STORY :

One day, a man claiming to be a god suddenly hacks a certain school's intercoms, ordering all of its students to team up and prepare to be transported to another world. There, they will be given special skills in the hopes that they become that world's heroes and defeat the Demon King that ravages the land.
The initial transfer is a success. However, Seiichi Hiiragi, who suffers from his classmates' constant bullying due to his somewhat undesirable appearance, is left behind as no one is willing to be his teammate. Nevertheless, the self-proclaimed god decides to send Seiichi to the parallel world and lets him join his peers. Unfortunately, this fateful ordeal causes Seiichi to arrive at a location deep in the forest, far not only from his schoolmates but from human civilization as well.
Desperately searching for a way to change his predicament, Seiichi's miserable days only seem to continue to worsen. Yet when all hope seems lost, Seiichi discovers a strange fruit known as the "Fruit of Evolution"—which may be his first step toward a significantly better future.
