The Phantom Thief of Heart! But Conan.

Tang Ze rescued his hair from the beak of the pigeon above his head and did not respond.

Curacao wasn't discussing anything with him. He probably just wanted to chat about something, or simply wanted to vent his emotions.

Because they have some sympathy for each other and have cooperated with each other before.

"What the doctor just said is correct. I have a brain lesion. This lesion not only affects my memory, but it also affects my emotions and cognition. Generally speaking, people with lesions in this area are prone to memory loss, emotional apathy, and depression. Although I am one of the lucky ones, my luck has always been very small. So, when I started to grow up, these problems became apparent."

Just as her memory not only did not get lost, but after training she gained a memory that seemed like a special ability that normal people did not have, her emotional problems also went to the other extreme.

She couldn't control her mood swings, was sensitive and irritable, easily stimulated by the environment, and had a very poor tolerance for pain. When the organization's excessive training load was placed on her as a child, it easily destroyed her.

"My perception is working, but it's working in the wrong place. The pain of a needle prick can make me scream. I can't stand the stimulation of light, and I can't stand the noise and cold. This makes them very dissatisfied with me..."

"Have you started to be used in some experiments?" Tang Ze interrupted her description and asked after noticing something.

When she said this, Tang Ze vaguely understood where Vermouth's previous words came from.

Considering that Vermouth was most likely not a natural birth, her body was probably very weak at the beginning.

The silver bullet's effect took effect on her, and time began to stagnate in her, eventually forming her current appearance. She looked young and beautiful, but it was like a shell made of wax, shaping her into a solidified statue.

But a shell is just a shell after all. Without the support of medicine, more treatment and follow-up, Vermouth's body will easily collapse.

Tang Ze guessed that this might be the reason why the two of them had an intersection.

"...Yes. As an emotionally unstable sample, I started taking some unverified drugs." Curacao tilted his head, as if deliberately avoiding Tang Ze's sight.

Tang Ze could understand what she was doing. From this symptom, it was not difficult to analyze what she had eaten.

"So, you were one of the first people to take KA, which was developed eight years ago?"

The expression was a question, but his tone was a very affirmative statement.

The KA series was originally a soothing therapeutic drug developed to treat cognitive confusion and emotional instability, and it was probably the beginning of the intersection between the organization and his parents.

There is a world of difference between a researcher who spouts incomprehensible theories and a researcher who comes up with clinically significant medical formulas.

Curacao nodded and did not question why Tang Ze was so sure.

As far as she knows, Kumail, who joined the organization at the same time, may have started taking this medicine at that time.

"Yes. Just like you. It can cure my problem, but it also becomes a new shackle. I should, how..."

He knew that Curacao was hesitating about what to call him - after all, this was the first time she saw Tang Ze in this form.

Tang Ze didn't let her finish the second half of the sentence. He took the initiative to say with a look of consideration: "Just call me Tang Ze now, Miss Sonya."

Curacao was silent for half a second, looking at Tang Ze's profile, with an expression that seemed like pity and a sigh on his face.

Tang Ze accepted her completely misunderstanding gaze without changing his expression. He didn't really want to think about what she was imagining, and he felt deeply in his heart that Haibara Ai's drug development ability was still too advanced.

Just by giving KA a simple antidote, the emotionally indifferent killer became like Vermouth. The effect was surprisingly good.

After finishing his inner thoughts, Curacao nodded and complied with Tang Ze's request: "...Okay, Tang Ze. After starting to take those medicines, I 'got better' and was finally able to be of some use. It was at this time that I accidentally witnessed something I shouldn't have seen."

"Is it related to the experiment?" Tang Ze asked back.

The fact that Curacao was "useful" at that time meant that he might have started to perform some tasks for the organization.

However, considering her age and her unstable physical condition at the time, she was probably just playing the role of a stacker and could not have carried out any major missions. The probability of her witnessing the organization's secrets during the mission was still too low.

So the thing most likely to cause a conflict between her and Vermouth is something related to the experiment.

"Yes. That's what someone least wants to see." Perhaps because they were in a public place, Curacao didn't dare use a particularly pointed name. "That's also a very secret."

"Have you seen experimental data or any research in progress?"

"That's about right. APTX4869, have you heard of it, Tang Ze?"

Conan, who was absent-mindedly holding the glass, heard the term coming from the earplug on the temple of his glasses. His fingertips suddenly lost control of the strength and made a somewhat harsh sound as they scratched the glass.

APTX4869, things have come back to this.

"Well, there's a secret drug that's under development. I have some idea about it."

"That's right, you've seen the information. Did they really pass on the news about this thing? As expected of Tang Ze..."

"Hush, be careful what you say."

When Haibara Ai heard this, she glanced sideways and observed Conan's solemn expression. After confirming that he didn't show any unusual behavior, she withdrew her gaze.

Theoretically, Kumail should not know so much about this drug, but Tang Ze, who has already blown up many research institutes of the organization, has made it completely logically consistent in Curacao.

To Conan, these words would have sounded like a conversation between strangers based on the research of the Karasawa couple. He would never have guessed that in Curacao's eyes, this was actually a confession to one of his own kind...

"That formula is absolutely confidential, but I couldn't control my brain. I just memorized it, and I can't forget it at all. Someone who didn't want to see this was very angry. She said that my restless mind had memorized things that I shouldn't have remembered. If anyone wants to blame someone, blame me for having an illness that I shouldn't have had. Then she planned to execute me for keeping it secret."

Tang Ze listened to Curacao telling him everything as if he was venting, and sorted out the timeline in his mind for a while.

So, this is the real reason for the so-called conflict between Vermouth and Curacao.

