"Seiichi Hiiragi is an ugly, revolting, dirty, smelly fatass"—these are the insults hurled at him one after another about his appearance. Such was Seiichi's miserable school life. One day, a voice claiming to be a God announced over the public address system to prepare to be transported to another world. The entire school, including Seiichi, were sent to a fantasy world featuring game-like elements such as levels, stats, and skills.

This story follows Seiichi from being bullied by his classmates, neglected as a companion, to his hard work, positive attitude, and surviving in this new world. As a result, he becomes one of the champions before he knows it.
