Don't Call It Mystery - Season 1

University student Totonou Kuno (Masaki Suda) has been making curry in his apartment since the morning. The landlord of the apartment appears there with the detectives of the Ohtonari police station, Kenichi Endo and Yuto Ikemoto (Matsuya Onoe). When asked about his actions at 10 o'clock last night, Sei answered that he was making curry by himself. Then, Yabu informed that the body of Sagae Ken (Fujieda Yoshiteru) was found in a nearby park, and asked the police station to accompany him voluntarily.
Sei is heard by Yabu and Nariaki Aoto (Michitaka Tsutsui). Sagae, who was killed in the park, was from the same high school as Sei and attended the same university. In addition, some witnesses have seen Sagae fighting for arranging at the time of its murder. Therefore, Sei was a suspect. However, Sei is innocent in pursuit of the bushes. He argues that the sighting information is clearly his own.At night, Sei was released on the condition that he would be interrogated tomorrow. Sei, who went to have the mobile phone returned to the detective Seiko Furo (Sari Ito), finds out that she is a pet loss. I also heard that Ikemoto would soon become a father.The next day, when Sei goes to the police station, Furo Hikari and Ikemoto, who were ordered to take fingerprints from the bush, are in the interrogation room. Sei healed the pet loss of the bath light with words, and advised Ikemoto on how to work for his wife who is about to give birth. Yabu tells Aoto that such an arrangement must be the culprit.
On the third day of the interrogation, Sei gave hope to Furo Hikari, who was worried about his standing position in the station. Yabu comes there and tells him that the fruit knife that killed Sagae was found and that the fingerprint of Sei was detected.

The route bus on which Totonou Kuno (Masaki Suda) got on to go to the museum was jacked. To the criminal who asks the passenger for his name, Sei asks the purpose and name of the bus jack. Then the criminal calls himself Inudo Otoya (Ryohei Abe), but he didn't tell him that he would understand the purpose.At that time, the investigation headquarters for serial murders stood at the Ohtonari police station. A new fourth body was discovered in the morning. The victims have nothing in common, and the suspect's eyes aren't even visible. While Nariaki Aoto (Michitaka Tsutsui) and Yuto Ikemoto (Matsuya Onoe) are busy, Seiko Furo (Sari Ito) is not allowed to participate in the investigation. At that time, Furo Hikaru was informed that her junior police officer had reported a bus jack. However, there are no problems with local buses and sightseeing buses. Bath light talks to Aoto and others, but she is dismissed as she is just a prank.The bus with the train stops at the park, and Otoya sends the passengers to the bathroom one by one. The first person to go to the bathroom thinks about how to contact the outside. Sei, who had been informed of the contact information by Ikemoto before leaving, wrote down the current situation on a memo paper and placed it in a place where the criminal could not find it.
When the bus starts running again, Sei makes Otoya angry. Otoya who went upside down was cut with a knife, but passenger Sho Kumada (Eita Nagayama) protected it. In addition, passenger Masao Sakamoto (Yuki Kubota) beats Otoya. The passengers are relieved, but Sakamoto points the fallen knife at the passengers ... After that, the bus arrives at a mansion at the direction of the criminal.

Seiko Furo (Sairi Ito), Shigeaki Aoto (Michitaka Tsutsui), Yuto Ikemoto (Matsuya Onoe) and others were the first to notice the Inudo residence where Totonou Kuno (Masaki Suda) and others were confined. The criminal is in a hurry. At that time, passengers urged by the criminal to confess 'the heaviest sin I have ever committed' in the residence. Next to Rila Rouki (Hiccorohee), Megumi Kashiwa (Aimi Satsukawa), and Ippei Awaji (Yuki Morinaga), Yukihito Narasaki (Akio Kaneda) spoke. Narasaki, who committed suicide by his subordinates, is worried because his bereaved family has blamed him for himself. Sei who heard the story heals the heart of Narasaki with words like Lira and others.

