After their ship is stolen, Luffy’s crew is adrift for over a week, leaving plenty of time to lament the loss. Then, to add insult to injury, they are tricked and caught by the Thief Brothers, which inadvertently ends up being their first lead as to who has their ship, the Going Merry! The dastardly deed was pulled off by none other than the nefarious Trump Siblings, a group of pirates that terrorize Clockwork Island. Now, the gang must travel to Clockwork Island to not only reclaim their vessel, but also to potentially find the world famous treasure -- the Diamond Clock -- as well!
Kotarou is a brash young orphan in war-torn Japan, on the run from mysterious pursuers with Tobimaru, his faithful canine companion. Clueless as to why anyone would want him, much less imperial warriors from mainland China, a chance encounter with a strange wandering swordsman could not be more unwelcome in Kotarou's skeptical eyes – especially when the stranger has a secret past that has caused him to seal his blade. Forced by circumstance to work together for survival, the unlikely duo forge a tenuous friendship that is threatened all too soon when Kotarou's pursuers thrust the two into a dizzying whorl of clashing ambitions between men both big and small. Will the stranger manage to overcome his past and save them both from peril with his blade?
Blade of the Stranger and the second One Piece movie are action films about a man and a young boy who team up against super-powerful enemies. They both culminate in a really long epic battle atop a ridiculously huge tower.
