No Demonic Eyes: Restarting Life in Another World

I once thought that reincarnation was a gift from the gods. Until my power turned the only surviving companion into a surrendering puppet. "Please give the order, Master." In the girl's hollow blue eyes, the arrogance that once belonged to the nobles was gone. I stole other people's lives, and God gave me the eyes to see the truth, and the inability to touch the core of magic. I stole the warmth of others, and fate responded to me with a bloody dusk that turned everything into ashes. Eventually, I stole her. On the verge of death, my power twisted the soul of that proud girl, turning her into a sword that belonged only to me. When the surviving noble girl knelt on the ground and called me master with a cold and pious voice, I knew that my path to salvation had become a path of complete sin. Then, take her with you to ask for the final answer to this cruel world, to find out the truth about these eyes, and... Why I am here.
