Battle Academia - Clubs

Now...the lore gives us a fair bit about the BA skins - that they all go to academy together, that it's kind of reminiscent of the RWBY universe/MHA universe in that these sorts of academies train students to pretty much be akin to a military task force, and that to further supplement each individual's thirst for a specific area, they have clubs.

Other than the assassin club being one of the only clubs allowed to kill people through school sanctioned duels, we don't really have a lot of insight on the actual purposes and rules of these clubs, which I feel are pretty important, considering that we're seeing them get sorted by Riot to these things like Hogwarts.

If we're going to see more within the skin line (and we sure as hell are, I'm sure) then I'd like a bit more information on the general rules that this universe goes on, particularly these club activities, possibly within a comic series?
