Mirror of All Things

I naively thought that "survival" was the lightest price. Until I realized that every breath I took was devouring memories - those old selves, corrupted by the strange aura, were crawling out of the depths of the Mirror Abyss. It turns out that living itself is a price, but since I have chosen this price, then I will use my power to protect the people I love and the people who love me. I can't tell the difference. In my memory, I began to search for myself. I discovered many different versions of me, with different identities and different personalities, but they are all me. Which one is the real me?
