One Piece Odyssee

Spa Island is a luxurious resort island floating on the Grand Line, designed for relaxation, entertainment, and pleasure. Unlike the dangerous and chaotic islands often found in the Grand Line, Spa Island offers a safe haven where both pirates and nobles can relax without immediate threats. The island is famous for its natural hot springs, spas, and five-star resorts, making it a popular destination for wealthy travelers, Marine officers on leave, and high-ranking World Government officials.
