Refuse to allow Conan to join the main storyline

Gin simply didn't believe that Mello would turn against him over such a trivial matter.

As expected, Koizumi was choked by his words, and then he slammed the shotgun on the table with an angry look on his face: "Anyway, you are not allowed to do that! If you dare to do anything, I will, I will... take back all the helpers I lent you, and you will only have trash to use! Then I will pile all the undercover agents sent by various forces around you, and you will just play with mice every day! Humph!"

There was no threat of any killing power, but it was full of sarcasm that was about to overflow...

The corner of Gin's mouth twitched.

He reached out and tapped the black box: "Are you sure this thing won't be used by the other party? I don't trust any random person."

"I am sure!"

Koizumi said in a serious and decisive manner: "You don't have to believe in anyone, just believe in me. I say no, and I mean no!

"Both of you are important and indispensable parts of my plan, and I may need your cooperation in the future, so don't make things difficult for me!"

Gin looked at her in silence for a long time: "Aren't you tired of playing with two boats?"

"Tired, but only temporarily. It will be over soon."

...soon?

Gin's heart moved.

…Well, it’s already June.

There is less than half a year left before the deadline she promised at the special talent recruitment fair.

In fact, Gin's meaning was very clear, but Koizumi still asked again out of concern.

"I promise they won't do anything bad to you. Likewise, please don't do anything to them. Okay?"

Gin was silent for a long time, and finally nodded: "...Okay."

Koizumi finally breathed a sigh of relief: "Okay, I feel relieved with your promise."

"Next question then."

Koizumi was startled by the sudden murderous intent from Gin, and his mind became much clearer.

"Who was the one who killed you?"

Koizumi: ...

Eh? This is...

She suddenly widened her eyes: "Oh, can I understand that you are concerned about me?"

"... Stop talking nonsense. Who is that person?"

Koizumi narrowed his eyes and smiled a little smugly: "Why, are you going to listen to me this time? It's finally not 'don't tell me' anymore?

"Humph, why don't you continue playing guessing game yourself."

Gin stared at Koizumi expressionlessly for a few seconds, then suddenly sneered and said, "First of all, he is a researcher of the same period as Miyano Atsushi and Miyano Elena..."

Koizumi was stunned for a moment, then immediately became interested.

Does Gin already have the answer in his mind?

And he actually plans to explain his imagination process?

This is so rare!

Speaking of which, she has indeed revealed a lot of information to Gin. Koizumi is really interested in what kind of conclusion Gin can draw from these fragmentary clues.

"...In the photo you asked Sakurai to take and keep on file, there were 11 people, excluding the two from the Miyano family.

"It can be confirmed that the surgeon in the videotape is a man. Eliminate two more options, and there are still nine people left."

Koizumi stared and nodded in support, "Yeah!"

"The data you asked Sakurai to take photos of were from the 'Silver Bullet' project, and the faked videotape was about a soul extraction experiment. This person is related to both projects. So, we can eliminate two more people."

"Mmmmmmm!"

"Of the remaining seven, two have been confirmed to have died many years ago, two emigrated abroad in their early years, and there are three left."

Ha, this really fits in with Detective Conan’s divine law.

The number of suspects is always three!

But at this point, there should be no more way to use the method of elimination.

So next, how do you find the correct answer among these three people?

Koizumi looked at Gin with sparkling eyes and excitement on his face.

Gin:......

I was amused by Melo's expression that he could eat his own melon, and I couldn't help but pull the corner of my mouth.

Seeing that he actually stopped, Koizumi hurriedly asked: "And then?"

Gin continued calmly: "Then I investigated whether the remaining three people had any connection with Sakurai Izumi."

Hearing him say this, Koizumi had already guessed the results of his investigation.

She curled her lips and asked knowingly, "What's the conclusion?"

“No conclusion.”

Koizumi smiled.

Of course, it is impossible to find any results by searching in this way.

Her identity as Izumi Sakurai has never had any intersection with Asakura Mirai, let alone any connection.

Gin: "...So I dug up the two dead old guys and investigated them."

Koizumi was a little surprised, but also a little bit amused.

Are you suspecting that they are faking their death?

Gin, you wouldn't bring people to dig graves, would you?

Gin glanced at Koizumi's expression: "...But judging from your reaction now, we can indeed completely eliminate their suspicion."

Koizumi was stunned for a moment, then slammed the table and stood up: "Cunning! You didn't even investigate those two people, you are just trying to trick me into reacting!

“Humph, but even if you completely rule out the suspicion of these two people, there are still three suspects left.

"So the correct answer hasn't been found yet."

Koizumi curled up the corners of his mouth and tilted his head slightly towards Gin with a smile: "And then? If you can't guess, would you like me to tell you out of kindness?"

"unnecessary."

Koizumi choked.

Gin sneered: "Even if we can't find the answer from the three suspects, we can still start from Sakurai Izumi's interpersonal relationships and work backwards."

Gin paused for a moment before continuing, "Sakurai Izumi's experience before the police academy is simple and too exaggerated to be of reference value. So, let's start with your experience after leaving the police academy."

Gin's words clearly had a hidden meaning.

He deliberately used the name "Sakurai Izumi" at the beginning, and then made a special distinction in the address and changed it to "you" later, obviously in order to verify one of his inferences with Koizumi.

Koizumi understood and nodded with a smile, acknowledging his guess: "Yes, that's right."

It was indeed at that point in time that she became Sakurai Izumi.

Gin narrowed his eyes slightly.

"…since the first time I saw you in the hospital?"

Koizumi smiled and said, "No, it starts with me helping you find Ogura Takuya."

Gin: ...?

Seeing that he obviously had forgotten that little thing and that little person, Koizumi gave him another hint: "Hey, I didn't expect you would actually reward a cat. I still have that milk can!"

Gin: ...!

Koizumi nodded, and added with a smile: "A favor must be repaid. You have a strong principle."

Gin: “…Tsk.”

After getting the answer he wanted, he immediately dropped the subject and returned to his own reasoning.

However, perhaps because of Koizumi's teasing, Gin was in no mood to explain his reasoning process in detail, and simply laid out his conclusion.

“After investigation, it was found that someone in your interpersonal relationship had an intersection with one of them.

"Hey, Shinji Hagiya, after we decided to cooperate with the Americans, your contacts have decreased a lot. What's the reason?"

The corner of Koizumi's eye twitched.

Awesome, he found the clue so quickly.

However, after understanding Gin's work ability, it is not surprising at all that he can achieve this level.

Koizumi smiled and replied, "We have different ideas. He can't stand my collusion with foreign countries."

Gin didn't comment, just sneered.

“You wouldn’t know it if you didn’t check, but this Jingqiu Society’s boss has done a lot of great things.

"Besides, he actually assisted a researcher of the organization to defect. And he succeeded.

“Heh, the person in charge of the Tokyo district at that time was really a waste.

"If it weren't for the serious chaos within the organization at the time, we wouldn't have had time to deal with this old guy, hum...

"After doing something like that, he refused to abandon his family business and run away. Should we say he is courageous or stupid?"

Koizumi smiled and spread his hands: "But he is still alive and well now."

"...If it weren't for him, the intelligence network of the Jingqiu Society would also be very useful to the organization."

Gin turned his head and sneered, "Do I need to tell you the name of the researcher who defected?"

"Asakura Mirai."

Koizumi nodded: "That's right. You're awesome."

She propped her chin up with her hand and tilted her head with a smile: "And then?"

Hearing what Koizumi said, Gin raised the corners of his mouth and smiled confidently: "Then..."
