What happens in Episode 12?
In PopRot summary, “Reincarnation” uses the compact ONA format to move Aiko from confusion toward a clearer understanding of why the mission cannot be treated as a normal rescue trip. At ALSUS, Kanzaki, Aiko and Kazuki find the Matter has engulfed the facility. Aiko prepares to sacrifice herself to destroy the Burst, but Kanzaki has a change of heart, accepting that she is the real Aiko, too, and swears to save her. As Kanzaki inserts Aiko into the Matter for the brain transfer, Isazu activates all of the Yuzuha duplicates to attack her. The Divers fight to protect Aiko during the brain transfer surgery, but it is a losing battle until they fire an Anti-Cell Assembler capsule onto the Matter, while back at Kiryu Hospital, Kurose severs the link between Yuzuha and her duplicates. This has the effect of shutting down Isazu and the Matter, returning Yuzuha to consciousness. Kanzaki completes the brain transfer, and the original Aiko emerges from the Matter, greeting the Divers for the first time. The duplicate Aiko, still trapped inside, frees Aiko’s mother and brother. As the Matter slowly crystallizes, a creature crawls out, transforms and finally a regenerated Aiko emerges. Kanzaki assumes that Gummi who was trapped inside the Matter with her had a copy of Aiko’s body data. The two Aikos embrace, then the duplicate Aiko goes to greet her family, before swapping places with the original Aiko. Life returns to normal for the original Aiko, while the duplicate leaves to live her own life, and create her own name and memories. The important thread is not just the immediate danger, but the way each decision narrows the route toward the Primary Point and forces the team to weigh containment, survival, and Aiko’s identity.
Detailed discussion
The episode works as one step in a continuous route through the Kurobe Gorge crisis. Aiko’s personal stakes stay tied to the larger biotech disaster, while Yuuya and the adults around the mission reveal information in controlled pieces. The result is a steady escalation: every stop changes what the team knows about Matter, artificial bodies, and the cost of reaching the center of the Burst.
