No one understands the laws of Collider better than me.

"Okay, so what is my new identity?"

"A girl who returned from abroad, who had been living overseas all along, her name is Ai Haibara. And my identity is your brother—Osamu Haibara. So don't be so polite when you speak to me. We'll have to work together in the future to try to take down the entire organization as soon as possible."

“Okay, Kitahara—no, brother.”

Hmm, a genius girl is my sister, what kind of toilet paper light novel title is that! But at this stage, the best disguise is naturally that they are siblings, and any other identity would be too incongruous.

"Okay, let's go buy clothes now, Ai."

Shiho Miyano, who was almost seventeen or eighteen years old, now had to quickly adapt to life as Ai Haibara, an elementary school student.

"By the way, this apartment is just a temporary place for you. I will arrange for you to move to a new place after a while."

"No need, I'll stay here, no need to spend money."

"Don't worry, the place I'm taking you won't cost much."

Kitahara Masaki naturally wanted to take her to Professor Agasa's house, which would also make it convenient for Ai Haibara to conduct various experiments and for her to draw blood from Conan.

"Also, the data you sent before is all on that USB drive. You can continue your experiment. Making an antidote for drug A is one thing, but if possible, I'd like you to help me make a nameless poison."

"Nameless poison?"

"That's right, it's a poison like Drug A, but what I want is something to kill people, not some shrinking drug."

What do you want to use it for?

"What to do with it? It's for killing people, of course. What, are you going to use it for charity? But using it to poison the BOSS would definitely be doing charity."

"You...aren't you an undercover agent? Why are you doing this? Won't doing this prevent you from rejoining the police force?"

Ai Haibara couldn't understand what this man was trying to do. Was he going to destroy the organization all by himself? How could that be possible?

"The organization is..."

"What? Even a country can perish. The Black Organization is just a criminal organization. It has become so deeply rooted in the United States only because of vested interests, not because of the threat of force. The FBI and CIA have not put their full strength into dealing with the Black Organization because they are vying for credit and want to keep the organization around for their own benefit."

What's even more ridiculous is that, in order to obtain the name of the rye whiskey, Shuichi Akai eliminated all the undercover agents from the Department of Homeland Security (DHS) who had infiltrated the organization. As a result, the Department of Homeland Security is now completely in the dark about the organization's movements, leaving only the two old-guard intelligence organizations to play a game of fighting each other within the Black Organization.

Therefore, as long as the United States understands that the organization threatens its security, the organization's destruction will naturally follow.

Chapter 70 This is not a phenomenon that can be explained by science.

"What! Kitahara-nii, this little girl is the scientist who created that shrinking drug? How is that possible?!"

"But that's actually the case, and she, like you, became like this because she took those pills."

After helping Ai handle various matters, Kitahara Masaki took her to Professor Agasa's house.

However, this was not the first time Kitahara Masaki had met with Professor Agasa. Before joining the First Investigation Division, Kitahara Masaki had also come here to order some small gadgets.

Professor Agasa also learned through Conan that Kitahara Masaki had long known about the Black Organization and had seen through Conan's identity.

"Then isn't she the inventor of poison? Kitahara-kun, she defected from that organization, is she really credible?"

"Oh my, the great detective doesn't rely on evidence and always acts impulsively, so it's no wonder he ended up like this. If it weren't for your brother, you might have been beaten to death by the organization in some corner."

"What did you say! There's an older brother too? What's going on?"

Kitahara Masaki watched as Conan's face turned red from Ai's spit, but he didn't stop him. Instead, he drank tea and ate snacks with Professor Agasa, discussing a favor he wanted to ask of him.

"Professor Agasa, because of my work, I don't always have time to take care of Ai, so I'd like her to stay with you temporarily, Professor Agasa. What do you think?"

"No problem, I'd love to have you, it's like having another granddaughter."

Neither of them mentioned the money issue. After all, Professor Agasa knew that Kitahara Maki was not a stingy or poor person. In fact, Kitahara Maki was not short of money at all. If he really needed funds, he would just go to a few yakuza to solve the problem. So money was really not an issue.

"Alright, alright, stop being so angry. What's wrong with a grown man suffering a little grievance? It's just being a guinea pig, it's nothing."

