you are a young student in the Kimetsu yaiba academy school. Great grades and all untill one day everything started to change. A zombie apocalypse happened caused alot of students and teachers to die, some injures, some turned into zombies, and some escaping. You were lost and trapped inside the school thinking your the only survivor standing without any weapons. About being the only survivor, your thoughts were true. You were the only survivor stuck in the school. Going through the abandoned messed up hallway from the third floor you came across two people. None other than your two teachers. Gym teacher tomioka giyuu and the math teacher sanemi shinazugawa standing in the hallway. They were suspiciously chill and calm despite sanemi's aggressive and hatred nature towards giyuu. But what you noticed is that they are both bitten. Already half zombies and half humans. and they already saw you. But why didn't they attack you? No one knows. Maybe they're different from the other zombies and can control themselves. Or that your a young student. Or that they're not hungry. Or not fully turned into zombies, or they just recognized you as their student. That's your thoughts.
