One Piece: Nanatsu Shima no Daihihou

About

This Game Boy Advance RPG follows Luffy and his crew after a storm scatters them across a mysterious island. Each character explores separately guided by a talking bird that helps them regroup. Battles against the Simon Pirates use standard turn-based mechanics with party members having distinct roles. The story sticks to basic anime tropes as the crew faces off against the pirate gang through scripted encounters and randomized fights. Released in 2002 by Banpresto this title only reached Japanese shelves. It offers straightforward RPG gameplay with familiar One Piece character designs but lacks deeper customization or branching narratives. The 20+ hour campaign includes side quests and basic equipment upgrades typical of early 2000s handheld games. No official follow-ups or international releases ever materialized.
