The Declaration Ceremony of the Arzew Student Council is an important event in Crepuscule, because it signals the beggining of the next generation's nobles. During the finale of the declaration ceremony, the student council president shows off his/her ability. This is very important because the strength of the president's ability can decide the power the student council will hold.

The declaration ceremony takes place at the Assembly Hall of Arzew, at the start of the school year. The leading nobles of Crepuscule come to Arzew to attend the ceremony.
