There is a constant stream of sound coming from Asuka, either screaming with her attacks, or yelling at their allies they're supposed to be protecting. A second wave is starting to surround her, but as soon as it looks like she's faltering, she knocks most of them back.

"Someone block up that door again, or we're going to be swimming in them!" She has some choice comments for her other allies, but then, as the next few enemies charge, something seems to be briefly going wrong. It's hard to see details between the group of crystal bodies around her, but Asuka is physically holding off the front of another wave with her blade, pushing back to prevent them from charging forwards any more.
