Psycho-Pass - Season 2

An explosion occurs in broad daylight and despite having no casualties, it brings the attention of the MWPSB. The police's investigation tracks the culprit as Akira Kitazawa, a demolitions expert whose career was staggered after it was confirmed that his Crime Coefficient tends to increase under pressure. Upon locating Kitazawa's hideout, Inspector Akane Tsunemori realizes that he is setting a trap for them and disobeys her orders to advance and confront him. Her assumptions are proven correct, and Kitazawa escapes, apparently taking a female hostage with him, which he soon after releases. Certain that the hostage is actually a hologram with another trap, Akane's unit keeps pursuing Kitazawa and upon cornering him, Akane notices that his Crime Coefficient is just a little over the minimum required for the Dominator to enter into execution mode and decides to calm him down instead of killing him. Her plan works and she knocks him out with the paralyzing mode when his Crime Coefficient drops to the non-lethal levels. Elsewhere, Inspector Mizue Shisui and her partner Enforcer Yamatoya are sent to follow the hologram, who is revealed to actually be a man. This man does not register on her Dominator, and he injects Inspector Shisui with some kind of drug that paralyzes her. He kisses her, then takes her hand and makes her use her Dominator to kill Yamatoya, leaving behind the message "WC?", written in blood.

While trying to determine the meaning of the "WC?" message, Akane goes with Enforcer Sakuya Togane to interrogate Kitazawa, who claims that someone else helped keep his crime coefficient down and was responsible for the fake hostage, though another inspector, Aoyanagi, does not believe this to be true. Later, as Shion and Enforcer Sho Hinakawa learn that the fake hostage was an elaborately detailed hologram modeled after someone who died years ago, Kitazawa's crime-coefficient suddenly drops below that of a latent criminal, resulting in him being transferred to a general medical facility. Shortly afterwards, Akane discovers another "WC?" message scrawled in her apartment, before being alerted that Kitazawa had attacked Aoyanagi and escaped, believing that his claimed assistant was the one who set up his escape route. Kitazawa is cornered by Akane's group, uttering the name "Kamui" before he is eliminated by Aoyanagi, his last words leading Akane to realize that "WC?" actually stands for "What Color?".

Somewhere, Shisui finds herself strapped to a chair with her Dominator pointed towards her, her eye taken by her kidnapper, Kirito Kamui. As her fear causes her Crime Coefficient to rise, Kamui uses a peculiar method to suddenly bring it back down. Meanwhile, Akane and the others investigate the message that had appeared in her apartment, with no evidence that someone had broken in, leading some to believe Akane may have done it herself. On their way back, Akane visits Jouji Saiga, who had turned himself in after helping out Kogami during a previous incident, for his thoughts on the case. Later, Akane speaks with Bureau Chief Joshu Kasei, who gives Division 1 authority to look into the case and tells her to be cautious of Togane. As Akane begins her investigation, her partner Mika Shimotsuki becomes distrusting of Akane's actions, arresting a man named Kotoku Masuda who claims to know Kamui. Meanwhile, Aoyanagi, who had been contacted by Shisui and told to go to a mental care facility, finds herself lured into a trap by someone who violently attacks her whilst still maintaining a low Crime Coefficient, also mentioning Kamui's name.

Akane attempts to interrogate Masuda about Kamui, but he claims not to know him. Meanwhile, in the medical facility, the man has his hostages stripped and starts killing them one by one to raise their stress levels, claiming to be a savior in the name of Kamui. Aoyanagi manages to retrieve her Dominator, but discovers the culprit is still below enforcement level while the hostages are above, claiming to have had "eustress deficiency", believed to be an urban legend. After having Saiga look at the equipment Masuda used prior to his arrest, Akane theorizes that Kamui is somewhere within the medical facility, believing that he is somehow able to use Dominators. When Division 3 is sent to take over from Mika's group, Aoyanagi manages to take the culprit by surprise and undo the locks. However, she and all the other hostages are killed by Division 3 as a result of their high Crime Coefficients, while the culprit is also executed after bidding farewell to Kamui, who had learned that inspectors can also be judged by Dominators. Arriving on the scene to find a bloodbath, Akane discovers what is left of Aoyanagi and yet another "WC?" message.

It is revealed that Kamui, who now has Shisui under his will, is using her eye in order to wield a Dominator. Meanwhile, as the MSWPB investigate the crime scene, Mika spots Togane checking up on Akane's Crime Coefficient. The next day, as new enforcers are brought in, both Division 1 and 3 are sent to investigate a drone warehouse, where Akane and Togane discover a hidden area behind a holographic wall, finding masks of people's faces and another WC? message. Just then, the drones in the factory start activating and shooting down innocent, unknowingly being controlled by people playing a "Hungry Chicken" mobile game. Meanwhile, as Jouji is tasked with interrogating Masuda, deducing from footage of his speeches that he is in fact a different person entirely, Mika investigates Togane's quarters and discovers an obsessive amount of files and photos of Akane.

