Plot
A general hospital in Kanagawa Prefecture, Kaiseido Hospital, is suddenly taken hostage by an armed group, called "Hyakki Yagyo", who protect their identities wearing oni masks. Yūko Musashi is a heart surgeon at the hospital. She is inside it during the hostage crisis. She is currently separated from her husband, police detective Saburo Musashi, with whom she has a daughter. Saburo Musashi is currently on leave and receiving psychological treatment at the hospital for a fatal incident in which he was involved the year before. Among the people there, there is also the Governor of the prefecture, Michie Nagato, and Yui Inaba, a former reporter, currently a video streamer in search for current affairs. Saburo has just ended his treatment, and is calling his wife, to no avail, when he hears a faint tick tock behind a closed door. As he opens it, a bomb goes off and the explosion throws him clear over to the other side of the hall. He recovers from the explosion, and reports the incident to police superintendent Izumi, when he is surrounded by a group of the mask-wearing captors, who attack him with gun-wielding drones. He manages to escape the drones, and reports the hostage situation, when he notices that his wife is there, among the taken. While this is happening, in another place, the armed group's leader starts streaming in their newly opened YouTube-like channel, which immediately starts gaining viewers. Saburo goes to the police's Field Command Headquarters, from where he starts a discussion with Blue Oni, the armed group's leader.

Saburo has to decipher riddles and clues given by Blue Oni, in order to continue with the hostage's release, only to uncover some dirty details of those people linked to those riddles and clues. As Saburo is on a time-limited search for things that will uncover truths about medical doctor Daisuke Tosa and others, his wife is trying to negotiate the release of nurse Shiori, who is ill, and other hostages. Saburo continues his mission of retrieving the information, but is late in relaying his findings to Blue Oni, which makes him angry. Saburo is in shock as Blue Oni reveals who he has been pointing a gun at this time: Yūko. Blue Oni urges Saburo to find out Governor Nagato's "sins", at the same time that it is shown that the Musashis' daughter, Emiri, has left the hotel where she was being protected by the police, and goes missing. As the story develops, so do the stories of the masked team, including Kiyoshi Hitachi (Gray Oni), a psychiatrist, and his daughter, Arisa (Peach Oni), and Minoru Sado, the hospital's Head of Surgery, who gets shot by the police's SIS sniper team, as he takes the place of Blue Oni at the entrance of the hospital, where Saburo has gone to negotiate. The story continues with Blue Oni showing images of an unconscious Emiri, who was taken by one of the members of the masked group, and has been locked in a freezer. With less than an hour's time, Saburo has to solve the riddle Blue Oni gives him and save his daughter. Reporter Yui Inaba, who has been behind the scenes relaying information about the hostage situation on her channel, has the biggest scoop, as she reveals the identity of a pair of the masked team on a live feed.

Plot
The series starts with a scarred woman running away from someone wielding some sort of knife. She steps on a paper with a zodiac seal as she runs from the man. Musashi, who has been working normally as a detective, arrives on time to stop him. Musashi locks the man in the car, and goes back to see if the woman is OK. She whispers, so he closes in to listen, and she sticks a needle on Musashi's neck, rendering him unconscious. Musashi's wife is at the hospital, taking care of a new patient. In an airport, an electronic sign reads "Kanagawa New Airport". Although the airport is functioning, there is still to be an opening ceremony for it, for which the administrator is getting ready with her team. There is a lot of activity inside the airport. A suspicious group of airline attendants is going around it placing suitcases with some sort of device at the entrances, while a cleaning crew stops around a corner, out of the view of the surveillance cameras, and take out guns of the garbage bins they carry, shooting some sort of tranquilizing darts to security police. Musashi is having some sort of a dream listening to a familiar voice. In reality, someone is trying to wake him up: his sister, who has been tied up next to him, in a truck. The pair talk about how they got caught. Futaba tells Musashi that it was responding a call regarding the disappearance of their older brother Kenichi, occurred 30 years before. In a sort of warehouse, there is a pair of beast-masked people. One has a tablet and has logged in somewhere. Words across the screen read "60 minutes until airport occupation". At around 15 minutes to the airport occupation, a woman with a mask gasses the police in the airport's security post. The cleaning crew then appears to leave their uniforms and put on different clothes and hide their faces behind masks as well. They enter the security room, where the surveillance screens are, using a card from one of the downed security policemen. The one with the tablet at the warehouse then hacks the airport's system, as the airport's opening ceremony is taking place. The armed masked people now enter the check-in hall. The Musashi siblings have just arrived somewhere. and are "greeted" by a pair of masked people, which makes Musashi remember the past occupation. They are at the Kanagawa New Airport, which is now being overtaken by the masked group. As the one with the tablet is locking all the doors and latching all the windows, the Musashi's try to find a way out, only to be caught in an explosion of one of the suitcases.

News of the airport reached the police, which has now sent teams out. Musashi, from inside it, calls for Sakura Izumi, who has been on leave since the capture of the masked team at the hospital. Although Musashi has tried to hide from the masked team, they have been keeping surveillance on him all the time, knowing his whereabouts at all moment. Izumi takes over the investigation, with the help of the local police and a new member of the team, taking the place of Suruga, who has left. As the team receives information from Musashi, Shima and Iwatsuki notice that the animals from the armed group's masks follow those of the zodiac, but is missing two: mouse and dog. The police chase the two suspects, the ones who held the Musashi siblings, while the Musashis are being followed and attacked by a pair of the Beasts, and eventually taken with the rest of the hostages. The Beast's leader tells them they have become bait for the beasts. Soon after, the two suspects arrive at the cargo hold, unaware of the police, and communicate with the Beast leader. A surveillance camera live feed of them is then projected unto the main hall at the airport, and the HQ police team take notice of this. Izumi tries to stop the police team at the scene from moving on, but is overrun by Chief Kawagoe. The suspects open one of the cargo containers as the police close in. The container holds one of the suitcase bombs, exploding while HQ and all in the airport hall watch. The suspects are killed, fact that makes Musashi question the Beast leader their action. A group of hostages, including Futaba, are taken into a room.

