Let's begin with the process of actually creating a club. Firstly, not just anyone can create a club, if not, there would be over a hundred of them in the Academy.
Secondly, the process is not time-consuming, and depending on whether or not it is approved, it usually doesn't take that much time for the student to find out.
To create a club, a student has to have achieved a certain level of merits, and this is why First years are ineligible to run one. The plus side, though, would be this merit doesn't necessarily have to be from the Academy.
Contributing to society in general, such as demon subjugations, community activists, environment members, and so on. It doesn't matter as long as you contribute to society and Humanity in general.
