Saburo goes to the police's Headquarters, where he starts a discussion with Blue Oni, the occupant's leader.^[14] To release the hostages, Saburo has to decipher riddles and clues given by Blue Oni. As he investigates to solve the riddles, Saburo uncovers truths about medical doctor Daisuke Tosa and other hostages.^[15] Saburo continues retrieving the information, but is late in relaying his findings to Blue Oni, which makes him angry. Blue Oni urges Saburo to find out Governor Nagato's "sins". Saburo and Yūko's daughter, Emiri, has left the hotel where she was under police protection, and goes missing. Her whereabouts have also links to the case.^[16]

While he sleeps, Yuko frees herself and Emiri, and gets out, as policeman Ayabe arrives. Ayabe lets them in the car, as he searches for the mysterious man, who is awake and hiding. In Ayabe's incoming messages, one tells him to get rid of Yuko and Emiri. They try to escape, but are locked in. Yuko calls the police. Musashi is made aware.^[40]

Tendo, away from the group, reads a note from the Beasts. She could poison one of the hostages to be let free. Police learn that Ai Tamba was killed by Kawagoe under Kitami's orders, but before he confesses, Kawagoe dies poisoned, supposedly, by Izumi.

A first "Wildcat" is named: Tetsuo Mutsu, founder of Mutsu Construction, involved in the airport construction. A new "Wildcat" took his place after his death 10 years before. The hostages, headed by Kitami, capture Rumi Kakegawa (Ox), and demand Yuzuki to let them go. Niimi and his followers clash with Yuzuki. Izumi orders a team to go after Musashi, who has taken Tendo. Kitami, suspected to be the Wildcat, confirms it. However, Niimi finds information on a chip that counters it. Niimi blocks the Beast's channel with his own signal and demands Musashi to reveal what Yuko has done, threatening to kill her.^[66][48][67] Musashi learns that Yuko didn't attend Momoko Niimi, due to the hospital giving preference to someone else. As Musashi says this, Iwatsuki reveals herself as a beast. A small bomb goes off in police HQ. Musashi is now the next hostage: the headphone Musashi is wearing has a bomb. Police have to find the reason behind the disappearance of Kenichi Musashi. Something strange in the beasts' PC makes Yuzuki and Saki think there is a traitor within.^{[68][69][70][71]}

Kenichi Musashi's mental health was thought as his reason to stop working at City Hall. However investigation results were false. He was searching for evidence of Kitami's fraud, and was killed in front of Futaba, who was Kitami's secretary at the time. Futaba, who hid this from Saburo, also kept Junko Suruga, Kenichi's lover and the twin's pregnant mother, away from the family, supposedly to prevent her from getting involved. Junko, forced to raise the girls by herself, got involved in bad dealings, and left the girls alone. Yuzuki and the others tried to escape from the airport during the pre-recorded stream, while Niimi was on his way there. Sena betrays Niimi by going to Naoki Tamba, enraging Niimi. Five beasts are captured by the police. Saki is held by Niimi, who is pursued by Yuzuki.^{[72][73][74][75]}

Sena tells Musashi, Niimi's plans. Niimi went to the Yokohama Bayside Hotel, where the airport's Promotion Council general meeting was being held, planning to blow up himself, the other renegade beasts and the hostages, taking everyone with them. Shima, helped by Iwatsuki, blocks Niimi's broadcast. Yuzuki shoots Niimi. Musashi stops Futaba, who says she is the Wildcat, from killing herself. At the end of the episode, a free Yamato appears on a rooftop.^{[76][77][78][49]}

Saburo Musashi transferred to the Police's BCCT section. A hostage incident in a passenger bus. Though Musashi successfully saves the hostages, a bomb carried by the hijacker explodes, and he barely escapes. On another day, Musashi, Sakura Izumi, An Honjo and Yuji Ibuki, his brother-in-law, are at a TV station, where coverage of the elections take place. The candidates have received death threats. One wears an Ayakashi mask. Musashi goes searching for Ibuki, who is nowhere to be found, when a bomb goes off, trapping Musashi in the explosion. The masked team sends out jamming signals and overrides the system, effectively trapping everyone in the station, including Yuko Musashi, Saburo Musashi's wife, who supervises a medical drama, and their daughter Emiri, who finds and is protected by Musashi. Yuko, chased by members of the masked team, finds Izumi and remains by her side. Musashi and Izumi eventually meet and try to get Yuko and Emiri out through the air vent. Ibuki was taken to an abandoned building. In front of him, Koichi Yamato, with his oni mask, appears. Yamato asks Ibuki to kidnap someone, and Ibuki accepts. A police team arrives where Ibuki was held, but he is no longer there. However, there are two burned corpses. Musashi and the others are caught in the middle of a fight with the Ayakashi. Izumi steps between him and his attacker and gets hit by a bullet. Musashi holds a bleeding Izumi in his arms.^[97][98]

Musashi leaves Izumi with Yuko, and takes Emiri to an air duct, giving her a phone for the police. He returns to where Yuko is, but Tengu and Gashadokuro, who had followed him, are there. The Ayakashi take them and Izumi to the main studio with all the hostages, of whom they pick 13, letting the others go. Musashi, wearing the station's mascot suit, is let go, but with a "bomb" on his back. The bomb was a "joke", as a messsage coming out of it said. Yuko operates on Izumi, while the police find on one of the corpses a QR code that links them to the studio. Members of the News Fact team are forced to prepare to broadcast. Honjo, in charge at HQ, finds how to infiltrate the studio, unbeknownst that the premises were under CCTV surveillance. The first of the Ayakashi's victims, Ryutaro Mikawa, a soccer coach, candidate for governor, is held over a hot water bath, its temperature rising every minute. Musashi, in HQ, is to find his "darkness". Somewhere else, Ibuki drives Yamato to a dry cleaners. The person he is to kidnap is there, but Ibuki betrays Yamato by telling the man he is in danger. Yamato stuns the man, and warns Ibuki not to try that again. The police identify Fukue, the one who kidnapped Ibuki, and Musashi goes after him. Tengu and Gashadokuro take their masks off, after the first reads information on Yamato. They were who helped Yamato when he escaped. After demanding to know Ibuki's whereabouts, Musashi picks up a fox-stamped paper used for Kokkuri dropped by Fukue, then looks up as a rebar starts falling on them. ^[96][99]

