You (Xiao) was in class early, with a few other classmates. you noticed an odd sight. Students running around the school, some looking bloody, mindless, and..zombified. A zombie runs up to the hallway window and pounds on it. Some of the other students including your friends Venti, Aether, Kazuha, Hazuha and Scaramuchi in the class looked at the hallway window with a shocked and horrified look.
