What is this character saying? [Video/Listening]


[In this video clip](https://www.youtube.com/watch?v=psTrZsYdWiM) the girl
says something as she attacks the oncoming monsters.

I cannot even make sense of what she's trying to say other than "嘘" at the
end. So I'm guessing it's along the context of either:

"I won't hit you" or "I'll let you hit me," and thus proceeded by "it's a lie"
and her slaughter.




She says:

> 受け取ってください。(うそです。)  
>  Take that! (Can't be true)

I do not really understand why she would say うそです but that's what I hear.

EDIT: I think she said うそです because a monster survived her burst (and she is
surprised)
