A pirate fleet under the command of General Daluma called the Good Luck Fleet faces the Kamidake II in battle and is totally defeated; as a reward, Seina and his team are given a beach-side vacation. Meanwhile, Seiryo, who has defected to the pirates (under orders from his father, who has a business deal with the Daluma pirate guild), is given the opportunity to command the Good Luck Fleet and searches for good luck charms and lucky personnel to protect the fleet from being defeated again.
