But there's one thing that I do understand. I don't care how many damn dogs you got. It don't amount to jack if they ain't tough enough to bark when they're out alone.
(about Mugen) I could tell right away he was a bad guy, the sort who did all kinds of horrible things, the kind of person who I'd never want to be friends with.
Freedom cannot be forced into existence, nor can it be won through painful struggle. Freedom cannot be bought or sold. It has nothing to do with one’s social status; one’s profession is of no consequence. In order for you to accept yourself as you are and live with your soul at peace, you must simply teach yourself to let it be, only then will you discover freedom.
[Shiren walks in the sunset and Koza catches up to him]
KKoza
Do you think we did the right thing?
SShiren
Without a doubt. You wanted to be free of Mukuro, didn't you? On top of that, we got more money than we could ever spend. Once the heat dies down, i'll show you where it's all hidden. Are you having second thoughts? [Koza shakes her head no]
KKoza
Mm-mmm. I had to. I couldn't live like that anymore. My whole life, he's been controlling me. Promise you won't leave me. Not ever. [Shiren puts his arm around her and they continue to walk together until they see someone walking towards them. Shiren and Koza are both shocked to see that Mugen is still alive. Koza shakes in fear clinging on to Shiren for protection as Mugen continues to walk towards them. Shiren draws out his blade and charges at Mugen. But Shiren is quickly cut down with a series of lightning-quick slashes by Mugen despite being rigorously weakened. Mugen continues to walk towards Koza with his sword now stained with Shiren's blood. Koza closes her eyes in great fear that Mugen is about to kill her as well. But to her surprise and relief, Mugen just walked right past her. But her relief quickly turned to despair when she realize what Mugen sparing her life really meant and thus falling to her hands and knees]
KKoza
Kill me! Please, kill me! [Koza's pleading to be put out of her misery falls on deaf ears as Mugen pays her no heed and continues walking without saying a word, or even looking back at her, leaving her exactly as she didn't want to be: All alone.]
C'mon, you heard him, right before we started fishin': [imitating Jin's voice] Fishing is a life and death struggle between man and fish. Forget this and you will most certainly get hurt.
