Transmigrated into Conan, his ability is Rhodes Island

Shiho Miyano, now thirteen years old, was born to parents who were both scientists in the Black Organization. However, they died for unknown reasons shortly after Shiho's birth, and she and her older sister Akemi Miyano were forced to become members of the organization.

She became a key figure in the organization's development program, sent to study in the United States from a young age, given a codename at a young age, and inherited her parents' mantle, at the cost of losing a normal childhood. Her older sister, Akemi Miyano, was used as a bargaining chip to control Shiho Miyano, remaining in Japan to live a normal life. Although constantly monitored by the organization, she had a normal upbringing, normal friends, could attend friends' birthday parties, and climb Japan's highest peak with the mountaineering club…

It would be a lie to say she wasn't envious, but more than envying her sister, Shiho Miyano wished her sister had a better life. A while ago, she received a disk from her sister in the US containing photos of her sister at recent events. Seeing her sister laughing happily with friends in the photos brought a slight smile to Shiho's usually expressionless face. Later, she spoke with her sister on the phone, and her sister told her about interesting things happening around her in Japan, such as a new junior in the mountaineering club who was physically weak and breathless during climbs, but was always the first to run when rescuing someone.

As Shiho Miyano flipped through the photos and listened to her sister's story, it felt as if she were right beside her, experiencing everything together.

Suddenly, the organization informed her that her studies and research could be put on hold, as she needed to return to Japan to carry out a mission. Upon receiving the notification, Shiho Miyano remained outwardly calm, but inwardly she was overjoyed at the prospect of seeing her older sister; after all, she was only thirteen years old at the time.

As soon as she got off the plane, she dragged her luggage to her sister's place in Shizuoka Prefecture. She naturally had a key to the house, and although she had been living abroad for a long time, her sister still gave her the key. Her sister smiled and said it was so Shiho could come home anytime.

But her older sister wasn't home. Shiho Miyano understood; it was a weekday, and her sister had already graduated and was working. She hadn't called beforehand to surprise her. She put her luggage away, walked to the small park downstairs from her apartment building, sat on the swing, and quietly waited for her sister to come home.

I waited and waited, until the shade of the tree that had been covering the swing had turned around, until the sun was gradually setting in the west, but my sister still hadn't returned.

The setting sun mirrored Shiho Miyano's sinking mood. She felt she had been too willful; if she had told her sister sooner, none of this would have happened.

Just then, something furry rubbed against her feet. Shiho Miyano looked down and saw a round, chubby black and white cat making sweet meows and showing her its belly.

Shiho Miyano couldn't help but reach out and rub the fat cat's chin. The cat obliged, letting out a comfortable "meow." Shiho Miyano's gloomy mood improved a little. She reached out and somewhat laboriously picked up the black and white cat, placed it on her lap, and stroked its fur and scratched its belly from time to time.

Suddenly, she heard a noise ahead. Her vigilance, honed by more than a decade of life in the organization, made her look up alertly. A suspicious adult man wearing a hooded black robe appeared on the previously deserted street, holding the hand of a crying little boy.

The little boy looked in her direction, his eyes suddenly widened, he shouted something, and ran towards her, with the man behind him following closely behind.

Having grown up in the Black Organization, Shiho Miyano was practically allergic to the color black. Her eyelids twitched, and she began rapidly considering how to handle the situation… Was this man in black a kidnapper…? The little boy was probably calling for help; should I draw my gun and shoot…? No, ordinary people wouldn't do that. Ordinary people would pick up their phones and call the police…

Thinking of this, she quickly took out her phone. She remembered that the emergency number in Japan was different from that in the United States; it should be 110—but she couldn't remember clearly. This wasn't her fault; she had grown up in a transnational criminal organization, and her upbringing had taught her never to call the police under any circumstances. Her quick reaction was remarkable!

"Hello, there's a weirdo dressed in strange clothes here who seems to be trying to kidnap children..."

Upon hearing this, the man in black stumbled and nearly fell.

After he explained to the little boy, Shiho Miyano learned that he was helping the boy find his cat. She chose to believe the man, for no other reason than that she recognized the face under his hood—it was the same junior in the photo her sister had sent, the one who was physically weak but was the first to rush to the rescue.

Since my sister says he's a good person, I guess we can trust what he says.

They returned the cat to the other person, waved goodbye, and walked away hand in hand. Shiho Miyano had completely composed herself by then; she took out her phone and dialed her sister's number.

"Sister, I'm back."

Akemi Miyano responded excitedly, asking Shiho Miyano where she was so she could come pick her up. Shiho Miyano concealed the fact that she had been waiting for her downstairs at the apartment building for almost a day, only saying that she had just arrived at her sister's house, found that her sister wasn't there, and then called her.

