ok but what do they do? can you use them as a unit or just a support unit?
I'm guessing since you have an SSR then it's a Eidolon. They are summons that give you a boost in stats and deal damage to enemies. Some can heal as well..I think. When a friend helps you fight, their Eidolon is used. Whichever one they have in the main slot.
