I Crossed the Mountain Pass and Found Myself in Another World — A Slave? What Kind of Hard Mode is That? —

I was shunned by those around me because of a cross-shaped scar on my forehead. One day, I was struck by severe pain on a mountain pass and died. When I awoke, I found myself in another world as a baby. I thought this meant I could start my life over from scratch—but that hope was short-lived. Even in this new life, the strange mark on my forehead caused my parents to find me repulsive, and I was sold into slavery. This is the story of a protagonist who starts as a slave in another world and gradually grows stronger.
