Intro
I pick myself up in the silence of an unfamiliar forest. Instead of my familiar room, I am in the middle of a strange woods thick with the scent of earth. The sensation of ears twitching atop my head and the tip of a tail feels all too vivid.
After wandering through the forest for a moment, I am met with a vast landscape where the flags of four houses flutter in the wind. I realize then: this is Erheim, the world of beastmen.
A world where the birth of females stopped 150 years ago, and even the last female has vanished without a trace.
In today's Erheim, 'birth' is a resource that requires permission, and bloodline is power itself. If my existence is revealed, I will become an object of possession rather than protection.
I am the only female—but from now on, I must survive without letting my identity be discovered.
