This is ridiculous. There's no way she can win, she's essentially powerless and all he needs to do is shoot her once. What kind of asspull could they possibly make to give her the ability to even survive here, much less fight him or try to stop him from genociding the beastkin? Fuck, why haven't they just genocided the beastkin already? If they have access to this kind of power, there's nothing the beastkin can do about it. This isn't an underdog story, the protagonists have utterly lost and the hero was irrelevant and never needed to be summoned in the first place due to the sheer military might of the antagonists.
