7 Seeds is a Japanese manga series written and illustrated by Yumi Tamura. Set in a post-apocalyptic future, 7 Seeds takes place in an unspecified number of years after a meteorite hits Earth, where new species have evolved, and follows the struggles of five groups of young adults to survive after they are revived from cryonic preservation. The title comes from five groups of individuals in cryogenic chambers along with supplies, called "seeds", laid down by the Japanese government.
