Eiichiro Oda's pirate epic, running since 1997 and the best-selling manga in history. Monkey D. Luffy and his Straw Hat crew cross a world of mystical fruits, impossible seas, and nation-sized villains. The cast is famously vast and the aesthetic range — tropical beaches, neon-lit Grand Line cities, feudal Wano — makes it one of the richest source pools for AI illustration.
