Prophet Cat

My name is Elio and I turned into a black cat. My eyes can see the past and the future. I predicted that I would be killed by a werewolf. As for who the werewolf was, I didn't know. I walked around the world for ten years in order to find the werewolf and kill him. Until one day, I saw a variable - a descendant. Maybe he is a werewolf? But I don't have the force, so I have to find someone to kill the werewolf on my behalf.
