Sumiko Sato is a drinking princess who has been hanging out in Kabukicho all year round, and of course, if the clam angler is generous, the wine princess can also provide better service.

And her other identity is one of Kobayashi Harusui's roommates.

In the early hours of early September, Harusui Kobayashi, who was returning home from work in Kabukicho, took a train to Shibuya Omotesando, and then walked along Omotesando to rent an apartment.

When passing through the area of Shibari Park, he was followed and killed by the murderer, exposing his body on the side of the road.

Shibara Park was originally a construction plot in the Tanishen Redevelopment Zone, but it was acquired by the Suzuki Foundation and planned to expand, but due to various factors such as funding and policy, the expansion plan was put on hold, and Shibara Park, which was halfway through construction, was abandoned.

There are rumors that the so-called broken capital chain is purely an excuse, and the real reason is that there are frequent accidents among migrant workers here, and there is a suspicion that something unknown is shrouded, so the expansion plan is frozen.

In short, Shibara Park is a very desolate place, so after Kobayashi Harusui was killed, no witnesses or surveillance probes were found at the scene except for a small amount of the murderer's hair.

The dossier wrote that after Kobayashi Harusui was followed and violated by the murderer, he wiped off his neck with a knife from the back, and the blood spurting out of the carotid artery drew a 120-degree half-arc on the ground, which was very terrifying.

When it was found, the lower half of the body's clothes were thrown at the curb stone five meters away, and like Nanao Toyama, who was killed in the Hanging Garden residential area, Kobayashi Harusui fiercely resisted in the process of being held hostage.

She had multiple bruises on her arms and torso, the leather bag she was carrying was ravaged to pieces, and the murderer's hair was also found on the purse, suspecting that Kobayashi Harusui may have used the leather bag as a weapon to fight back.

Unlike the three deceased who died in their sleep, the defensive wounds and traces on the bodies of Nanao Toyama and Harusui Kobayashi seem out of place, and it is precisely for this reason that Kamio Kaede thinks that the investigation of the eucalyptus is too blind, and the bold profile of the so-called double schizotypal personality is too advanced and rash.

After DNA comparison, it was confirmed that the hair shot down by Kobayashi Harusui's leather bag was consistent with the hair at the scene of the Qixu Eucalyptus in the distant mountains, and the murderer was the same person.

Kobayashi Harusui's residence was quickly searched by the police, and the two roommates were not heard from, which is normal, although most of the customs and industries in Kabukicho are within the scope of the law, but that is under the premise of the protection of the Hey Gang.

Almost all cowherds and princesses who work in the red light district have to pay protection fees to the Sanwakai, Watanabe-gumi, etc., and some people are indiscriminately fishing in the troubled waters of Kabukicho in an attempt to evade the high protection fees, so they are no longer legal, and it is normal for them to flee when the police search their apartments.

As soon as he got the news of Kobayashi Harusui's roommate, Okuji immediately contacted the other party, but out of fear of the police, Sumiko Sato was reluctant to show up, and hung up the phone many times, terminating the technical positioning of the police.

In desperation, Okuji entrusted the informant and Hiko to be an intermediary, although Kazuhiko had washed his hands and did not have much contact with the affairs of the road, but the face was still there, so Sumiko Sato happily agreed to the request for a meeting.

But the meeting took place in a café on Neon Street in Yansan, and the other party refused to meet at the police station.

In order to prevent Sumiko Sato from being embarrassed in front of the two male policemen, he specially called Nana Ogino, and the three of them went to the café called Moonlight Tea House to wait for Sumiko Sato.

The café is located on the northernmost side of Yensan Neon Street, turn left from Exit 1 of Shimbashi Station on the Ginza Line, and walk for 5 minutes.

The decoration of the façade reveals a strong Showa style, and there are several warning signs in Chinese, English and Japanese - 'No business meetings', 'No loud noises', 'No smoking', 'No reading', 'No photography', 'No opening laptops'......

As soon as you enter, the aroma of coffee and bread comes to your face, and the foyer is filled with a shimmering fish tank and a majestic rockery.

Kamio Kaede ordered three cups of coffee while holding the menu, and blood flowed in his heart, this Zuo Fuji Sumiko is really good at picking a place, a cup of coffee costs 3,000 yen, why didn't the boss grab it?

