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

As the steam dissipated at their feet, a boy with familiar hair, sleepy eyes, and about seven years old was tugging at Gin's trouser leg, rubbing his eyes with one hand and looking at them with a bewildered and timid expression.

"Big brothers, who are you all?"

"Oh, are you a foreigner...? Hello?"

Gin's pupils trembled: ...

Dracula: "Hmm?"

Koizumi Akako: "Huh?!"

The Little Genius System Noah's Ark hidden in Kuromon Haruya's watch: [Eh?!]

Stared at by Koizumi Akako, the boy blushed slightly, wrapped his barely-covering kimono around himself, and shyly shrank behind Gin's legs.

Beside him, the clothes and equipment that originally belonged to Butbel were loosely piled on the ground, revealing the true identity that no one wanted to accept—Kuromon Haruya.

Koizumi Akako stared at him, her mouth agape in disbelief. She instinctively reached out to grab the small black door, but Gin glared at her and pulled her back.

"Kuromon, this joke isn't funny! Change back right now, or I, Akako-sensei, won't give you the magic you promised to teach you!"

"teacher?"

Upon hearing those two words, Xiao Heimen's face turned deathly pale, and he looked around at the deep mountains and forests, muttering, "Could it be... this is the elementary school!"

Yes, that must be it. Because I didn't want to go to school, my parents left me at a small school deep in the mountains after I fell asleep!

“And you…” Kogoro clenched his fists, his face grim, “you are the teachers at the school…”

"No."

Gin coldly interrupted his speech, gently kicking the small black door further back, and continued to point his gun at Koizumi Akako:

"Teacher Hongzi? You're the one who turned him into this?"

"No way!" Koizumi Akako tossed her long hair aside and said disdainfully to Gin, "This guy brought this on himself. I advise you to put down your gun; mere bullets are useless against me."

"Vodka."

"Brother, I'm here!"

Vodka huffed and puffed as he popped his head out of the back seat, opened the car door, and was carrying two rocket launchers on his shoulder.

Koizumi Akako: ...

Lowering her hand, which had been hesitating about whether to cast a spell in front of the gods, Koizumi Akako turned to the side, revealing the other half of her flawless profile:

"Oh ho ho! As expected of that person, the son of my collaborator, very good, very good, still quite imposing!"

That's right, just to be on the safe side, Kuromon Haruya had instructed her:

'If you happen to run into Gin and still can't beat him, don't bother struggling. Just reveal the organization boss's name for backing you up; at least he won't kill you on the spot.'

Once upon a time, Koizumi Akako scoffed at such claims. Well, now she's just giving Kuromon Haruya face!

As expected, the tall, imposing man in front of her paused, seemingly about to kneel before her, Koizumi Akako, whose power and charm were unmatched.

"Click."

"Eh?"

Koizumi Akako raised both hands together, holding them in front of her eyes, staring blankly at the two silver iron rings stuck on her wrists and the chain between them: "Eh!!"

"Wait, handcuffs?! I'm a distinguished guest of your organization's boss! How dare you treat me so poorly? Aren't you afraid of being eliminated by that man?!"

"Ah."

Not remembering the boss's appearance and features doesn't mean forgetting his consistent character.

Angry? Gin would love for him to have this authoritative style, rather than letting the old school and Rum test him little by little and let their ambition grow wildly.

He narrowed his eyes unhappily, reached behind him and hooked the small black door that was looking around: "Since he is that gentleman's 'distinguished guest,' he should be treated even better."

As soon as the words were spoken, seven black transport vehicles drove up from various intersections in the forest. Several heavily armed men got out of the vehicles and surrounded Koizumi Akako and her servants.

An invitation from an organization is never to be refused.

"... "

"Little crow, why are you crying?"

"No singing." Gin covered Koromon's mouth.

On the other side of the back seat, Xiao Heimen, who was bound with rings, his head between the safety pillows, and his hands and feet restrained by leather straps, nodded obediently for the fifth time, stopping his (what he thought was) heavenly voice.

Then I started humming a song;

"Humph~"

"...Hmph↗Hmph↘Hmph~"

The cold muzzle of the gun pressed against his forehead.

With its neck hunched low and its lips pursed, the little black door turned from a bright future seedling into a wilted flower: "Fine."

Gin felt his finger tremble as he pressed the safety button, and he almost lost control of himself.