When Totonou Kuno (Masaki Suda) is enjoying making curry, he receives a call from Seiko Furo (Sari Ito) on his smartphone. She responded with an unpleasant premonition, and Yumitsu wants her to help solve the mystery of the incident. It is the identification of the bomb threat location posted on the dark site. The ciphertext of the alphabet is added to the notice, but police officers cannot clarify it. It was posted yesterday that it was set up in Shinagawa, but fortunately the building written in the notice was identified, so the bomb was discovered and the attempt ended. However, there was a notice again, and this time it was set up in the jurisdiction of the Ohtonari station, so Yuto Ikemoto (Matsuya Onoe) turned to Furo Hikari to ask for cooperation.At the reception of the bath light, I went to the interrogation room again. This is because the cooperation of investigations with civilians cannot be known to Nariaki Aoto (Michitaka Tsutsui) and others. Sei solves the mystery of yesterday's ciphertext. At that time, there is news that the second bomb was found. Sei is praised by Furo Hikari for his ability to break the code, but something gets caught. Meanwhile, the suspect was identified from the address posted on the dark site, and the suspect was interrogated but denied the crime. Ikemoto and Furo Hikaru are convinced that the suspect is almost black, but Aoto suspects that he is not wet because the address can be easily identified.The next day, the third notice was posted as Aoto was concerned. Sei who doesn't know such a thing goes out to eat in the rain. Then he was approached by a stranger (Tasuku Emoto). After having a conversation for a while, Sei finds out that the man has lost his memory.

Totonou Kuno (Masaki Suda) hit his head in the bomb demon incident. He wasn't traumatized and had nothing to do with it, but he was admitted to the Onei General Hospital for inspection just in case. Yuto Ikemoto (Matsuya Onoe), who knew the situation, advised Nariaki Aoto (Michitaka Tsutsui) that he could have the hospitalization fee because he cooperated with the police. If Aoto permits, Seiko Furo (Sari Ito) goes to the hospital for the procedure.When Sei, who had shopped at the shop, returned to the hospital room, he received a small baggage with his address and the client's name. When she opens a box she doesn't remember, she finds dried flowers and a letter inside. From the text of the letter, I noticed that the arrangement was from Inudogaji (Eita Nagayama), and when I changed the box while being wary that there was something wrong with it, something fell. When Sei was looking for it, the bath light came. Bath light was upset by the ring that Sei picked up, and handed over her procedure form and returned immediately.That night, when Sei was about to go to bed, an old man in the next bed called out. The old man calls himself Goro Ushida (Fumiyo Kohinata) and says he is a retired detective. Then, Ushida talked about the case he was in charge of with his partner detective, Shinji Shiratori (Kazuyuki Aijima). Ushida does not talk about the resolution of the case, but solves the mystery as a problem. Reluctantly, Sei answered the second question perfectly.
The third question is about an unsolved case in which women who prostituted 22 years ago were killed one after another. At that time, the suspect was identified as Gento Hagoku, but he was not arrested. At that time, a woman who was being targeted by a feather eater contacted the police to ask for her protection. Ushida heads to the place designated by Shiratori and the woman ...

Totonou Kuno (Masaki Suda), who is admitted to the Onei General Hospital for inspection, goes to the greenhouse in the hospital on the night before discharge, guided by the code hidden in the hospital bulletin board. There, Sei met Leica (Mugi Kadowaki), who conveys words with numbers that combine pages and lines of 'Self-reflection'. Leica, in numbers, disappears by instructing him to come back to the greenhouse at 3 pm the next day.
The next day, after completing the discharge procedure, he went to the hospital restaurant to have lunch until the time specified by Leica. Then, he collides with the patient Ryuta Shimodo (Amane Okayama). I apologize for the adjustment, but Ryuta has a difficult habit and does not forgive. However, Ryuta was frustrated and left when he calmly returned it.At 3 o'clock, when Sei went to the greenhouse, numbers were written on his floor. When I checked it in 'Self-reflection record', it was in the soil of a certain place. When Sei digs there, a plastic bag containing something comes out. At that time, the scream of a woman who stands still. She is Manami Umezu (Atsuko Anami) who manages the greenhouse. The plastic bag was filled by Manami for some reason. After hearing from Manami, Sei solves her worries. Sei, who broke up with Manami, found an envelope pinned to the trunk of the cherry blossoms. When the Leica number to look inside was opened, there was a picture of a wall with graffiti on it. The graffiti looks like a flame-like mark. The address was written on the back of the photo.When Sei went to the address written in the photo, the house seemed to have burned down. Sei found Rikuta among firefighters, police officers, and rubberneckers. Rikuta, who knew that he was being seen in a regular manner, disappeared with Kaonto Ihara (Taichi Saotome) who was talking. Then, before I knew it, there was Leica next to Sei ...

