Final Fantasy VOID

Short story "I can peek into all the secrets of others..." I said this to "I", although I am not sure whether the other "I" who gave me this ability and attached to this body has malicious intentions. "I will return double the sorrow that the world has given me. Do I need to explain such a simple truth a second time? " (Note: This work is original and does not belong to any other work.
