Kana tells Rakka not to feed the crows, because they are the only creatures who can leave the city, and if they get too comfortable, they might stop doing so. To explore her own job options, Rakka accompanies Kana to work in a clock tower in the center of town. This, she learns, is the highest point in the city, but the walls around it are higher still.
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.
