I am Mio. I'm alive. Mayu isn't. I often see it again. The crimson butterfly. I tried to catch it to keep my sister close to me forever but the butterfly kept disappearing.
Mayu. Oh Mayu. Why did you have to die? In this way, with my own hands? Even though Mother (Shizu) always tells me it's not my fault, that I was forced to do the Crimson Sacrifice Ritual, I know it's not true.
I did the ritual of my own free will and you're gone. You're gone forever, leaving me alone, sad and abandoned. Why? It's not fair!
I always dream of you, my sister, and I always think about the same idea. If our roles were reversed. If you strangled me during the Crimson Sacrifice Ritual. With your gift, your sixth sense, you could have stayed in contact with me by linking yourself with the spirit world. We would have been together forever!
But that's not what happened. I killed you. You're gone. If there's a way, a ritual to go back in time and reverse our roles, I'm going to find it. For you, Mayu.
