This is not a 12 Angry Men scenario, and it was never meant to be. By that I mean Kotoko’s goal from the start wasn’t to gradually chip away at Rikka’s influence in the forum. It was all about introducing enough elements of plausible fiction so that when she dropped her fourth solution—Nanase Karin isn’t even dead—the forum posters would take those previously posited elements and form their own theories about what happened.
Rikka meanwhile only intervened in the forum to reject Kotoko’s three conclusions, rather than those elements. To try to do more would expose her own motives to the forum. When she kills herself, she chooses the futures with the least dissenters, while Kotoko is all about creating more and more possible futures in which the Steel Lady is not real.
Kotoko’s fourth solution smartly utilizes elements of the previous three the forum have already been acclimated to and are comfortable holding in their individual minds. Nanase Karin was never killed by that steel beam; the faceless corpse was that of “A-san”, a woman of the same age and figure whom Karin befriended.
She convinced this A-san to help her escape the public eye by taking her place, but eventually murdered her by knocking her out and then dropping the precariously-positioned steel beams onto her face. After that, Karin took A-san’s identity and started a new life…but it wasn’t enough. She wanted to make certain the public believed she was dead, so she created the Steel Lady Nanase urban legend.
In order to quickly cement and spread that legend, Kotoko posits that Karin created the very Steel Lady Nanase Wiki on which everyone is chatting, and that she is currently among them. This is a stunning move that traps Rikka without ever revealing her true identity. The idea of Karin herself being the admin is seductive enough, because it draws upon the affection for Karin among many of the posters.
Finally, Kotoko explains how Detective Terada happened upon Karin, scouting out the scene of Steel Lady’s next appearance, quite by chance. When his detective instincts recognized her through her new appearance (her prodigious bust size being a dead giveaway), he is thrown off balance just enough to give Karin the opening she needs to kill him. None of this is airtight, but it doesn’t need to be, because much of the forum speculation is now on cruise control, as Kotoko planned.
Even though she continues to kill herself, Rikka finds herself less and less able to grasp the future she wants, in which the forum believes Steel Lady Nanase is a real ghost and not an artifice of her namesake. She seems to toss her blade away in disgust and resignation. Meanwhile, while she’s been choosing whatever futures had the fewest dissenters, Kurou has always gone for the same one over and over: the one in which he defeats Steel Lady.
As the “votes” start streaming in in MP Kotoko’s favor, Steel Lady becomes more erratic and uncoordinated, until Kurou is able to snatch her steel beam out of her hands and slam it into her face. Born from lies, she’s now poised to be destroyed by lies.
The truth, as Kotoko said, never had any place here. I can’t see what aces Rikka might have up her sleeves could undo Kotoko’s masterpiece of logical fiction, since it’s no longer about two dueling fictions, but the numerous fictions that exist in the imaginations of the forum. And by so carefully and artfully preparing this committee over the last few episodes, In/Spectre makes the final checkmate that much more satisfying. In short, it delivered the goods.
