Buo's favorite character. Reki is the unofficial leader of Old Home. She's tough when she needs to be but is also caring and compassionate. Her role at Old Home is to care for the young Haibane as well as take care of New Feathers like Rakka. Reki is a major part of Rakka's life in Glie as she was the one who discovered her cocoon and stayed by her side during the painful process of growing wings. Reki is most always cheerful, at least on the surface. We receive hints of a darker past throughout the series. Despite whatever these problems from her past may be, Reki is a strong and reliable person, which explains why the other Haibane respect her as they do.

Haibane Renmei
A dream of falling from the sky...and then birth. Rakka is born from a large cocoon into the Old Home, greeted by a group of females with small wings on their backs and shining halos above their heads. Soon Rakka's own wings grow, a halo is placed on her head and she is told that she must work in the nearby town of Grie. She soon realizes that the town and the entire world they live in are confined behind the Wall, a tall, impenetrable wall that none except the mysterious Toga are allowed to exit.
