When the people around us turn into monsters that know nothing but biting,
when the world's order is utterly destroyed by an unknown virus,
is this a natural disaster, or a shocking conspiracy orchestrated from behind the scenes?
What fate awaits humanity?
Forests drenched in rain, deserts buried beneath flying sand,
plateaus battered by endless snow and wind, swamps shrouded in thick fog.
Humanity has finally secured a foothold. Their eyes turn toward cities that once symbolized the old civilization, but are now under lockdown.
Rescue, war, research: people grow ever more divided on the road to rebuilding the world. But one thing remains unchanged: the earliest and purest conviction.
Survive, together!
