The Anime Lad
Rakka dreams of falling, then awakens inside a cocoon at Old Home. The young women who welcome her have small wings and halos. Soon she does too. They explain that she must work in the nearby town and cannot cross its wall. Origins remain unavailable.
Super Eyepatch Fox
A girl named Rakka emerges from a cocoon after a falling dream. Winged residents of Old Home give her a halo and explain the rules of their enclosed town. She must work nearby, while the impenetrable wall keeps the wider world and larger answers out of reach.
Gigguku
Rakka wakes inside a cocoon, grows wings, and gets fitted with a halo while everyone around her treats the impossible like daily procedure! Then she learns that the entire town sits behind a wall almost nobody can cross. One quiet beginning opens an enormous question.
Father's Basement
Viewers demanding a prompt lore document will find the opening almost perversely quiet. Haibane Renmei makes the uncertainty concrete. Rakka receives a halo, a work requirement, and a rule against crossing the surrounding wall, so the mystery grows from visible boundaries rather than constant ominous speeches.
