An announcement over the school PA system, delivered by a voice claiming to be a god, tells Seiichi Hiiragi's entire class they're about to be summoned into a fantasy world run on levels, stats, and skills. At that same school, Seiichi has spent years being bullied for his looks. When the other students pair off into groups ahead of the transfer, Seiichi is left out and crosses over completely on his own, with no one from his old life beside him. This is the original light novel behind the Fruit of Evolution manga.
