One Piece
Gol D. Roger dikenal sebagai "Raja Bajak Laut," makhluk terkuat dan paling terkenal yang pernah berlayar di Grand Line. Penangkapan dan eksekusi Roger oleh Pemerintah Dunia membawa perubahan di seluruh dunia. Kata-kata terakhir sebelum kematiannya mengungkapkan keberadaan harta terbesar di dunia, One Piece. Pengungkapan inilah yang menghasilkan Grand Age of Pirates, orang-orang yang bermimpi menemukan One Piece, yang menjanjikan kekayaan dan ketenaran yang tak terbatas dan untuk mencapai puncak kejayaan serta gelar Raja Bajak Laut.
Monkey D. Luffy, bocah 17 tahun yang menentang definisi standar tentang bajak laut. Mengikuti jejak pahlawan masa kecilnya, Luffy dan krunya melakukan perjalanan melintasi Grand Line, mengalami petualangan gila, mengungkap misteri gelap dan melawan musuh yang kuat, semua untuk mencapai kekayaan yang paling didambakan dari semua kekayaan, One Piece.
