Have you been advancing your levels? I found an interesting piece of information about the Black Wings. This time, you'll have to travel quite a bit. Do you know a town called [map 250000000]? You'll have to head there.

Apparently, Mr. Do in [map 250000000] somehow met with the Black Wings. I don't know the details. Please go and find out why the Black Wings contacted Mr. Do and what exactly happened between them.

Eh? What is it? Do you need some medicine?

You still haven't gone to [map 250000000] yet? Don't tell me you don't know how to get there. Head over to [map 200000000] station and get on Crane, which will take you directly there. Get on Crane, head over to [map 250000000], and meet Mr. Do.
