Her task was to stop communications, and Benimaru mentioned he can't contact Rimuru, so as far as that goes, I doubt she did something else than what was asked of her.
And safe to say, everyone's fucked? It's interesting that they went ahead with this plan, when the first phase was to incite a commotion for a righteous war, but if they were planning to attack regardless... Not sure why they sent the 3 otherworlders with that mission.
Unless Rimuru is inside the barrier all along disguised bwahahahaha.
Edit: Just noticed that Rimuru didn't show up in the whole episode, is this a first?
