Aw man, I just noticed that I didn't list the classes.
1. Rookies- or known as rooks to the other classes. They are restricted from going on missions given to Uchiha Elite (UE)members. They are able to go on missions with their teammates, given to them by their sensei. They also have to study everything about the Uchiha clan, including how to use their sharigan, and they have to train rigorously.
2. Juniors- are able to go on UE missions, as long as they are supervised by their mentors. You're required to train even harder.
3. Seniors- the last class before graduating. They are allowed to go on missions along with other juniors, without the supervision of their mentor. To graduate, they have to be recommended by their mentor.
4. Graduates- (not a class) now that they are official UE members, they are able to go on S-Rank missions on their own. They are given the mark of the UE and are capable of traveling in groups of more than 5 members.
That was a lot for a comment.
