Chizuru would say that at least he doesn't have that pressure here - sure, the stakes are often high in Trench, but it's usually more about one or two lives than an entire world - but she knows that even while Nara'a is here, he has a hard time forgetting about everything back home.

So she pauses, thinking, and then-- "You do that though."

Maybe she can't reassure him about anything else, considering she can't change a thing about the world he comes from and everything going on here, nor about the nature of this place. But she can reassure him about the one thing she does know.

"You've helped me, you know. Multiple times. And.. your kindness always makes me happy too."
