Koza and Shiren in “Unfinished Business”

Do you think we did the right thing?

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]

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]

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.]
