Conan and Gin are both my brothers, what's wrong with meeting them once?

"Hey, what are you doing?"

Conan gave his bratty younger brother a speechless look: "Hurry up! Honestly, we were already late leaving today, be careful you don't miss the train!"

Kudo Kazuma casually picked up his miniature brother and carried him on his arm like a child, then strode after him.

"Of course, I'm praying that you, the Grim Reaper, won't unleash your fury today and that we don't encounter any murders! Also, it wasn't me who woke up late today, it was your hangover father-in-law!"

"Damn it! Keep your voice down, or Uncle Mori will hear us!"

Conan slapped Kudo Kazuma's arm twice in annoyance: "And what's with this 'Grim Reaper' nonsense! I'm just a detective who gets called upon by cases at any time! Don't you dare slander me!"

After a few steps, Kazuma Kudo, carrying Conan, caught up with Ran, who was at the front, while Kogoro Mouri, who was yawning from a hangover, was left behind and even stopped in front of a train.

Xiaolan urged helplessly, "Dad, hurry up! The train is about to leave!"

Kogoro Mouri pointed to the train beside him: "Then hurry up and get on! Where do you think you're going?"

Ran sighed: "The train you're talking about is the Hana no Machi Line, but we need to take the Yunoyama Line!"

Kogoro Mouri rubbed his forehead, muttering as he followed, "Seriously, what's the difference? We both get off at Hana-no-gai Station and transfer to another train to Tokyo..."

Kudo Kazuma pulled out his train ticket and waved it: "Since I bought a ticket for the Yunoyama Line, let's go!"

At 10:04, they finally managed to get into their seats before the train departed at 10:05.

Kogoro Mouri immediately plopped down in his seat, clutching his head and saying, "I can't take it anymore, I don't want to move, I'm going to sleep for a while..."

Listening to Ran and Conan chatting across from him, and glancing at Uncle Mori with his head covered beside him, Kazuma Kudo yawned, considering whether he should take a nap too. Unfortunately, he was woken up by the two arguing people as soon as he closed his eyes.

He opened his eyes speechlessly and stared at the two people across the train aisle. One of them, wearing a reversible jacket and looking as handsome as Katsuhiko Minagawa, stood up and said, "I can't sit with someone like you anymore. I'm going to sit somewhere else!"

After saying that, he left and went to another carriage.

Ran leaned close to Conan's ear and whispered, "That person looks familiar... Did he stay at the same hotel as us last night?"

Kudo Kazuma nodded in agreement. Indeed, the round-faced man with glasses in front of him had also drunk too much last night and had bumped into Uncle Mori.

Kogoro Mouri peeked out from under the clothes covering him: "Isn't this the group of doctors we met yesterday?"

The round-faced man also noticed them and came over to greet them.

"What happened?" Xiaolan asked with concern. "That doctor seemed really angry..."

The round-faced man chuckled twice: "It's nothing, we just exchanged a few words."

Conan asked curiously, "Where are the other doctors? Why are there only the two of you?"

“We didn’t leave together after the party; some of them took the Hana no Machi Line.”

Seeing that no one was bothering him anymore, Kudo Kazuma closed his eyes and went back to sleep.

After some time, someone gently nudged him: "Ichijin, time to check tickets~"

"Hmm?" Kudo Kazuma recognized Conan's voice. Without even opening his eyes, he casually pulled out a ticket from his pocket and handed it over in a daze.

A little while later, Conan called to him again: "Wake up, get ready to get off the bus."

When Kudo Kazuma woke up, he groggily checked the time.

Eleven o'clock.

Arrived at the station at 11:05.

This train took an hour to travel slowly—so sometimes being slow has its advantages. If this were my previous life, I could have just taken the subway for this short distance and gotten off before I even had a chance to doze off.

However, the train to Tokyo doesn't depart until 11:40, which is truly outrageous inefficiency.

For about half an hour, they could only wait at the station.

Kudo Kazuma found a seat and sat down. He had just taken out his phone to kill some time when he heard someone call out "Sato".

Hmm? Officer Sato? Is there a case?

He straightened up abruptly, only to find that it was the same guy who had argued with the round-faced man with glasses earlier... Well, he had thought he had some other case to pass the time.

"Sato!" The doctor, wearing a reversible coat, seemed to be in a much better mood. "I calmed down a lot when I was looking at the scenery in the carriage ahead. Thinking about it, I shouldn't have been angry with you just now."

"I'll buy you a drink, please forgive me this time, okay?"

The round-faced man with glasses was much happier: "I knew you'd come to your senses..."

The two chatted as they went to the sales area on the platform.

When Kazuma Kudo noticed Conan staring at the two people, he couldn't help but ask him, "What are you looking at?"

Did the Grim Reaper elementary school student foresee the possibility of the case happening?

Conan whispered, "He has a lot of coins in his wallet... Huh!"

He suddenly stepped forward and said to the doctor wearing a reversible coat, "Big brother, your buttons look like they're about to fall off!"

The doctor, wearing a reversible coat, slightly changed his expression and quickly said, "It's alright..."

Even without Conan's prompting, Kudo Kazuma noticed his little action—does a normal person rub their fingers so hard when a button is about to fall off? This looks like he's wiping away fingerprints…

Such suspicious behavior...

Could it be that a spirit has actually arrived?

At that moment, several police officers and security personnel from the station suddenly ran past them.

Where was the body found?

"Inside a Hana-no-Mai Line train that arrived just five minutes ago! The deceased was supposedly a doctor..."

Upon hearing that it might be a doctor or someone they knew, the two arguing duo immediately decided to follow.

Kogoro Mouri, who was still a little groggy from just waking up, suddenly had a sharper look in his eyes.

He straightened his clothes and said, "Okay! Let's go take a look!"

Ran knew Conan would definitely go, but she couldn't help asking, "Dad, aren't you still hungover?"

Kogoro Mouri scoffed, "How could I stand idly by when I hear there's a corpse? The passion of the great detective Kogoro Mouri is enough to wash away the effects of the alcohol!"

The suspicious man wearing a reversible jacket suddenly turned his head and glanced at Kogoro Mouri. In that instant, the emotion in his eyes was far from pleasant.

Kudo Kazuma, who was following behind the group, shrugged.

His behavior is suspicious enough, but he gets nervous just hearing Kogoro Mouri's name. Based on the pattern, this guy is probably the one who provided the soul this time, right?

Upon seeing the body, Kudo Kazuma was completely certain of his guess—the deceased's soul was still trying to harm the doctor wearing the reversible coat. If he wasn't the murderer, then who was?

As for how the murderer killed the victim on the Hana no Machi Line train while on the Yunoyama Line train, that's not important—couldn't the murderer be just as overpowered?
