7 Seeds: a project to prevent humanity’s extinction. When the government learns of a giant meteorite on a collision course with Earth the likes of which will produce a global extinction event, they select five groups of young men and women to be cryogenically frozen and awoken after the disaster has passed to live on as humanity’s sole survivors in an unfamiliar world.

A young girl named Natsu awakens to find herself on a deserted island along with several others, including a man calling himself their guide. An untamed jungle stretches out before them filled with gigantic vegetation and deadly animals, and they soon find themselves fighting for survival in this post-apocalyptic world bare of any other human life.
