Volume 1 (which contained the first four episodes) left the viewer asking lots of questions about the strange situation that the people of Glie find themselves happily living in. With walls around the town and angel like beings having to work for free and wearing hand-me-downs, you wonder why they simply accept such bizarre circumstances - and in Volume 2 (which contains episodes 5-7) someone finally starts to ask questions....
...Rakka, the newest member of the Haibane community finds herself unexpectedly distraught when a practice of Haibane life takes her by surprise when one of the group leaves the community in a mysterious way. Coupled with the discolouration of her feathers and revelations about a "sin-bound" friend - she's not as happy as she was when she first settled in. I suppose in a way she is experiencing many of the insecurities and doubts that many teenagers face.
As with the first volume, these episodes build further on our understanding of the characters and of the Haibane lifestyle. It's not as striking as the preceding four instalments but it still maintains your interest and deepens the desire to learn more about this strange community and the rules which govern it. A darker side of Glie based life is starting to merge.
In a nutshell: This is building up to something big - or so it feels. The creators of this series have so far given very little away whilst constantly adding depth to a small ensemble of interesting characters. Although we are constantly learning about them, and constantly being spoon fed a back story to give us the bigger picture - there is still so much unknown. I'm looking forward to watching the rest of this series.
