Disaster.
When heard for the first time, one would usually think of a natural disaster like an earthquake or tsunami because that's indeed the case. But in the novel 'Song of Nightmares', that word had a different meaning.
In fact, there was a statement like this in the original novel.
「 Some can regress upon death, while others may be sent to a different dimension to start over. In truth, it all depends on the roles they're given. But there are those who are given the role of a calamity, and that will become their fate 」
Therefore, they are people who could not escape from their role as destoryers and become a possibility in the story.
