The Haibane Renmei (灰羽連盟 - Ashen Feathers Alliance, officially translated as Charcoal Feather Federation) is an organization in Guri dedicated to helping haibane in their daily lives and in achieving their Day of Flight. Their temple is situated in the western cliffs, not far from a waterfall. A graveyard is mentioned to be nearby.
Constitution, origin and operation
Known members include Washi (the Communicator), the gate keeper and members of the community watch. The Tooga also seem to be closely related. With the exception of the gate keeper, it appears that the members are all former haibane who failed to overcome their trials. They dress in dark coloured robes and wear wooden masks, fake wings with indicator bells, a head scarf, and an amulet. They mostly tend the Temple and its surroundings. Their unspoken leader is most probably Washi.
The temple's building itself is cylinder-shaped, surrounding a circular garden populated by lush greenery. An underground passageway opening from the temple leads to the inside of the Wall.
Renmei members regularly travel inside the wall by the boat and collect kouhaku (light leaves) that manifest on departed haibane's name tags. These are then used as the base material in the production of halos. Also see the relevant pages on the Wall and Halo Symbolism.
