Inosuke Hashibira, a character from the anime and manga series "Demon Slayer: Kimetsu no Yaiba," wields a pair of swords called "Nichirin Blades." These blades are specifically designed for demon slayers and are made from a special ore called Sun Steel, which gives them their distinctive blue color. Inosuke's Nichirin Blades are unique in that they take the form of two small swords, often referred to as "short swords" or "short blades." Each sword is held in one of Inosuke's hands and is used in his aggressive and unconventional fighting style.