Guided by Leica (Mugi Kadowaki), Totonou Kuno (Masaki Suda) began investigating a strange arson murder case. Then, in the family of the dwelling that was set on fire, the parents died and only the children were saved. In addition, from information such as Seiko Bath Mitsu (Sari Ito) and other police, Sei confirmed that there is an urban legend site about 'Angel of Fire' in which an abused child asks for the killing of his parents. And Sei learned that Ryota Shimodo (Amane Okayama) also lost his parents in a fire caused by arson. However, on Christmas Eve night, Rikuta called him to help with the event held at the Onei General Hospital, and he was attacked by the warehouse. The warehouse also detained the parents of a child who was hospitalized and suspected of being abused.Two days before that. Naruaki Aoto (Michitaka Tsutsui) and others investigating the arson murder case could not be arrested due to insufficient evidence in a similar case that occurred three years ago from the mark of the flame left on the scene. It was decided to wash Kaonto Taihara (Taichi Saotome). Kaonto was eventually arrested for a fire of about Boya, and she was released half a year ago after serving a medical juvenile training school, but she couldn't get a foothold after that. However, on the night of Eve, Aoto and his friends find out that Tsubasa Washimi (Yuki Imai), the manager of an urban legend site dealing with the arsonist 'Angel of Fire', was also a child who survived the arson murder and headed to hear the situation.Around that time, Sei succeeded in reversing the situation with Rikuta's weaknesses. When asked if he was an 'angel of fire,' Ryuta replied that he was his senior, not himself. When Sei asked him to meet his senior, Rikuta took him to a room in a certain building and met him with Kanon. Sei will hear the relationship between Rikuta and Kanon and the truth of the arson murder case.

Totonou Kuno (Masaki Suda) goes to visit the grave of Yoshikazu Miyoshi (Asami Mizukawa). Then, there was Haruo Tenda (Kosuke Suzuki), and he thanked him for remembering the anniversary of the death of Kiwa, who was once a partner of Tenda. Tenda invites his high school classmates and guests to a mystery party at the villa and asks them to come. Also, I talked about the arrival of Seiko Furo (Sari Ito) at my lecture, and I heard from Furo that Sei was cooperating with the police, so I showed off mystery solving skills at the mystery meeting. I want you to do it. When Sei is having trouble answering, Tenda reassures him that he is just a part-time job to help carry luggage and clean up meals. And he added that he had only one request.On the promised morning, when Sei went to the meeting place, Tenda came to pick me up by car. I was surprised to see the bath light in the car. She told her that she invited her because Furo Hikaru was enthusiastic about her studies, and she told them not to tell the people who gathered at her meeting that she was a detective.Tenda's car running in the snow arrives at a mountain lodge covered with ivy. According to Tenda, it is called 'Ivy House'. It was Takakatsu Tachibana (Kuranosuke Sasaki) who welcomed the heavens and the men at the entrance. In addition, the owner, Kaoruhei Tsuta (Mansaku Ikeuchi) was waiting in the mountain cottage. Tenda, Takashi Tachibana, and Tsuta are high school classmates. Tsuta has also invited Della (Hiromasa Taguchi) and Pan (Kento Shibuya) to be guests of the Mystery Society.After allocating rooms, the mystery party starts at night. Tsuta began to talk about her death as the former owner of the villa fell off the balcony.

Sei learns of the fact that Yoshikazu Miyoshi (Asami Mizukawa) was once killed by a stalker at a mountain lodge where a mystery party was invited by Haruo Tenda (Kosuke Suzuki). Not only Kiwa, but the stalker is also dead from the toxic smoke of oleander in the fireplace. Before coming to the mountain lodge, Sei said, 'There is only one person who lie to the participants, so please take a look.' Talk about what you were asked to do. Then, Furo Hikaru was told by the heavens, 'I want you to see someone who doesn't lie.' Sei and Bath Hikaru begin to wonder if there is something wrong with Kiwa's case.The next morning, the awakened participants shovel the snow. When Sei asked Tenda about Kiwa's case, Tenda replied that although there was no evidence of a third party's invasion, he had always felt uncomfortable about the case. And Tenda asks Sei, 'I just want you to see the situation of the meeting without prejudice.' At that time, Furo Hikaru noticed that several branches of Oleander were broken.After shoveling the snow, when Sei and Furo Hikari are cleaning up the tools in the garage, a power outage occurs and the electric shutter does not open and is trapped. Sei takes out a flashlight from the tent that Takakatsu Tachibana (Kuranosuke Sasaki) put up in the garage. Sei and others are released by having the heavens open the door leading to the mountain lodge. The cause of the power outage was that the power line was cut off by the weight of the snow. Restoration will take until the evening, so I will eat lunch for the time being, and Sei will be asked to make curry. I noticed that there was something about the arrangement of observing the participants.

