The tribe folk (族民 Zoku-min) refers to the sky people living in the slums who are thought to be descendants of criminals.
Overview[]
Origin[]
The origin of the terminology is not known as the slum folks are not heard referring to themselves as a tribe. The city people and the slum folks apparently live together on the same floating landmass and it is not confirmed whether they are a group of people who migrated at some point of time before the story.[1]
Prejudice[]
The people who live in the city condescendingly call the poor people from the slums as tribe folk or "filths" (汚れた者 Kegareta-sha). They regard the tribe folk as disgusting and does not want them crossing over the city. Most of the people caught red-handed and dropped into the Abyss are individuals originating from the slums, as a result people in the city only see those living in the place as descendants of criminals and see them as outsiders. Whenever a crime happens the people tend to believe it must be another tribe folk.[1]
