The touching story of a crooked swordsmith who rehabilitates a sociopath is considered the main focus ~ I guarantee that he will not be sweet and will not cost you money (←_←Although there is no money in the first place) the author only talks nonsense, there are bugs that involve the family, country and the world, and the three views of the subject may be a bit ridiculous according to the plot. No one knows whether it will turn into scrap metal during the tempering process, or whether it will be forged into a peerless sword.
