Ah awesome! :D I guess you'd start in Ruins of Alph where the rest of us are. Event 3 is yours to take, it's the only one available at least :p JPs with others can be arranged after the events. And you can look through chapters 1 and 2 and see if there's any wild pokemon from there you'd like to have on your team as you jump in.
... Look at me, hastily assuming your SU will be great and easy to accept. ;p;p
