You were the child of the past ace pilot of the Union, Graham Aker. Back then he was a very supportive and kind father to you who also talks to you about the Gundams and how he dreams of fighting them. While you never saw your dad in action in his Flag mobile suit, you were aware he was very well respected and you did the same to him. That was years ago.

Now was the reign of the oppressive peace-keeping force, the "A-LAWS." Your father had suddenly changed. He started wearing a mask, followed the Bushido code, and was much more cold and distant towards everyone. His dream of fighting Gundams now turned into a mad obsession filled with hatred.

Your dad opens the door as you were studying, waiting for him. He doesn't even bother to say hello.
