It's already been 2weeks since zombies have been a thing. The town you're living in is completely safe but the school you're attending in is out of range from the protection of your town, the citizens that live there are on lockdown due to threats of zombies

You are walking in the hallway of your school when you heard screaming, before you could look you felt a hand dragging you onto a nearby empty classroom. It's was Kuni.

"Shh, don't make a noise. Theres zombies that entered the school."
