However, because of this ability, she is alienated from the rest of the village.Although her mother Urabe Fumi (Mayumi Wakamura) protected Kanoko, Kanoko decided to leave the village in order not to cause trouble to her mother.

The place where Kanoko came was Kujyuye Town.People here communicate with lies.Despite this, in search of a job, Kanoko came to the cafe “Rose” which had a “urgent recruitment notice for a waitress”.However, the waitress Lily (Eri Murakawa) told her that a new employee had just been decided.

At this time, Tsuyoma Suzuka (Eoji Suzuka), who opened the "Suzuka Detective Agency", took his close friend Kaoru Hazaki (Ryosuke Ajigata) who is a police officer to clean the Inari Shrine.Faced with Duanzaki's doubts about why the police were asked to help, Zuoma replied that it was related to people's life and death.In fact, the landlord of the office that Uuma rents also manages Inari Shrine, and he came to help with the cleaning in order to reduce the rent.

When Uma and Tasaki arrived at the shrine, they heard moans like wild dogs and a woman's "Don't come here" sound.They entered the bushes where there was movement and saw Kanoko having a quarrel with a cat.It turns out she was trying to protect the kitten from being attacked by the dog.At this time, due to hunger, Kanoko fainted.Tasaki took the fainted Kanoko to the small restaurant "Kurata's House" run by Kurata Tatsuo (Okura Koji) and Kurata Yoshie (Isoyama Sayaka).There, Kanoko overreacted to lies told by Taro (Shibuya Soji), the son of the Kurata family...

Urabe Kanoko (Honoka Matsumoto), who has the ability to detect lies, is alienated and disgusted by the people around her. Her mother Fushimi (Mayumi Wakamura) also stayed in her hometown, and she embarked on the journey alone.The place we arrived at was a place called Kujyuya Town.Kanoko, who fell to the ground due to hunger, was rescued by a man named Susuma (Eoji Suzuka) who ran a detective agency.Kanoko originally wanted to hide her abilities and continue living, but after knowing the truth, Soma, who was not surprised, invited her to become a detective assistant.At this time, Uma accepted the request from everyone in the office to deliver something to the Fujishima family, so he went with Kanoko.

After arriving at Fujishima's house, their wife Yukino (Sakurai Junko) gently welcomed them both.Then, with a call, the daughter of the Fujishima family appeared.She was Chiyo (Yuki Katayama) who scolded the two of them in the car where she had a quarrel with Souma and Kanoko a few days ago.Both parties were taken aback, but Chiyo, who was addicted to detective novels, saw the appearance of the two of them and immediately concluded that they were poor people, and pointed fingers at Yukino unceremoniously.

At this time, the Fujishima family's driver Kokichi (Miyazaki Akito) appeared holding Chiyo's shoes.Chiyo took the shoes and planned to go to the theater alone, but Yukino insisted that Kokichi drive her.After Chiyo left, Yukino told the detective, Souma, that he had something to ask for.After the horses nodded, the head of the house Yukihiro (Tetsuta Sugimoto) appeared.Yukihiro showed Souma a piece of toilet paper that had been stuffed into the entrance door. It said "Fujishima Yukihiro, I hate you so much, don't forget".When Yukihiro said that the prisoner was distressed, a woman rushed in with new toilet paper.It was written on the toilet paper, “We have kidnapped Chiyo. If we want her to return safely, we must prepare the money...”

Kanoko Urabe (Honoka Matsumoto) works as an assistant in the detective agency of Yosuma Suzuka (Eji Suzuka).Kanoko was cleaning the office, and the room was full of rags.Because the poor detective's right-hand man got everything he wanted from others.Then, Zuoma remembered something and took the tattered things in the cart to the street with Kanoko.

Came to the old props store.Zuoma wants to use Kanoko's “ability to detect lies” to prevent her from bargaining for tatters.After Kanoko saw through the lies of the shop owner (played by Maenoya Tomoya) about the purchase price, Soma successfully sold the rags at a good price.At this time, the shop owner told the two that he was drunk on “60th Street” and his wallet was stolen.

One day, Youma's friend, detective Kaoru Hazaki (played by Ryosuke Tomokata), comes to visit.Although Zuoma treats Xin rudely, he is envious of Shikanoko who has no friends.Zuoma asked about the main points of the interview, and Tazaki showed him the photos from the magazine report.In the photo of the newly opened restaurant in “Rokujuban Street”, Tasaki said that the beautiful waitress (played by Kurumi Nakata) in the photo may be “Matsuha Peony-kun”.

A few days ago, Taranzaki fell down due to food poisoning after eating the dish given by Yuuma.After the left and right horses left in an exaggerated manner, a woman took care of Tazaki.Although Tasaki had never seen the woman's face, he remembered that the kimono had a pine and peony pattern, so he wanted to express his gratitude.At that time, Zuoma, who saw the female appearance and compared it with the photo, denied that it was completely different.However, Kanoko knew that Roma was lying...

In Kujuya Town, on the bustling avenue in the early morning, Tsukushima (Eoji Suzuka) and Kanoko Urabe (Honoka Matsumoto) are heading to the station.Zuoma told Kanoko who was out on the train: “ couldn't pay the rent and just ran away in the morning and evening.”

