Mori No Kodou Kabe No Syougeki ANIME: Haibane Renmei OST: Haibane Renmei (2002) [audio]
aibane Renmei (灰羽連盟, Haibane Renmei? lit. Ash Feather Federation, translated by the author as Charcoal Feather Federation) is a 13-episode anime series based on the work of Yoshitoshi ABe. It began as an original dōjinshi comic series, The Haibanes of Old Home (オールドホームの灰羽達, Ōrudo-hōmu no Haibane-tachi?), but this was quickly superseded by the anime and was never completed. The anime series was also broadcast by Animax in its respective networks around the world, including its English networks in Southeast Asia under the French title Ailes Grises (Grey Wings).
The series follows a young (presumably teenage) girl named Rakka, a newly arrived Haibane (灰羽, Haibane?) (an angelic-looking being), and other characters in the city of Glie (グリ, guri?), a walled city with one gate through which no one inside is allowed to leave.