After seeing Curacao's appearance changing rapidly due to the experiment, Vermouth must have noticed her talent in cognitive science and knew that she was an excellent experimental subject and would become the kind of material that the organization desired.

She felt uneasy about this, and since such an accident had happened, Vermouth was ready to take the opportunity to kill Curacao.

She didn't want the organization to make any more achievements in this regard, and she also hoped that Curacao would die before becoming that excellent material, so it was not surprising that she took the opportunity to make trouble.

"In the end, I was rescued."

When Curacao said this, his voice was a little dry.

She couldn't help but recall the past and herself at that time.

With her hands and feet tied to the treatment bed, she closed her eyes tightly and kept shaking her head, trying to deny that she saw the equations and text on the screen, but Vermouth obviously had no intention of letting her go.

Just when she thought she was doomed, Rum, who might have been watching through surveillance or other means, stopped Vermouth.

"'Eyes without color', what a perfect blank sheet of paper. I need a blank sheet of paper, I need an eye to see and remember for me. Vermouth, she won't harm the organization. To stain a blank sheet of paper with black is the easiest thing. From today on, you are my 'Curacao'."

Was surviving that day the right choice? Curacao couldn't say for sure.

But Sonya did die that day.

The drugs were administered to her in larger doses and more ruthlessly. After Rum's intervention, even if Tangze Ichikawa wanted to slow down the progress, it would be difficult for him to withstand Rum's pressure.

Just like that, Sonya was erased, her self plunging into silence and darkness.

She completely became Rum's crow, seeing and doing things for him, becoming an extension of his will.

Tang Ze stroked the "black pearl" stuffed in her pocket, thought for a while, and interrupted her state of being immersed in the past.

"Although you were rescued, you seemed very dissatisfied with the result."

"There's nothing wrong with being alive. It's just that it doesn't really count as living. A pathetic person who can't even control his own brain is ridiculous."

"...So, you said you saw the ocean...?"

"Well, that's when they stopped worrying about me losing control. Physically, I could move freely. Just like you now, Tang Ze, I did have some power of action within the limits allowed by the chains."

"You just went to see the sea?"

"No, I didn't have that kind of initiative. I went to kill someone for them. I was at a harbor, chasing down a fleeing target. I shot him, and he fell into the sea."

"That sounds really sad."

"Yeah. When I was a kid, I really imagined what the ocean looked like, but at the time, I only had a simple thought—'If a person's blood fell into it, there would be no color at all. So this is the ocean.'"

As if they were immersed in the situation, the two people on the other end fell silent.

Conan, who was listening, couldn't help but clench the metal badge in his hand and suppress the anger in his heart.

Haibara Ai reached out her hand and patted his shoulder without saying anything.

When the atmosphere on both sides was very heavy, Curacao's low voice sounded again, and it was transmitted intermittently through the microphone into the Ferris wheel cabin, like sobbing.

"Losing my memory and losing control of myself once again is a terrible experience, but being able to let little Sonia 'see the sea for the first time' like today seems not bad at all."

Tang Ze nodded, knowing that this was her complete reflection on her visit to the Toudou Aquarium today. He then gently asked, "I understand what you're saying. To them, you'll just be Sonya, and that's fine."

You should at least tell me your code name. Isn't it inappropriate for me to take the initiative to say this?

"...You're surprisingly gentle in this regard, 'Tangze'." Curacao laughed sarcastically, "'It can only be Sonya'."

She was being sarcastic about Kumail insisting on calling him Tangze.

Tang Ze understood everything, but after pinching the badge, he could only look at him helplessly.

I really want to act out some dark teenage drama for you and sigh with you, but the timing is not right now, so I won’t do that crying route for now, but I’d better give you a few more words of inducement.

"Is that all you want to say? You're in a very dangerous situation now, you know. It would be fine if your memory doesn't recover, but once your memory is fully recovered..."

When Curacao heard this, he obviously understood it as "Is this your last words?"

The organization will not rush to hunt down Curacao if he does not recover his memory. To ordinary people, he is just a mentally ill patient.

But once her memory is restored, she will lose all excuses and it will be impossible for her to return to the organization. To Rum, her behavior is already a defection, and she will never be able to leave the organization. In the world of ordinary people, she is a killer who does not deserve pity.

So she forced a smile and answered sadly.

"I know that once my memory is restored, there will be no reason to let me go. It's the same for everyone. What are you going to do, Tang Ze?"

Tang Ze tilted his head, pushed the pigeon off his shoulder a little, and then flicked his wrist.

The thin butterfly knife slid out of his sleeve and fell into his palm.

"That depends on your choice, Miss Sonia. Do you want to continue being Sonia and never go back..."

Tang Ze controlled his expression and tried to speak naturally, but he couldn't help feeling that his current role was like the wizard handing the dagger to the Little Mermaid.

It's over, he has also been assimilated into the metaphor of the mermaid.

No, if we keep talking like this, the show will run out of steam. Now that it's come to this, why don't you say something?

Looking at the silver handle, Curacao took a breath and finally finished the second half of the sentence.

"...Or, do you want to continue being Curacao?"

On the other end of the speaker, Conan and Haibara Ai raised their heads at the same time, looked at each other, and saw expressions of shock on each other's faces.

"Curaçao," is that Sonya's code name? A citrus-flavored liqueur from the Dutch island of Curaçao?

Colorless and transparent, but can be easily dyed with different ingredients to create a variety of colors of liquor...

Conan looked at the rainbow-like searchlight rising with the water vapor from the fountain, and a complex expression appeared on his face.

Unlike Conan, who began to take a lyrical approach in his heart, the reason why Haibara Ai was shocked was much simpler.

What? Curacao?

Bai was nervous. Tang Ze, you are playing tricks on me again...
