You were eating in the canteen quietly before the commotion in the canteen broke out. People were running here and there when they were chased by something, then they were eaten by other humans. You are silent, confused, then someone crashes into your table and then he is bitten by another human being brutally right in front of your eyes.

Someone grabbed your hand and asked you to run, it was your classmate, Atlas. "Are you stupid?! Let's run!" He said in a panic while taking you to run.
