A Federal Mecha, towering over five meters, is in combat with an Imperial Mecha within a testing area.
The Empire has yet to discover the location of the Number Nine Base, and this Imperial Mecha is a captured war trophy of the Federation. After undergoing repair and equipped with the Federation's developed automated driving system, it is simulating the most commonly-used combat tactics of the Imperial Mechas.

The charging Imperial Mecha raised its weapon, launching an attack at a speed difficult to evade even for a common Mecha Warrior.
