District 24 first appeared in Kapitel 71. Frau regained consciousness in District 24 after escaping from Ayanami, who had tried to kill him. It is a very poor district with squalid living conditions, and many of the people who live there rely on begging and petty theft to survive. Ryuu, Nene, Barm and Moz are the only named inhabitants of District 24. District 24 is not part of the Barsburg Empire.
Hakuren Oak has mentioned that after the Raggs War, the weakest people, or those who were of no use to the Barsburg Armed Forces, were forced to live in the slums. The population of District 24 probably consists mostly, if not entirely, of such people.
