Symphony of Steel

"We are always looking for additional performance data on the Empire of the Rising Sun's pilot-assisted combat robots, for the sake of our own research. The Imperial Commander Kenji, one of the men responsible for the Empire's new generation of fighting forces, is training a recently-awakened platoon of Steel Ronin here. This is a rare opportunity to observe these strange battle suits in action. Supposedly the men inside the Steel Ronin are violent Imperial war criminals, sentenced to a sort of solitary confinement..."
