Refuse to allow Conan to join the main storyline

"…But I did intend to poison him during the meal."

Seeing that Koizumi's expression became a little scary, Lisa hurriedly explained: "But since I have decided to tell you, I have given up."

She smiled at Koizumi and said, "I think you're right. There's no need to ruin your life for that kind of scum. Thank you, Detective Sakurai."

Koizumi: ...

"In fact, I always thought you looked familiar, but it was only when your companion called out your name that I remembered who you were."

Risa smiled at her and said, "That's why I didn't break free when you held me."

She took a deep breath, a hint of relief in her voice.

"I think this is probably because God can't stand what I've done anymore."

She took out a bottle of eye drops from her bag and handed it to Koizumi: "Since you are a detective, I think it is better for you to handle this."

Koizumi: “…What is this?”

"It's... cyanide."

Koizumi: ...

Sure enough, I guessed it!

So where do you Mihua people buy this stuff wholesale from?

Risa said with a blushing expression: "I originally planned to use this thing to kill Kishida and then frame Aiko. During the meal..."

Koizumi put a hand on his throbbing temple and said, "That's enough. You don't have to tell me the plan. I just want to make sure you really give up the plan to kill people."

"Well, I have indeed given up, please rest assured."

After saying that, Risa hesitated and said, "Detective Sakurai, can you please not call the police?"

Just then, the roller coaster pulled into the station.

Koizumi immediately put the things in his hand into his pocket, turned his head to look at Xiaolan and Sonoko who were waving at him, and whispered: "The crime has been stopped, and Ms. Lisa is not planning to do anything dangerous again. So I have no reason to call the police, right?"

Risa also smiled and waved to her companion: "Well, thank you."

Xiaolan and Sonoko ran over and asked worriedly, "Sakurai-san, does your foot still hurt?"

Kudo Shinichi and Hagiwara Kenji followed the two girls slowly.

Seeing Hagiwara looking at him inquiringly, Koizumi smiled at him with a relaxed expression, indicating that everything was normal.

Koizumi smiled and said to Xiaolan and Sonoko: "Thanks to Miss Risa, everything is fine now."

Xiaolan and Sonoko both breathed a sigh of relief and nodded to Risa: "Thank you, Risa!"

Risa waved her hands hastily: "Ah no, I should be the one thanking Detective Sakurai."

"Eh?"

Both Xiaolan and Sonoko opened their eyes wide in surprise, while Kudo had an expression of "as expected".

"Detective Sakurai?"

As soon as Risa's four companions came over and heard the name, they all looked at Koizumi curiously.

Kako with short hair suddenly exclaimed in surprise: "Oh, yes, it's Detective Sakurai, the one from the Black Cat Detective Agency! I didn't expect to meet a celebrity here, I'm so lucky!"

She exclaimed in surprise: "I really like your cat cafe, the cats are so cute!"

Then she turned to Risa and asked, "But Risa, what did you say was thanks to Detective Sakurai?"

Risa glanced at Aiko and Mr. Kishida, who were clinging to each other again, with contempt: "It was with Detective Sakurai's guidance that I felt I had completely let it go."

Jiazi was immediately surprised and said, "Really? That's great! That's the right way to do it!"

Koizumi also smiled and nodded: "Take a good look around you, maybe Ms. Risa you will soon meet someone who cherishes you more."

Yamaguchi, who had been invisible among the five people, suddenly took a step forward, blushed and said loudly: "Yes, please take a good look at me, Risa! I have liked you for a long time, and I will never let you down!"

"Eh?"

Risa was stunned for a moment, her face suddenly turned red, and she turned away shyly.

The short-haired girl was stunned for a few seconds, then praised Koizumi loudly, "Wow, Detective Sakurai, were you trying to encourage Yamaguchi-kun with that sentence just now? When did you find out? Risa and I didn't notice it at all! You really are a great detective, even better than what is said in the news!"

Koizumi: ...

Ah, actually I didn't mean it.

------

Koizumi gave Risa a coupon for a cat cafe, the kind that can only be used today.

Risa understood what she meant immediately.

"Anyway, apart from the roller coaster, there's nothing else here that interests me. Why don't we leave the amusement park now and go to Detective Sakurai's cat cafe?"

This proposal was unanimously recognized by my colleagues and friends.

The three said goodbye to Koizumi, ignored Aiko and Mr. Kishida, and turned away.

As a result, as soon as they left, Aiko's attitude towards the man next to her immediately became cold.

She withdrew her hand from the man's arm and walked away coldly: "Ah, so boring, I want to go back."

Kishida hurriedly and attentively chased after him.

After watching the five people walk away, Kudo Shinichi suddenly rushed over and reached into Koizumi's pockets.

Koizumi didn't dodge and let him search.

After searching in vain, the little Kudo frowned and asked in confusion, "Where did you hide the things?"

Koizumi looked innocent: "What are you looking for?"

"It's what the auntie gave you when we were on the roller coaster!"

Little Kudo still didn't give up, and fumbled in her pocket again, shouting, "I saw everything just now! You were just pretending that your feet hurt, right? You deliberately kept her away and didn't let her ride the roller coaster!"

"But you obviously didn't pay much attention to that auntie when you were in the queue. She wasn't your goal in coming to the amusement park this time! You two stood there whispering to each other for a long time, and then she took something out of her pocket and handed it to you."

“So you eavesdropped on their conversation while they were waiting in line, and then found out that there was something wrong with that auntie, so you stopped her.

"That auntie was dumped by her boyfriend, so she wants revenge? What exactly did she give you?

"Damn it, I clearly saw you put something in this pocket, why isn't it here!"

Koizumi looked at him with a half-smile: "Is this really what you saw when you were riding the roller coaster?"

"Of course! Where on earth did you hide the things?"

Koizumi turned and looked at Kenji Hagiwara.

Hagiwara was looking at little Kudo with a look of shock on his face.

While waiting in line, he noticed the unusual atmosphere between the two groups of people in front of him, but it was only when a language conflict occurred that he did not continue to pay attention to subsequent developments.

But has little Kudo been paying attention to it?

Then, on the roller coaster that was running at high speed and constantly turning over, even Hagiwara Kenji himself only locked onto Koizumi's position and didn't see clearly what she and the people next to her did.

But this child not only locked onto the target, but also saw the details of their movements, and finally made such a reasonable inference.

This, this child...

He's a good candidate for the police job!