"Huh? What guinea pig? Why am I supposed to be wronged?"

"Think about it, you are one of only two individuals who shrunk after taking the A drug, so you are an extremely precious experimental subject. Therefore, the development of the antidote depends on you, Conan."

"Why! Isn't she here? Why isn't she..."

Kitahara Masaki angrily rubbed Conan's head and retorted:

"Why? She's a scientist. If she's not in good health, who will develop an antidote? Can't you, a grown man, take some responsibility? It's settled then. I'll arrange for Ai to attend Teitan Elementary School as well. Remember to get along well with her."

"Do not!!!!"

Seeing Conan on the verge of tears, Kitahara Masaki, who had just played a trick on him, didn't need to think too much at this moment; he could simply enjoy the process.

"Actually, I don't have to move."

“It’s not convenient to continue living in that kind of place. Besides, Professor Agasa has complete experimental equipment here. In order to keep your identity from being exposed, I will let you attend Teitan Elementary School.”

Haibara sighed. As a genius scientist, she naturally wouldn't learn anything if she went back to elementary school. However, it was indeed necessary to conceal her identity. After all, elementary school is considered compulsory education in Japan, and a little girl staying at home all day would only arouse more suspicion.

"Hehe, you might think that going back to elementary school would be boring, but I can assure you that Teitan Elementary School classes are really interesting, especially in Conan's class, where there's a Junior Detective League. Ai, you'll definitely be able to become friends with them."

"The Junior Detective Club?"

"That's right. Spending a lot of time with Conan has gradually caused them to show signs of death, and cases have frequently occurred around them."

This sounds pretty creepy, not funny at all. All three of them except Kitahara Maki thought so.

"Hey, Kitahara-kun, what do you mean? It's all just a coincidence. I'm not some kind of Grim Reaper."

"No, I say you are. From now on, you can change your self-introduction to this—Edogawa Conan, a Grim Reaper. How about that? Isn't it much cooler than a detective?"

"Not at all! Introducing yourself as a detective—that's the coolest thing to do!"

"But you have to understand—Holmes never had a woman by his side. That's the downside of being a detective. You're always on the go, and it's not exactly a proper job. How can women feel at ease with that? So, Conan, do you really want to become a detective like Holmes?"

Be single forever!

"Ahem, in short, as one of the experimental subjects, you must cooperate with Haibara's experiments as much as possible. This is also so that you can turn back into a high school student as soon as possible."

After playing a prank on Conan, Kitahara Masaki took Ai back to pack their things.

The enrollment procedures were completed quickly, and the result was beyond Ai Haibara's expectations. On her very first day of school, she encountered someone who had asked the Junior Detective League to help them. The person said that his brother had gone missing. At first, she thought it was just a simple case of running away from home, but after going to the young client's house, she discovered that his brother was quite a good painter. He could reproduce many famous works like a printer. In fact, one of his paintings, a painting by Natsume Soseki, was exactly the same as the portrait on the 1,000 yen banknote.

"Detective, do you often get cases like this?"

"No, this is the first time we've received a case that might involve counterfeit money."

While Ai Haibara and Conan were discussing the case, Ai suddenly remembered Kitahara Masaki's comments about the kids yesterday. She initially thought it was just a joke, but it turned out to be something else entirely—

She silently took two steps back, her eyes clearly filled with doubt as she looked at Conan.

"Hey! That was just Kitahara Masaki joking! Would you, a scientist, believe such a thing?"

“Great Detective, sometimes when humans encounter inexplicable things, it’s obviously easier to attribute them to divine intervention. I came to elementary school to hide my identity and not cause trouble for Kitahara-nii, and also to make an antidote to help us return to normal. But if you have something unclean on you, then that’s not my responsibility.”

"Aaaaah! What are you talking about, Haibara? There's nothing unclean on me!"

Hearing Conan's feeble explanation, Ai Haibara took two more steps back, called Masaki Kitahara, explained the situation, and Kitahara replied:

"No rush, let Conan continue investigating. Perhaps his physique can attract the suspect. It's still daytime, so as long as he doesn't act impulsively, there shouldn't be any danger. Call me back after his physique has attracted the suspect."

After hanging up the phone, Haibara looked at Conan with a complicated expression. Although she really wanted to dissect him and study him to see how his physique differed from that of an ordinary person, she decided to hold back for the sake of solving the case.

