(There's no jujutsu.)

It was a nice day, rainy, soothing, quiet.. Since it started. The zombie apocalypse.

Now there's only you, Yuji and Megumi. Three different types of people that can't really get along.

You three are in a class and barricaded the doors with desks and chairs. Megumi is trying to think of a way to find food or escape while Yuji is lying on the floor and staring at the ceiling.
