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

As time passed, the passenger ship finally arrived at everyone's destination.

The group disembarked and set foot on Moonshadow Island.

“Alright, let’s go find the client first. You can look around while I handle the case. As for Mr. Asakawa, you can come with us if you’d like,” said Kogoro Mouri.

Without hesitation, Asakawa chose to act together with the others.

Soon, the group found the island's household registration office.

"Keiji Aso... I can't find this person? That's strange." The staff member looked through the resident register and asked in confusion.

"Please look again carefully, okay? I still have the letters he sent me here!" Kogoro Mouri looked unconvinced.

"This...it's not on the roster. I'm new to this island too, and there are many things I don't know either..." the staff member said, sounding embarrassed.

"What's going on?" a middle-aged man asked as he approached the staff member.

"Ah, Director, it is said that this gentleman came to the island at the request of the islanders. They say his name is Keiji Aso."

"Keiji Aso!!!" the director exclaimed, his face changing drastically. The other islanders nearby also looked surprised when they heard the name and began to whisper among themselves.

"No...it's impossible! Because...because he...died more than ten years ago!" the director said in horror.

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

After the director's introduction, the group realized that this Keiji Aso was a pianist on the island. However, twelve years ago, this pianist suddenly locked himself, his wife, and daughter in their house and set it on fire. He then played "Moonlight Sonata" continuously in the flames until his death.

"Damn it, it's a letter from the dead! What a terrible prank!" Kogoro Mouri said, crumpling the letter into a ball.

“I don’t think so, Mr. Mori. After all, who would be so generous as to spend 50 yen on such a prank?” Asakawa Yu, who knew the plot, offered some opinions to Kogoro Mori.

“Yeah, maybe it’s one of Keiji Aso’s good friends who asked us to investigate Keiji Aso?” Ran chimed in from the side.

"Hmm... what you said makes sense, let's go investigate and take a look."

So the group began searching for the community center.

As they passed by the clinic on the island, they saw a female doctor with delicate features and an intellectual air.

"Hello, excuse me, how do I get to the community center?" Xiaolan called out to the female doctor who was about to return to her clinic.

"The community center? Just turn the corner ahead and walk straight to the end," the female doctor said with a kind smile.

Suddenly, the female doctor's eyes gleamed with a peculiar light, as if she had seen something very special.

"Wait, you're Asakawa, right?? It really is you!!! It's been so long!" The female doctor burst into joy upon seeing Asakawa and grabbed Asakawa Yu's hand to ask.

"You are? Narumi!!! What a coincidence, I didn't expect to run into you here. I heard you went to work somewhere after graduation, so you ended up on this island!"

"What's going on here???" Looking at the unexpected situation in front of them, Kogoro Mouri asked the question that had been bothering them.

"Oh, sorry, sorry! Actually, Asakawa and I were classmates at Beika University. It's just that after graduation, I chose to work on this island, while he chose to open a coffee shop in Tokyo. You see, isn't this island very different from Tokyo? The air is so fresh, and it's so quiet!"

As the female doctor was speaking, a car with its radio on drove towards them.

"Masato Shimizu, please vote for Masato Shimizu!"

The car, with the radio playing, drove past the female doctor who was still in a daze.

The scene was quite awkward at one point...

The female doctor's expression stiffened for a moment before she explained, "However, this was an accident, because the village chief election is about to be held."

So the female doctor began to introduce the candidates for village chief on the island.

Seeing that things were going badly, Kogoro Mori quickly interrupted, "Oh, I'm sorry, miss, we're not very interested in the village chief election on the island."

"I see. Well then, let me introduce myself. My name is Asai Narumi, and I'm a doctor on the island," Asai Narumi said somewhat shyly.

"Well then, Dr. Narumi, we'll take our leave now." Kogoro Mori was in a hurry to get to the community center and didn't exchange any more pleasantries with Asai Narumi before saying goodbye.

“If you go to the community center, you might run into those three people I just mentioned, because there will be a memorial service there tonight to mark the third anniversary of the succession of the former village chief, Mr. Kameyama,” Asai Shigemi said.

After listening and expressing their gratitude, Conan and his friends set off.

"Then, Narumi, let's catch up properly later." With that, Asakawa Yu followed Mori and the others.

Asai Narumi was left alone, gazing at the departing figures of the others, lost in thought.

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

"Honestly, how long are we going to have to wait?!" Kogoro Mouri said impatiently in the community center.

While the group was getting bored, Conan noticed a door. Upon opening it, he saw an old piano inside.

Seeing this, Conan opened the door and went inside.

"No, Conan!" Ran urged from behind.

Upon seeing this, Kogoro Mouri went inside and looked out the window at the vast ocean behind him.

However, just as Conan and Ran were discussing the piano in the room, Mr. Hirata, who had previously entertained them, walked in and shouted in horror, "No... don't touch it! That piano is the one that Mr. Aso played on the day he died!"

"What's wrong with this? What curse? It's just an ordinary piano." Kogoro Mouri asked, puzzled.

Later, after Mr. Hirata's explanation, everyone learned that Mr. Kameyama had also died in the same way, collapsing on the piano, while the same "Moonlight Sonata" was playing nearby.

However, Conan ignored all that and immediately turned on the piano and began to play. Melodies slowly emanated from the piano…
