I'm writing a fictional immortality script in Detective Conan.

"DiDi Di Di Di Di Di Di Di Di!"

Vodka jumped up from his seat, hurriedly wiped the drool from the corner of his mouth, and leaned out of the car window shouting, "Brother! The surveillance ring in Vienna is responding!"

The solitary figure standing under the streetlight in the distance, smoking a cigarette, nodded slightly, indicating that he was aware of the situation.

While Gin was supposed to leisurely stroll over, Vodka quickly turned on the in-car monitor on the passenger side, gasping, "Hiss—"

On the screen, the orange line for "Vienna Beer," which had been unstable since this morning, has plummeted to red. Heart rate, blood pressure, and blood oxygen levels are even below one-third of their normal minimum values! This is an extremely critical situation!

"Phew, thank goodness there was a notification sound. If my brother had found out I'd accidentally fallen asleep after putting down the equipment, I would have been in big trouble!"

"Oh?"

The cold metal ring pressed against his temples, his fingers, which were typing on the keyboard, froze. Vodka swallowed hard, closed his eyes with a look of grim determination, and stammered, "B-Big Brother, I'll never do it again!"

Although Vodka no longer has to worry about dying after drinking the elixir of immortality last year, the lack of a bottom line for life safety means that: before, if he fell asleep, he would be severely punished by his older brother; now, if he falls asleep, he will be severely punished by his older brother!

Especially recently, someone was being reckless late at night. My older brother, who's always grumpy in the morning, was woken up by this and dragged him and his vodka into a life-or-death struggle! He was in so much pain that he had nightmares for several nights!

But...

Thinking of this, Vodka's lips couldn't help but curl into a smile: 'The elixir of immortality! I, Vodka, actually got to drink the organization's top-secret finished product, hehehehehe! Big Brother still cares about me~'

“…” Gin’s index finger, which wasn’t on the trigger, suddenly felt very itchy.

"Vodka."

"Yes!"

After hesitating for a moment between repairing his car and disciplining his subordinate, Gin sneered at his cowardly and foolish grin, put away his pistol, got into the back seat, and said coldly, "Go to Vienna immediately."

"As ordered!"

With his chrysanthemum tucked in, Vodka sat upright in the driver's seat, determined to save his life, and quickly drove towards the coordinates of Vienna—

Meanwhile, at Koizumi Akako's residence.

Kuromon Haruya, in his crow-like form, nailed the haggard-looking, bald-haired Crimson Witch. His initial urge to complain about after-sales service suddenly lessened.

It seems there was a reason for her disappearance, which makes one want to take a picture as a memento—or rather, to understand her situation a little.

Before he could step forward, Koizumi Akako, as if struck by a sudden thought, covered her face in despair and stretched out her large hands: "I know! Don't rush me, I've really reached my limit!"

This is hundreds, even thousands of times more gold than originally planned! If you keep pushing, I'll... I'll take you all down with me!

I focused intently on refining ritual materials during the day! And I focused intently on refining ritual materials at night too!

The magic circle blocking the evil god Lucifer (and incidentally the entire country of Japan) cannot be relaxed. If it weren't for Dracula's substitute, energy potion, Dracula's substitute, home delivery, Dracula's substitute and self-cleaning magic, Koizumi Akako can't imagine what she would be like now.

Even the most legendary witches have never worked this hard in school!

"Does your family practice slavery?" Kuromon Haruya made no attempt to hide his mind-peeping behavior and couldn't help but retort.

Dracula, who had taken over the stirring from the side, seemed quite proud: "Yes! I am the most loyal servant of the Koizumi family."

"The last one who spoke to me was a demon." Kuromon Haruya bristled, shuddering with dread, and asked the crucial question:

"Is the evil god Lucifer so powerful that it requires hundreds or thousands of rituals to isolate him?"

"No, one is enough."

Kuromon Haruya: "Then why did you work overtime to do such a ceremony?"

"...ha?"

The witch, who had been sprawled out on the ground in a "spread-eagle" position, propped herself up, her face practically contorted with confusion: "Didn't you send this here for me to do all of it?"

Kuromon Haruya: "...Is that so?"

Koizumi Hongzi: "......"

Hmm, now that you mention it, it seems we didn't actually ask her to use up all the gold.

That day, after being choked by the great demon, I was so terrified that the gold, once delivered, automatically began working day and night...

At that moment, Koizumi Akako felt like a primary school student who, "because she was too afraid of the teacher, did not hear clearly that the homework was only one page and finished half of the workbook in tears."

"Then why did you send so much? It can't be because you have too much money!"

So much gold, enough to fill the entire basement of the Koizumi family home, is being given away like this. Surely someone will notice something's wrong, right? After all, that's a lot of money!

Looking into his incredulous, watery eyes, Kuromon Haruya tilted his head and asked, "A lot?"

Koizumi Akako: I'm going to explode with you manipulative devils.

"Once you resolve the issue of your subordinates turning into vampires, consider these investments a gift to you."

The Crimson Witch propped herself up on her knees, dusted herself off, pulled a flying broom from the pile of junk, and giggled, covering her mouth.

