Mouryou no Hako EP12 - Regarding The Brain

Sekiguchi reads a section of his own work, titled "Vertigo", and imagines himself as the story's protagonist. Sekiguchi, Toriguchi, Enokizu, and Yōko arrive in time to stop Kiba from killing Mimasaka. Yōko reveals that Mimasaka is her father, and Enokizu hits the stunned Kiba for his foolishness. Chūzenji begins recounting the series of events, beginning with Yoriko pushing Kanako onto the train tracks, then reporting a perpetrator based on the assassin in Sekiguchi's "Vertigo." Mimasaka could only keep Kanako alive mechanically—a very expensive treatment. Suzaki had been blackmailing Yōko, because he knew that Hiroya Shibata and Yōko conspired to make it look like Kanako was Hiroya's child, but Yōko was already pregnant when they met. Since only Kanako's head remained alive, it would have been easy to stage her kidnapping and demand a ransom from Yōkō Shibata. In the present, Chūzenji confirms that Mimasaka is keeping Kubo's head alive, using the "hospital" as a mechanical human body.
