[Anomaly Code: Global Instance System.]
[Nature: Event/Scenario.]
[From a certain point onward, multiple "Disaster Instances" and "Apocalypse Instances" will appear around the world. Earth's living creatures can enter these instances, complete missions, earn rewards, and gain extraordinary powers.]
[Earth's living creatures who complete instance missions are called players.]
[Special rules for the global instances: If an instance appears and players have not cleared it perfectly within twelve weeks, the disaster phenomena inside it will manifest in the real world, by reasonable or unreasonable means, bringing total destruction to the world.]
[Instance entrances open once a week. Whether or not the previous week's instance has been perfectly resolved, a new instance will appear.]
[Anomaly Code: Global Instance System. There is currently no way to deal with it.]
[This anomaly cannot be resolved. It can only be endured.]
[This is a destined destruction, a struggle with no hope in sight.]
Natural disasters, human calamities, ghosts and monsters, anomalous objects.
The twelve-week deadline.
And terrifying instances of an unsolvable level!
As all kinds of disasters intrude on reality.
As everything heads toward its end.
Simply put, this is an apocalypse story dressed up as an infinite-instance novel.
