The Seven Pupils of the Mist was created to improve the techniques and skills of children who had come from the Bloody Mist's graduation, and stands out from the other students which sought a position among the Seven Ninja Swordsmen of the Mist. After being accepted by the swordsmen, the child was selected to be one of the Seven's apprentice, usually being chosen by the holder who had a personality similar to that of the child or whose sword could be more easily handled by the child in the future. After that the child receive its own sword, which like the Seven Swordsmen, possesses unique skills, but are less powerful than those of the Seven.
