The story of Season 23 begins with Ukyo accepting instructions from his superiors to compile the 150-year history of the Metropolitan Police Department.

In the 7th year of Meiji, the Metropolitan Police Department was founded by the former Satsuma feudal lord, Kawaji Toriya.Together with the Secretary of the Interior, Toshimichi Okubo, he founded the police agency and became the first-generation police chief (currently the police chief).However, Okubo later suffered the tragedy of assassination——.Like that incident in the dawn of the police, there was an incident where a big shot politician was killed!What stands in the way of the Tomei-kei who begin the investigation is the reality of the widening gap between rich and poor in modern Japan, as well as the ambitions and conspiracies of powerful people spreading in the political world -!?

150 years ago and now——As society changes, has “Justice” also changed...!?​

When Ukyo (Yutaka Mizutani) was appointed to summarize the 150-year history of the Metropolitan Police Department, House of Representatives member Ashiya (Shiro Namiki) was killed.Ukyo and Kaoru (Terawaki Yasufumi), who rushed to the scene quickly, watched the search operation of the first section.

On the other hand, this incident also caused a chain reaction in the political arena.For Tonegawa (Ogata Yoshihiro), known as the “Shadow Prime Minister”, this is the perfect opportunity to abandon Prime Minister Fujiwara (Shiba Toshio) whose support rate is low.When the head of the internal affairs investigation department, Kamiko Kamiko (Yukie Nakama), got the news, Fujiwara was forced into a corner and could not hide his shock.

Ukyo and Kaoru met unexpected characters while pursuing clues at the scene.He is the young man Takada Hajime (Kato Kiyoshiro) who once met Ukyo through other incidents and received Ukyo's help to move towards a new life. Takada Hajime is currently working as a police officer in the local affairs department. He noticed a suspicious person nearby and began to follow him.investigation.

After receiving the clues provided by Takada, Ukyo and Kaoru split up and continued to track the incident.During this investigation, Takada had a good relationship with his senior Nishina (Kenta Uchino), who was also on the same duty, and gradually showed the style of a police officer.However, events began to develop strangely afterwards.About 150 years ago, Minister of the Interior Okubo Toshimichi was assassinated. The historical cases of that year and the current emergency situation are actually highly restored...!

Behind the murder of the congressman is the ambition and conspiracy of the powerful!?

Prime Minister Fujiwara (Toshio Chai) was attacked by a remotely controlled bomb.This unpredictable event is closely linked to the previous killings of congressmen, and people can't help but think of the historic events of 150 years ago, when Okubo Toshimichi and Ito Hirobumi were assassinated one after another.

However, the police could not even determine the real target of the murderer.On the other hand, Ukyo (Yutaka Mizutani) who rushed to the scene noticed from the traces on the scene that the terrorist operation may have used black market labor.His reasoning is accurate, and as the clues are followed, it gradually becomes clear that there is a character deeply involved behind the series of events.The police advanced the investigation along this clue, but Ukyo felt a little violated.

At the same time, Ukyo and Kaoru (Terawaki Yasufumi) visited the police station where Takada (Kato Kiyoshiro) worked. Takada asked them to accompany them to the crime scene. He hoped to learn Ukyo's investigative techniques personally.They re-verified the scene and discovered unexpected facts from the remaining blood stains.However, just after that, Kaoru and Takada, who were investigating separately, fell into a desperate situation.In addition, there are also unusual trends surrounding Tonegawa (Ogata Yoshihiro), who secretly controls the political world...

This incident will become a major case etched in the 150-year history of the Metropolitan Police Department.

What will be the fate of Kaoru and Takada who fall into a cunning trap?

Ukyo (Yutaka Mizutani) is in a mountain villa where mobile phone signals cannot be covered.The guests who stayed at the hotel included the novelist Kishi (Eri Busse) and his accompanying editor. Counting Ukyo, there were about seven people in total.Judging from the way they spend their days, they seem to be a bunch of weirdos.On the other hand, the hotel owner Kashimura (Fukushi Seiji) appears to be honest and reliable, quietly busy with his work.However, there was a hint of gloom in his expression...

At the same time, Kaoru (Yasufumi Terawaki), who was enjoying a vacation at a hot spring hotel, witnessed a worrying video at the urging of Miwako (Suba Suzuki).The video seemed to accidentally capture a man falling from a building, along with a man who looked like Ukyo.

The next morning, Kaoru gave up the rest of her vacation and returned to work early.He learned that in his absence, Ukyo had assisted in the search operation for D products.When Kaoru visited the house of a suspicious person who emerged during the investigation, he found that the man had died mysteriously.

During this period, ominous events continued to occur in the mountain villa where Ukyo was staying!?

