In the Demon Slayer Corps, Hashiras are the highest-ranking members who have mastered a distinct breathing style and through relentless training acquired incomparable combat skills. To join their ranks is no easy task as one has to either slay a member of the Twelve Kizuki or be selected as a Tsuguko, the nominated successor to one of the Hashira. Usually, a Demon Slayer requires five years of rigorous training to achieve the coveted title. Even the talented ones end up taking around two years to become a Hashira and then there is Gyomei Himejima, who pulled off the same feat just two months after joining the Demon Slayer Corps.
