Fuu, a waitress who works in a teahouse, rescues two master swordsmen, Mugen and Jin, from their execution to help her find the "samurai who smells of sunflowers."

Mugen: When you point a sword at someone either you kill them or they kill you, there ain't no inbetween. So quit talkin' like a fuckin' pussy. Anyone who can't handle that should just SHUT THE FUCK UP and GET OVER IT!
Kagetoki Kariya: This flower is an example of a beautiful exterior masking its true intentions. Intentions that are really quite brutal.
Fuu: [Mugen takes Fuu's coin and flips it high into the air] Uhh, don't you think you tossed it a little far?
Jin: He doesn't understand the meaning of "restraint."
Mugen: Kiss my ass.
Mugen: Forget all that formal crap 'bout comin' at me one at a time. I'll take all you bitches on!
Mugen: Kiss my ass
Kagetoki Kariya: Only hope can give rise to the emotion we call despair. But it is nearly impossible for a man to try to live without hope, so I guess that leaves Man no choice but to walk around with despair as his companion.
Mugen: Huh? What the hell do you want?
Kagetoki Kariya: If you're looking for Kasumi's daughter, she's crossed over to the island.
Jin: Do you know him? You know Seizo Kasumi?
Kagetoki Kariya: I know he's a felon who abandoned his country and had his soul stolen by that foreign religion. I've heard that he fled here to Kyushu and that he was involved in the Shimabara Rebellion. I also know he's the man that the Shogunate wants eliminated more than anyone else. They've know all along that his daughter was trying to find him. In fact, it's helped them. They've let her run free this whole time so they're able to discover Kasumi's whereabouts. And now, although it pains me to say this, I have to insist that you two die right here.
Mugen: You're taking us on by yourself? You sure got a big pair on ya, pal.
Kagetoki Kariya: [readies his sword ] Come, I hope that you don't disappoint me.
Sara: What I can't see I can sense.
Mugen: [stumbling, bleeding] What?
Sara: Inside of you looms a simmering storm of hatred and rage, but perhaps what I'm actually sensing is sadness. It's as if you've never once been loved by anyone; it's as if you're just like me.
Jin: [after Mugen starts a fight with the authorities in a tea house] Why do you always find it necessary to stir up trouble?
Mugen: [shrugs] Can't help myself. Besides, guys like that put a bug up my ass.
Shige: "There were men on top of horses and horses on top of men, piled one atop the other. The valley was laid open before the men. Its depth was great and wide. But the number of soldiers that died that day would line its two rock walls from side to side. Corpses stacked up to build a mountain of death and it gushed rivers of dead men's blood." The Tale of Heike, Volume seven, Descent into Kurikawa.
Jin: You're the lowest of the low.
Mugen: What'd you say?
Jin: Your stance leaves you wide open, and your moves are totally inefficient. All in all, your fighting style is a mess.
Mugen: You son of a...
Jin: I swear, you are the most undisciplined fighter I've ever known...
Mugen: Shut your damn mouth!
Jin: ...and the only one I wasn't able to kill.
Jin: [Confronting the Yagyu guards as they are about to dispatch an innocent peasant] To serve your lord and do his bidding, is that honor?
Yagyu badass: [scoffs] Of course it is.
Jin: Even if that lord is an unimportant piece of shit?
Yagyu badass: [the Yagyu draw their swords to attack] What the? Watch your mouth! Don't try to interfere!
Jin: Cutting down a man who's done nothing wrong; is that what you spent all that time honing those skills for?
Jin: In my opinion, you're worthless.
Yagyu badass: [rushes at him] Screw You!
[Jinn kills all three Yagyu guards with his sword]
Mugen: I can take all you bitches on!
Fuu: [Mugen and Jinn are about to fight] Alright, enough you two! You two made me a promise. You haven't forgotten, have you? Until we find "the Samurai who smells of Sunflowers", you two are not allowed to kill each other!
Mugen: Oh yeah, this smelly guy, I been meaning to ask ya about that.
Fuu: Huh?
Jin: Who is this "Samurai who smells of Sunflowers"?
Mugen: And what the hell is a sunflower anyway?
Jin: You don't know?
Fuu: It's a flower!
Mugen: So, what do they *smell* like?
Jin: [Both turn toward Fuu] Do you have any other leads?
Mugen: Like a picture or something?
Jin: What makes you think he's around here?
Fuu: [confused] Well, uh... wait a minute!
[her stomach grumbles]
Fuu: For right now, let's just find something to eat, kay?
Mugen: [after finding a bag of coins in the river] We hit the potjack!
Fuu: That's jackpot!
Mugen: All I know is we're filthy bitch!
Fuu: Filthy rich!
Jin: I hope your doing that on purpose.
