For the 73rd class of cadets of the Defense University of the small planet Kibi, a maiden voyage on the new warship Amaterasu is a fitting event just before graduation. As they are returning home, however, they are shocked to hear news of a declaration of war by the aggressive Kingdom of Henrietta against Kibi.

When the Kibi government surrenders without a struggle, the cadets decide to fight back using the Amaterasu, with funding from the Galaxy News Network. The only stipulation? Exclusive airing rights to the action and good ratings. So, the cadets find themselves the “stars” of their own reality show.
