Tanjirou Tokito is a boy who came from a poor family. Tanjirou was the youngest of his brother's, they were all triplets. On an unexpecting night a demon attack their house, the only survivor was Tanjirou although he shortly after got amnesia. Read as Tanjirou becomes an amazing swordsman with a unique breathing style. Also please don't get offended, I don't really know much about amnesia and I'll be writing stuff that probably don't happen with people who actually have it. So please don't get offended.