What is the real purpose of Ukyo who is stranded in a mountain hotel?

Xun will follow his footsteps and gradually approach the truth behind the incident.

When the clues are gradually connected, the unexpected truth gradually emerges!

Two bodies were found in the ruined building.One of them, an elderly man entrusted with the care of the building, died from what appeared to be heart failure.The other is a middle-aged man named Ghana (Mamuya Yamaguchi), who has multiple criminal records and the cause of death was strangulation.The police began to investigate whether it was internal strife or murder.However, the situation at the scene was abnormal. For some reason, there were glowing mushrooms growing on Yamaguchi Mamuya's back and the surrounding floor.

Ukyo (Yutaka Mizutani), who was very interested in this scene, and Kaoru (Yasufumi Terawaki) took action together, but the problem was that not only was that mushroom not recorded on the Internet, it was also not recorded in illustrated books, and it was an extremely rare species.In order to search for clues, the two began to visit experts in mushroom research and professional scientists in environmental protection.After listening to what they said, I realized that that kind of mushroom can bring huge economic benefits and is a dream species that has attracted world attention.As the investigation progressed, it was discovered that environmental groups had been formed in Ghana.According to what Aiba (Nakao Masaki) at the telephone exchange said, Ghana seems to have two faces, the outside and the inside!?

There are two faces looming behind the seemingly dead man.

Ukyo (Yutaka Mizutani) went to a mountain hotel on vacation, where a guest room staff was killed.What is puzzling is that the deceased was holding a rare butterfly found only in Southeast Asia.Ukyo heard that some residents claimed to have seen “human soul”, so he started investigating with great interest.It is said that this hotel is a well-known psychic location, and there are even curious people who come specifically to see ghosts.

Kaoru (Terawaki Yasufumi) meets a girl who is sketching butterflies in the museum, and they search for butterflies together.However, the girl, who was convalescing, was reportedly unwell and her mother protected her.The father also appeared at the scene, but the couple seemed to be separating and their relationship seemed very unharmonious.Further investigation revealed that the murder scene was actually the room where the father had just checked out.On the other hand, according to witnesses, the curator (Toshiya Toyama), although assisting in the investigation, seems to be troubled recently...!?

While investigating, Ukyo becomes obsessed with searching for human souls.

There is an unexpected connection between the murders and the ghostly disturbance...!?

San Hiroko (played by Atsushi Fukasawa), a gay bar mom with close ties to the Tomei clan, was witnessed near the scene of the murder and then disappeared.The person who was killed was Koda, the president of a consulting company suspected of using NPO to launder money.Using the volunteer canteen where Hiroko worked as a cover, tax evasion and embezzlement of aid were discovered.Hiroko went to protest, but seemed to just disappear.

Ukyo (played by Yutaka Mizutani) and Kaoru (played by Yasufumi Terawaki) teamed up with Hiroko's volunteer partner Izumikawa (played by Shun Nishimei) and others to start the search.On the other hand, the Investigation Section 1 heard what happened from the judicial scrivener Yano (Reiya Takaraki).Yano suspected that Koda had a way to evade taxes, and it was Yano who finally contacted him.At the same time, the possibility of Koda's connection to the unsolved robbery 10 years ago surfaced.

Ukyo and Kaoru chase Hiroko who suddenly disappears

A robbery before the statute of limitations and a wonderful coincidence...!?

The unreasonable modern society is illuminated by the special life system! 

An assassinated body is found in Hachioji's park.The victim is Obi Mi, who was wanted on suspicion of killing his former partner 29 years ago and has been on the run.The case has expired, and the Search Section believes that people related to the case 29 years ago are involved, so they start an investigation.At the same time, Ukyo (played by Yutaka Mizutani) received a contact on his mobile phone from Miura (played by Ryosuke Ohtani) who was originally from the First Investigation Division.

In addition, the reunion with Kaoru (Terawaki Yasufumi) was fleeting, and an unexpected request was made.Miura was responsible for dealing with the survivors in the case 29 years ago. The victim's fiancé Tsunekawa (played by Kamio Yu) found Oshimi on his own and committed the crime 29 years later. Miura felt heartbroken about this.After understanding Miura's urgent mood, Ukyo and Kaoru took action. In order to find clues, they went to the supermarket in charge of Tsunekawa to inquire.So a few days ago, Oshimi showed up at the store and had an argument with a part-time woman.Ukyo and Kaoru heard about the situation directly from the woman, but it seemed like she had a reason herself...!?

Does Miura think the former detective’s intuition is correct…

The complex intertwining events of 29 years ago and now

A shocking truth lies ahead of this sad revenge drama!

