People in Detective Conan are going crazy over the comments section.

"Mermaid Island? Are you talking about that Mermaid Island with the legend of immortality?"

Upon hearing about Mermaid Island, Akemi Miyano immediately became interested.

“Yes, yes, that’s the place. Hattori-nii said he just happened to have a case related to that place and was thinking of inviting us to go together, so I thought I’d ask Asakawa-nii to come with us. Of course, Ayami-neechan can come too.”

"Eh? That might not be possible, since I just got back to work. It would be a bit..."

Miyano Akemi didn't finish her sentence, but everyone else knew what she meant: she was thinking of taking leave as soon as she got back to work, which was indeed unreasonable for a working person.

But Asakawa Yu didn't think so. He was joking. This shop belonged to him. Whether it was open or not was entirely up to him. Besides, the money he made from opening the shop was not as good as the popularity points he could earn by following Conan and the others.

"It's okay, I don't think you'd mind, right, bro?"

Hattori Heiji said with a grin. He never thought that Asakawa Yu might refuse. After all, this was someone that Kudo Shinichi had strongly insisted on going with, which was enough to show that this person was extraordinary.

"By the way, I'll cover all your travel expenses, so there shouldn't be any problem now, right?"

He truly lives up to his reputation as a rich young master; he can just casually offer to cover such a thing.

However, Asakawa Yu naturally disagreed. "Since things have come to this, it would be unreasonable for us not to go. But we don't need to worry about travel expenses; we're not short of money."

Clearly, Conan and his friend both breathed a sigh of relief after hearing Asakawa Yu agree.

"Then it's settled. Conan will let you know the time. That's all."

After saying that, Heiji Hattori led Conan out of the coffee shop.

"That kid is really energetic and outgoing." Miyano Akemi was a little surprised after meeting Hattori Heiji's carefree personality, because it was different from what she had seen in the newspaper.

"That's normal. Every detective has their own personality."

Asakawa Yu said from the side, "After all, to be honest, the detectives in this world all have some characteristics that are different from ordinary people."

"Haha, what about you, boss? What are your special characteristics?" As soon as she finished speaking, Miyano Akemi turned the topic to Asakawa Yu.

“Me? I’m not a detective,” Asakawa Yu said with a shrug.

"Eh... but I think..."

So, the two of them had a discussion about Asakawa Yu's personality that lasted for half an hour...

Meanwhile, Conan and Hattori were walking back to the Mouri Detective Agency.

"Hey Kudo, why did you insist on inviting that guy along? Even though he knows your true identity, he doesn't seem to see anything special about you."

That's right. The reason Hattori said he would cover Asakawa Yu's and the others' travel expenses was because Conan specifically instructed Hattori before he went to do everything he could to bring Asakawa Yu along. As it turns out, they succeeded.

"Actually, there's something else I haven't told you, something I'm quite reluctant to admit." Conan walked ahead of Hattori with his hands behind his back.

"Oh? What's the matter?"

"Actually, that person's reasoning ability is probably even better than yours or mine."

"What did you say?! How is this possible?"

Sure enough, Hattori Heiji got angry as soon as he finished speaking. You can say that there are things wrong with him, but you absolutely cannot say that his reasoning skills are worse than others!

"I'm not lying to you, Hattori. To be honest, I don't want to admit it myself, but if you've seen that guy's reasoning ability with your own eyes, you might not think that way."

Indeed, Conan really didn't want to admit that Asakawa Yu's reasoning ability was better than his own, but after so many cases, he was now completely convinced.

He admits it, but if you insist that he's inferior to Asakawa Yu, he definitely won't agree. He believes that one day he will become stronger than Asakawa Yu, but for now, he should just honestly and diligently work hard.

"I see... Alright, I've decided. I'll treat this as a contest and see who can uncover the truth behind that letter of commission. If I win, it means that guy isn't all that great after all."

"This also proves that I, Hattori Heiji, am stronger than you, Kudo Shinichi, hahahaha."

And so, Heiji Hattori announced the start of the match on his own, while Conan, who was standing to the side, was speechless at his childish remarks. But he also began to cheer himself up, determined to win the match.

It has to be said that Shinichi Kudo and Heiji Hattori are essentially the same kind of people; otherwise, why would they be able to get along so well?

------------------------------------

A few days later, on the small boat heading to Mermaid Island, Asakawa Hanae stood with Hattori Heiji and the others.

"You brat, you should thank me properly for showing up so abruptly and saying you have a case that requires you to go to Fukui. Just because I came along doesn't mean I don't have anything else to do."

On the deck, Kogoro Mouri, wearing a trench coat and with a cigarette between his fingers, leaned against the outer railing of the ship with a helpless expression.

"But I didn't expect even you, Asakawa, to come." Mori was slightly surprised as he looked at Asakawa Yu standing next to him.

"Actually, Conan came to find me that day specifically to ask me to go to a small island to relax, so I came along."

"Hehehe..." Conan, standing to the side, tried to bluff his way out.

"You won't lose anything, since I'll cover all the travel expenses anyway."

[Holy crap? Osaka Black Chicken, it's you!]

Holy crap, this is an all-star cast! I'd be surprised if a few people didn't die in this episode.

[It seems like this was the first time Hattori and Asakawa appeared together.]

Meanwhile, the three girls were discussing information about their upcoming trip.

"Yes, yes, I just want to stay young and beautiful forever like that immortal old lady, that's why I came along this time. Is Ayami-nee the same?"

It has to be said that the friendship between girls is really peculiar. They've only known each other for less than half an hour, yet they're already this close.

"I see. You're trying to use your youth and beauty to tie Hattori down, right? If it's Ayami-nee, then it should be Asakawa-nii-san."

"Xiaolan!"

On the deck, the girls' laughter echoed continuously...
