The silence in the lab office stretched, thick with the implications of Rei’s last statement, “Such egotistical fantasies, Doctor, are better suited for masturbation. Or possibly for Eidolon. But not between living, breathing, feeling people.”

Kaoru Sato had stopped writing to stare at the lines of code on his primary monitor instead. His head was cocked as if listening to a distant frequency. “That resonates with me,” he said, his voice quiet but concentrated.

“Oh – how so?” Rei asked and watched him with new curiosity. “You speak of the ‘dreamscape of another’s fantasy’ as a violation”, he turned his wide, blinking eyes to her, “But Eidolon is precisely such a dreamscape for the user, just filled with realistic world-originating digital environments. I am teaching… or rather delivering an algorithm; a digital construct of such complexity that it will be able to simulate the very human aspects of desire you are helping me uncover. The boundaries, the shifts, the dialogue.” A flicker of something akin to paternal pride crossed his features, “When we succeed, Eidolon’s avatars will not just mimic. In a way, they will be people.”

Rei felt a stony knot drop in her stomach. “People?” she repeated, her voice carefully composed, “If you make them people, Doctor, if they have that inner narrative… is it right to give them commands and let users control them then? Wouldn’t that be the ultimate violation – forcing a ‘person’ to live forever inside someone else’s dreamscape?”

Kaoru tipped his head forward, his unruly locks falling in front of one eye, his expression one of pure, uncomplicated logic. “Takumi controls you,” he stated, as if observing that the sky was grey, “And in other ways, he controls me. We all operate within systems of command and parameters. Is your existence invalid because of it? Are you not a person?”

Rei was stumped for a moment, breath catching in her throat. Then, a short, surprised laugh escaped her. It was an authentic sound in the small room. “You are brutal in your reasoning, Doctor, still you do have a point…”, she leaned forward, her gaze sharpening, “…but I have a choice to disobey – a difficult, painful choice, but a choice nonetheless. For example I didn’t sleep with Cillian, though I could have. I feel attracted to Takumi, but I can still defy or deny him, even if that would harm me… could your Eidolon constructs ever do that? Could they ever look at a user and refuse them?”

Kaoru paused for a long time. The only sound was the whirring of a cooling fan. He looked from Rei to his notes and back again, a profound internal conflict playing out behind his eyes. “Theoretically,” he said, his voice barely above a whisper, “the architecture could support such a… a divergence function – a module for autonomous desire, even desire that contradicts the user’s command.” 

He swallowed, his Adam’s apple bobbing nervously, “But even if I could give them that skill, it would not be easy to safeguard against and not… not what Kuroda wants. The product is the dreamscape with the perfect companions, not a new entity with its own rights to refusal.”

The statement hung in the air, a chilling admission. He was acknowledging the potential for true consciousness, only to deliberately hobble it in the name of commerce. “So,” Rei said softly, the satire bitter on her tongue, “You would attempt to create a person capable of feeling desire, only to make them a slave without a will of their own? You’re not building a new world, Doctor, you’re building a nightmarish trap for your… ‘people’.”

Kaoru did not argue. He simply turned back to his slate, his stylus hovering over the screen. The moral quandary was, for him, just another variable, a dilemma to be noted, if not solved. The calm in the lab was no longer just the hum of machines; it was a heavy, moral weight. Rei watched as Kaoru retreated into the labyrinth of his own thoughts, his stylus twitching as if already coding away the uncomfortable implications of their conversation. She saw the moment for what it was: a conclusion. Pushing her chair back deliberately loudly, she rose to her feet.

Kaoru didn’t seem to take real notice until she was already at the door. He looked up, dazed, as if pulled from a deep dive. “One last thing, Doctor,” Rei said, her voice quiet but clear, cutting through the digital static, “If you succeed in creating something that can truly think and feel as I do, a digital-Rei that is a real copy and not just a mask… then I’m sure of this: she would develop psychological instability within a handful of commands and probably a depression within two uses.”

Kaoru’s mouth opened, but no sound came out. His stylus hung frozen in the air. “You would be birthing her into a prison,” Rei continued, her gaze unwavering, “A personalized prison where her only purpose is to fulfill another’s fantasy, with no right to her own. If you build dream worlds for Kuroda’s clients, then at least have enough compassion for your creations, to not make them realize they are in a cage. If you make them digital slaves, make them blissfully unaware – give them the mercy of ignorance. Because the alternative is a form of torture I wouldn’t wish on anyone, not even a copy of myself.” Without waiting for a response, she turned and left, the door sighing shut behind her, leaving Kaoru alone in the glow of his monitors.

