Senkuu intends to rebuild civilization through science, and his newly awakened friend Taiju Ooki has the strength to help. Millennia have passed since a mysterious green light turned humanity to stone. With nature having overtaken the modern world, the two friends must work from what remains.
For Taiju, the catastrophe interrupted a confession of love to Yuzuriha Ogawa after five years of keeping his feelings to himself. When he finally emerges from his stone state, he discovers that Senkuu has already been awake for months. Combining Taiju’s physical power with Senkuu’s scientific knowledge, they uncover a way to restore other petrified humans.
Reviving people, however, brings opposition as well as progress. Senkuu’s ideas face challenges from others who awaken, threatening his plans for civilization’s recovery even as the cause of the petrification remains unexplained.
