[So, Sunny has run off into the desert. Nagito is on "inform the Ferryman" duty. He might be one of the better options, actually, since he approaches calm and smiling.]

Good afternoon, Ferryman-san. It seems like Sunny-kun has run off into the desert. We're looking for him now, of course, and I'm sure everyone has enough hope to find him--but we thought it would be best to let you know and ask if you'd be able to find him if we can't.
