Aiyoku no Eustia

Five hundred years ago, angered by humanity's sins and arrogance, God recalled his Angels from Earth and the surface was consumed by Chaos. The last person who still prayed to God, the first Saint Irene, asked for his forgiveness. God listened to her prayers and lifted the city and land around her to save humanity from extinction. As the last bastion of humanity, the city of Novus Aether floats in the sky above the inhospitable surface, powered by the daily prayers of the Saint. More than a decade ago, due to the interruption of the prayer, the "Gran Forte" occurred, causing part of the city to fall to the surface and splitting the lower city in two.
