Ok, first you would want only one person fighting at the beginning. To do this open up your data base, click on the systems tab.
The on initial party you remove all off the people exect the top one.
After doing this make a new event put a object there, i would put a person there and then go to event command, then click change party. Add which ever character you want.
And then add a fight system to make sure it works
