When Sasuke's reputation increased after a year and half, many individuals joined with him for either his cause or theirs. This lead to a brand new group called the chosen elites. Each member wears the same Otogakure symbol that Sasuke does to show thier affiliation with him.
There are many members with several diffrent purposes in this group. It is not yet known what purpose this group serves.
Sasuke's student team, X, are also a part of the chosen elites. Some members of the chosen elites are also members of Koukon.
