Luffy, Zoro, and Nami find themselves adrift on their boat, lacking any provisions. Suddenly, a sea dragon attacks, capturing Nami. Luffy and Zoro end up washed ashore on a small island, where they meet a girl named Medaka. She reveals that Pirate Ganzack and his crew have taken control of the island, forcing all the men, including her father, into slavery. Determined to rescue her father, Medaka is willing to do whatever it takes. The situation is further complicated by a severe food shortage on the island, much to Luffy’s dismay. However, he discovers that defeating Ganzack could lead to an abundance of food. Consequently, Luffy, Zoro, and Medaka decide to infiltrate Ganzack’s stronghold to liberate the captives, rescue Nami, and overthrow Ganzack.
