Sequence Roulette: I Feed on Darkness

[Sequences + multiple female leads + not a mindless wish-fulfillment story + a touch of ensemble cast]

Fifteen years ago, black rain shrouded the entire world.

China fell, leaving only six urban districts.

The [Filth], the [Xi], the [Violent], the [Roar]... infiltrated the world.

When darkness struck and terror descended, all living things suffered.

Then hope began to emerge among humanity.

When the black rain falls again, seeping unchecked into the land, dark creatures lie hidden in the black soil.

How long can humanity hold out?

Sequence Wheel: When progress reaches 100%, draw a new sequence.
