Bokura wa Minna *ndeiru

There's a mysterious virus spreading across the world that makes you undead instead of dead—a phenomenon known as "zombification." Whether it's a corporate drone worked to death by his soul-crushing job, a victim of a violent assault, and a secretly poisoned target, these newly formed zombies now have to continue post-mortem life amongst the living. A darkly comedic anthology about ordinary people turned into zombies!
