In a world where anomalies such as Curse Spirits, Curse Energy, and People who can wield said Curse Energy exist... another kind of anomaly suddenly spawned out of nowhere.
Now this certain anomaly, compared to the other ones, is especially different, one could say. It's probably due to the fact that this is a happening that literally no one expected. Probably not even fate itself.
So one might ask, how would this anomaly affect everyone's fate? When even fate itself is not an exemption.
Well, that's the thing... No one really knows.
