In a key early scene that informs the torrent of revelations to come in the on-the-nosely-titled “Truth”, Aiko weeps for the loss of Shinomiya, something for which Shiraishi is very grateful, despite the fact she doesn’t blame Aiko for the loss.
We also learn that Kanzaki essentially leaves the remaining Divers no choice but to press on, questioning whether they took the risk to their lives seriously when they signed up for a mission they knew they might not return from.
Sagami curses Kanzaki’s cleverness, but the kid has a point: they signed up for this. That they were lied to about the details doesn’t change the fact that taking the job meant being prepared to die from the start.
From there, “Truth” unfolds pretty much like the previous episodes, with the team storming through the next zone to get to the next gate…only this is the final gate before Primary Point, and they no longer have a Beetle to protect them from the big stuff.
Thankfully, and somewhat surprisingly, however, a “benevalent” purplish version of the Matter protects Aiko & Co. from the malignant red Matter int he nick of time, in the process sending Kanzaki and Aiko flying like Renton and Eureka.
But once the group enters the facility where Aiko’s still-incomplete operation took place—and where the Burst began—the end of their journey also marks the end of the episode’s momentum. For the balance of the episode, revelation after revelation is made, thanks to Dr. Isazu remotely talking to Aiko and the others from the facility’s P.A. system.
Much of what he says, we already know: that Kanzaki is really Yura, for instance. Some of the news is, well, new: the “Aiko” we’ve followed all this time wasn’t the one with the real brain after all, but AICO, the elaborate artificial brain occupying the carbon nanostructure-repaired real body of the real Aiko—both built by Yura.
Yura intends to merge the fake Aiko’s brain and body to end the burst, which will also destroy the near-as-makes-no-difference sentient life form he created. No other possible solution is brought up; Isazu simply informs Aiko that the SDF will soon pummel the facility she’s in, so she’d better find cover.
Because so much information is dumped on us, some of which repeats what’s already been revealed to us, things get really stagnant in the latter chunk of the episode. Switching from the facility to the hospital where Isazu is to the hacker’s house where Kurase and Nanbara are only feels like a naked attempt to break the infodump up among different settings, and it doesn’t really work.
The slog is somewhat interrupted when the red Matter arrives, and rather than stick with Kanzaki/Yura or the Divers, Aiko runs off on her own, gets cornered, as is once again saved by the purplish Matter, in which an inviting, brightly-lit opening is formed. When Gummi goes in, Aiko follows, and before she knows it she’s face-to-face with “the other Aiko”, the one Isazu says is the real deal.
Does this mean Isazu’s daughter is controlling the red Matter? What are the two Aikos going to discuss? Is there any way to end the Burst and save Japan from destruction without destroying the artificial body that apparently started it all?
