Nori has gone over the deep end, driven by the convictions she’s been developing since the Kizuna System was begun. It’s a flawed philosophy that everyone will be hunky-dory if only they shared each others pain, with her specifically.
She’s not going to stop, so it’s up to Katsuhira to stop her by setting the record straight about just what friendship and love are and what causes them (hint: not the Kizuna System). Nico leads the rest of the Kiznaivers in backing up Katsuhira.
What seemed to be a far larger-scale operation, with the power going out, the bridge retracting, a random explosion, and Nori’s plan to connect everyone, turns out to be a lot smaller in the end: Nori on top of the bridge, Katsuhira climbing up to meet her, and a long and emotionally pitched conversation about why she’s wrong and should let go of the pain.
Whenever Nori counters one of Kacchon’s arguments, either Kacchon or one of his friends has the answer. The Kizuna System didn’t make them friends, or make Kacchon fall in love with Nori; it was merely a facilitation; a nudge in the direction of one another.
After that, even after they were disconnected, the Kiznaivers cared about each other, what they thought, and even if they didn’t quite understand immediately, sought to understand, even if it caused them emotional pain. Nori doesn’t need Kizuna, and she never did; she just had to learn what it was to truly be friends with someone, something she never had the opportunity to do.
Because she was alone before Kizuna and not alone after, she made the corrolation that Kizuna could cure all the ails of the world. But it’s not that simple. Honoka puts it best: it’s not a constant connection, but a constant cycle of distancing out of frustration and coming together due to new epiphanies about one another. The former Kiznaivers aren’t friends in spite of no longer sharing each other’s physical pain, but because of it.
Once Kacchon reaches Nori, headbutts her (accidentally or not), and they go into the drink, the resulting plunge is a kind of new revelation for Nori. Now, at last, she can start letting go of everyone else’s pain, knowing they won’t disappear.
Indeed, post pain release, her painless friends start to gradually “wake up” from their catatonia. Thankfully, the episode does not go into excruciating detail abotu the exact mechanism whereby Nori makes all this possible, but suffice it to say she’s on the right track now.
Just as gradual but steady will be the other Kiznaivers and how they interact with one another. Honoka seems willing to give Yuta a try (or at least tease him about it), Chodori has to admit she’s been thinking about Tenga a lot lately (to his delight), and Nico is willing to play the long game against Chidori for Tenga’s heart, cheered on by Hisomu (who likes the sound of that potential fistfight).
As for Nori, she didn’t get as messed up by the fall off the bridge as Kacchon, but there’s no doubt it was a transformative experience, asking Kacchon what he’s thinking (because she doesn’t know), smiling, and possibly even preparing to lean in for a kiss—until the rest of the gang bursts in.
PDA aside, that gang seems willing to bring Nori into their circle, and it’s Honoka of all people to recover the photo booth photos they took together. Nori notes the add-on special effects that make them look more cartoonish; one could say the same of her now-discontinued Kizuna System and its army of Gomorin.
While such embellishments, be it to social experiments or photos, can be fun, there’s nothing like the genuine article. Genuine faces, genuine emotions, genuine friendships, and genuine love. Nori has gained far more than she lost.
