The Fortis Kingdom was an empire that had just been founded in 1520 in the New World's ocean region. The Fortis Kingdom had a King who still had a very young age. However, even though the King is young, the King has commanding abilities, high intelligence, and a good personality toward others.

When this Kingdom appeared to the world, many powers want to dominate this kingdom, especially the World Government and some of the great pirates residing in the New World.

Then? How's the story going?

Hoping to reach closer to the many answers that plagued her mind.
