Tokyo, the shady intelligence of private detectives

A tenant who's not thinking straight!

Masahiro Hanyu now possesses the ability to remember everything he sees; he can recall every word and action of every tenant.

"The couple in room 101, the husband's speech was a little slurred, probably because he had been drinking, his face was a little red."

"The sheet metal worker in room 102 had fingers that trembled habitually."

"The middle-aged man in room 201 looked at me strangely; he might be attracted to men!"

……

Masahiro Hanyu could recall every detail of the tenant's words and actions clearly.

Satsuki Yui listened quietly, occasionally nodding slightly. Yuzuru's memory seemed to be somewhat extraordinary; she hadn't noticed it before.

After Masahiro Hanyu finished speaking, Yui Satsuki's peach blossom eyes showed a look of confusion.

"Could it be that Officer Yamamoto's judgment was wrong? According to Yuzuru's recollection, there wasn't a single tenant who needed to be watched."

When Masahiro Hanyu spoke, his eyes remained fixed on Yui Satsuki.

At this moment, he was able to deeply understand those four words: "beauty is food for the eyes".

Satsuki Yui raised her eyes. This young clerk, who used to always sneak glances at her, had never dared to look her in the eye so boldly.

He seems to have become much bolder since accepting the commission to investigate.

Perhaps when men experience more and gain more confidence, they will change in some ways.

As a detective in a detective agency, being bold is always a good thing.

"Officer Yamamoto's request was only verbal; there was no written authorization," Yui Satsuki explained in detail.

"There's a reason he asked me to investigate."

"Three years ago, when those five suicides occurred, all the evidence pointed to suicide."

"At the time, the district police station suspected homicide, so they transferred all five suicide cases to SIT, and Officer Yamamoto was in charge of the investigation."

"I had already resigned from the Metropolitan Police Department at that time and was not involved in these cases."

Masahiro Hanyu was somewhat curious about President Satsuki's transformation from a police elite to a private detective, but he wouldn't ask why, as that might be the president's private matter.

"After careful investigation, Officer Yamamoto concluded that the five victims did indeed die by suicide."

"The death of Keiko Tanaka is similar to the five cases three years ago, and the investigation has concluded that it was a suicide."

"With the increase in suicide cases in recent years, in order to avoid causing unnecessary panic, the Metropolitan Police Department leadership has ordered Officer Yamamoto to terminate the investigation."

"But Inspector Yamamoto was not satisfied. He came to me, hoping that I would take advantage of the opportunity of Keiko Yamamoto's death to thoroughly investigate the case. He promised to provide appropriate support in secret."

"Hanyu-kun, in recognition of your outstanding work in investigating the tenants, I am formally requesting that you become my partner to investigate this case together."

Masahiro Yuzuru sighed inwardly. The case that SIT couldn't solve three years ago, he hoped to use this opportunity to find out the truth, but it might be a long process.

As long as he can't fulfill the commission, he'll have to continue working like a beast of burden without receiving any commission.

Fortunately, he had an intelligence network.

A faint light screen appeared before Masahiro Hanyu's eyes.

[Privacy Intelligence Reward System Launched]

[Host Level: 1, can obtain three random pieces of information]

[Respondent identified: Keiko Tanaka]

[Information 1: Keiko Tanaka enjoys watching the TBS midday program "Healthy Living"]

[Second piece of information: The manager of the Nishi-Azabu Twin Stars Ballroom was once Keiko Tanaka's dance partner when she was young]

[Intelligence 3: VIV Short Pure Copper Raised Arm Pendant Machine]

Satsuki Yui coughed lightly. Yuzuru was not only bold, but also quite presumptuous, staring directly at her without any restraint. She had to give him a proper reminder.

At that moment, Masahiro Hanyu was staring at the light screen in front of him, unaware of Yui Satsuki's misunderstanding.

"President, then why should we be wary of tenants who are mentally unstable?"

Satsuki Yui had to turn slightly to avoid his gaze.

"For the past three years, Officer Yamamoto has never given up investigating the reasons for the suicides of the five victims, and he now has some leads."

"Like the five victims from three years ago, Tanaka Keiko may have died from a mysterious drug."

"This could be a synthetic drug that cannot be detected by current autopsy techniques."

"The origin of this mysterious drug is unknown; although it exists, it has never been able to be detected."

"It is said that this mysterious drug can cause people to lose their senses. Tanaka Keiko usually has the most contact with her tenants, so she asked Yuzuru to check it out."

"Based on the situation three years ago, Officer Yamamoto deduced that since there was a first victim, there might be other victims in the future."

Masahiro Hanyu nodded. "I think I understand. Inspector Yamamoto was worried that having him investigate might alert the killer, so the president assigned me to this task."

Satsuki Yui remained seated sideways. "Hanyu-kun is right."

"President, how do you plan to conduct the investigation? I'll follow your instructions."

Although Masahiro Hanyu obtained three pieces of information, he could not present them without any evidence, and Yui Satsuki might not believe him.

His official title was partner, but he was really just an assistant, and following orders was his duty.

Of course, in order not to be taken advantage of for too long, he would reveal the three pieces of information one by one when the opportunity arose.

"Hanyu-kun, what are your thoughts on this request?"

As expected of a leader, she first throws the problem to her subordinates, and then she summarizes it.

Masahiro Hanyu appeared to be deep in thought. "The five people who committed suicide three years ago have already been thoroughly investigated. It would be very difficult to find clues from them again, so we should start the investigation with Keiko Tanaka's personal situation."

Yui Satsuki opened the drawer, took out a folder, and handed it to Masahiro Hanyu. "This contains information about Keiko Tanaka."

Masahiro Hanyu took the folder and opened it; the contents were detailed.

Name: Keiko Tanaka

Gender: Female

Date of birth: February 22, 1949 (Showa 24)

Date of death: August 26, 1992 (Heisei 4)

Age at death: 42 years old

Place of birth: Setagaya Ward, Tokyo

Address before death: Detached house in Yoyogi 2-chome, Adachi-ku, Tokyo (lived alone after being widowed)

Blood type: O

Height: 158cm

Weight: 82kg (obese, moderately overweight)

Masahiro Hanyu's gaze fell upon Keiko Tanaka's past experiences:

1965: Graduated from Tokyo Metropolitan Sakuragaoka High School, where he was a core member of the school's dance club.

1967 (age 18): Won the runner-up title at the All Tokyo Youth Latin Dance Competition.

1968-1975: Active as a professional Latin dancer, participating in commercial performances and small competitions in Tokyo and surrounding cities, and also teaching short-term Latin dance hobby classes.

1975: Due to a worsening of an old knee injury and gradual weight gain, she completely withdrew from the dance industry, ending her dance career.

Masahiro Hanyu thought of a second piece of information: "President Satsuki, Latin dancers usually have partners, so their relationship must be quite close..."

"I checked. Tanaka Keiko's dance partner is named Inoue Kazuhiko, and he's currently the manager of the Nishi-Azabu Twin Stars Ballroom," Satsuki Yui interjected.

Yuzuru Masahiro's eyes lit up: "President, I suggest we secretly investigate the Twin Star Ballroom; we might find some clues."

Satsuki Yui frowned: "The Twin Star Ballroom is actually an underground casino. Men can only enter with a dance partner."

Yuzuru Masahiro said solemnly, "President, then I'll have to trouble you to be my dance partner this time."
