This is a prophecy. The five of you will eventually face a major crisis. The one who can protect you at that time is Dojima Daisuke, a high school sophomore who was kidnapped when you were a child. Together with his childhood friends Gai, Lu, Marimari, and Keisaku, they are involved in the mysterious phenomenon of Shibuya Drift. The center of Shibuya jumps to the future more than 300 years later. Waiting there are vast wilderness and forests, scattered ruins, and future revisions and huge mechanical monsters controlled by them. Shibuya, which is ravaged by monsters for unknown reasons, appears as if to save it. The girl Milo, who has the same name and looks exactly like Daisuke's benefactor in the kidnapping incident, appears. She provides Daisuke and others with humanoid weapons that only they can control, marionettes, and asks them to protect Shibuya. Daisuke, who lives on with the prophecy of Milo, the benefactor of the kidnapping incident, protects the fate of his companions. He is happy about the crisis that will eventually come and the power he has gained. However, the bond between the five childhood friends has been torn apart by the impact of the kidnapping incident. An isolated city. An unknown enemy. An uncertain past and a prophecy of fate. Boys and girls, fighting against the future to regain the present. We must return to the original era.
