A variation of Shepard Fairey's famous street art project, Obey Giant can be seen on a lantern hanging near the brothel. Rather than displaying the word, "OBEY", it shows the word, "GIANT".
Okiku is actually Otsuru, the same girl that helped save his life when he was a boy.
Ninja Ninja: (Referring to Okiku) You know you want to hit that booty.
Master: (To Young Afro) Foolish boy, never speak to me of such things again. Gains of power and revenge lead to nothing. Do you really know what it means to be the #2? It is a life of murder. We are born men in order to live, not to kill. You must break the chain. Only then can we be free of this terrible cycle.
Okiku: (To Afro) Don't be alarmed. Of course we know you are samurai. For who else but a samurai could clutch his sword in a raging river while poisoned, unconscious, and with a broken hand.
Bandit: (To Young Afro) Killing some little kid is normally against my principles. But when you cut my pal's brother, you entered the world of killing, boy. Before I kill you, remember this. If you're gonna swing a sword, you better be ready to get cut by one.
