No One Survived?

"It seems these must be the codes."

Fujino picked up the piece of paper and glanced at it. "Judging from the age, it's very old, at least forty years old. Moreover, the words on it should be printed with steel plates. This kind of printing technology must be from a long time ago. It seems that the guy who invited us over was lying, and the so-called auction should also be fake."

Mōgi Harushi, standing to the side, shook his head. "It seems that guy wants us to decipher the cipher on this."

Conan nodded in agreement, then looked down as if he had discovered something else. "Hey, didn't you guys notice? This piano looks wet! And there's that lady's Luminol reagent underneath."

"So, they must have been here before."

Mōgi Harushi suddenly remembered something and shouted, "Hey, mustache, go turn off the lights!"

"Oh!!"

Kuroba Kaito pretended to be taken aback for a moment, then quickly turned off the light.

Then, a message written in blood appeared before everyone's eyes, "I too will be killed by Karasuma Renya, but before that, I have already grasped the final trump card to decipher the code..."

"The last trump card?!"

The group of people were slightly taken aback.

Meanwhile, in the restroom not far away...

"Miss Gunda?"

Ran emerged from the restroom stall, glanced curiously at Tsukida Ikumi, then looked around and asked curiously, "Where's Ms. Ishihara?"

"She should be in the hallway."

Tsukida Ikumi stood in front of the sink, washing off the anesthetic from her hands, and answered.

"Corridor?"

Ran asked in confusion.

This wasn't part of Fujino- Senior's plan...

Just as she reached the corridor, she suddenly discovered that the maid had collapsed at the bathroom door.

"Ms. Ishihara?! This..."

Ran was taken aback and exclaimed in surprise.

This wasn't in her script at all.

At that moment, Tsukida Ikumi suddenly appeared behind Ran, took out a handkerchief and covered her face.

A short while later, Ran fainted.

Tsukida Ikumi used a handkerchief to smother Ran until she was unconscious, then dragged the two of them into a bathroom stall and pretended to suffocate them.

She put away her handkerchief, washed her hands, and came out of the bathroom. With her arms crossed over her evening gown, she couldn't help but think to herself, "Hmph... I didn't expect that guy to worry that the two girls' acting wasn't realistic enough, so he actually pulled off this spy-within-a-spy act."

"It really was you!"

Tsukida Ikumi turned around and saw Hakuba Saguru, as expected, emerge from behind her, holding a pistol. He began his deduction. "There's a bomb in the car, so the culprit wouldn't risk his life to go with us. That leaves Ran, you, and either Fujino or Ishihara... Now it seems the culprit is you, right?"

Tsukida Ikumi glanced at him out of the corner of her eye, her tone slightly seductive. "Oh dear, young detective, that thing you're holding is quite dangerous, you know. I can't understand a word you're saying."

"Stop pretending..."

Hakuba Saguru's eyes narrowed slightly. "This gun was under my pillow. Are you planning to frame me as the mastermind behind this?"

"What a coincidence..."

Tsukida Ikumi smiled, slowly turned around, revealed the pistol hidden in her palm, and swiftly fired a shot at Hakuba Saguru's chest.

"Bang!"

With a gunshot, Hakuba Saguru fell to the ground.

"Hehehe, it seems we have the same idea. What a pity..."

Tsukida Ikumi smiled, turned around, and quickly fled towards the central clock tower.

Immediately, Fujino and his group arrived quickly from the other side.

Fujino rushed forward and picked up Hakuba Saguru, who was already dead and whose mouth was still gushing blood. He looked him over, his expression showing some sadness, and even a tear glistened in the corner of his eye. "Old Horse! Oh, Old Horse! Damn it! That woman!"

Mori Kogoro, Kuroba Kaito, glanced at Fujino, who looked as if he had lost a close relative, and couldn't help but twitch his lips.

Is this guy's acting always this good?

He was speechless for a moment, but continued walking according to the script. As if he heard a noise, he immediately rushed up. "Who's on the stairs!"

"Stop pretending."

After Mori Kogoro left, Mōgi Harushi, who had come with him, suddenly pulled out a pistol from his pocket and pointed it at Fujino: "I'm afraid this was all planned in advance, wasn't it? I felt something was wrong as soon as I arrived here. You know Hakuba Saguru Mori Kogoro... Now, the only ones who have been murdered are outsiders. Obviously, the murderers are you guys!"

As he spoke, he looked at Hakuba Saguru, "This kid must be the one you sent to kill that woman, Yata. And Mori Kogoro must have gone after Yata, right?"

"Hmph, trying to turn the tables on me?"

Fujino narrowed his eyes and looked at Mōgi Harushi: "You have a gun. If you ask me, you're in cahoots with Gunda and you'll frame us for all the crimes in the end."

"Still being stubborn even when death is imminent!"

Mōgi Harushi shook his head, his tone somewhat contemptuous. "Even if it's not what I think, you're definitely the murderer, or someone who's been spying on the so-called treasure and the way out of here. If you ask me, you're absolutely Kaito Kid in disguise!"

"Then why don't you give it a try!"

Fujino suddenly sprang up and pulled a Wooden Sword from his suit jacket.

"It's that kind of magic trick again!"

Mōgi Harushi clicked his tongue and fired several shots, but Fujino skillfully dodged them all.

"What?!"

Just as he was wondering what was going on, Fujino seized the opportunity, picked up Wooden Sword, and smashed it hard at Mōgi Harushi's head.

"Bang!"

With a muffled thud, Mōgi Harushi collapsed unconscious.

Fujino clutched his arm; it appeared that some blood was flowing out.

"Bang!"

Just then, another gunshot rang out from upstairs.

"Those two despicable bastards..."

Fujino stood up, picked up Mōgi Harushi's gun, fired a shot at him, and then picked up his Wooden Sword and chased after him.

"Kata!"

Tsukida Ikumi raised her pistol, pointing the muzzle at Fujino who had just entered. "It seems that now it's just the two of us left."

"Yes, your accomplice is dead."

Fujino also gripped the Wooden Sword tightly in one hand and held a pistol in the other.

"It's no use saying anything now..."

Tsukida Ikumi's expression remained unchanged. "It seems that only one of us can survive. I'm very curious about what kind of treasure it is that could cause us to kill each other."

"Hehe..."

Fujino sneered, "I was actually looking forward to working with a beautiful and wealthy woman like you, what a pity."

"Snort..."

Tsukida Ikumi also said meaningfully, "What a pity."

"Bang!"

"Bang!"

Two gunshots rang out, and blood gushed from the two men.

They fell to the ground almost simultaneously, and none survived.

Meanwhile, inside the secret chamber of the Twilight Manor.

Chizen Kōdai stared blankly at the scene of mutual slaughter on the monitor screen.

Coming to her senses, she took a deep breath and gave a cold, mocking laugh, "Even with these detectives, the mystery still can't be solved..."

To be honest, the fact that these detectives suddenly started killing each other was something she hadn't expected. However, she wasn't surprised, since the initial plan was for these detectives to kill each other.

She just didn't expect that Oogami Shuku Zen's hasty plan would actually succeed.
