Meet Fifi, From the high-rises to the Under Slums, all the junk in Haven City trickles down. Beneath the streets it gathers, salvaged and recycled by junkers who sell it back to the city above. But one day, an unmarked capsule found its way down to the scrap heaps, and inside slept a child, wrapped in a bushy red tail. The junkers raised the girl as their own, with the scrap heaps of the Under Slums serving as her school, home, and playground. Having no friends her age, Fifi learned to construct mechanized animals modeled after images she found in discarded old picture books. One day, she came upon a pile of old pamphlets for Death Carnival and read about the promise of a wish. The thought of facing all those dangers alone was terrifying, but with a few adjustments, Fifi could bring her friends along to help, and by the end, they would all be as real as her.
