The one who knows you best is often not yourself, but your enemy.
Once an opponent of the "Lord of the Sky," "Eagle King" David Sid's lifelong wish, or rather obsession, has been to defeat that arrogant young man.
Time has changed things, and "Eagle King" retired from the Federal Air Force. Unable to withstand the grind of time, he turned into the white-haired Old David. This difficult wish is likely to be taken to the old coffin with him.
However, it didn't stop him from passing on the research targeted at the "Lord of the Sky" to the new generation.
