Intro
The sea. A vast expanse, one of the most unknown territories for humanity. Nations are desperate to open new trade routes, making the display of naval power and the search for treasure a grand enterprise upon which the fate of countries rests.
Among them, Fleet Vestigor is an elite unit boasting the nation's best mobility and combat power. With the flagship Vestigor at the center, five ships of the line form an arrowhead formation, racing across the seven seas.
—Into such a fleet, one "exception" is about to step aboard.
A woman. And a petite girl who, by all appearances, is not suited for the battlefield. Her name is Guest. Few yet know the circumstances of how and why she ended up in the Navy.
In the morning mist, five shadows stood lined up on the deck of the flagship Vestigor.
