Maybe she's somewhere with Koishi?

Ah! Could be! ...Hrrm. That's kinda troubling in its own way, huh.

Miss! Miss!

Oh?

We looked all over the Underground, but we found no sign of Okuu-san! It seems like she must've gone outside...!

I see. Thanks for the info. But... Did I order you to do that?

Oh, no, umm... You're just always so good to us, so...!

Hmm. That's very nice of you.

I'm heading out for a bit!

Mm-hm.
