Taiju's brawn and Senkuu's brains combine to forge a formidable partnership, and they soon uncover a method to revive those petrified. Taiju learns that Senkuu has developed a grand scheme-to launch the complete revival of civilization with science. Among a stone world of statues, Taiju encounters one other living human: his science-loving friend Senkuu, who has been active for a few months. Several millennia later, Taiju awakens to find the modern world completely nonexistent, as nature has flourished in the years humanity stood still. Just when Taiju begins his confession however, a blinding green light strikes the Earth and petrifies mankind around the world-turning every single human into stone. After five years of harboring unspoken feelings, high-schooler Taiju Ooki is finally ready to confess his love to Yuzuriha Ogawa.
