Conan and Gin are both my brothers, what's wrong with meeting them once?

At 3:30 p.m., Kazuma Kudo and Haruka Haibara went out to buy some ingredients for dinner.

When he returned, Shinichi Kudo was still Shinichi Kudo, and he was curiously flipping through a book.

"What are you looking at?" Kazuma Kudo leaned closer and glanced at the cover. "The Tenth Survivor? What kind of book is this? That vampire castle on the cover... it doesn't look like a mystery novel..."

Shinichi Kudo shrugged: "A horror novel, about vampires. Ran found it in the professor's study. Actually, I thought it was a mystery novel, that's why I picked it up to read."

"Never heard of it...who wrote it?"

"Daisuke Torakura wrote horror novels about vampires a few years ago, but recently he has switched to writing superhero novels."

Kazuma Kudo shrugged: "As expected, I've never heard of it before."

I'd rather play on my phone.

Then he received a mission message from Gin.

[Author Daisuke Torakura is blackmailing a doctor affiliated with the organization. This involves organizational secrets; the matter must be resolved within three days.]

Kazuma Kudo: "?"

His gaze fell on the book in Shinichi Kudo's hand.

How did a writer get involved with "extortion"?

They can even extort money from organizations? That's too much like something out of a science fiction novel.

Kazuma Kudo borrowed Professor Agasa's computer to search for information about Daisuke Torakura.

As he was looking at it, a sudden sharp pain shot through his heart, and he instinctively looked up towards the sofa.

Sitting on the sofa, Shinichi Kudo was clutching his shirt tightly to his chest, gritting his teeth and letting out a muffled groan.

"Shinichi!" Ran rushed over to help Shinichi Kudo.

After taking several deep breaths, Shinichi Kudo gritted his teeth and said, "Go...go back inside..."

There are clothes prepared in advance in the guest room where he occasionally stays here.

"At 3:42 PM, 48 hours and 24 minutes after taking the medication, the reaction began..."

Ai Haibara glanced at the time, then scribbled notes into her notebook while asking Kazuma Kudo, who was clutching his chest and carefully taking deep breaths, "Are you alright?"

"...Thankfully, even my brother can handle it..." Kudo Kazuma still had time to let his mind wander. "If I were to consider myself half as Kudo Shinichi, I'd estimate that the level of pain... would be at most half of my brother's. If we're far away, the impact should be even less."

Ai Haibara frowned and looked at Kazuma Kudo for a moment: "Is the connection between twins this strong? Or is this a special condition caused by taking drug A?"

Kudo Kazuma spoke the truth without hesitation: "Perhaps... the situation between my brother and me is special?"

Ai Haibara listened to his seemingly nonsensical explanation and remained silent for a moment: "...I went to your brother's place to time it out."

A short while later, with a piercing scream from Shinichi Kudo, Ai Haibara walked out of his room.

"At 3:45 p.m., the effects of the medication completely disappeared 48 hours and 27 minutes after administration."

A moment later, Ran came out carrying Conan, whose face was still a little pale.

After drawing blood from Conan, Ai Haibara said, "Don't call me when it's time to eat," and then planned to go into the underground research lab.

Unfortunately, he hadn't taken more than a few steps when he was stopped by Kazuma Kudo.

"You invited me to stay for dinner, but you don't plan to eat yourself. Is that reasonable?" he said, ruffling Ai Haibara's soft hair. "The antidote isn't urgent. Go ahead and do your work. I'll call you for dinner later."

Seeing that Ai Haibara frowned slightly, looking like she didn't want to agree, Kazuma Kudo casually pointed at Haruka Haibara: "If you don't eat, then you won't let your sister eat."

Haibara Ai:"……"

She glanced at Kudo Kazuma and said speechlessly, "Go and call me in a bit!"

After dinner, Kazuma Kudo, Ran, and Conan left the Agasa residence.

Considering that Kogoro Mouri was still hungry at home, Kazuma Kudo specially made an extra portion and asked Ran to take it back with him.

The next afternoon, Kogoro Mouri called Kazuma Kudo and said that he wanted to thank him for remembering to cook dinner for him, so he invited him to see the vampire castle.

Half an hour later, sitting in the passenger seat, Kazuma Kudo asked curiously, "Uncle, are there really things like vampire castles in the real world? Did you find vampires?"

Kogoro Mouri coughed loudly: "What nonsense are you talking about? Of course it's not a real vampire's villa."

"Today's client is Daisuke Torakura, a novelist who specializes in vampire-themed works, hence the nickname 'Mr. Decura.' His villa was specially built in the style of a vampire castle and is called Decura Villa."

Kazuma Kudo nodded: "But he's started writing superhero novels in recent years, right?"

"yes……"

After the car rounded the bend, a villa that looked like a vampire castle came into view.

Kudo Kazuma tilted his head. In a castle with such an authentic atmosphere, it would be a shame if someone didn't die.

Upon entering the castle, they were greeted by Toshiya Tadokoro, a student of Daisuke Torakura.

On their way to meet Daisuke Torakura, they also met Daisuke Torakura's wife, Etsuko Torakura, as well as Fumio Doi, the editor-in-chief of the monthly horror magazine, and Hideichi Hamura, a staff member of the Folklore Research Laboratory at Kitakantō University.

While Kogoro Mouri was exchanging pleasantries with Fumio Doi and Shuichi Hamura, Kazuma Kudo was preoccupied with the thought of "the classic three-choice-one-outcome-four-choice-one-outcome," wondering why there was an extra murderer in the pipeline.

Tadokoro Toshiya took Kogoro Mori to the study to see Daisuke Torakura, while Kazuma Kudo and the other two stayed in the reception room.

Watching the light snow outside quickly turn into a blizzard, Kudo Kazuma nudged Conan and whispered, "Look, this villa was perfectly fine before, but as soon as you arrived, it started snowing heavily. I think the snow might even block the roads today, tsk tsk..."

Conan glanced at his bratty younger brother, somewhat speechless: "Don't think I don't know what you're trying to say. Are you going to call me the Grim Reaper again?"

"Is not it?"

The two brothers were teasing each other when they suddenly heard Xiaolan say, "It sounds like there's someone outside!"

The two looked outside together, but saw nothing but a sky full of snow.

Conan turned to Ran and said, "There are no houses around this villa, and with this heavy snow, Ran-neechan, could you be seeing things and mistaking the shadows of the trees for human figures?"

Xiaolan shook her head uncertainly.

Kazuma Kudo shrugged and lowered his voice, saying, "This Daisuke Torakura is just a delusional old man. Since he can build a vampire castle in his villa and wear a vampire suit every day to get into character, who knows if he'll deliberately use some kind of mannequin to pretend to be a ghost?"

"I think it's probably some kind of weird thing that guy was doing, and Xiaolan misunderstood it."

Even so, he knew that Xiaolan was not mistaken.

He received a message from Morofushi Kagemitsu on his Bond.

Zero has received a mission from Rum: to take two snipers to clean up the area near Daisuke Torakura's villa. Specific details of the mission are unknown; be careful.

Since it was Rum who caused the trouble, it's not surprising that Xiaolan, who's incredibly lucky, saw him, right?
