When it came to demons, one boy knew exactly how they could be when cornering humans. He was sure of his death at that moment... until a kind soul came along and saved him from the inevitable death. Once he was saved, the boy knew this kind of incident would happen and immediately chased after his saviour, begging and pleading to train him so that this incident could be stopped quicker since he believed the more saviours or demon slayers there were, the fewer demons could try anything like with him. (Y/N) doesn't hate demons, but he doesn't sympathise with them either, so when he trains to become a demon slayer, he mostly does it so he can save people. But... what will happen when he meets a few individuals who believe demons can be sympathised with? Kimetsu No Yaiba isn't owned by me, I don't own the characters in the anime or manga. I only own this story.
