Noriko and Agata are two individuals whose lives have been dominated by close contact with one another. Agata had seemingly forgotten how much contact until he connected the girl in his dreams to Nori, while Nori herself clearly remembers everything, and how the only one she really needed seemed to be Agata. They were an inseparable pair, until they weren’t. Now, with one episode left they find themselves on potentially opposing ends of the game board.
Hardly anything in his recent life has ever affected Agata as strongly as seeing his doll-ified friends. But it got him thinking, and he thinks a lot throughout the episode, something he hadn’t done much of before because he was too busy not having emotions and going with the flow.
Now he thinks he understands a little more how Chidori saw him, and why she always protected and defended him, and how much pain he caused her by being the way he was. He calls to thank her and apologize, which Chidori sees as a furtherance of his wider rejection of her.
The mayor is telling (not asking) Yamada and Urushii that Kizuna is kaput, but wants them to soften the blow of the news. Of course, we know Noriko will not accept any news of that nature: The Kizuna System has been, is, and will continue to be her life. Taking Kizuna is like taking that life away.
The two researchers, able to look back and realize their overeagerness to achieve results for a world that needed them desperately, acknowledge the collateral damage done to Nori as a result, and Yamada is determined to make up for that by granting all of her wishes. Urushii seems to agree. Without knowing it, they’ve become more than minders or underlings to Nori; they’re her friends too.
That realization seems to come to the former Kiznaivers as well—that they’ve been friends for some time now, without knowing it. It’s the reason they were able to get through all their trials so easily, and it’s why even though their pain is no longer connected artificially by Kizuna, they still feel pain in their collective hearts when Agata bears his to them on the rooftop.
That being said, they’re still incredulous, but when Urushii confirms they’re no longer connected, it’s hard to remain in denial: they have empathy for one another. Kizuna simply gave them the nudge in the right direction. Now these people who believed they could never have proper friends have friends.
But that’s not nearly enough for Noriko. After all, the world is full of conflict and rancor, all because people technically bear the pain in their hearts alone. Six people having the same emotions at once isn’t the same as being literally connected, via Kizuna.
Sensing the end of Kizuna is nigh without action, she gives an address to the entire town, announcing her intention to connect all of them, government and corporate interests be damned. This seems selfish on her part, and even paints her in the light of an antagonist, ready to impose her will on the masses.
But she is nothing more or less than what the system made her, and she’s not ready to give up on her ideal of a perfect happy future…whether anyone else wants it or not.
