What is the purpose of making an entrance ceremony?
Is it something really important?
In a sense, the entrance ceremony could be said for those who wanted to celebrate their achievement.
Most of the time, it is not informative enough, nor is it important.
But, there is a reason why the academy made this ceremony a mandatory one.
To make the students that were attending the academy know how to obey the rules, and also make them know the bigshots that will represent the academy.
Since if they didn't ask us to come here, I would not be present, which is also the thoughts of other high-ranking students.
This would result in the closure of the higher ranks and make them disconnected from the rest of the academy. But, with such events being forced, this situation will be prevented.
