Refuse to allow Conan to join the main storyline

Koizumi successfully selected a private trainer for himself.

Sato Aiko, 20 years old, is a sophomore at Neon Image Academy. She excels in her studies, has excellent grades, and is gentle and generous, but sometimes a little confused. She is exactly the best candidate that Koizumi is looking for.

At this time, Sato Aiko was sitting on the sofa in the Black Cat Agency, curiously looking at the decorations in the room. She said to Koizumi, who was sitting at the desk and fiddling with her face in front of the mirror, "Ms. Sakurai, is this really your detective agency? How come it looks no different from an ordinary office?"

Unexpectedly, Sato Aiko is actually her little fan!

After learning that his student was actually Sakurai Izumi, the child was very excited and took the initiative to reduce the tuition from 8,000 yen per hour to 5,000 yen. Not only did he teach her wholeheartedly, he also took the initiative to introduce her into his circle of friends.

Koizumi turned away from the mirror briefly. "What did you think it looked like?"

Sato Aiko gestured with her hand: "Just like in the TV series, first there must be a fireplace, next to it is a large sofa, and the coffee table and desk are piled with commissions and newspapers. Oh, and monocles and violins are also indispensable!"

Koizumi smiled and said, "Is there still a Sherlock Holmes missing?"

Sato Aiko nodded vigorously. "Yes, yes, Miss Sakurai, do you like to read detective novels? Do detectives really often encounter danger? What kind of commissions do you take on?"

Koizumi thought about it and told the truth: "Aiko, in reality, the most common commissions for detectives are to find cats and dogs to investigate cheating. Generally, you won't encounter the kind of danger you are talking about."

Sato Aiko's eyes widened in surprise: "Eh, is that so? Miss Sakurai, before you became a detective, you already had great experience investigating bombings and bank robberies. You really were born to do this job!"

Koizumi felt overwhelmed after hearing this.

A person with a personality that involves events is suitable for being a detective? What kind of strange train of thought is this?

She replied helplessly, "It's not that exaggerated! There's no such thing as being born to be a detective. By the way, Aiko, can you just call me by my name instead of using a honorific title?"

"How can that be possible!" Sato Aiko shouted excitedly, "Ms. Sakurai, you are a famous detective, you must be honored!"

Koizumi resisted the urge to smear it on his face. Never mind, let her do whatever she wants.

She put down her lip gloss and looked at her face in the mirror again and again: "Aiko, I think this is about right, what do you think?"

Sato Aiko came over, holding a photo of Kudo Yukiko and comparing it with Koizumi's face, and nodded: "Ms. Sakurai, you are really talented. You have mastered the essentials after only two lessons."

I've only taken the class twice, but I've been practicing almost every day since I got Kidd's tutorial.

I wonder what Kudo Yukiko would think if she knew that I went out with her face on.

If Kudo Shinichi and his three little ones came to the store to play at this time, I wonder if they would be scared.

It seems very interesting, I can try it next time!

Koizumi stood up: "Then I'll go change my clothes, and we'll leave quickly."

"Okay, I can't wait! Those guys don't know that the person I'm bringing is Miss Sakurai, they will definitely be shocked, haha!"

Previously, Sato Aiko showed Koizumi an online campaign launched by a group of her friends who do special effects makeup, called "Want to See You."

Netizens post in a special section of the forum, expressing their wish to meet a certain person.

Aiko Sato and her friends would choose the characters they were interested in from these wish posts and imitate their makeup, then make an appointment with the person who posted the wish to fulfill the other person's wish of "wanting to see you".

After Koizumi expressed his interest in this activity, Sato Aiko immediately decided to introduce Koizumi to her circle of friends.

Today's imitation of Kudo Yukiko's makeup is Koizumi's entry test.

As a popular female star in contemporary Japan, Kudo Yukiko is a name that often appears in wish lists, and everyone in Sato Aiko's circle has imitated her makeup.

Koizumi's first thought after hearing about this was: What if someone uses Kudo Yukiko's face to do bad things?

However, after meeting this group of people, Koizumi found that they were really so naive. They only cared about the similarity of the imitation makeup and discussed how to improve their skills.

Moreover, the profession of detective seems to really have attribute bonuses in this world. Not to mention those who have heard of the name Sakurai Izumi, even those who don’t know her, when they hear that her profession is a detective, they immediately look at her with admiration.

Koizumi, who does not have outstanding social skills, actually thrives in this small circle.

Although the new friends he made were very friendly, Koizumi still felt vaguely uneasy.

In the plot of Detective Conan, this kind of interest group is also where crimes often occur, and it is hard to say that some bizarre murders will not occur.

I hope she is just overthinking it.

In the current timeline, computers are still very expensive luxury goods. But life is incomplete without a computer, so Koizumi spent a lot of money to buy one and put it in the office, and pulled up the network cable.

Looking at a bunch of names with a strong middle school temperament in the forum, such as Phantom Charm, Thousand Faces, Transformation Master, Faceless Man, etc., Koizumi thought for a while and noted his nickname in the name column: Apprentice.

------

Soon a month passed, and Koizumi was obsessed with the research of imitation makeup, but her progress was obvious.

It was only then that Sato Aiko taught her how to make prostheses with silicone, and privately Koizumi had already made the first silicone facial mask.

Although it was still rough, it was the first step in her unscientific disguise.

On the other hand, Koizumi also verified his conjecture. After repairing the body system and upgrading it again, the upper limit of the singularity points that the system can borrow increased from 50 to 80 points.

It is feasible to use injury repair to upgrade the system, but if she is asked to hurt herself, Koizumi cannot bring herself to do such a cruel thing, and can only continue to upgrade the existing props step by step.

She ran back to the police academy to make Black Cat's presence known, informed the five people that she had recovered, and attended the classes that interested her.

The subsequent incidents in the police academy that she remembered still did not happen. The school was peaceful and the organization did not come to trouble her. Koizumi's life during this period was as plain as water, without any waves.

But this peaceful daily life made Koizumi feel a little uneasy. She always felt that she seemed to have overlooked something important.

This sense of crisis is like an undercurrent hidden beneath the water, and she never knows what will happen to her at any time.