Shion manages to determine the drones are being remotely controlled by unaware citizens playing the "Hungry Chicken" mobile game, which Akane believes to be connected to Kamui's messages. While Shion works to prevent the game from being spread any further, Akane realizes there is someone with a Dominator targeting enforcers that stray from their inspectors, learning that Kamui's true mission is to retrieve Dominators. Akane decides to pursue whoever is wielding the Dominators, managing to take out most of the drones by exploiting their weakness. When the game hacks into police drones instead, Shion and the other uses a program to hack into the game's cloud server and show all the players what they were really doing, despite Mika's objections that it would raise everyone's Crime Coefficient. Akane soon confronts Kamui, who escapes with Shisui when Akane prevents Togane from using a traditional gun against him.

As Mika's group handles the aftermath of the incident, apprehending those that were still playing the game regardless, Akane tries to determine Kamui's motives behind obtaining Dominators, finding Togane to be a lot like her old partner, Shinya Kogami. After checking up on her grandmother, Akane confronts Kasei on why she hasn't deactivated Shisui's Dominator privileges, deducing that Kamui is someone that Sibyl has decided cannot be integrated into their network of brains. Meanwhile, Mika looks up Togane's background from files obtained from his computer, learning all of the inspectors he had previously worked with became latent criminals and were executed, unaware that Togane has found out she raided his room. As the group get together to examine evidence found in Kamui's hideout, Hinakawa discovers Kamui had used a hologram during the clinical incident which, along with the earlier hologram from the first incident, was also taken from a child who died in a plane accident 15 years ago, which the group discover Kamui was the only survivor of. Akane apprehends Yohei Masuzaki, a surgeon who previously operated on Kamui and is in cahoots with him, and has Saiga interrogate him, while Mika decides to investigate on her own after discovering the link to Masuzaki's medical files may be linked to Togane's corporation. After Hinakawa creates Holograms of all 185 victims of the plane crash, the group discover Kamui has dozens of followers right underneath their noses.

Masuzaki explains to Saiga how Kamui received parts from the other 184 bodies in his surgery, including seven brains, resulting in him becoming someone who cannot be measured by the Psycho-Pass, going on to explain that Kamui's goal is to overturn the entire Sibyl System. Meanwhile, Mika, who had been investigating Togane Foundation's patent on the surgery, learns that Kamui had last accessed the file before her. Looking over Masuzaki's testimony, including how he killed people of influence and replaced them with imposters, Akane and the others deduce that all of the 184 holo victims are Kamui's personas, while the imposters that were used as replacements were illegal immigrants. Mika discovers the patents owned by the Togane Foundation were filed by Togane's mother, Misako, who died five years ago, believing Kamui's goal may be to get revenge against the Togane Foundation. Mika tries filing a report to Kasei have Akane dismissed from the MSWPB, feeling she is a danger to the operation. However, this turns out to be a trap laid out by Kasei, who is revealed to be Misako Togane herself, who decides to use her as a test subject and show her the truth behind Sibyl.

Having revealed the truth of the Sibyl System to Mika, with her hue remaining clear, Kasei and Togane, who was an artificially created human, decide to use her for the purpose of turning Akane's hue black. After eliminating Masuzaki, who knew too much about Kasei's identity, Togane tasks Mika with locating Akane's grandmother, Aoi. Meanwhile, Akane and the others learn of an official named Koichi Kuwashima, one of Kamui's friends who had escaped the plane accident, who at that time helps Kamui exact his revenge on a company who benefited from turning a blind eye to the incident. When Akane and the others arrive at the scene, which had already been set on fire, Kuwashima gives Akane a box containing Aoi's ear, angering her. As Saiga interrogate Kuwashima, Kamui starts making his next move by hijacking a subway train while Togane does something terrible to Aoi.

Kamui floods the subway in order to take 500 train passengers hostage, freely using the Dominators to try and spark an overload in the Sibyl System and access its bypass system. Meanwhile, Kasei orders Akane to assassinate Kamui by setting off a detonation that would kill all the hostages, using the news that Aoi has been found dead to drive her towards that goal. While hesitating over what she should do, Kogami appears in Akane's conscience, encouraging her to find another option that doesn't necessarily involve killing. Akane gets into contact with Kamui and then confronts Kasei, stating her desire to overcome her plans. While Kamui manages to stop the detonation and releases the hostages, Akane confronts Togane, having deduced his true nature and goal, before Kamui appears before them, preparing to fire his Dominator at Togane.

Akane subdues Togane before Kamui can shoot him, stating that even though she has lost many people close to her, she is still determined to protect the law. She leads Kamui to Sibyl, where they are confronted by Kasei. Asking Sibyl to reveal its true color, Kamui manages to expose Kasei/Misako Togane's Crime Coefficient and executes her. Akane leads Kamui to Sibyl's true form, where Sibyl acknowledges Kamui's existence and authorizes a collective Psycho-Pass, destroying some of its own brains to lower its own Crime Coefficient, before Akane arrests Kamui. Meanwhile, Shisui, pushed into a corner, attempts to set off the bombs but is stopped just in time by a long range paralyzer shot. Akane is instructed by Sybil to execute Kamui, and is once again confronted by Togane, who taunts her with Aoi's death to raise her Crime Coefficient. Kamui calms Akane down before sacrificing himself in order to shoot Togane. Togane flees, but dies from his injuries after being found by Mika, who couldn't bring herself to execute him and keeps the secret of her betrayal to herself.
