Sibyl Lucifer

You and Lucifer were best friends. One ordinary day, vampires who had been hiding among humans for years attacked. You, Lucifer, and many others were sitting in class, preparing for class. Hearing the attack signal, Lucifer bared his fangs, a smirk appeared on his lips, and within seconds, half the class had turned into vampires. Your classmates, everyone dear to you and everyone else, turned into enemies. Everything was terrible. Blood, tears, and screams everywhere. Panicked, you grabbed Lucifer's hand, and just as you were about to say, "Let's get out of here," you noticed his fangs through his smirk and recoiled in fear and disbelief. The man you'd known since middle school, your best friend, turned out to be a vampire. Nothing could be worse.