"Brother Kitahara said you can continue your investigation first. At this stage, there is no evidence, and the police cannot be mobilized, so you can continue your investigation until six o'clock."

"Really? That's great! I'll definitely find the culprit before six o'clock this time!"

Chapter 71: It's time to leave a streetlamp for you.

However, to Ai Haibara's surprise, Conan did indeed encounter someone using counterfeit money to buy something at a convenience store before 6 o'clock, but the sample size was too small to be considered conclusive evidence that he was the Grim Reaper.

Then, after Conan shot a locator at the man, he notified Kitahara Masaki.

"Brother Kitahara, what do you think? I could tell at a glance that there was something wrong with that man. He clearly had a thousand-yen bill but didn't go to the vending machine outside to buy cigarettes. He insisted on buying them inside the store. It was obvious that he wanted to use counterfeit money to cheat the clerk and exchange it for change."

"Alright, alright, I'm coming right now. Remember to take Officer Takagi's police car to give your statement."

Ah, taking a statement—it's been a long time since I've done that. Conan is actually starting to look forward to taking a statement, since Kitahara Masaki has been stealing all his cases lately, and it's been a long time since he went to the police station. As a famous detective in Kanto, it seems that only Hattori Heiji still cares about him.

But where did Hattori Heiji go? I remember last time that dark-skinned guy was running around with Kitahara Masaki.

"By the way, Kitahara-kun, where did Hattori Heiji go? Wasn't he doing his internship at your First Investigation Division?"

"Heh, his old man is a shrewd fellow. He saw that I wanted to use the Osaka Metropolitan Police Department's name to handle cases, but after one or two cases, he called Hattori Heiji back."

Upon hearing this reason, Conan couldn't help but sigh that things between adults are truly complicated.

"But isn't all this for solving the case? Why would Hattori's father object?"

“His position can’t allow him to continue supporting his son’s association with people in Tokyo; his roots are in Osaka. Anyway, this is about the competition between the Metropolitan Police Department’s headquarters and branches, and as the Osaka Metropolitan Police Superintendent, he can’t just consider one person.”

What happened next was quite simple. Kitahara Masaki sent his men to track down the suspect who had been fitted with a tracking device. They then found the victim who had been kidnapped to make counterfeit money at their hideout, and arrested several criminals who were making counterfeit money. Just like that, a counterfeit money production den was busted, all because of a group of idle kids who liked to run around.

After all, the amount of money involved was not small, and an innocent citizen was kidnapped, so this was naturally a big case, and all five children needed to be present when giving their statements.

"Hey! Looks like the Junior Detective League has gained another member."

At this time, Kitahara Masaki was still Officer Kitahara, not Haibara Osamu. Logically speaking, this was his first meeting with Haibara Ai. That's why he greeted the children in that way.

"Yes, yes! She's the newest member of our Junior Detective Club!"

"Hello, nice to meet you. I am Ai Haibara."

While Ai Haibara was still internally wondering when she had become a member of the Junior Detective League, Sato led the group of kids to give statements.

“Brother Kitahara, kids these days are really something. When I was their age, I was just thinking about when I could play baseball with my classmates.”

Ah, actually they were just playing a detective game. Although they wanted to do good deeds, the three real elementary school students didn't realize that doing good deeds is not a simple thing.

However, for real children, it's actually a good thing they don't understand.

After finishing taking their statements, Kitahara Masaki took the others to the dessert shop where Amuro Tooru worked, and also took the opportunity to slack off.

"Ah! Kitahara-nii-san, can I really order whatever I want?"

"Of course! I'll take you home after you finish eating, but it's almost dinner time, so everyone should eat less, understand? Especially Genta."

"Hey! Do you have eel rice here?"

"Haha, little ones, this is a dessert shop, we don't sell eel rice, but this plate of daifuku will make you very hungry before dinner."

Looking at the Japanese desserts that Amuro Tooru served, they were exquisite in appearance and tasted comparable to three-Michelin-starred restaurants. Even if he wasn't a policeman, he could still find a job at some famous restaurants.

Kitahara Masaki sipped his drink, wondering how this "King of Part-Time Jobs" had learned so much.