Even through the phone, Akemi Miyano's voice was filled with apology. She said she was taking care of a patient and would be home soon.

Shiho Miyano didn't take her sister's words to heart, assuming that her kind-hearted sister was just helping to take care of her friend again, so she smiled and told her sister to be careful on the road.

The sisters hadn't seen each other for years, yet they seemed to have endless things to talk about. They went out for a meal together, went shopping together, and even when they lay in bed together that night, they were still discussing their experiences over the years that the other didn't know.

However, happy times are always short-lived. A few days later, she was informed that she had to go on a mission. She reluctantly said goodbye to her sister, telling her that she would have some time after finishing her mission and could stay with her sister for a while longer.

The person who came to pick her up was someone Shiho Miyano recognized: Gin, a powerful figure in the organization, and his henchman Vodka.

She cautiously got into the car, remaining silent the entire way and not asking what mission they were going on. Occasionally, she would look up and meet Gin's gaze in the rearview mirror. She bit her lip and lowered her head again.

A member of the organization named Vodka began explaining the mission to her, saying that the experiments she was involved in were related to the development of an elixir of immortality, and that there was a recent rumor in Japan that an elderly woman living on an American island had achieved immortality by eating mermaid flesh. Their mission was to verify the truth of this story and, if necessary, bring back the so-called longevity woman.

Shiho Miyano's lips moved as if she wanted to say something, but in the end she said nothing. She remained silent throughout the journey, both in the car and on the ferry to the American island.

It wasn't until she decided to go somewhere away from those two organization members to get some fresh air that she saw a familiar profile.

"Ah, it's you," she exclaimed softly. She immediately realized the inappropriateness of her actions. If Gin and Vodka, those two ruthless killers, saw her... wouldn't that bring utter disaster to her sister's junior?

She pretended to have mistaken someone for someone else and turned to leave, but as soon as she turned around, she saw Gin and Vodka looking at her from not far away. Just as she was getting nervous, she heard the young man behind her say, "Oh, what a coincidence, you guys are here for the Mermaid Festival too?"

Oh no... wait, did he say "you guys"?

She turned around in surprise and found that the young man was not greeting her. His gaze passed over her and went to Gin, whose face was gradually darkening behind her.

Could it be?! The brilliant scientist's mind raced, deducing a terrifying yet most likely answer.

This junior, whom her sister trusted deeply, was actually a member of the organization sent to monitor her. He had his own agenda when he approached her; the excuse of helping the little boy find his cat was just that… When she looked up again, all that remained in her eyes was cold disgust.

Gin's attitude was even more disgusted than hers, as if he were dealing with an infestation of cockroaches that she couldn't get rid of: "What are you doing here?"

The young man blinked, looking completely innocent. "Didn't I tell you? I'm here for the Mermaid Festival. Did you hear? There's a lottery! The person drawn by the Longevity Granny will receive a Dugong Arrow. Do you know how much that arrow sells for outside? It's an incredibly lucrative business..."

Shiho Miyano sensed that Gin's anger hadn't lessened despite the young man's explanation. If there hadn't been so many people around, she suspected Gin might have pulled out his Beretta and pressed it against the young man's forehead.

“When Bourbon reported on the mission before, he said you refused to write a mission report. Give me a reason,” Gin said coldly.

Akihara looked as if he had suffered a great injustice, his eyes filled with tears as he looked at Gin. "I'm innocent! I've just been too busy lately and wanted to catch up later. I absolutely didn't mean to not write at all. If you don't believe me, just ask Miyano Akemi. I didn't even agree to go out with her..."

As soon as he finished speaking, he felt the young lady beside him cast a death stare at him. He pretended not to notice and continued to look at Gin, waiting for his reply.

Gin glanced at the murderous-looking Shiho Miyano and continued, "What have you been busy with? Your only mission lately has been the Kawasaki gang, hasn't it?"

“Ah, I didn’t say I was busy with a mission.” Akihara smiled brightly. “I’m busy with our research project, antibody immunotherapy and cell research on a certain type of cancer cell. We’ve recently made a huge breakthrough. If nothing unexpected happens, I guarantee you’ll see me on the Nobel Prize in Physiology or Medicine nomination list within fifty years…”

"Bam—"

A loud crash came from one side of the deck, and a flock of startled seabirds flew by, screeching and snarling. People who had come up to get some fresh air on deck craned their necks to see what was happening. Akihara saw this, smiled, waved to them, and mouthed "Unexpected, unexpected."

After doing all that, he nudged Gin, pointing at the still-smoking muzzle of his gun, his tone tinged with concern and worry. "Gin, don't fire your gun carelessly. Even if you're not worried that it will cause your mission to fail, it's not good to scare children or small animals."
