Mili Hill is the princess of a poor country, and is doomed to become the 12th wife of a king who only wants to marry her in order to have her dowry. On the way to her marriage, the princess’ ship is attacked by the legendary pirate Harrid Kalid, nicknamed “the real king of the pirates”!
In order to ensure the safety of the people on the ship and to get out of her political marriage, Mili requests that she be able to board Harrid’s ship. In return, she’ll give him her dowry: a fragment of the “Stone of the Sea”. Legend has it that if all the pieces are assembled, then the stone creates a treasure map. Consequently, every pirate -- including Harrid -- wants it! Thus begins Mili’s high seas adventure with the king of the pirates!
