There are two ways for a Demon Slayers to become a Tsuguko, one can either by apply for the position and get accepted, or they can be scouted by one of the current Hashira. A Tsuguko normally uses the same Breathing Style as the Hashira they serve under, though this isn't a strict requirement.
The purpose of the Tsuguko is to take the place of the Hashira they serve if and when said Hashira is put in a position where they can no longer fulfill their role as one of the champions of the Demon Slayer Corps, such as when the Hashira retires or dies.
