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

"Hurry up and open the warehouse!" Conan urged the old police officer outside the warehouse door.

Just then, Conan seemed to hear sounds coming from the piano room.

"Did you hear anything?" Conan asked the group.

Seeing that no one reacted, Conan ran straight into the room.

Upon entering the room, Conan saw a dark figure standing by the window. As soon as Conan entered, the person broke through the window and escaped!

"Wait a minute!!!" Just as Conan was about to continue the pursuit, he was unexpectedly tripped over a person lying on the ground. "This is... Mr. Murasawa!"

"Ah!!!" Just then, Conan heard Ran screaming from next door and immediately ran over there.

When Conan arrived, he only saw Ran sitting on the ground, terrified, and the body of Mr. Nishimoto, who was already dead.

...Then, after the investigation by Inspector Megure and others who arrived at the scene, and the suicide note hidden in the sheet music on the ground, everyone decided to close the case as a suicide.

However, he was persuaded by Conan with sufficient reasoning and realized that there was another culprit in the case.

After the veteran police officer found Keiji Aso's sheet music, and Conan discovered the hidden compartment under the piano, the case is finally coming to an end.

Just as Conan was about to solve the case by drugging Kogoro Mouri as usual, Asakawa Yu slowly emerged from the darkness.

"It seems you've found the answer, Conan." Asakawa Yu interrupted, looking at Conan's raised arm. However, he didn't use a question; rather, he stated a perfectly ordinary fact.

"Do you remember what I told you, Conan? It seems you still haven't truly understood what I meant."

"Now, it's time to end all this, Uncle Mori. Could you please gather everyone together? I already know who the murderer in this case is," Asakawa Yu said to Mori Kogoro.

"What did you say?! You know who the murderer is? How is that possible..." Mori wanted to say something, but when he saw Asakawa Yu's cold and serious eyes, he realized that the young man in front of him was not as simple as he had imagined.

"I understand," Mori said, and within moments he chose to believe the young man in front of him.

"What did you say?! You know who the murderer is? Okay, now, have everyone assemble in the lobby of the community center."

In no time, everyone had arrived at the community center.

"What the hell! Didn't you say you already knew who the murderer was? Then hurry up and catch him!" Kuroiwa Reiko shouted angrily.

"Please calm down, Ms. Kuroiwa..."

"That's right, I already know the whole truth about this case." The owner of the voice slowly walked out from the stairs, breaking the silence and dissatisfaction of the crowd.

"You are... Mr. Asakawa, right? You said you already know who the murderer is, so what exactly happened?" Inspector Megure asked this question skillfully.

"First of all, I suspect that the person who knocked Mr. Murasawa unconscious in the piano room was you—Mr. Hirata! Am I right?"

"And the evidence is your left hand, the one you injured when you broke the window, am I right? Furthermore, just now, on the way to get the warehouse key with Conan and the old officer, I overheard the officer mention that you and Kawashima always secretly meet at the community center at night. So I suspected you two were doing something shady. Therefore, when no one was around, I went to check the piano room, and sure enough, I found the items you were trading under the piano—some residual heroin powder!!!"

“So, this case is just a dispute arising from the sale of heroin,” Inspector Megure said, looking at Hirata who was kneeling on the ground.

"No, officer, Mr. Hirata actually has nothing to do with these three murder cases!"

"What did you say??? So the murderer is someone else! Then who could it be?"

"Actually, when I learned all this, I felt heartbroken because I could never accept this fact, this heartbreaking, yet equally pitiful... cruel truth!!! Am I right, Asai Narumi, no... I should call you Asai Narumi, right?"

Asakawa Yu's words struck everyone's hearts like a heavy hammer.

"This...this can't be, this can't be real, right, Dr. Narumi?" Ran asked Narumi anxiously.

However, after Asakawa Yu explained the murder method, which was identical to that in the original story, and the reason for the killing, everyone gradually recovered from their shock. However, by the time they came to their senses, Dr. Narumi had already vanished without a trace…

"The killer is missing? What? Go find him right now, quick!!!" Inspector Megure yelled at the officers.

Meanwhile, Conan, who had been silently listening to Asakawa Yu's reasoning, began to feel a sense of admiration for Asakawa Yu and then started to think about where Dr. Narumi might go.

Suddenly, Conan seemed to remember something and rushed towards a certain place.

Only Asakawa Yu remained standing there, gazing into the distance with deep, unfocused eyes, lost in thought...

Hiss! ! !

Inside the house engulfed in flames, Asagi sat alone at the piano, playing "Moonlight Sonata," her father's favorite piece.

“It’s all over, Father.”

"It's not over yet! This isn't over yet. Look, the sheet music your father left behind says: Narumi, you must live well on your own." Conan approached Narumi with the sheet music in his arms.

"It's too late, Conan. It was too late after I started killing people, because my hands are already stained with blood!" After saying that, Narumi picked up Conan and threw him out of the window with a forceful movement.

Bang! The window shattered with a crash. Conan stood up, wanting to rush back in to save the person, but Ran grabbed him.

"You can't go in, Conan."

"Let me go!" Conan shouted as he pulled at me.

Just then, the sound of a piano drifted from inside the house, representing gratitude to Conan and his friends, and also a sense of liberation from their destiny…
