KOS-MOS uses force to stop the cargo passenger ship Elsa and board the cargo bay. At some point, the passenger Cyborg Ziggy was attacked. Shion, who was also recovered, stops, but Ziggy and his protected MOMO, strangely, were destined for the second Mircia, the same as KOS-MOS. Because all of them have the same interests, Elsa rushes into hyperspace, aiming for the Milcia solar system. But soon, a mysterious armed battleship attacked there.
