No one understands the laws of Collider better than me.

Matsumoto Kiyonaga had assumed that Kitahara Masaki, the young man who had returned from abroad, would participate in various variety shows after becoming famous, or at least become more flamboyant in his behavior. However, after becoming a celebrity, he remained dedicated to his work in the First Investigation Division, and even when he was slacking off, he was no different from those old hands.

Strange but talented—that's basically how the police leadership described Kitahara Masaki.

Little did they know that Kitahara Masaki's dedication to solving the case was merely a means to better carry out his undercover work. By uncovering the truth about both sides as soon as possible, he could naturally command higher prices.

His reluctance to appear in the media is simply a matter of personality. If his every move were known to the world, what difference would he make from a monkey in a zoo?

After watching the video, Kitahara Maki had no idea what his boss was thinking. He just thought that when the new character appeared, his achievement system would probably have a few more corresponding achievements.

"Ah, the appearance of a new character means someone is going to send it, doesn't it? Hattori Heiji, you've committed a heinous crime."

Heiji Hattori, who hadn't even appeared yet, sneezed and muttered:

"Shinichi Kudo, Masaki Kitahara, hehe, let the famous detectives and police officers of Kanto compete with me, Heiji Hattori, the famous detective of Kansai."

After saying that, he took out a bottle of strong liquor from his backpack. Thinking that he had just sneezed, he wondered if he should have a drink first.

"Never mind, this is a gift I prepared for visiting the Mori Detective Agency. I heard that Uncle Mori likes to drink, so this bottle of strong liquor that I specially bought from China should be able to get him to tell me where Shinichi Kudo went."

Knock knock knock. With that thought, Hattori Heiji put the sake back in his backpack and knocked on the door in front of him.

Next, while Hattori Heiji was showing off his deductive skills, he was careless in his daily life, giving Conan, who had a cold, a sip of strong liquor. Meanwhile, a middle-aged woman arrived at the Mouri Detective Agency, requesting that Kogoro Mouri conduct a character investigation on her son's girlfriend.

"My name is Kimie Tsujimura. I hope you can conduct a character investigation on this girl."

"Hmm, let me take a look at her resume first—um, her name is Katsuragi Sachiko, she's 24 years old, graduated first in her class in both high school and university, and her current dream is to become a female doctor dedicated to healing the sick. Is there a problem with that?"

Uncle Mori asked.

Before Tsujimura Kimie could answer, Hattori Heiji, reclining on a chair to the side, said:

"It's just because she's too perfect that I can't stand her. Humans are such suspicious and jealous creatures. When we see someone who is too perfect, we can't help but want to find fault with them."

The middle-aged woman, who had been mocked, glared angrily and asked:

Who is this rude brat?

"Hmph, I am Hattori Heiji, the high school detective from Osaka. Since you're investigating your family, why don't you let me and Uncle Mori go together? That way, to outsiders, it'll look like a father and son visiting your husband."

Thinking of this, Hattori Heiji seemed to remember something and turned to Ran, saying:

"You should come along too."

"why?"

"If you go, Kudo might come too."

Upon hearing this, Ran and Conan naturally went over as well, and the entire Death Team visited the diplomat's house.

In the world of Detective Conan, something unexpected is bound to happen.

After finishing lunch, Kitahara Maki received a call from Inspector Megure, saying that someone else had been murdered, and this time it was a diplomat.

"Hey, isn't there a high school detective named Hattori Heiji at the scene?"

"Yes, Brother Kitahara, is it possible to deduce this from something like that?"

Kitahara Masaki chuckled, offering no direct answer, only saying that he would arrive soon.

Upon arriving at the scene, they found a portly man lying there. Before Kitahara Masaki could even ask about the victim's condition, Takagi had already cleverly begun to preemptively answer questions:

"The deceased's name is Tatsumura Isao, 54 years old. A poisoned needle was found at the scene, and the victim's lips were purple, with needle marks also found near his ear. Therefore, the preliminary investigation of the scene suggests that it was a poisoning case."

Poisoning case? Why not just start by investigating the source of the poison?

Oh right, the deceased was a diplomat, so this case is probably one that can't be delayed.

I'm so tired, every single day.

"Oh! You must be the police officer who defeated Shinichi Kudo—Masaki Kitahara, right? I am..."

Kitahara Masaki hadn't taken two steps when Hattori Heiji grabbed him and eagerly introduced himself. This Osaka black chicken (a nickname for Kitahara Masaki) seemed excited, probably having met a worthy opponent.

But for Kitahara Masaki, these high school detectives were the reason he had to work overtime.

"Alright, alright, the police here probably all know you."

"Hmm—does that mean my reputation as Hattori Heiji has already spread throughout the Kanto region?"

"It's because your father is the head of the Osaka Prefectural Police Headquarters."

Uh……

Hattori Heiji, who had been silenced, finally stepped aside, allowing Kitahara Masaki to walk to the body.

An infrared thermometer was used to check the body, and it was found that it was still warm.

