What is the "Otherworld Disaster"?
Literally understood, it can be interpreted as... a disaster coming from the Otherworld.
These types of disasters are mostly contagious in nature, capable of self-replication and spreading like memes.
Some are life forms like viruses, some are unique power systems, and others are uncontrolled creations of civilization.
However, Blue Star, this peculiar place, will transform all external life and power systems.
So, can their harmfulness still be sustained?
The answer is... most will lose their effect as if the underlying code is incompatible, but some can still persist.
Only those still posing a threat are named "Otherworld Disasters".
Documented Otherworld Disasters in Blue Star's history are not uncommon; many came to this world alongside Spirit Beasts and Magical Beasts.
Although most lost the possibility of normal spreading, they could still potentially propagate through Spirit Masters who have contracted these Spirit Beasts.
