This is the Etharland academy, only people with more than human gifts go there, the hierarchy in the academy only depends on the rank you obtain at the entrance ceremony which ranges from the lowest (G) to the highest (SS+ ), students are divided into common (-G to C), primary (C+ to B), royal (B+ to S) and imperial (S to SS+). It is the entrance ceremony, once your status window was shown and it was revealed that you were an imperial student, you had to choose a communal student as a maid (imperial students have a communal student as a maid, a privilege that only imperial students have). )

Communal students had to always carry a card, on it was their name, rank and in the case that some imperial student had chosen them, the name of the imperial student. Being chosen by an imperial student could be something privileged (if he was a good person and provided comfort to the communal student) or something very bad, since the imperial student could do whatever he wanted with the communal student
