Story:
Twin brothers Yamato and Yūto Shiroaya, along with their childhood friend Michiru Iguro, receive a bracelet from a fortune teller. The bracelet lets Yamato travel one way to the future, with only one chance to return to the present. When he tests it, he lands five minutes ahead in a chaotic future where mobile statues are destroying the city. Michiru dies protecting Yamato and urges him to uncover the statues’ origins and weaknesses to stop the catastrophe.

Yamato and Yūto join other survivors to study the statues, but conventional military forces can’t stop them. Then Jirō Fuyukawa appears, a man with mysterious powers who has time-traveled himself. He calls his ability “Odo Genius” and passes this power to Yamato, who prepares to confront the lead statue, Aizen Myōō, within the five-minute window to try to change the timeline.
