In Conan, people have a brain option system

Conan was driven a little crazy by Akikawa Kyusuke.

He suddenly felt that Akikawa Kyousuke's mother kept this extremely stupid Akikawa Kyousuke at home, which was actually a kind of protection for him.

Moreover, if Akikawa Kyusuke's sister is Okino Yoko, the most well-deserved sister in the Japanese entertainment industry today.

I'm afraid it's just because of Akikawa Kyousuke's face.

It will be eaten up and wiped clean in minutes.

'But speaking of it, if Akikawa was really smart, how could he have made Koichi Saihara want to kill him in the Imperial Theater? ’

'Kousuke Akikawa was able to steal the role of Sae Otani from Koichi Nishihara and then go to thank Koichi Nishihara. This is not something ordinary people can do. ’

Conan completely equated Akikawa Kyusuke with an idiot in his heart.

It is obviously the easiest way to shoot Akikawa Kyusuke with an anesthetic needle, and then use the bow-tie voice changer to convey the reasoning to the criminal police at the scene through Akikawa Kyusuke's voice.

But after all, this case had just begun, and he didn't even see the suspect.

So Conan also gave up the idea of ​​using anesthetic needles.

'What should I do? I went out to take a bath without taking my phone, and the only adult I know around me is a guy who drools.'

Just when Conan was at a loss, thinking about whether to risk exposing his reasoning ability and run to alert the Kanagawa Prefecture Police Department to make up for it.

The sound coming from the door of the hot spring hotel made Conan instantly excited.

"Sorry, there is a case here, so tourists are not allowed to enter for the time being."

"I know, that's why I came here."

"ah?"

"My name is Masumi Sera, and I am a detective. I believe I can help the police officers."

Sera Masumi's slightly neutral voice was extremely pleasant to Conan's ears at the moment.

He hurriedly ran to the door and shouted to Sera Masumi:

"Miss Sera! Miss Sera!!"

Sera Masumi heard this and looked behind the detective.

The girl's delicate cheeks did not show the slightest surprise at seeing Conan.

She didn't know in advance that Conan and his party came to Hakone to soak in the hot springs.

Instead, Masumi Sera, who was riding a motorcycle, was attracted by the police car with flashing lights, and saw a familiar yellow first-generation Beetle here.

So she guessed that Conan, Dr. Agasa, and the little guys from the Junior Detective Team should be in this hot spring hotel.

"Miss Sera is a very famous detective in Tokyo. She has helped the Metropolitan Police Department solve many cases!"

"If the police officer doesn't believe it, you can search Miss Sera's name on the Internet!"

Conan ran to the door and said to the detective.

After hesitating for a moment, the criminal police officer finally decided to make a supplementary report to the Okamura Police Department first.

After waiting for his boss's approval, he allowed Sera Masumi to enter Kosen-an.

As Conan and Sera Masumi were walking towards the crime scene, he also told Sera Masumi what happened today.

"Akikawa Kyusuke is here too?!"

Sera Masumi, who had never expressed much emotion after hearing about the decomposed corpses, showed a rather surprised expression after hearing that Akikawa Kyusuke was here.

"Yeah, he happened to take the job of performing here, so he came here."

Conan said.

‘What a coincidence’

Sera Masumi thought in his heart.

She really didn't expect that she would come to Hakone from Tokyo to investigate Akikawa Kyusuke's mother.

It turns out Akikawa Kyusuke himself happened to be here.

"We meet again, Mr. Akikawa."

"Hello."

Sera Masumi saw Akikawa Kyusuke respond to his greeting with a stiff expression.

She knew that in Akikawa Kongsuke's heart, he probably still had a lot of concerns about herself and Conan.

'Akikawa, if you wait a little longer, I will be able to find out the murderer of your mother soon. ’

Sera Masumi thought in her heart, and then walked into the men's hot spring area without any sloppiness, and came to the pile of bags containing various broken limbs.

After quickly scanning a few bags, she then looked at the Okamura Police Department.

"Hello, I heard that this bag with arms and right legs was floating on the water at first."

"That's right."

Okamura nodded.

"The other bags sank to the bottom of the water, but this bag floated on the water, indicating that there was excess air in it."

"This indirectly reflects that when the murderer was bagging, he was very pressed for time and was very panicked, so he wanted to quickly dispose of the body, which revealed a flaw."

"I just saw the camera facing the door of the hot spring hotel. The most reasonable scenario is that in order to avoid surveillance, he chose a hot spring area where there is no surveillance nearby to dump the body."

"So the crime scene and the person who dumped the body should be inside the hot spring hotel."

After hearing this, the Okamura Police Department officer suddenly felt that Sera Masaki's words made sense.

He quickly ordered down and asked a criminal police officer to check the surveillance, while other police officers went to search the rooms one by one.

Since it is such a bloody and cruel act as dismemberment.

The other party should still leave a lot of traces.

Immediately afterwards, Sera Masumi began to carefully observe the stumps in the bag.

A policeman came forward and was about to hand a pair of gloves to Masumi Sera.

Then Masumi Sera took out a pair of white gloves from his pocket and put them on.

Facing the body parts that even the detectives were embarrassed about, Masumi Sera reached out and grabbed the body parts to observe them.

"The cut surfaces of all the wounds are very neat, and there are basically no signs of multiple cuts."

"This shows that the murderer must have been very strong and could cut the body from the joints with one knife."

"But if you look closely at the body, you can find that although all the body parts were cut off with one knife, the cut surfaces between the body parts are different."

"Just like the cuts on the neck and wrist, the blades were cut perpendicular to the body."

"And the cuts at the ulnar joint between the upper arm and forearm, the femoral tibia joint between the thigh and calf, and the hip joint between the thigh and torso, all show an inclined angle."

"Say The angle of the knife was tilted towards the body."

"I think this is not a coincidence."

"It should be that the murderer was unable to cut these parts normally due to some special circumstances."

"The parts where the murderer cut were basically all the "movable joints" that the human body controls flexion and extension."

"Plus, the time of death of the deceased has exceeded ten hours, so I thought of a possibility."

"That is, the murderer actually cut all the movable joints to cover up the posture of the deceased that could not be changed due to rigor mortis after death."

Sera Masumi looked at the remains in the bag and spoke.

In Japanese, "Miss" and "Mr." are both "mul", and the gender difference cannot be heard. The description in the book is only to reflect the speaker's judgment of the other party's gender.
