Id:Invaded

Synopsis

Two years have passed within Kiki's id well, with Narihisago spending this time leading three other serial killers to commit suicide and trying to investigate John Walker. While visiting the hospital one day, Narihisago and Momoki find Kiki's mind being researched by Nishio Shirakoma, the creator of the Mizuhanome System, however Narihisago does not recognize him. Kiki's health has deteriorated over time, and she theorizes her body will disintegrate and fuse with reality, warping the structure of the world. She begs Narihisago to kill her, but he strongly refuses and stops visiting her. Kiki mysteriously disappears from the hospital a few months later. Narihisago goes to kill off the Perforator, but instead runs into Hondomachi. This meeting between two different Well divers creates a rift, and Kiki's Well world slowly begins to dissolve. Additionally, Sakaido's ten minutes in the Well end, and Anaido initiates his extraction. Before he leaves, Narihisago gives Hondomachi a notebook of his findings to continue investigating John Walker. Back in Momoki's Well, Sakaido realizes Anaido has tampered with evidence on Kaeru's body, purposely diverting the investigation. Anaido/Fukuda reveals he is immune to amnesia due to his drill injury and has remembered the real world this whole time, intentionally sidetracking the investigation team. He reveals the corpse in the quicksand belongs to Narihisago, and that they are actually in Narihisago's Well, not Momoki's. By making Sakaido remember his real-world identity, Narihisago's mind creates a storm to protect his conscious from his unconscious. The episode ends with Narihisago seeing an image of John Walker in the storm.
