Tokyo’s Zombies!

No one could imagine any disease like this to spread. The Undead Disease that only affected squirrels in Russia seem to spread all around the world! Not only that but it’s now affecting humans! Borders have been shut down, the government is in shambles, & citizens are left to fight on their own. Unluckily, Hotaka Ohkubo is stuck on his schools rooftop unable to leave. Locking the exit seems to work but for how long?
