In this apocalypse, although the ordinary people of the Magic Republic have always been restricted in their movements and are not allowed to leave the major shelters, this does not mean that they are completely isolated from the outside world, cut off from the world.
In fact, Dorothy and Denisha have always sent elite teams of Magic Armored Knights and Armed Heroic Spirits as the Investigation Corps to investigate those areas that have become ruins and where Calamity Beasts roam. Dorothy has read the many reports brought back by the Investigation Corps, which have been brought at great cost and sacrifice over the years.
The Investigation Corps had made a simple classification of the Calamity Beasts they encountered, from low to high: Village, Town, City, Nation, World—five levels.
