In the vast and strange sea where magic and science intersect, the "Wave Chaser" pirate team led by Lake Vane and Philmar Seco embark on an adventure to pursue dreams and freedom. Multiple stories are intertwined, and the brotherhood among the members coexists with their secret past happiness, but it is also full of betrayal and temptation. They spanned giant floating islands, technological cities, and primitive magical tribes, experienced humorous incidents, escapes, and strategic battles, and gradually discovered the truth of the global battle surrounding the mysterious sea map, as well as the ultimate test of freedom and friendship. After separation and reunion, everyone made their own choices about freedom and friendship during the adventure and growth journey in the finale.
