Years ago, a pirate captain executed one of his subordinates over a paltry sum of money. Now the subordinate's child has left the territory controlled by the pirate captain to seek a way to grow stronger on a remote island and take revenge. Along the way, the child finds care and affection from the island's leader and new companions, and gradually refines their revenge plan. Meanwhile, the pirate captain's descendants are growing up too, and eventually take the opposite side of the island. Fate plays a cruel trick on both sides, turning them into “partners” who must face everything together. But could the child of their enemy have the same person to blame for their father's death? What will become of the revenge plan already set in motion?
