Their plight attracts the attention of three captive children, led by Amanda, daughter of a renowned treasure hunter. Amanda offers a pact: aiding their escape in exchange for a share of a legendary treasure's riches she knows of. With newfound allies, the group narrowly flees to an isle where they encounter Luffy and his crew. However, their respite is short-lived as they fall into the clutches of the Bayan Pirates, relentless seekers of the same treasure. As Luffy and his comrades clash with the Bayan Pirates in pursuit of the hidden wealth left by Amanda's father, Amanda's disdain for adventure and riches begins to unravel, revealing a deeper connection to her father's legacy.