Yuko is about to leave the hospital, when she receives a call from Emiri. As they are talking, a bloodied hand hits the window of Yuko's car. She gets out to see who and if they need help. It's a man, barely holding on, but who manages to slip some kind of device into Yuko's trouser pocket undetected. She gets closer to see his wounds, he demands Yuko to get into the car and drive at gun point.

Musashi is taken to another place, where he faces a familiar face, after the Beast behind it gets rid of the mask: Suruga. The Beasts have started a streaming (YouTube-like) channel and show the hostages in it. Musashi becomes the negotiator between the Beasts and the police, after being threatened by Suruga that if not, the hostages would die. The hostages, guided by Futaba, plan how to escape. The police are planning a way to close in on the group and arrive at the airport, checking through a trash chute, from which Musashi comes out, wrapped, and with a bomb on him, that he barely escapes from. As Musashi and the police investigate Suruga, a virus attacks KSBC's computers, rendering an image of Musashi and Izumi as dolls being eaten by the Beasts, before posting the clue to decipher. Just 1 hour to find Iwao Shirakawa's crime, with the help of Musashi and clue "given" by the Beasts, by holding Shirakawa in a locked fish tank.

Somewhere else, Yuko, still a hostage, is forced to go to her own house, where Emiri is, to cure the man.

Musashi learns that, a year before, Shirakawa sued Momoka Niimi for embezzlement after she complained about cases of power harassment from him. The abuse turned into online harassment. After her suicide, her PC was hacked, being the origin of the hack the Yonezawa Law office, the airport's lawyer's firm. When her friend Sena learned the truth about her death, she pledged to avenge her friend, so she became a Beast, the Rooster. Musashi arrives just in time to answer this to the Beast leader. A new broadcast from the Beast Channel shows different videos showing Shirakawa abusing his employees. The clock starts ticking again, and the team start a new investigation with the information provided by Sena, which takes Musashi and Honjo to an abandoned factory / warehouse, that is rigged with traps. Honjo ends up with her leg tied to a roller crusher, fighting for her life, while Musashi is trapped inside a type of jail cell, with the key to it inside him, in the form of a microchip that he has to cut out. A live feed is shared to the cell and KSBC HQ.

Musashi manages to escape in time to free Honjo, and learns that the microchip was a GPS. The escaped hostages get stuck trying to get out, but the doors need a number password. The other 3, still at the room, face the Beasts, who go for the next "victim": Yonezawa. Yonezawa is asked to reveal who he has ties with, but he was threatened not to reveal the person's identity, or else, his mother would die. So Beasts put him in a threadmill surrounded by electrified wire. Musashi has only 50 minutes to solve this time's problem. At home, Yuko tends to her kidnapper, who has Emiri at gun point. Something catches his eye from the photos in the Musashi's home.

The KSBC continues to help out, finding information to relay to Musashi. They find out that hostage Masao Mibu is really Shigeru Kitami, a member of the House of Representatives on the run. Kitami was accused of multiple crimes related to the hospital occupation incident the year before.

Futaba is called to the Beast's control room. She expected to be the next one, but Dragon thanks her for the information. When she realizes he's the one who called her about her brother Kenichi, she asks for information about him. Dragon says she will know once all the lies related to the airport are revealed. She and the re-captured hostages are then returned to the closed room. Musashi arrives just in time for the Beasts' stream, where they free Yonezawa and bring Mibu in. This time, "Tiger" and "Monkey" are revealed, much to the surprise of the entire investigation group, since it was former Special Forces SAT Administrator Kazuki Tamba and his son, Naoki. Both left the force 6 months before.. It was thought that Tamba's wife Ai, a freelance journalist, had died by suicide, after being slandered by allegations of fabrication, consequence of an article she had written, but there was no proof. It was about the content in it, which involved Kitami. At HQ, as Iwatsuki investigates Ai Tamba's files, she discovers a file folder that supposedly has no data, so Shima proposes going to data center to see its content, or find more information about it.

Musashi has again less than an hour to discover Mibu's (Kitami's) lies. That information may come from an unexpected source: Koichi Yamato (Blue Oni, leader in the hospital incident), who Musashi visits in jail. Musashi thinks Yamato and Suruga are linked in the current incident, but he says that they were only business partners in the past, relaying information. Frustrated, Musashi leaves, with one last phrase from Yamato: "Who were the animals not included in the zodiac?"

Yuko frees herself and Emiri and gets out the house, as policeman Ayabe arrives calling for her. He lets them in the car, as he runs into the house searching for the mysterious man, who has woken up and is now hiding. Ayabe left his phone in the car, and Yuko reads incoming messages, one telling him to get rid of her and Emiri. They try to escape, but are locked in. Yuko called the police, and the call is passed on to HQ. Ayabe returns and deciphers, by their scared faces, that they read the messages. They are now his victims. Musashi is made aware of this.

Tendo distances herself from the group, and reads a note passed by the Beasts, in which they give her the option to poison one of the hostages to be let free.

Shima discovers videos of surveillance cameras in the file.
