Demon Slayer: Kimetsu no Yaiba

The swordsmiths possess extraordinary skill in forging, repairing and maintaining weapons known as Nichirin Swords in secluded workshops in the village. These blades are essential tools for the Demon Slayer Corps, as they are the only weapons capable of effectively killing Demons. Due to the critical nature of their work, the swordsmiths' workshops and dwellings are safeguarded with utmost secrecy, their locations veiled from prying eyes and demonic threats alike.
