Who doesn't like events? Here at Domino Academy the students decide what events will take place(once they put aside their different races of course.) The process starts with each class giving their ideas to their class rep. The reps decide which two are about even after conferring with the student treasure about their budget. After that they hold a vote of which one they should choose. When the time comes, the class reps tell the student council presidents the event their class has chosen and (if approved)the council presidents start it(depending if another topic needs to be made.)
If the whole school is doing an event it's up to the Student Council(presidents, class reps, and treasurers(both student and class) to come up with an event that the whole school will do. That is of course if the headmistress doesn't have anything to say about it. Even if it isn't approved by her though if the council presidents actually agree on something and want to do it, they'll go to any means necessary to get it.
