A good anime movie with enough action to keep you entertained through the story. The plot is simple but done well and the sword fighting is very entertaining.

But the quality is not so good so you maybe find a better version somewhere else.
The story is set in the Sengoku period. A rounin called Nanashi (meaning ‘nameless’) saves a young boy Kotarou at an abandoned temple. Kotarou has no family, is pursued by a mysterious militia organization from China and hires Nanashi as his bodyguard. Amongst the men who pursue Kotarou is a man called Rarou, a skilled warrior with blond hair and blue eyes. He obeys an old man called Byakuran and is a member of the Chinese militia. Unlike his companions in the militia, he isn’t serving any Emperor and just wants to fight with the strong.
