Synopsis
Picture this: you are going about your ordinary daily life—maybe hanging out with friends, enjoying a home-cooked meal with your family, or spending time with your significant other. Then, the next time you open your eyes, you find yourself thrown into a bizarre, unfamiliar world, stranded with five strangers on a boat that is rapidly sinking in the middle of a storm. For Natsu Iwashimizu, this is her new reality. Humanity has been wiped out, and the only remnants of Japan's population are five groups of men and women selected to be sent into the future in a desperate bid to ensure the continuation of the human race. While every other chosen individual possesses a practical skill—such as martial arts, specialized knowledge, or architectural expertise—Natsu is merely a timid high school girl who cannot even raise her voice to shout. This new world is perilous beyond imagination, and although Natsu appears to lack any useful abilities, she must press on with the others as they journey toward the "Seven Fuji" in order to survive.
