Find Memories and Master the World

Ru is just a code name, my name is not Ru. I am as, who am I. I'm crazy. No, I'm not. I am a god, hahahahahahahaha. Have you ever thought that there are two worlds? One world is reality. The other is also reality. No, it's not. Where am I? Find memories and master the world. There are two worlds, but no one can travel to the other world. But I just traveled through time. Yes, I am mentally ill, a lunatic, hahahahahahaha. The twilight world is dangerous, and that being does not allow anyone to discover it.
