I live in a world of chaos.

A world divided between humans and cyborgs.

A world where girls are snatched off the streets to become Marked Ones, their bodies inked with names and images. And now, now I am one of them.

I've been sold to a man called the Master. A notorious Hunter who kills cyborgs. I'm in the claws of the most feared man, trapped in a mansion with six other girls just like me.

I will find the way to escape this nightmare. To run from this world full of torture and death. And the Master's son, Ero, is going to help me. He'll help me save myself as well as the other girls. I will break the cage I'm trapped in, save the girl I'm falling in love with and destroy the evil that inhabits these four walls.

One way or another, I will be free.

Even if it means becoming the worst monster of them all.
