Town and Wall / Toga / Haibane-Renmei - S1.E2

Rakka's new companions take her into the town of Glie. She learns that most of the people here are not Haibane, that Haibane can only own things humans have stopped using, and that they are required to work. The wall around the city and countryside keeps everyone in; only the Toga can come and go freely, and only the Communicator can speak to them.