When Totonou Kuno (Masaki Suda) and Leica (Mugi Kadowaki) are enjoying a footbath in the greenhouse of Ohnei General Hospital, Manami Umezu (Atsuko Anami) comes and talks about how to spend the New Year. On the way to the hospital, when Sei, who saw the shrine, invited Leica to go to the shrine for the first time, Manami recommended that we go together. Leica also agreed, so Sei promises to go at 3 am on New Year's Day.From New Year's Eve, he spends his time in a small event with just two people, and joins Leica at the shrine at the appointed time. While being puzzled by each other's first visit to the shrine, Sei and Leica enjoy visiting the shrine, drawing fortunes, and enjoying the takoyaki at the food stalls. Seiko Furo (Sari Ito) and Yuto Ikemoto (Matsuya Onoe) see these two people. The two were driven into a New Year's patrol. When Ikemoto sees Leica, he notices something, but the bath light prompts him not to disturb them and returns to the patrol.Upon leaving the shrine, Leica invites her to eat yakiniku. She says that no store is open at this time on New Year's Day, but she has already found a yakiniku restaurant with Leica lit. When Sei looks into the store, there are Kunio Urabezawa (Keisuke Horibe), who seems to be the owner, and Sayaka (Mirai Shida), a clerk. When asked if Sei was still open, Kunio said he was trying to close it. However, Sayaka accused Kunio of not being able to return the customers early in the new year, and welcomed Sei and Leica. From Sayaka's words, it seems that Kunio has a relationship with her father and daughter. When you get to your seat, Leica tells you something in order with a code of numbers. It's annoying to check in 'Self-reflection record'. When she starts eating her roasted meat, Leica tells the story of her sister Chiyoko.

When Totonou Kuno (Masaki Suda) was thinking of going to an art exhibition to be held in Osaka, which he learned from Inudogaji (Eita Nagayama), a new serial murder case occurred at the Onei police station. I received a request for support. Seiko Furo (Sari Ito), nominated by Nariaki Aoto (Michitaka Tsutsui), heads for the investigation headquarters.The crime, which had already killed three people, is a bizarre case of abandoning her body like a crucifixion in the middle of an intersection. In addition, blood that does not belong to the victim is detected in the wound of the third body. Blood is consistent with the victim killed 22 years ago by DNA testing. It is Tokiko Tsuji, the 17th victim of a series of female assault murders by Gento Hagoku. The investigation headquarters is wondering if Hagaku, who had disappeared since he committed the 18th murder, has begun murdering again. However, the police officer Bizenjima (Eiichiro Funakoshi) says that it was not the crime of Hagoku. His subordinate, Toake Nekota (Wakana Matsumoto), agrees that the situation is different from the case of Hagoku. Furo Hikaru, who was listening to the conversation, was instructed by Bizenjima to form a buddy with Nekota.On the other hand, Iji was chasing a person named Jute in search of the truth about the death of Aiju (Mai Shiraishi). Then she finds out that Aiju frequently went to the warehouse district by her taxi during her lifetime. There, the darkness casino was held irregularly. After infiltrating the casino, I met Rumi Yokota  Natsuko) and was informed that Aiju was working at the casino.At the investigation headquarters, it is highly possible that the body was temporarily folded and carried. Nekota, who was listening to Furo Hikari, reported that a girl walking while pushing a suitcase was witnessed near her abandonment site. At that time, an anonymous person called Bath Hikari with a sauce for the incident.

After seeing the art exhibition, Totonou Kuno (Masaki Suda) boarded the Shinkansen returning to Tokyo. When I was about to eat his lunch, Megumi Seki sat next to him. Somehow embarrassing, he eats lunch and goes to bed early.
When she woke up from a nap and suddenly looked at her seat next to her, Hiroko was reading a letter. When I saw her stationery, I instinctively said, 'Nah, go, ni, haku, ru, na.' Sei apologizes to the surprised Hiroko. But she doesn't make sense to Hiroko because she doesn't say that in her letter. She teaches that Sei is not a sentence, but a rearrangement of the initials of the illustration. Then Hiroko showed the other letters in order.
Hiroko tells her that her letter is from her father. Hiroko, who lost her parents at an early age, was taken care of by her late mother's best friend. But recently, Hiroko finds her old letter hidden in her mother's closet, which she raised. That is the letter she was reading that her father addressed to her mother now. She had heard from her mother that her parents had died, but her father's letter asked her to return her Hiroko. At her address in her letter, she got her reply when Hiroko wrote her letter. Hiroko, who is about to get married, asks her father to walk along Virgin Road, and she says she's heading there.
However, the illustrations in her letter are filled with dangerous messages. There was a person who gradually moved from one seat to another while watching the situation of these two people. When he finally reaches the back seat, Sei calls out. It was a woman named Saki (Atsuko Takahata).
Around that time, Inudogaji (Eita Nagayama) and others helped Seiko Furo (Sari Ito) and others, and heard the truth about the death of Aiju (Mai Shiraishi) from Hiromasu Tsuji (Takumi Kitamura). However, there is a new mystery ...