At this time, Zuoma noticed the suspicious man and used Shi Naoko's ability to distinguish lies to expose Zhiyin.The man ran away, but was tripped by the woman present and caught by those around him.The woman who caused the offence by placing her foot is an acquaintance of Uma, Kaoru Hazaki (played by Ryosuke Tomokata)'s sister Masa (played by Kitano Kii).

Ya knew that Zuoma and others were on the run at night, so he invited them to go on an interview trip together.Shikanoko was very scared when she heard that Miyabi was a reporter for the ghost story magazine - Demon Realm Detective. Soma also wanted to refuse, but Miyabi said that she would pay this month's rent, and Soma immediately agreed.

The place where Miyabi was interviewed was Ayao's house, which was known as the “Doll House”.The Ayao family has a strange custom. In order to pray for the healthy growth of their only daughter, who was born with a frail body, they raise a doll made when the daughter was growing up like her daughter.Now, the owner and his wife died in a shipwreck, and the only daughter Shinoko (played by Rin Kataoka) inherits.Pinzi looks like a doll, and there are some strange rumors about it.

Among them, Shibata (Sadoi Kenta) led the way for the left and right horses who arrived at the local area.According to Shibata, the maid Ina (played by Ryo Matsuura) snooped into the “humanoid room” in the house and found someone's body.Ina hurried to Shibata's house. Shibata went to his room with detective Seiichi Terayama (his real name was Fuzo) and found that the body was a doll. After that, Ina fell to the rocky ground and died... In order to find out the truth of the incident, Shibata and Soma, Shikanoko, Masaru and Naiko meet...

Tsuyoshi Suzuka (Eoji Suzuka), who opened a detective agency in Kujuya Town, and detective assistant Urabe Kanoko (Honoka Matsumoto) continue to work.As an assistant, Kanoko has been thinking about hoping to be able to help her husband as soon as possible.At this time, the landlord of the office asked Kanoko to find a cat.Although the cat was found successfully, Zuoma planned to use the cat as a negotiation material to see if the rent could be waived or if it could be exchanged for money. Kanoko was shocked by Zuoma's move.

In this way, the two returned to the office and found Chiyo Fujishima (Yuki Katayama).“Nothing good happens once you get involved”, and Uuma and Kanoko, who wanted to escape, hid in Wakatakeza's practice (sacrifice team).However, Zuoma was stopped by an acquaintance, and Chiyo discovered Zuoma.Chiyo ran towards the left and right horses, but collided with a man and fell down.The man left after confirming that Chiyo was not injured. Kanoko picked up the bag that Chiyo dropped.Then, in order to help Chiyo, whose clothes were messy, get dressed again, the group returned to the office.

After getting dressed, Chiyo took a keen interest in the detective agency.She opened her bag to record the appearance of the office, but found an unknown hand mirror inside.Chiyo speculated that the hand mirror might have been dropped when he hit it just now, so he offered to give it back to the man.Based on the man's attire at the time, Zuoma suggested that she go to the mason's place to find out, and asked Kanoko and Chiyo to go together.Chiyo said excitedly: The girl detective team is established!%, left the office with great enthusiasm.

Soon, Kanoko and Chiyo found a mason's shop, found out that the man's name was Toshiichi (Hashimoto Jun), and successfully returned the hand mirror to him.However, later it was discovered that there was a pickpocketing incident in the surrounding area.After hearing a woman say that a hand mirror had been stolen by a young man, and the characteristics were consistent with the hand mirror in Toshi's hand, Kanoko and Chiyo once again searched Toshi as a pickpocket.

However, the investigation of the case has reached a deadlock.Tatsuzo Kurata (Koji Okura) who was listening in suddenly interrupted and mentioned that there seemed to be a “ghost mansion” deep in the depths of Thirty-third Street.Ten years ago, Adachi, a painter who lived there, murdered his wife and disappeared.There are also rumors that the ghost of his murdered wife haunts the house.

At this moment, Yoshie (Sayaka Isoyama) realizes that he left his shawl in the hospital.Kanoko said: "I always eat here for free anyway", so she offered to go to the hospital to get the shawl back.After hearing this, Dazao said that some ingredients would be added for dinner, and Zuo Ma also decided to go together.

When Uma and Kanoko retrieved their shawls from the hospital, the ward became commotion for some unknown reason.It turns out that Lily (Eri Murakawa), a waitress who works at “Cafe Rose”, is sternly questioning Kirino Kanji (Mario Kuroba), a regular customer of the cafe, in the ward.The night before yesterday, Lily and Guanji made an appointment to go to the movies together, but Guanji never showed up and failed to make the appointment.Guanji explained that on his way to the movie theater, he saw a female ghost at the “Haunted House” on 30th Street.

At the same time, Lily, who was waiting for Kanji in the cinema, was approached by a woman (Nozomi Bando) who claimed to have spent the night with Kanji.After learning that the woman was looking for Guanji, Lily was furious and decided that Guanji was a scumbag who broke the promise.After Shikanoko confirmed that what Kanji said was true, he winked at the horses on the left and right.That night, Zuoma and his party embarked on a journey to the “Haunted House”.
