Picture yourself living an ordinary life—spending time with friends, sharing meals with family, or being with your significant other. Then, without warning, you wake up in a strange world, stranded on a sinking ship amidst a raging storm, alongside five unfamiliar people. That is the harsh reality facing Natsu Iwashimizu. The human race has been wiped out, and the remnants of Japan's population are divided into five teams of men and women, carefully chosen to carry on humanity's future. Every member of these groups brings a useful ability—whether it is martial arts expertise, specialized knowledge, or architectural skill. In stark contrast, Natsu is merely a timid high school student who cannot even raise her voice. Despite her apparent lack of survival skills, she must band together with the other survivors as they face the extreme dangers of their new environment, aiming to reach the "Seven Fuji" and fight for their lives.