In the end, Okuji ordered a cup of deep frying, Nana Ogino ordered a cream latte, and Kamio Kaede ordered a cup of black tea, which was brushed off for 6,500 yen, and the distressed Kamio Kaede almost suffocated.

"Senior brother, drink coffee...... Can you help me ask if you can issue an invoice? ”

"Didn't you just get a bonus, why are you crying poor again?"

"Buy a car, refuel, maintain, and how expensive the price of oil is now!"

Although the coffee is expensive, some small desserts are served for free, such as cookies, strawberry cakes, waffles, pafay, and fruit tarts.

Kamio Kaede showed off two large pieces of strawberry cake very competitively, and touched the slightly bulging little belly, which was regarded as a chat to comfort the thousands of oceans that were ruthlessly swept away.

While eating snacks and waiting for Sumiko Zuoto, the three of them chatted about the eucalyptus, and then talked about the murder weapon.

Kamio Kaede said: "None of the murder weapons were found at the eucalyptus scene of the five fatal eucalyptus, but judging from the wound marks, the resistance of the distant mountain Qixu and Kobayashi Harusui was the most intense, so the traces were more obvious.

The murderer should use a sharp weapon such as a dagger when killing people, unlike fruit knives, bullet yellow knives or butterfly knives, well...... It was supposed to be a military dagger, a saber with more pronounced features than a fruit knife.

Based on Kobayashi's wounds, Dr. Nakamura judged that the saber was about 20 centimeters long, with a partially short serrated structure on the blade, with a partial arc, narrow at the front and back, wide in the middle, and possibly an integrated lock and stop pin.

Given that the wound did not come into contact with any hard human bone, there were no blade fragments to compare, and it is speculated that it should be high-carbon steel or chrome-plated alloy steel. In short, the knife edge left by the wounding and murder did not have any mud and water, and it was a military-grade sharp dagger. ”

Hearing this, Nana Ogino spoke and asked, "What is the shape of the tip of the sword, sword-shaped, conical, spear-shaped, planed-shaped, or raised?" ”

"It's probably somewhere between a sword and a cone." Kamio Kaede replied, "You know knives?" ”

Ogino Nana raised her head proudly, "Whether it is a common controlled knife on the market, or a military dagger, I can basically distinguish eight or nine from ten when I look at the wound, and the murder weapons that our Nanya Dangerous Goods Management Department can't identify are all found by me, and today you have met an expert." ”

Kamio Kaede hurriedly gave a thumbs up, "If you know both off-road and saber, I have to wonder if you are an agent, you have a wide range of knowledge." ”

Ohino Nana smiled and went back to the topic: "Sword-shaped and cone-shaped military daggers, with an integrated lock and stop pin, there are actually quite a few sabers of this type, I can tell you more than twenty kinds with my fingers, it is difficult to tell which saber the murderer will choose." ”

Ao Si asked on the side, "The murderer can get a military dagger, does he have a military background?" Veterans and the like? ”

Nana Ogino shook her head, "It's hard to say, the murderer may have bought it from the black market, after all, you can get any contraband on the black market." Or maybe it's a member of a saber club, where there are many ways to get military daggers.

It is also possible to steal, pick up, and rob, and the last possibility is that he has a military background, anyway, a saber is better than a Type 89 rifle. ”

Ao Si asked again, "Judging from the scene of several deaths, the murderer was basically solved with a knife, but the body did not leave any blade fragments, which is very unreasonable, could he be a master of using a knife?" ”

Nana Ogino pondered for a while, not sure, "Normally, even if a good knife stabs into the body, even if it can't touch those hard bones, it is difficult to pull it out intact, and there will be some fragments left on the corpse more or less.

Perhaps the murderer is in the profession of a butcher or a doctor, and he wields a knife like a cow in a daze......"

She gestured with a knife and continued, "Or maybe this murderer was so lucky that when the murder weapon pierced the deceased's body, he perfectly avoided the bones...... But if the five lives are like this, it's a bit unbelievable.

In the case of close-quarters assassination, even if it is a veteran who has been on the battlefield for a long time, he can only have a rough judgment of the point of falling - it is a matter of a moment to stab in and pull out, and he does not care about adjusting the position to avoid the bones.

After the blade pierces into the body, any technique will not work, and whether the tip of the knife will be broken by the bone depends on the material of the blade and personal luck. Especially if you have a few fates, either you are lucky, or the quality of the saber is excellent! ”
