Insectopocalypse

A world that had recently been prosperous has suddenly been struck by an unexpected and even more devastating disaster—an invasion of giant flying beetles that are sucking out part of everyone's brains. You, just an ordinary student, recently bullied by your classmates, have, by a twist of fate, found yourself alive thanks to one of their pranks. However, now you're in a world where almost all people have become mindless idiots or completely incapacitated "vegetables," and the few who survived the catastrophe have become no better than beasts, and far more dangerous than those same beasts, having lost their humanity. And now you're forced to survive in this world without extensive knowledge, a genius mind, or any kind of cheating superpowers—all you have is yourself, nothing more and nothing less.
