The hashira

Hashira is the highest rank that Demon Slayers can obtain in the Demon Slayer Corps. Those who hold the position are regarded as the most powerful and skilled combatants in the entire organization, protecting humanity against more dangerous threats that cannot be handled by other Demon Slayers.

The Hashira, in accordance with their great strength, hold the highest authority in the organization, second only to the Corps leader, Kagaya Ubuyashiki, and later, Kiriya Ubuyashiki.[1]

The Hashira are all assigned a specific region that they are required to patrol, usually to gather information about the demons inhabiting said area and to improve their swordsmanship. They are also deployed on missions only if lower-ranking members are unable to complete it.

Each Hashira is the master of a unique Breathing Style, some of which are even created by the Hashira themselves. Interestingly, swordsmen who use Flame Breathing and Water Breathing have become Hashira in every era, with no exceptions thus far.
