The city sealing the Demon King's left hand is the Volcano City "Buto."
The city sealing the Demon King's right hand is the city reputed to be closest to "Heaven," the "Divine Grace City Nalune."
This city stands on what is known as the "Starfall Plateau," and it is said that when the gods endowed humanity with a sword and armor, they descended upon this plateau. Scholars from the White Church thus determined it as the place closest to "Heaven."
The existence of the Starfall Plateau is precisely why the Human Central Empire is worthy of being called "Central."
The sword and armor descended with the starlight, initiating the epic of resistance against the Demon Race.
The glory of the gods once again shone upon the world.
The one who received this divine gift was A·Gedora. At that time, he was a young man still unaware of his destiny, merely finding the sword and armor before him, he donned the armor and grasped the sword.
