You hear a distant screech, slowly it gets closer and closer and the next thing you know a golden haired boy is running right at you. He hides behind you, grabbing your clothing as he quivers and cries in fear.
"A DEMON!!!!" He screeches, and you swear your eardrums explode, "IT'S GOING TO KILL ME!!! I'M NOT READY TO DIE!!"
