The bones and corpses of 13 children were found, commonly known as the "Haikawa Residence Incident".The mysterious sign that remained at the scene appeared again after 7 years.An incredible life together, the suspect known as “Father”, the six survivors of the incident, and the more or less hidden truth.The continuous mysteries lead people to unpredictable endings...

2017.In the basement of a certain mansion, 13 skeletal corpses were found.

The body should be that of a child, and there are distinctive hexagonal mysterious signs painted on the walls.Detective Saiki Hitoshi and others decided to confirm the identity of the body and track down the whereabouts of the owner of the mansion, Haikawa Shisan.

At this time, Kanon Hasui, who called Haikawa “father”, appeared.Kanon, who has neither a blood relationship nor a household registration relationship with Haikawa, saved herself as an abandoned baby and lived together as a “real family” until 6 years ago.Furthermore, it is said that there are 19 children living in the mansion.

After listening to Kanon's words, the police department's Gomi and Inspector Suzuki believed that the 13 corpses were likely to be one of the 19 children.However, Huayin said that her father was not the murderer——.

Time flies by and it’s 2024.On a busy street where young people gather, a girl is missing.Reporter Touko Mori, who was looking for the girl, came to Saeki, who was no longer a detective, and told him.

“Is that thing really over?”

2017.In Haikawa Shisan's home, the bodies of 13 children who were locked in the basement and starved to death were found.Haikawa abducted 19 children in the past and lived with them.

In addition to the 13 victims of the incident, six people including detective Saiki Hitoshi's younger brother Takimoto Sosuke and Rensui Kanon survived.Except for Kenryu Kamishiro, whose whereabouts are unknown, everyone denies Haikawa's crime.

However, the suspect Haikawa was arrested later.The characteristic hexagonal mark left over from the scene was painted on that hand...!?

At this moment, Hanayin was pushed down the stairs.Saaki rushed to the hospital, and Kanon told him that the prisoner who pushed me down was the prisoner in the Haigawa Residence incident.Then, in order to find “new prisoner”, request to continue the search.

7 years later in 2024.Reporter Touko Mori, who is looking for the missing runaway girl Mirai, asks Saegi about the “RICK” sign left at the scene of the Haigawa Residence incident.

Mori revealed that Mi Lai also had a tattoo with the same symbol on her body, “Has the incident really ended? ”asked this——.

Haikawa Juzo was arrested on suspicion of killing 13 children and hanged himself in a detention center.Detective Saiki Jin believes that Haikawa's actions are likely to protect the “real murderer”.

Saeki investigates alone and goes to the place where Rensui Kanon was pushed down.During the visit, it was discovered that during the time of the accident, there was a man with injuries on his face“...

On the other hand, headed by Kanon, the surviving children - Sosuke, Maya, Satoru, and Yuma gathered at Haikawa's house.

”It was the father who killed the children. It was impossible to imagine“. Hanayin looked at the expressions of the four people as if nothing had happened...

Regarding the ”real murderer“, Satoru mentioned the name of Kenryu whose whereabouts are still unknown. Kanon saw the ”Rika“ tattoo on Maya's back and recalled a certain memory” at the Haigawa mansion.

Then, the other children left, and Cangyou stayed there alone——

2024.Reporter Touko Mori is very concerned about the fact that the missing runaway girl Meira has “Rika”'s mark on her wrist.I'm thinking that this might have something to do with one of the children who survived the Haikawa Rei incident?

Sagi Jin showed Rensui Kanon a photo of a man“ with injuries on his face and asked her if she had any impression.This man was the person captured on the surveillance cameras around the police station after Haikawa Juzo's death.A man” with injuries on his face was also seen near the scene where Kanon was attacked.

The man holding a card sign in his hand was probably someone related to the Haigawa Residence incident.Sagi thought it was Kamishiro Kenryu.

Kanon said she didn't know if the man in the photo was Kenryu - but Kenryu told him about his resentment towards Haikawa and the children he lived with.

In addition, Kanon also said that she had heard Kenryu say that Haikawa had a “real child”.The murderer pointed out that he might be Haikawa's biological child, and said that if he traces Haikawa's past, he might be able to find clues to the truth of the incident.

Sagi heard important tips about Haigawa's hometown from Takimoto Sosuke.

Haikawa's past is revealed bit by bit, and Saeki and the others finally have to face a man with a scar on his face!

“Please don't give up...no matter what happens.”Hasui Kanon, who was hit by “the man with ”wounds on his face“, fell into a coma after leaving these words to Saeki Jin - Saeki felt that it was his responsibility.

Asuka Gomi appeared next to Sagi and told him that although he was chasing the man, he had not been found yet, and the search for the Haigawa Residence incident officially began.Moreover, the man and Haikawa Shisan may also be accomplices.

