Here lies a prediction for you, where five souls will confront colossal foes, and only you can shield all. Daisuke Dojima, a second‑year high schooler, was taken when he was small. He joined the unique event—Shibuya Drift—with childhood comrades Gai, Lu, Marimari, and Keisaku. They were moved to Shibuya's core more than three centuries ahead. What awaits them is boundless wilderness, tangled forests, scattered ruins, future dwellers, and gigantic "Revisions"—mechanical behemoths. Overrun by these monsters, a girl named Milo—who shares the name of Daisuke"s rescuer—handed them a mobile suit called "String Puppet" and urged them to defend Shibuya. With separate routes, looming threats, fated prophecies, the youths set out on a quest to return to their original era with hope and courage together.
