One night, three months after the previous fight. . . .

In the city of M in western America, the skies' darkness was torn to pieces by a strange, speeding flash. And at that moment, many gigantic aircraft arrived. When the townspeople looked up at the outmoded fuselages, they didn't see that something was scattered from the airplane. . . .

Then everyone saw, falling with parachutes, many soldiers and combat vehicles who consequently gained complete control of the town.

Similar incidents happened worldwide in every country. One country received a battleship's gun fire on the open sea; another was devastated by a tank unit that suddenly appeared in the forest. Strangely, each invasion used a weapon like those from World War II.

Even the base of the secret rescue team who protected world peace in shadow was attacked by the mysterious flying corps. The team's fighter planes flew away and were burned up promptly, one after another. The base was immediately devastated. Hardly any of the most powerful and technologically-advanced machines were left, the electronics did not work completely, and the anti-artillery systems were completely broken. The enemy used inferior, outdated reciprocating engine aircraft. Furthermore, even the experimental fighting bombers were included.

Commanding officer Lord River received the report and, after a moment of silence, gave his decision. "Strike, making use of all active weapons. You also have permission to use the old weapons in the underground storage hangar."

This latest mission was regrettably troublesome. I appreciate your participation.
