[Is that a compliment or not... she doesn't sound particularly tsun-ish when she says it, so he chooses to take it as a good thing.]

Kashuu-kun is a good teacher. One of our best. [Granted, Namazuo wholeheartedly believes all his companions are amazing at what they do. But Kashuu is talented and versatile enough to be useful to most of the students who come through their doors. That kind of adaptability is rarer than some might think.] Perhaps we'll see him outside, and he'll be able to find something better for you.

[He's a poor substitute, he knows. A stranger will never be as comforting as a friend in a place like this. But he'll try his best for her anyway--because she's Kashuu's friend, and she's alone, and because that's just what he does.]

We can leave now, if you're ready.