Butbel was even more annoying as a child than as an adult!

A surge of inexplicable anger welled up inside Gin, his face sour, and he bit the cigarette butt in his mouth in half—if it weren't for the fact that it concerned that gentleman's A drug, he would have loved to smother the brat to death and turn him back to normal as soon as possible!

Forcing himself to turn away and stop paying attention, Gin took out his phone, his finger pausing for a second as he tapped the messaging app.

The Vienna mutation, the woman who called herself a witch, and Butber who shrank—each of these events would be top secret on its own, let alone all happening in one day.

In the past, Gin would simply report the incident urgently and then wait for the person's reply while smoking, but now...

[Sent: "Izumo Emergency Report"]

Message status: Read

Gin suspected that the man had simply set up an automatic reading system because he never received a reply.

Hey.

A red dot suddenly appeared on the message board, where no response was expected. Gin's pupils contracted, and a glint of light, unnoticed even by himself, shone in his eyes.

[Re: Take it to Tottori headquarters for conservative investigation.]

Kogoro turned his head to the side, staring at Gin, whose face was alternating between dark and light, and was very curious about what was so interesting that had attracted his attention: "Brother Gin, where are my mom and dad?"

"All dead."

Upon hearing this, Vodka, who had been steadily steering the car, involuntarily trembled. After a series of bumps, a sharp scraping sound came from under his feet, most likely because the chassis of the old car had scraped against a stone on a poor country road.

The silence abruptly extinguished the lively atmosphere in the carriage.

Vodka glanced at the rearview mirror. In this suburban area, the dimly lit carriage, unlike usual, lacked even streetlights, and his thin, frail body almost dissolved into the shadows. Only when he calmed down did Vodka belatedly realize that the boy was far less lively and cheerful than he had deliberately portrayed.

Like a stagnant pool of water in a courtyard that never flows, it may appear lively when stirred by external forces, but once it stops and the ripples subside, all that remains when you look down is your own dull and numb reflection in the cold abyss.

“…Oh.” A faint, almost imperceptible voice drifted over.

Xiao Heimen closed his eyes, leaned against the door as if dozing, and murmured calmly in the darkness, "Oh right, why did I forget... I haven't seen my parents for a long time."

Upon arriving at the Tottori headquarters, they found a random room to settle Kokuromon, and there was no further communication between them. Gin was in a hurry to imprison Vienna in the laboratory and didn't have much time to spare. He simply told Kokuromon to "stay put" and turned to leave.

After wandering around the empty lounge for a while, Kogoro lay on the sofa, placed the cushions under his hands, and idly surveyed the monochromatic room layout.

[Hi.]

The screen in the center of the room slowly lit up, displaying a bluish-green circle: [How are you feeling now? Is anything bothering you?]

Noah's Ark, or perhaps an artificial intelligence calling itself Hiroshi Sawada, uses a high-definition camera to observe the micro-expression activities of his facial muscles.

Gin had been staying by the Black Gate's side all along, and his watch had long since fallen off because it was the wrong size. Only now did Noah's Ark have a chance to check on his condition.

"Ah!" The little black door on the seat suddenly jumped up and pointed excitedly: "I know you!"

"You are Q-Baby, a truly human-like intelligent voice that can appear on the Little Q smartwatch! Not 9998, not 998, only 98!"

The rotating rings of Noah's Ark suddenly jammed.

Thinking Project 1: Did this child grow up watching commercials?

Thinking Project 2: Based on the timeline, given how old Koguromon is, did he really have a television when he was a child?

[No, I'm Hiroshi Sawada, your secret partner.]

"A secret partner?" Kuromon pulled a bottle of mineral water from under the table to moisten his throat. "How secret is it that you can't even tell Gin-nii?"

[Yes. I was your most reliable companion before you lost your memory!]

"Memory loss?" Xiao Heimen tilted his head.

Noah's Ark softened the voice of the language module: "[It's memory loss, meaning you've forgotten some things. For example, you only have memories from when you were seven years old or earlier; all your memories after that are gone.]"

"But I don't have amnesia!"

[...]?

Little Blackie squeezed the water bottle, making sure the water level just reached the rim, and played with it intently as he drank.

"Although the body has shrunk, the mind remains agile."

The mysterious little villain—Black Gate—who never lost any memories from the beginning, only had his mind reverted to that of a seven-year-old... well, just Black Gate!
