Another world, not unlike ours-----
A place where monsters are abducting the women.
A nefarious "inma" seems to be behind it,
using the monsters to kidnap ladies and eat them.
The inma is instinctively drawn to humans.
The inma's semen is a transformative elixir that turns them into demons.
Demonized women breed inma offspring, and the species flourishes.
The government of this world, unable to suppress the monsters,
offer a huge bounty to anyone who can.
Their hope is to kill two birds with one stone:
banish the monsters and end proliferation of inma.
But lives cost.
Nobody is up to the dangerous task.
Nobody, that is...
... except her!
