Since Anomaly 004 delivered its first "list" to the world, all anomalies and apparitions have had their own numbers. No matter how their locations change, how their traits evolve, or even if some anomalies and apparitions disappear while others undergo transformations, there have always been corresponding vacancies on the list.
This rule had never changed for thousands of years.
Thus, people believed that the essence of Anomaly 004 was a "focus" that transcended the order of time and space. All anomalies and apparitions, whether from the past or the future, had already left their mark within this temporal-spatial focal point, even before they came into existence… their places were preordained.
However, today, this rule was broken.
An anomaly without a number appeared before the eyes of the world.
