One Piece: His Majesty's Infinite Debt of Gratitude

When pirate fleets storm the harbor, Lynn dispatches the Uchiha clan. When three Marine Admirals launch a Buster Call, he sends the Eight Demons to test their Logia powers. Kaido and Big Mom attacking together? Aizen and the Espada will handle it. As the World Government mobilizes its entire military force, Lynn remains unfazed—because behind him stands an empire of legendary warriors from countless worlds, all bound by an unrepayable debt to their sovereign. In this One Piece world, one ruler commands forces that transcend dimensions themselves.
