At Hope's Peak Academy, a school full of extraordinarily talented individuals, Nagito Komaeda is an ordinary boy with no special traits or interesting skills to speak of-except for his incredible unluckiness. Just walking to school in the morning leads to a number of unfortunate accidents, which only escalate as the day goes on. Despite this, Komaeda leads a relatively normal life and is satisfied with his modest slice of happiness. But everything changes when a mysterious boy who declares himself the "Destroyer of the World" arrives to shatter this hopeless paradise.
