In space history year 0375, the Esper and Imperial Plans failed thanks to the protection of Locke and Near.

Meanwhile, hackers Cassandra and Barcov revived the abandoned federal administrative computer, Elena, attempting to restart the Imperial Plan. Locke discovered their plot and set out to stop it, while the federal administration became aware of the abnormal activity and intervened. With the involvement of Run and Near, the chaos spread throughout the entire galaxy.
