In Conan, people have a brain option system

Akikawa Kyusuke didn't know what was going on. He went to work in Kanagawa, a hundred kilometers away from Tokyo, and unexpectedly met the Shinigami elementary school student again.

Because he didn't want to be recognized by Conan, Akikawa Kyusuke did not choose to take off his hood during the performance.

However.

After Akikawa Kousuke heard the siren sounding downstairs this morning, he also guessed that another murder might have occurred.

Originally, Akikawa Kongsuke felt that this murder case had nothing to do with him anyway.

But when he heard the knock on his door, he realized that his idea was still a little too naive.

Since the suspicion is on him, the deceased is either an actor in the stage play, or his agent Miss Itakura Misaki.

The subsequent statement of the detective also confirmed that Akikawa Kongsuke's guess was correct.

The deceased was Masked Superman actor Takeshi Furusawa.

What a coincidence, this person came to look for me in my room last night.

‘When I was chatting with Takeshi Furusawa last night, I didn’t see any signs from him that he wanted to commit suicide. ’

‘Is it either an accident or another homicide? ’

Akikawa Kyusuke thought to himself, so he went downstairs with the detective who came to find him.

——

Conan, who was secretly observing the corpse, noticed someone coming down the stairs from the corner of his eye.

He looked in the direction of the sound.

Then after seeing Kyusuke Akikawa who came down with the Kanagawa Prefectural Police, a very surprised look suddenly appeared on his face.

After listening to Akikawa Kyusuke's self-introduction, Conan learned that Akikawa Kyusuke was the actor who played the evil mask.

‘Why is it this guy again? ! ’

‘And what’s going on with this guy? Why are there so many people dead? ’

‘And it seems that every time it has something to do with the deceased or the murderer. ’

Just when Conan was complaining in his mind that Akikawa Kyousuke's unlucky physique was comparable to that of Mouri Kogoro.

Suddenly he noticed Haibara Ai beside him. After seeing Akikawa Kyousuke appear, his eyes were fixed on Akikawa Kyousuke's face.

"What's wrong, Haiyuan, why do you keep staring at that Qiuchuan?"

Conan asked.

"I always feel that Akikawa Kyusuke looks a bit familiar. I seem to have seen him somewhere."

Hui Yuan Ai looked hesitant and said softly.

And after Conan heard Haihara Ai's complaints, he understood instantly.

‘This Akikawa Kyusuke is Ms. Yoko’s younger brother. Of course you will find him familiar. ’

Conan thought in his mind.

It should be said that not only Haibara Ai, but also most people in Japan will feel familiar the moment they see Akikawa Kyusuke.

After all, the sister who is related to Akikawa Kyusuke by blood appears on TV and various advertisements almost every day.

After Mitsuhiko Tsuburaya and Ayumi Yoshida met Akikawa Kyusuke,

There was a look of longing on the cheeks of the two little guys.

The former is because I like Evil Mask, and the latter is simply because Akikawa Kyusuke is a handsome guy.

"Hey-! You two!"

Moto Kojima suddenly felt unhappy when he saw the expressions of Mitsuhiko Tsuburaya and Ayumi Yoshida.

He used his fat body, which was at least twice as big as his peers, to block the sight of Mitsuhiko Tsuburaya and Ayumi Yoshida, then frowned and said:

"Didn't you hear? This person is an evil masker!"

"He must be holding a grudge against Masked Superman, so he killed Masked Superman!"

Mitsuhiko Tsuburaya and Ayumi Yoshida looked speechless after hearing Genta Kojima's words.

"Is Yuan Taiqiu an idiot? He is just an actor."

"Then he must have a motive for committing the crime! He might have killed someone because he was jealous that Masked Superman stole his protagonist!"

"this"

Mitsuhiko Tsuburaya and Ayumi Yoshida were immediately speechless.

Suddenly, I felt that what Genta Kojima said seemed to make some sense.

After Akikawa Kyusuke noticed Haibara Ai's gaze, he also glanced at her.

And at this glance, he also found a familiar feeling in Hui Yuan Ai.

'I always feel that this little girl looks a bit like Sera Masumi. Is it an illusion? ’

However, Akikawa Kosuke accurately found the source of the familiar feeling in Haibara Ai.

He thought for a moment, then looked at the Kanagawa Prefecture detective in front of him, and answered the other party's question truthfully.

Akikawa Kongsuke explained how he met Furusawa Kenshi.

And what happened last night when Takeshi Furusawa came to his room with a beer and chatted with him.

Akikawa Kyusuke did not drink the beer Furusawa Kenshi gave him, so he just chatted with Furusawa Kenshi who was drinking alone for a while and then sent him away.

While Akikawa Kongsuke answered the police's questions, he also learned the minimum information about the case from the few words revealed by the police.

To put it simply, Takeshi Furusawa was found at the bottom of the pool in the women's hot spring area.

And according to the judgment of a person named "Dr. Agasa", Takeshi Furusawa died of hydrogen sulfide poisoning.

Akikawa Kosuke didn't know who Dr. Agasa was, but he considered that since the Shinigami elementary school student was here, the conclusion drawn by the police was most likely the judgment made by the Shinigami elementary school student.

In other words, there is basically no need to doubt the truth of the cause of death of Kenji Furusawa.

‘If Kenji Furusawa died of hydrogen sulfide poisoning instead of drowning, then it means that he did not fall into the pool by mistake. ’

‘Although I have never been to the hot spring area on the female side, I also took a hot spring bath in the male area during the two days of rehearsal. The difference in the concentration of hydrogen sulfide in the air of the two pools should not be large. ’

‘Although the air near the hot spring of Kosen-an has a strong smell of rotten eggs, the only discomfort I felt was that my eyes felt a little irritated. ’

‘This means that the concentration of hydrogen sulfide in the air is at most about 0.001%, and the concentration of hydrogen sulfide must reach at least 0.07% to be lethal. This difference is not a little bit. ’

‘Due to geothermal activity and temperature changes, it is indeed possible that the concentration of hydrogen sulfide in the air near natural hot springs may suddenly increase, but the maximum amplitude of this change should not exceed double. ’

‘Then this cannot be an accident, it can only be murder. ’

Akikawa Sosuke made a judgment.

‘The murderer wanted to use the hydrogen sulfide gas in the air near the hot spring to cover up his method of committing the crime, but this method is too crude. ’

‘After a rough look, there was no resistance on Kenji Furusawa's body, so the murderer should have committed the crime when Kenji Furusawa was sleeping’

‘Because hydrogen sulfide is heavier than the atmosphere and there is no wind at the scene, hydrogen sulfide gas can easily gather in the low place. Since the police and the Shinigami elementary school students are so careless in conducting on-site inspections in the female hot spring area, it means that this is not the crime scene where the murderer committed the crime’

After a simple observation, Akikawa Sosuke made a judgment on the murderer's method of committing the crime and the timing of the crime.

At the same time, he also understood another thing.

That is, if the murderer intends,

the other party can kill all the residents on the same floor as Kenji Furusawa and the surrounding rooms at any time.

This naturally includes Akikawa Sosuke himself.

The murderer's motive for the crime is still unknown, but the degree of danger of what the other party did is extremely high.
