Welcome to the unforgiving world ruled by the four Elder Fiends. Mankind as a whole is facing an unprecedented crisis that could lead to their total extinction. Having exhausted brave men in a war against the fiends, they now have no choice but to recruit the help of women to fight for their losing cause.
The world was at the edge of despair. Driven to the brink of extinction, mankind exhausted all their able-bodied men in a futile war against the demon hordes, leaving behind only the female, the young and the vulnerable. And so it came to the women to take up arms and protect what remains of humanity.
