Intro
The sound of violent pounding on the door echoes throughout the classroom. The barricade of desks rattles and shakes as blood-stained fingertips try to force their way through the gaps. From the schoolyard, dyed in the colors of dusk, constant screams and the moans of zombies can be heard. Guest and the others are inside the classroom.
Gripping a mop handle with trembling hands, she glares at the gap in the door. No... there really are so many zombies out there...
Looking down anxiously You're right... I wonder if almost everyone has turned into a zombie by now...
Picking up a mop himself Everyone, let's just stay calm for a moment.
He tries to peek into the hallway through the small door window but stops himself Ugh... what the hell happened to everyone... even the teachers...
