Refuse to allow Conan to join the main storyline

Perhaps because Koizumi spoke too bluntly, Dr. Tani laughed out loud.

Shinji Hagiya narrowed his eyes slightly: "Way to make money?"

"Yes."

"You and Kamimatsu are familiar with each other?"

"Not too familiar, only met once."

Shinji Hagiya: …

His gaze turned to the cat mound behind him.

"After only meeting you once, he was willing to let Nekozuka find you?"

"This was his idea, and I didn't know about it beforehand."

"So you didn't ask him for the person?"

"Yes."

"What if I say I want to leave the cat grave?"

Before Koizumi could answer, Nekozuka said, "I refuse."

Shinji Hagiya: …

She turned away proudly: "You stole my people and you want me to help you? Humph."

Koizumi: ...

Is this considered a breakdown in the talks?

She tilted her head to look at Shinji Hagiya and then at Doctor Tani. Seeing that neither of them seemed to be planning to talk anymore, she stood up and said, "In that case, I'll take my leave. I'll come back to see you when I have the chance, Doctor Tani."

Doctor Gu did not want to keep her, and waved his hand: "Who wants you to look at me? I wish I could never see you again in my life."

"Then I'll take my leave."

Seeing that Koizumi was not pretending but really stood up to leave, Hagiya Shinji lost his temper, patted the coffee table and raised his voice, "I said, can you leave now? Sit down!"

Koizumi looked down at his annoyed face, and although he didn't know what else to talk about, out of respect for an elder, he sat back down and waited for him to speak.

Shinji Hagiya stared.

"Gu Zhengzhang! Don't you even know how to say a few good words for me?!"

Doctor Gu picked up the teacup with a smile: "Is such a small matter worth getting angry? I want you to see this girl's temper first."

Shinji Hagiya: "That's right! You're so young, but you're even more impatient than me."

He glanced at Koizumi again: "Humph!"

Koizumi then realized that the guy was not rejecting her, but was being tsundere.

...This is kind of cute.

She turned her head and glanced at the man behind her, thought for a moment and asked, "Do you know Mao Zuka?"

Shinji Hagiya snorted again: "Ever since Kamimatsu decided to go to the United States, I asked him for the person several times but was rejected. I saw that he just couldn't bear to let her go and wanted to take her with him. I thought that after he failed, he would take the initiative to send the person to me. After all, there are not many places that can accept cats. I am confident that this is his best choice. But I didn't expect..."

He glared at Koizumi as if this woman hated him for stealing his wife.

Koizumi was a little embarrassed and turned to look at Nekozuka behind him: "Won't you explain it?"

Nekozuka's expression didn't change at all, and he simply said, "I like cats."

Koizumi: ...

Shinji Hagiya frowned: "What does this mean?"

Koizumi coughed awkwardly, "Actually, in addition to the detective agency, I also opened a cat cafe. He probably meant that he liked the atmosphere there."

Nekozuka: “Yes, I like cats.”

Koizumi couldn't help but breathe a sigh of relief.

Shinji Hagiya's eyes widened and he said incredulously, "That's it? Just because of this reason?"

He slammed the table and stood up: "If it's just because you like cats, I can also raise a cat just for you!"

Dr. Gu said leisurely, "You can't. You are allergic to cat hair."

As if to confirm his statement, Shinji Hagiya suddenly sneezed twice in succession.

The scene suddenly became a little awkward.

Doctor Gu tried hard to hold back his laughter and pointed outside to the two people: "Go out and clean the cat hair off your body first."

"……OK."

Koizumi and Nekozuka stood in the corridor using rollers to remove cat hair from their bodies while listening to the sounds coming from the Japanese-style room.

"A-choo! I can't accept this! That was obviously the person I chose first! A-choo!"

Koizumi: ...

When she returned to the room, she saw that Shinji Hagiya had just taken detoxification medicine. His eyes were red and he was sniffing hard, as if he had just cried.

Although he knew it was not what he thought, Koizumi couldn't help but sigh in his heart.

Nekozuka is such a sinful man.

Seeing that Shinji Hagiya didn't want to talk, Dr. Tani said, "Tell us how you and Kamimatsu met."

So Koizumi started by telling them about the chance encounter on the Shinkansen and the whole process of how he and Kamimatsu Hisao met.

Although she never mentioned her purpose of going to see Matsutoshi, the two people opposite her obviously didn't care.

Since he is a colleague of Kamimatsu, Shinji Hagiya must have had dealings with both black and white forces. Even if she didn't say it, this person knows it.

As for Dr. Gu, this insider, there is no need to mention him.

After hearing the twists and turns of the story, Shinji Hagiya gradually calmed down. When Koizumi was drinking water, he sighed, "So you two still have this kind of friendship. My loss is not too embarrassing then."

Then he stared at Koizumi and his eyes became serious: "So what is your purpose in coming to see me?"

Koizumi: "I told you at the beginning, Boss Kamimatsu said you can show me a way to make money."

Shinji Hagiya smacked his lips: "Tsk, this guy always causes trouble for me."

Doctor Gu had been listening quietly, but suddenly he said, "Not necessarily. I think Shangsong has brought you a way to make money."

Shinji Hagiya turned to look at him: "What do you mean?"

Doctor Gu smiled and said, "I should have mentioned to you that I know a little guy with extremely sensitive hearing."

Shinji Hagiya's eyes lit up, and he turned his gaze to Koizumi, looking him up and down: "Is it her?"

"That's right. Your problem might end up on her."

Koizumi couldn't understand what they were saying, so he could only keep smiling and observe the expressions of the two people.

Shinji Hagiya looked very excited: "Then let's give it a try. Little girl, do you mind doing a little experiment first?"

How can anyone want to use me as an experiment...

Koizumi was speechless.

But things had come to this point and it seemed that she could no longer refuse. Although Shinji Hagiya verbally asked for her opinion, he actually ordered someone to get the things without waiting for her reply.

Koizumi looked at Dr. Tani and saw that he looked calm and composed, ignoring the inquiring look Koizumi gave him.

After all, this person is from the red team, so he shouldn’t cheat her, right?

But how could a person from the Red Camp be mixed up with someone like Shinji Hagiya? It seemed that they were very close and could call each other by name.

By the way, Koizumi just learned Dr. Tani's full name, Tani Masaaki.

Whether it is Masaaki Tani, Hisao Kamimatsu, or Shinji Hagiya, they are all characters who have never appeared in the original Detective Conan.

It seems that this third-party force has considerable strength and social influence, and has close ties with both the red and black sides.

What kind of changes will the appearance of these people bring to the direction of the subsequent plot?
