The Japanese Defense Force could not go to War. It was not in their cute and friendly nature, so Ken Banno and those who followed him volunteered to join the American military. Most followed their Japanese traditions of painting their weapons in cute colors. Ken often had some pretty anime pop idol, a smiling Pokemon, or some other utterly ridiculously cute and brightly colored thing painted on his fighter. And he usually based his fighter or weapons in bright pink or yellow, just to drive home the point that he was a warrior against his better nature. There was one thing in all that time that he demanded of the American military. Something it never would have considered if he had not spoken up. The American military kept the records of their Japanese volunteers sealed against all requests. Ken wanted his people to be able to return home without their deeds being known to all.
