During the shakedown cruise of the Guard Ship Amaterasu, the Henrietta Alliance of Planetary Nations suddenly declared war on the Planetary Nation of Kibi. The government, seeking peace, immediately surrendered and the entire crew was ordered to leave the ship. Conveniently all the officers on the ship except one went on ahead. The remaining crew (cadets, and one officer) decide to declare war on the Henrietta Alliance of Planetary Nations using the justification that they are a government in exile.
