Yes, no one has any further evidence right now, and Black Rock has disappeared without a trace.

Although Nishimoto claimed he was not the murderer, his panicked demeanor made it hard to believe.

Based on current reasoning, the only remaining question is how Nishimoto could have teamed up with Asano Nami.

"Asano's motivation was to avenge his family, while Nishimoto... was driven by guilt?" Kogoro guessed.

"It's not that he fell into ruin and became despondent after Keiji Aso's death. If Aso Nami came to him because of this, asking him to atone for his sins by helping him..."

Recalling Nishimoto's neurotic state, it doesn't seem entirely impossible.

“I wonder if there is such a possibility…” a gentle and pleasant voice said softly, but stopped hesitantly after only saying half of it.

All eyes turned to Akemi, who had spoken, in astonishment.

This girl, who appeared as Yoruichi Toyama's assistant and hadn't shown any outstanding qualities throughout the incident, couldn't help but appear nervous at this moment.

"Mingmei, what are you trying to say?"

Feeling that something was amiss, Yoruichi Toyama, who was still pondering, couldn't help but ask encouragingly.

Anyway, now that everyone's gathered together, it's a brainstorming session without any responsibility, which is much more constructive than some famous detective's monologue.

Yoruichi Toyama admitted that the incident was far beyond what she could reveal, as if everything was shrouded in mystery.

Kogoro and his colleagues' reasoning didn't completely convince him, but his own assumptions weren't enough to clear things up either.

There must be something yet to be discovered and something yet to be thought of.

Under Yoruichi Toyama's persistent questioning, Akemi blinked and finally whispered, "What I mean is, everyone... does anyone here know for sure that Asano Minoru is on the island?"

"Why would we blame everything on a character who never even appeared in the story?"

"Is it possible that someone is impersonating him..."

Before he could finish speaking, Kogoro, Amuro Tooru, Conan, and even Yoruichi Toyama all stared wide-eyed in surprise.

It was as if a door to a new world had been opened.

...

As evening approached, officers dispatched by the Tokyo Metropolitan Police Department arrived at Tsukikage Island.

The team leader was once again everyone's old friend, Inspector Megure.

However, this time, Inspector Megure is still left with an unsolved mystery.

The group of detectives, both experts and junior detectives, discussed the matter for a long time, but ultimately failed to arrive at a definitive answer.

As night fell, the search at sea could not proceed and had to be postponed until the next day.

Inspector Megure personally questioned Nishimoto and Hirata.

When he came out again, his face was quite gloomy.

“They won’t admit anything,” he said to Kogoro and Yoruichi Toyama, who were waiting outside.

This was exactly what the two of them had expected.

"So, where did Nishimoto go during the time he was away from the auditorium? Did he explain it himself?" Yoruichi Toyama asked.

Inspector Megure shook his head unhappily.

He said he was drunk and didn't remember anything.

"Then, what about Hirata?"

"By the way, I remember someone can testify that Hirata also left for a period of time, and he only appeared when we wanted to find Chief Kuroiwa."

At that time, Yoruichi Toyama hadn't even arrived at the event center yet, but Conan and Ran running to knock on the door of the lounge can attest to that.

It was just a few minutes before the music of "Moonlight Sonata" started playing.

"I later saw that tape; it was a copy, with a deliberate five-minute gap at the beginning."

In other words, it was enough for "someone" to arrange Kawashima's body, press the recorder to play the music, and then leisurely appear in front of everyone, listen to the music together, and then rush to the scene.

"You're saying it's highly likely that Hirata and Nishimoto conspired to kill Kawashima?" Inspector Megure had roughly pieced together the sequence of events.

“It’s very likely that Chief Kuroiwa will also be involved…” Yoruichi Toyama added.

Just as Akemi said, in this series of actions, they all had the shadow of "Asano Minoru" in their hearts, so they naturally attributed everything to Asano Minoru's revenge.

But no one actually saw Asagi in person.

Perhaps, the claim that "Ma Shengshi" is just a trick to deceive people.

Yoruichi Toyama, who had always been in control of the plot and determined to prevent the murder, realized that this was probably the biggest failure she had to face since her transmigration.