Kaoru (Yasufumi Terawaki), who serves as a runner for a visually impaired woman Auri (Maria Mori), was stabbed while running.It was thought that the crime was committed by someone who had a grudge against Kaoru, but there were no clues at all.At this time, a man named Noze who worked in the same flower shop as Lan Li arrived.Noze seems to often serve as Ami's companion, and seems to be closer than a mere colleague.Ukyo (played by Yutaka Mizutani), who started investigating, learned how Amari lost his vision.Two years ago, Lan Li accidentally appeared at the scene of a robbery and murder, and fell down the stairs while struggling with the prisoner.He is said to have gone blind.The incident has not yet been resolved, and Ukyo suspects that Kaoru's stabbing incident is related to this incident.Lan Li has undergone surgery and is very likely to regain his vision in the near future, which also makes this reasoning credible.Further investigation revealed that the robbery and murder two years ago were related to the huge corruption case in the district government.

What is the true face of the visually impaired female witness%?

There is a shocking darkness hidden in the unsolved incident 2 years ago...

Ukyo's reasoning will illuminate the hidden truth!

At this time, Ukyo met the mother who was separated from the 4-year-old girl and began to help Jinchuan find the lost child.On the other hand, on the TV station, the popular news anchor Hiyama (played by Masanobu Takashima), surrounded by his assistant Takebe (played by Mitsuomi Takahashi) and the TV station's senior executives, is preparing for a year-end special program.However, the situation changed when Hiyama received a threatening letter from someone claiming to be a joker, saying that he would leave his daughter to you.The girl Ukyo is looking for is Hiyama's daughter.The prisoner's request is to conduct a live broadcast as scheduled, and his intention is unknown.

At this time, Miyako (played by Yukie Nakama) and Mineaki (played by Koji Ishizaka) are invited to participate in the year-end party of the ruling party's big shot Congressman Ijichi (played by Kenjiro Ishimaru).Itachi seems to be troubled by the recent spate of incidents in which groups related to anti-social organizations calling themselves “joker” have inflicted violence on their opponents.On the other hand, Ukyo believes that the purpose of the kidnapping is to target Hiyama, who criticized Joker on the show, and has contact with Joker-related men secured by Tsunoda and others.The man denied participating in the abduction, but testified that the TV station had an accomplice“...!?

On New Year's Eve, the special life system ushered in the ”last day%!

Ukyo (played by Yutaka Mizutani) who came to the art museum was taking shelter from a sudden storm when a young man who was waiting with someone appeared next to him.Ukyo was impressed by the young man's unique umbrella.The next day, the bar owner's wife was beaten to death.There were traces at the scene that the young man's umbrella was placed there and taken away at the time of the murder.Ukyo noticed that, and searched for the young man's whereabouts with Kaoru (Terawaki Yasufumi).

After investigation, it was revealed that the young man was the only son of an umbrella shop that had been operating for many years, named Fukumaru Kengo (played by Usui Masahiro).However, Kengo had a conflict with his craftsman-like father half a year ago and now seems to have run away from home.Afterwards, Ukyo found Fukumaru and pretended to have a chance encounter.After hearing the whole story, Fukumaru took shelter from the rain as an opportunity to communicate with the woman he had an unrequited love for, and they often met for trysts.

However, the woman named Tazi (played by Qingdao Xin) suddenly disappeared six months ago.Ukyo reasoned that the umbrella that disappeared from the scene might be a gift from Fukumaru to Toko, so he began to investigate whether there was any intersection between Toko and the victim...!?

Itami (played by Kazuhisa Kawahara), who broke into the special life system, told Ukyo (played by Yutaka Mizutani) something shocking.“Kaoru Kameyama was killed...”.The two people who went to the scene learned a shocking fact there.Kaoru Kameyama, who was killed and abandoned in the river, was an employee of a trading company, and he and Kaoru (played by Terawaki Yasufumi) of the special life department were different people with the same name and surname.In fact, Ukyo knew that Kaoru attended a party that day.

That is the “Kameyama Kaoru Association” where men and women with the same name and surname gather to promote harmony.It is said that Kameyama of the trading company who was killed was the representative of the association, and Kaoru of the special profession became the commander-in-chief for “some reason”.At this first gathering, in addition to Kaoru Kameyama (Akini Hano), a woman who works in a government agency in Tottori and is known as “Government Agency, there were a total of 33 Kameyamas with various experiences.Kaoru.As the search progressed, the venue turned into a sort of secret room during the party.Since there was no trace of the victim, the murderer abandoned the body from the escape ladder after committing the crime.Therefore, the suspects, excluding the victim, were narrowed down to 32” Kaoru Kameyama“.
