The **Demon Slayer Corps** is a secretive, centuries-old organization dedicated to hunting and exterminating demons to protect humanity. Originating in Japan during the Taishō era, the Corps operates covertly, unrecognized by any government, and is led by the Ubuyashiki family. Its members, numbering in the hundreds, are highly trained human warriors known as Demon Slayers who possess enhanced physical abilities such as strength, speed, and endurance, which grow with their rank[1][2][5]. Central to their combat effectiveness are specialized martial arts called **Breathing Styles**, elemental swordsmanship techniques derived from the original **Sun Breathing** style. These techniques allow Demon Slayers to channel their life force into powerful attacks capable of killing demons, who can only be destroyed by sunlight exposure, decapitation with Nichirin Blades (swords forged from a demon-killing alloy), or poison extracted from wisteria flowers[1][3][5]. The highest-ranking members, called **Hashira** (or "Pillars"), are elite warriors who have demonstrated exceptional skill and valor, typically by slaying many demons or defeating powerful demon lords[5][6]. Historically, the Corps has operated in secrecy, with its existence often dismissed as myth by the general public. The organization has expanded globally, establishing branches across continents such as North America, Europe, Africa, and Australia to combat the worldwide demon threat, each adapting their fighting styles and weapons to local challenges[2]. The Corps' structure includes a rigorous training system where former Demon Slayers become trainers (known as *Sodate*) who prepare new recruits through intense physical and combat training. Notable figures like Tanjiro Kamado, the protagonist of the "Demon Slayer: Kimetsu no Yaiba" series, underwent such training under experienced mentors[4][7]. Innovations like special boxes to safely carry demon allies and continuous refinement of their techniques underscore the Corps' commitment to
