第 12 集: 首席沃克釋放琪琪,製造連環殺手韋爾斯以困住眾人心智,同時推進其宏大的調查計畫。

Chief Hayaseura/John Walker releases Kiki in the police department building. Everyone she comes in contact with is put in a deep sleep, including the investigation team, with their minds transporting into one of the many serial killer id wells seen in the previous episodes. Chief Hayaseura enters the Kura cockpit room containing Narihisago, Hondomachi, and Fukuda. He admits he created the Kura system to catch serial killers and has been very pleased with the results, brushing off his creation of serial killers as a minor side effect of his greater cause. His goal is to turn all of Kura into a giant Mizuhanome to allow for larger-scale investigations. He then enters a Kura cockpit and commits suicide, allowing his mind to continue living and working in the Well world. Narihisago and Hondomachi enter the other cockpits to go after him, while Fukuda falls into a deep sleep invoked by Kiki's presence. After creating multiple serial killer Wells and entering and exiting Kiki's mind so much, Walker now shares much of Kiki's unconscious, and is able to freely teleport to different Wells Kiki has been a part of. Narihisago and Hondomachi chase Walker through multiple id wells. Walker reminds Hondomachi of her real identity to trap her in a Well storm, but she is rescued by Fukuda, who used his arithmomania to track her down. However Fukuda sacrifices his life to protect Hondomachi from Inami, who tracked down Hondomachi to exact revenge for the death of Kazuta. Inami leaves to another Well to see Kazuta, but is murdered by John Walker. Meanwhile, Momoki and Matsuoka surveil Kiki from outside the department building. They obtain Nishio's prototype Mizuhanome helmet, and the episode ends with Momoki putting on protective gear as he prepares to approach Kiki. (Source: Wikipedia)
