Im not sure but it is most likley a simmilar thing to Rimuru's "battle mode". Just to be clear it is not a skill, when it is not activated there is like a limiter on their skills so their presence isn't so overwhealming so when they activate "battle mode" it disables the limiter and they can fight with their full strength.