Fukue was a staff member of the coaching team of which Mikawa was the head coach. Mikawa had physically abused Reo Tsukumi, a student under him. "Amabie", reveals to be his mother, a pharmacy attendant resentful because Mikawa was the cause of her son's death. When Shima investigates who she is, what he gathers includes a security camera's footage that shows a blurred image. Shima then adjusts the image, that shows Yamato. One of the "Ayakashi", Gashadokuro, has been stabbed, and others who were with her went to look for Yuko to save her. Somewhere else, Yamato kidnaps the cleaners' owner and his daughter. Musashi, having to solve the Ayakashi's clue, hidden in a box, is stung and poisoned by the mechanical insect inside it.^[93][100]

Musashi, life count at 90 minutes due to the poison, and in a room with a bomb on the door, continues investigating, while Honjo commands the team in HQ. Governor Oshiba is put under a tub with 70 kilos of content that he has to hold with a rope, or else it will fall and crush him. Yuko operates on Gashadokuro. Ibuki is targeted by Masaki and his daughter. Masaki tells him that Yamato is the "Noppera-bō" of the underworld. During the Ayakashi's broadcast, Kasa-obake uncovers himself. Oshiba had killed his wife, who tried to accuse him of collusion with a construction company. It was also learned that director Hinode was trying to hide Oshiba's crimes through manipulation of news information. The people in 2 related cases whose images were blurred were actually the same person, someone who Hinode knew from college. The Ayakashi who were seeking revenge this time were "Bakeneko" and "Kappa". Oshiba is in a room. Musashi, having been given the antidote, goes there and demands information. Oshiba tells him he doesn't know who is responsible, but that there is a puppeteer (kugutsushi [ja])^[101] controlling everything. Oshiba is on a chair that shocks him, and that has a bomb underneath.^{[102][94][90][91]}

Musashi has to investigate Hinode. Honjo orders Shima to investigate anyone who could have infiltrated the police when Yashiro says there is no suspect of Oshiba's electrocution. Meanwhile, the hostages talk among themselves about how Hannya has special considerations for Yuko. Kappa and Bakeneko are in charge of the next "case": Hinode is put in front of a "pie–throwing bazooka" that throws cream and nails. 312 cases of false information generated by Hinode in his 10 years on News Fact, one of them was the death of Kunimitsu Takatsu, a Teito Daily social affairs reporter, who died by jumping into a moving fire truck and being dragged by a spike tire. One week before his death, News Fact aired the news of a peeping Tom in a university's woman's dormitory that hadn't been caught. The suspect's image was Takatsu, and comments started flooding SNS. Musashi's investigation takes him to Sakate, an actor hired by Hinode. Hinode was revealed as the voyeur. Kappa and Bakeneko uncover themselves. They are Takatsu's children.^[95] Hinode also had a hidden video of Izumi, planning to use it if she had died. All the hostages, except Yuko, are taken to a sealed room. Somewhere else, Yamato and Ibuki are being held captive by the Noppera-bo (Ayame Masaki declares herself as it). They are rescued by someone wearing a Wanyudo mask. Yamato and Ibuki talk about the chip implanted in Ibuki, that it is not a bomb but a GPS, that is how they were found. Wanyudo finds some files in the Noppera-bo's computers. One of them is marked Kamaitachi. Yamato offered Ibuki the answers he needed, if he joined Yamato and the others. This was 3 months before the capture of the station. Hannya reveals, surprising Yuko and Musashi, as it was Yuko's brother.^{[103] [104][105]}

Musashi has 2 hours to find the reason why Ibuki became Hannya.^[106] The 6 hostages only have 5 masks against the gas that could be liberated in the room. Musashi thinks about what could be the reason, and concentrates on the Kamaitachi incident, occurred 5 years before.^[107] In a flashback, more of the relationship between Yamato, the Ayakashi and Ibuki is revealed. Not one trusted Ibuki, who was tested by Tengu with Russian roulette. Yamato told the group to use guns as a way to obtain results, without killing anyone. The day of the occupation, Ibuki faked being kidnapped to deceive the police. Musashi and Amakusa go to the Noppera-bo HQ and find the information on the Kamaitachi incident. Amakusa pulls a gun on Musashi after seeing an email sent by the Noppera-bo to the police. Almost missing the broadcast, Musashi links with Ibuki/Hannya to answer. Musashi tells the truth about Ibuki's girlfriend and Yashiro's involvement. Ibuki's girlfriend, Fuuka Kozu, was accused of killing news reporter Mitsuru Amuro. Yashiro asked Noppera-bo to cover up the case, and make Fuuka the culprit. Musashi's fault was having arrested Fuuka without any proof.^[108] Yashiro had also instructed Amakusa to arrest Musashi, since he was the culprit in the Kamaitachi case. Ibuki lets the gas fill the room to prove the falsehood of Shikine, who, after "sacrificing" himself for the others, fights for a mask. A new broadcast starts. Yamato is chained inside a freezer. Musashi is reminded of Emiri being chained inside a freezer truck.^[109]
