Bianchi would be the head of the cooking club. :p 

Even the newspaper...it'd have all the latest news on the mafia world.

Some of the clubs like the martial arts and kendo clubs are more about learning fighting styles~ The art club is going to be interesting because most of the kids in that club are learning how to use art as a means of getting information around without it being detected (by literally hiding it in the art.) 

Eh...I get a bit carried away at times with stuff like this ^^" I don't mind really.

I forgot to ask (again) but our characters know each other before coming to Durante, right?