"Oh ho ho ho! A mere vampire? My servants have been around for hundreds of years, dealing with them is a piece of cake!...So I really don't need to rummage through a whole house of gold, right?"

The crow nodded: "Yes."

Half an hour later, on the plains outside the town of Izumo.

As the figure, completely wrapped in black veil, slowly descended from the sky, Kuromon Haruya blinked and asked, "Akako-sensei, are you changing careers to become an Egyptian mummy?"

Thick black veils almost completely covered her body, revealing only a pair of mischievous, beautiful eyes. Koizumi Akako was almost entirely covered, her snake crown wrapped in layers, leaving only the outline of the golden snake statue, which looked rather grotesque. Her originally revealing Egyptian-style witch costume was further draped over her body; rather than highlighting her figure, Kuromon Haruka felt she resembled a living black mummy.

The vampire butler and the flying broom behind her are just as similar, sharing the same style.

"Hmph, someone as slow-witted as you wouldn't understand." A muffled voice came from under the thick veil. Koizumi Akako pointed to the shrine on the mountainside: "This is Izumo, right under the noses of millions of Japanese gods! I only recently attracted attention because of my summoning, so I have to keep a low profile now."

"But you..." Koizumi Akako circled him, looking him up and down, and stroked her chin. "Strange, did your sect leader help you conceal your aura? Where's your dark energy?"

"I don't know, I don't remember anything," the young man admitted sincerely.

Koizumi Akako nodded understandingly: "Alright, then hurry up. Where are your subordinates? I'm waiting to go back to sleep."

Opening the door, Kuromon Haruya grabbed Asagi Minami by the back of the neck and threw her out. Asagi Minami, who had been wailing and was still unconscious, was thrown out.

"what?"

The moment Dracula saw him, his eyes widened, and the dark red within them brightened considerably:

"Strange. Vampires are corpses driven by blood, so the body that becomes a vampire should have died long ago, but he... although his aura is very weak, he is still a living person!"

Upon hearing this, Kuromon Haruya placed his hand on Asami Narumi's neck and, after a moment, could indeed feel a faint pulse.

"You mean he's still in the process of transforming into a vampire?"

“No, I’m pretty sure he’s a vampire.” Dracula shook his head heavily, staggered forward, and grabbed Asagi’s wrist. “May I taste him?”

Kuromon Haruya cupped his hands in greeting: "Please make yourself at home."

Unlike the two humans, when the elderly vampire approached, Asano Mimi did not show any obvious aggression, and even seemed to back down.

Dracula pinched Chengshi's forearm, brought it to his nose, and sniffed along the skin from his wrist to his elbow, just as one would smell the aroma of fine wine before tasting it.

He loosened his tie, parted his teeth slightly, and then a blood-soaked, ferocious maw opened completely, almost at a 120-degree angle. The sharp teeth, as menacing as a shark's, gleamed in the moonlight. His wrinkled face, along with his features, was squeezed to his hairline; he was definitely not human.

Dracula took a bite, and Kuromon Haruya had no doubt that his two most prominent fangs would pierce through the bone in his hand. Koizumi Akako, standing to the side, turned her back, frowning as she casually surveyed the scenery of the Izumo Mountains, clearly not fond of the sight.

After sucking a few times, the old vampire caught a glimpse of his mistress's back, released his grip, and returned to normal: "Sorry, I was a bit out of line."

Kuromon Haruya leaned against the car, arms crossed: "So, what was the result?"

"The results are somewhat complicated. This young man has indeed been transformed into a vampire, but the concentration is very low, suggesting he is a recent or newly emerged vampire. However, I also detected another aura within him, the aura of your blood, Lord Kuromon."

"My aura?" Kuromon Haruya's first reaction was that it was a blood relationship.

"To be precise, it is the same as yours, an aura of endless life and near immortality."

In other words, the Elixir of Immortality; Yoya Kuromon understood what he meant.

But why did Asami become immortal? He's always been under the organization's supervision. Aside from possibly being with Akai Tsutomu, there's no elixir of immortality outside the organization that I can't perceive. He shouldn't have had any opportunity to come into contact with any related ingredients...

Suddenly, a conjecture emerged from Kuromon Haruya's mind to refute it.

No, Asahi did indeed personally come into contact with a potion that night at the Villa de Seurat. That was the emergency serum "Death in the Afternoon," a diluted and weakened version of the Elixir of Immortality.

"Vampire conversion, also known as the Embrace, requires directly draining a person's blood and then letting them drink your blood, and it's not guaranteed to succeed."

Based on your previous description, he barely meets the requirements for Embrace due to excessive blood loss after the attack and accidentally drinking some of his parents' blood. However, this alone is not enough; he will die from blood loss due to his injuries before being converted.

However, the injection of Afternoon Death forcibly prolonged Asami's life. The factors of the Elixir of Immortality prompted him to repair himself, but the remaining vampire fluid in his body also began to multiply on its own.

“In other words,” Dracula cleared his throat, “he is now considered a hybrid of vampire and you.”
