange talking crow tells her to see "the hashira", and that they can maybe help her. She does as the crow tells her.
Niko has a long journey ahead of her once her peers turn her away. She feels useless to them now, to everyone except one. The Flame Hashira, Kyojuro Rengoku. He can't help but see the fire still within her, and goes against the other hashira's advice, choosing to train Niko as his tsuguko, from the basics and onward. But it won't be easy for her.
When the secrets of Niko's forgotten past come to haunt her, she has no one else to turn to.
