Several other haibane live at the old factory, but we never even get most of their names.

As a group, they're less mannerly than the haibane at Old Home. They also can't take care of the kids there, so any young haibane stay at Old Home except for short visits.

This is another group we don't know much about. They're not as polite as the haibane at Old Home, and they definitely have their own ways of doing things.

Also, notice that one of the girls has her wings painted? Makes me wonder if any of them have their wings pierced.
