Active Pandemic

"Ants Brought Poison" That was what the outbreak of a certain plague came to be called. With an unavoidable transmission route and method—infection through contact with ants or the infected—humanity had no time to respond before 90% of the population was wiped out in the blink of an eye. People fought over food, killed each other, and deceived one another. The world had transformed into such a place. In the midst of this, Shironuma Michito realizes that he has developed antibodies to the plague. Through a series of circumstances, he ends up protecting three female students, and begins a life based out of a campsite. A somewhat comical survival story set in an apocalyptic world.
