In the world of Demon Slayer, the Hashira are the most powerful members of the Demon Slayer Corps. These skilled swordsman are the pillars of their organization. They protect all of the other Corps members, and are regarded as the strongest among their peers. Finally, these elite warriors are highest in rank besides the Corps leader. (I try my best to make them not act out of character, so if they act out of character then I am sorry).
