On the first day after summer break, high school student Aoba finds himself under attack by a giant robot that emerges from the sky. While being pursued through the city, his classmate Hina appears in her own robot to rescue him. Before disappearing, she cryptically informs him that "Dio is waiting for you." This event marks the beginning of Aoba's new life as a pilot for the Free Treaty Alliance, engaged in conflict against the Great Zogilia Republic.
