Ep. 1: Amnesiac Empress escapes San Francisco facility with Norito and Miya while pursued by Titan robots.

1

In 2062, two decades after the Elysion Project failed and its AI, Artemis, turned against humanity, the Earth lies in ruins. Empress, a young girl, wakes up in an underground research facility in San Francisco with no memories, driven only by a dream of Light House No. 8. She meets Norito and Miya, siblings scavenging for resources, and they travel to the surface together. Their journey is interrupted by an attack from Titan robot infantry units. Although Empress easily defeats the initial attackers, they face overwhelming numbers upon reaching the surface. Just as hope seems lost, Black Trike, a sentient motorcycle familiar with Empress, arrives to rescue them from the siege.
