This Pirate Doesn't Play Fair

In the Azure World, 99 percent of the surface is covered by the "Sea of Mist," where countless "law islands" with different fantastical rules are scattered across the ocean. Humanity has built its last civilization alliance, the navy, upon the giant ship Ark.

Pirates are both plunderers and adventurers exploring the truth hidden in the mist. Legends say that if one gathers the seven "Keys of Truth," they can open the "Island of Origin" at the edge of the world and gain the power to rewrite the rules of the world.
