Another anime by Abe, also responsible for Serial Experiments Lain
After a dream of falling, a girl wakes from a cocoon, amongst a community of children and young women with wings and halos; which she soon acquires.
The Haibane, the winged folk, are outsiders in a community that is a small town, in a walled hinterland. Effectively, no-one leaves; except that Haibane depart as mysteriously as they arrive.
A slowly told tale of redemption. But not of the person you first expect.
Not a life-changing anime, but one I'm glad to have seen.
