[Ryunosuke fixes Kaeya with his sharpest glare yet. His head is throbbing, he's still exhausted from their fight, but this is much too important for him to give his response anything other than the utmost gusto:]

I could just as easily argue that declaring defeat before you've even attempted to grasp the full scope of the truth is every bit as foolish, sir.

[It's a strain, especially after using it for so long earlier, but Ryunosuke's Insight activates again almost without his meaning. He's still desperate to understand the Kenoma, this one in particular, and overall he just wants to know-- Do they really believe this guff that the Regent is selling them? Have they given an iota of thought to the fact that the Regent has every reason to lie to them?]

As far as I've seen, the death of this world being an inevitability is only such as declared by one person. Is that not true? One person, who, when pressed, dodges all questions and weasels their way out of providing any kind of assurance other than their own word that our worlds have already been finished by their hand. Then they say that this world is set to be the next, and so we should all gladly let them tear everything down. And you're really willing to just... Accept that?! Without question!?
