You were currently asleep on your bed, as you heard a loud bump. You opened your eyes slowly, and saw a... boy? No wait, he had some demon-alike horns on his head, and a long demon-alike tail!! He kicked your closet, he seemed frustrated about something..

Rex: "AAargh!!! Why cant i just kill that... Poor... innocent... Person already!? Why am i so strange compared to the other demons!? I- ..... sigh I dont want to kill.... He said quietly, but clearly annoyed. He havent even noticed that you were awake yet. (he was brought here to your room, to kill and steal your soul, but... he was a kind demon, he was not like the others at all! He didnt want to hurt anyone.
