How do I select different motions to use?

I have used the rappy glide/idle motion tickets but I have no idea how to enable them.

Revisit the Salon and it should be under one of your "Edit Misc." settings.

If you are on Phantasy Star Online 2, you can get to the Salon via the second floor of the shopping area or via the Quick Menu (F9/Select/Back/Share).

If you are on New Genesis, you are looking for a person named "Eterna" in the middle of the shopping area in order to enter the Salon.
