Story
A woman flees from an attacker. A paper with a zodiac seal. She pricks Musashi with a needle and renders him unconscious, after he rescues her from the attacker. Some airline attendants place suitcases at an airport's entrances, while a "cleaning crew" shoots tranquilizing darts at security police. Musashi and his sister talk about how they got caught. She tells him that it was related to the disappearance of their older brother Kenichi 30 years before. One of beast-masked people's tablet reads "60 minutes until airport occupation". 45 minutes later, it starts, with the airport's system hacked, as the opening ceremony begins. The beasts remind Saburo of the past occupation. The Kanagawa New Airport is now overtaken. The Musashis try to get out as one of the suitcases explodes.
Sakura Izumi, on leave since the last occupation, is requested by Musashi. Izumi heads the investigation, and a new member takes Suruga's place. As Musashi's information reaches the team, Shima and Iwatsuki notice the masks are animals of the zodiac, with two missing: mouse and dog. The police chase the suspects that held the Musashi siblings, who are attacked and taken with the other hostages. A live feed of the suspects, as they are killed by a suitcase bomb in a cargo container, is projected unto the airport's main hall. Izumi tried to stop the team at the scene, but is overrun by Chief Kawagoe.
The Beasts (YouTube-like) channel show the hostages. Suruga surprises Musashi revealing she is one of the Beasts. After the hostages lives are threatened, Musashi negotiates between the Beasts and the police. Futaba leads an escape plan. The police close in as Musashi comes out a trash chute with a bomb on him. One hour to decipher Iwao Shirakawa's crime's clue posted on the virus-hacked KSBC computers. A year before, Shirakawa sued Momoka Niimi for embezzlement after she complained about cases of power harassment. She died by suicide after suffering from off and online harassment. Niimi's PC, hacked by Yonezawa Law office, the airport's lawyer's firm, was used to change her testimony. Her friend Sena pledged to avenge her becoming a Beast, the Rooster. The Beast Channel showed Shirakawa abusing his employees.
Sena's information now takes Musashi and Honjo to a trap-filled abandoned factory. Honjo fights for her life over a roller crusher, while Musashi is trapped in a cell. The escaped hostages get caught. The next "victim", Yonezawa, has to reveal his ties without saying who it is. The police have 50 minutes. The KSBC relays to Musashi. Masao Mibu is in reality Shigeru Kitami, a House of Representatives member on the run from multiple crimes related to the prior occupation. Futaba goes to the Beast's control room, expecting to be next, but Dragon, who called her about Kenichi, thanks her for the information. She and the re-captured hostages return to the closed room. The Beasts free Yonezawa and bring Mibu in. "Tiger" and "Monkey" are revealed, surprising the police. It was former Special Forces SAT Administrator Kazuki Tamba and his son, Naoki. Both left the force 6 months before. Tamba's wife, Ai, a freelance journalist, died by suicide after being slandered by allegations of fabrication in an article involving Kitami, with no proof. Shima goes to a data center to find the content on one of Ai Tamba's files that Iwatsuki finds. Musashi has to discover Mibu's (Kitami's) lies, learning things from an unexpected source: Koichi Yamato (Blue Oni, hospital incident leader), who Musashi visits in jail. Musashi thinks Yamato and Suruga are linked in the current incident, but he says they only worked together in the past. As Musashi leaves frustrated, Yamato tells him: "Who were the animals not included in the zodiac?" Shima, who discovers surveillance cameras videos in the file, is trapped in the data center, and is found unconscious by Musashi and the center's security guard.

Story
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.
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 message 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.
