A band of samurai set out to avenge the death and dishonor of their master at the hands of a ruthless shogun.

Kai: I will search for you through 1000 worlds and 10000 lifetimes!
Mika: I will wait for you in all of them.
Shogun Tsunayoshi: For the crime of disobedience, you should all be executed as common criminals, but you and your men follow the old ways of Bushido, to honor your lord and avenge treachery. I see only samurai before me.
Ôishi: No one, but you and I, can know that you are, and will always be, the joy of my life.

Should a samurai ever lose of fail his master, he suffers the greatest shame in all Japanese society. He becomes a ronin. And yet, to know they story of the 47 Ronin, is to know the story of all Japan.
Yasuno: [to a bowing Kai] I would rather have been killed by that beast than be saved by a half-breed.
