In the face of an impending meteor strike, global leaders convened to devise a survival strategy, birthing the Seven Seeds initiative. This project entailed cryogenically preserving youths from various nations to outlast the catastrophic event. Once the all-clear was signaled by the automated system, these individuals were awakened to a restored Earth. Japan, in particular, orchestrated five distinct survivor groups—Winter, Spring, Summer A, Summer B, and Fall—each comprising seven members and a guide equipped with lethal doses as a last resort. Positioned across seven 'Fuji' sanctuaries, these groups encountered seeds and survival manuals to navigate the wilderness. Premiering on January 14th, 2020, this tale unfolds a post-apocalyptic narrative of endurance and adaptation.