If the time of death was less than half an hour, then it was probably another crime committed by a family member.

but……

Kitahara Masaki looked around and, excluding the Death God Team, there were still four people left.

“Inspector Megure, we need to ask these four what they did an hour ago.”

"What! Brother Kitahara, do you mean this is a murder case involving family members?"

"I'm sure the murderer is among these four people."

The deceased's son and daughter-in-law, the deceased's father, and the deceased's wife.

“Um, Brother Kitahara, there’s actually another person, the housekeeper.”

"The murderer must be one of the five of them."

Five choices? This is so troublesome. Let's just have an open-book exam.

Kitahara Masaki took out a gadget from the system's four-dimensional pocket, and it seemed to transform into a round-faced big cat that loved to eat dorayaki and had no fingers.

Chapter 21 Kudo, you have three minutes left.

[The Savior of the Japanese Police]: Successfully helped the Japanese police solve ten cases.

Reward item: Holmes' magnifying glass.

I only recently completed this achievement, unlocked right after beating up that serial thief. And the item rewarded by the achievement just happens to help solve the case.

After picking up the magnifying glass, it seems that only crucial evidence will be displayed. This marker can be located up to five meters away, but only one piece of evidence is displayed in each case.

This isn't a magnifying glass, it's more like an X-ray machine. I can only say that I, Kitahara Masaki, didn't use any cheat codes; the evidence just happened to heed my call.

One bright spot was found in the deceased's wife's pocket.

Seeing this, Kitahara Masaki could no longer fail to understand that this seemingly grief-stricken aunt was the real murderer.

"By the way, Inspector Megure, have someone search you too, and carefully check your belongings to see if you have any containers that could be used to carry poison needles."

As expected, the deceased's wife, Kimie Tsujimura, began to shout:

"What! Are you police suspecting us? How could we possibly kill our own family members?"

Kitahara Masaki chuckled, and just as he was about to retort, the little brat next to him suddenly let out a groan and collapsed to the ground.

"Conan!"

Upon seeing the kid suddenly fall ill, Kitahara Masaki suddenly remembered the plot—Among the gifts Hattori Heiji brought from Kansai, there seemed to be a large-body-enlarging baijiu (a type of Chinese liquor), so it seemed this guy was going to get a trial card for his original body.

Ran was about to help Conan up when Kitahara Masaki stopped her. Kitahara Masaki simply picked up the kid and said to Inspector Megure:

"Inspector Megure, I'll go take the kid to see a doctor first. Just do as I say, and it'll be basically over."

Without giving anyone a chance to object, they went directly to a house at the end of the street with Conan, locked the door, and started recording.

"Hiss—Brother Kitahara, do you know something?"

Seeing Kitahara Masaki act so decisively, a glimmer of hope rose in Conan's heart.

"I don't know much, but the drug that shrunk your body was a new type of poison developed by the organization. I've never encountered a case like yours where your body shrank but you're still alive. But judging from your current condition, I guess your body is about to undergo some changes again."

"Oh, I see. Oh, and Kitahara-nii, could we please not record this?"

Kitahara Masaki patted Conan's face and laughed:

"No."

dong dong dong.

Xiaolan knocked on the door, and the kind-hearted girl asked worriedly:

"Mr. Kitahara, is Conan alright?"

"Don't worry, it's just a high fever that's common in children. They'll be fine after a good night's sleep."

Soon, under the influence of the strong liquor, Conan's body gradually returned to normal, and then came the moment of transformation where he tore apart the law of conservation of energy with his bare hands and stepped on biochemistry with his feet.

"Some girls must really want this kind of transformation. Hmm, maybe some guys want it too."

Shinichi Kudo was overjoyed to be restored to his original state. He wanted to get up and take a few steps, but because the transformation consumed too much energy, he started panting the moment he stood up.

"Kudo, have you ever watched Ultraman?"

ha!?

For a moment, Shinichi Kudo was stunned and stood there. Then, after thinking about the characteristics of Ultraman's transformation, his face, which had been flushed with excitement, turned deathly pale.

"Kitahara-nii, will I turn back into my original form later?"

"Yeah, and it's better if you change back. If someone sees you and the Black Organization finds out..."

"Ok."

Having already been taught a lesson by Kitahara Masaki, Conan has learned his lesson and no longer rushes out to begin his deductions.

As Kitahara Masaki wondered what Miyano Shiho's expression would be after seeing the video, Inspector Megure suddenly called, urgently shouting:

“Brother Kitahara, that detective from Kansai found evidence in the Japanese-style room, and he also cracked the locked-room mystery! Ah, even the murderer has confessed, so we don’t need to search him anymore. The murderer is that old gentleman, the victim’s father.”

ha?

I've already told you the general steps and solutions to the problem, but you insisted on taking a different approach and ended up getting the answer wrong. What can I say about that?

"Inspector Megure, wait a minute, don't jump to conclusions so quickly, I'm coming right now."

Kitahara Masaki put away his cell phone, looking utterly exhausted, and instructed Kudo Shinichi:

"You stay here until you recover before going out."