Gomi also advised Sagi: ”Be careful of confusion between public and private matters.% While telling about Hanayin’s unknown past, she also said that death has been surrounding her...

Sagi and Gomi finally discovered a shocking fact...

2024.Reporter Touko Mori visited Asuka Gomi of the Criminal Division.I wanted to ask Gomi about the Haigawa Residence incident that happened in 2017, but Gomi said that he didn’t want to talk about the incident that ended in that way——

Back in 2017.Takimoto Sosuke was arrested by detective Jun Suzuki.

Cangyou stared at Suzuki, “who are you?” he asked.

On the other hand, Sagi and Gomi found out that the paintings of Saturn that decorated Haigawa Residence were purchased by Suzuki. The diary written by Haigawa recorded the story of a child named “Toshi”, so they re-reported it to their superior, Kawaboshi..

Saeki called for Suzuki's personal safety to be ensured, but his superiors said that Suzuki's matter could be put on hold until definite evidence was obtained...

If a child grows up with domestic violence and will eventually commit violence, it is best to cut off the source of the chain.Living itself is wrong——.

After hearing what Suzuki (Daiki Sato) said, Saeki (Rei Narita) couldn't help but beat him.Even when his younger brother Takimoto Sosuke (Hagiwara Rihisa) tried to stop him, Saaki couldn't listen at all and kept beating him... At this moment, Gomi (Kuroki Misa) and investigators arrived at the scene!?

2024.Maya (Naka Manmei) was attacked and killed by someone on the roof of the building.In order to investigate the connection with the Haigawa Residence incident, Gomi talks to reporter Touko Mori (Mizuki Yamashita).This incident became an opportunity for Gomi and Sagi to reunite...! ?

“Kanon (Ai Yoshikawa), what on earth did you do...?”

Saeki (Narita Rei), who reunited with Kanon, couldn't help but ask.

Because whether it was the murder of Maya (Naka Manmei) or the disappearance of the girl, both incidents were suspected to be related to Kanon.

However, Kanon said that she no longer wanted to involve Mr. Saeki and left...

At the same time, a skeletal corpse was found near Haigawa's mansion.Touko Mori (Mizuki Yamashita) is worried that it is Mirai.Moreover, at the place where the body was found, someone had witnessed Kanon a few days ago...!?

A few days later.Sagi and Mori Touko heard what happened from Satoru (Matsumoto Reiyo).Satoru said that Kenryu (Kazuto Sadai) destroyed the entire family and talked about the Haigawa Residence incident.

As Kenryu's past becomes clearer, one of the survivors of the Haikawa Rei incident is in crisis.

In Kurado Village, the hometown of Haikawa Juzo (Kohinata Fumiyo), Sagi (Narita Rei) found Kanon (Yoshikawa Ai) and gave her the suggestion of “escape”, when a man with a bruise on his face appeared.Despite being attacked with a knife, Saeki managed to subdue the man...

“Huayin, run away!”

Sagi was shocked by the man's unexpected words.Kanon looked at Sagi sadly, then turned and ran away...!?

Just then, Gomi (Meisa Kuroki) arrives.The man was arrested on the spot for attempted murder - but he has been unwilling to reveal the motive for the crime or his identity...

On the other hand, the skeletal corpse found next to Haigawa's mansion was confirmed to be Kenryu (Kazuto Sasashiro).

In this case, Gomi discovered that Sagi concealed his meeting with Kanon at the cemetery and was told“You can't investigate further”...!?

Gomi decided to solve the Haigawa Residence incident personally, and she went to the home of Kenryu's mother Yoko (Hasegawa Kyoko).Yoko said that every year on his birthday, Jianliu would put yellow carnations at the door...

Appearing in front of Kanon (Ai Yoshikawa) is Kenryu (Kazuto Sadai)'s mother Yoko (Kyoko Hasegawa)!Kanon expressed her gratitude to Yoko for coming to Haigawa Residence, and told Yoko: “I want to end everything here completely...”!

On the other hand, the J side confirmed that Yoko had appeared on the road near the accident site of Yuma (Yuriya).Gomi (Meisa Kuroki) and Kawasaki (Toru Nomaguchi) began to investigate Yoko's whereabouts, but Yoko was neither at home nor at work.

At the same time, Saeki (Rei Narita) and Touko Mori (Mizuki Yamashita) finally learned the truth about 13 years ago recorded in Haikawa (Fumiyo Kohinata)'s diary...!

After all, what happened at Haigawa Mansion 13 years ago?Can Sagi and Kanon meet again?

What is the truth behind the series of events starting with the Haigawa Residence incident in 2017!?
