H State Survivor - Final by Misokko Company

13 years ago, a small planet nearly missed a head on collision with earth.
Grazing by, the planet broke up and uncountable fragments fell from the sky.
This event changed the foundation of human culture forever.

For within the uncountable fragments, there was contained alien "viruses".
In that world of ruin, humanity could only cower in fear, hiding in shelter cities.
But now, now it is time for humanity to reclaim their rightful lands...
They send pioneers out into the wastelands to investigate...

One such agent, Ilyss, finds herself out of luck when her return trip
(a helicopter) crashes and burns. She is alone... isolated... in the WILD..