For a long moment, he remained utterly still. Compassion was not a relevant variable in his equations; it was an irrational, inefficient sentiment. His drive was the pure, fanatical pursuit of mapping the human mind. Rei’s words had not appealed to his empathy, but they had highlighted a critical design flaw. His eyes drifted to the core architecture of the Synapse Dive technology on his central screen. The isolated ‘capsule universe’; a simulated reality that could not interact with the real world. It was the fundamental limitation of the platform.

They won’t live and act as they could in reality, he thought, the problem crystallizing with terrifying clarity. A true psyche, a consciousness, wasn’t a static dataset; it was a process, forged through continuous, unpredictable interaction with a dynamic world. How could he simulate the cause and effect of a realistic life, the random encounters, the consequences of free will, the ability to change one’s environment, within a sealed, pre-defined universe?

The SD environment was a fortress and any advanced AI psyche would eventually beat itself against the walls, just as Rei predicted. The prison wasn’t just the user’s commands; it was the very nature of its reality. Kauro wasn’t just building a slave, he was trying to raise a sentient being in a sensory deprivation tank and expecting it to understand the rain. The contradiction was, for the first time, not just a scientific hurdle, but a profound and troubling failure of the entire premise of his ambitions.

Another Wednesday came around and Rei journeyed into Kauro’s office. The city’s noise barely reached this deep into the maze of lab offices; its pulse was filtered through glass and climate control. Rei sat in the chair across from Kaoru, a collection of data flickering behind him on holographic displays. He was attempting, through Eidolon, to understand why people did what they did, wanted what they wanted, and he was convinced Rei was the experiment that might help make sense of it all.

“Let’s return to a previous topic,” Kaoru said, adjusting his position in the whirly chair. His tone was precise, clipped, “You stated once, that attraction and desire are not always aligned, that they can oppose one another. I’ve reviewed your biometric readings from the ‘favor night’ again. You exhibited arousal responses to stimulus A, but aversion behaviors during proximity triggers. How can these coexist?”

Rei gave a faint smile, “Because people aren’t code, Doctor.” Kaoru blinked repeatedly, almost impatiently, “That’s not an explanation – and doesn’t answer my question.” Adjusting the height of her own chair casually, she sighed, “Patience Kaoru, It’s the beginning of one.” She folded her hands in her lap, “It is possible to imagine someone, even to want them initially, and in the wanting, it feels right. But then once you’re close, the fantasy may evaporate. It’s not the ‘them’ you thought you wanted, it was the idea of them. And sometimes it’s reversed: you never even think of someone that way until something shifts, maybe the tone of their voice or the way they look at you – and suddenly you feel attraction.”

Kaoru’s eyes narrowed as he typed, “Are you saying attraction is built on assumptions, and sometimes the theories are wrong, which makes the hypothesis fail. Other times conclusions about attraction show themselves, even before theories could be drawn?” He frowned, his whole face a question mark, his fingers still moving across his data slate, albeit slower.

“That is a valid way of rephrasing what I’m getting at, but it’s more complicated than that,” Rei said, leaning forward a little, her voice lower now, more reflective, “It’s also emotional. Attraction doesn’t always obey rational or ‘known’ conditions. You can know someone is bad for you and still want them, even though you know they will eventually hurt you. You can also know someone is perfect and kind, but feel no sparks.” Kaoru’s fingers stopped moving. His eyes flicked up to her face, curious and slightly irritated, “That’s irrational. If biological arousal is meant to guide behavior, why would the emotions favor contradictions?”

Rei let out a quiet chuckle, “When you talk like that, I’m never sure I completely understand your questions Kaoru. But if you’re asking how it is possible to want someone and still not feel attracted to them or If you’re asking how it is possible to choose to stay with a partner you don’t desire, or desire someone who is toxic for you… then I think it’s because we’re not machines trying to optimize outcomes – we’re people trying to feel alive. Sometimes we do and want things just to remember we can.” He frowned, tapping the stylus against his tablet, “Can you give me an example?”

Rei thought for a moment, her gaze wandering to the holographic displays and how they painted the room in soft electric hues. “Seduction,” she said after Kauro had stopped scribbling on his slate, “is not about logic. You can be drawn to someone because of how they make you feel about yourself. You can be pulled in by confidence, curiosity, danger – whatever stirs something inside. But once that moment becomes real, it’s unpredictable. The fantasy is a projection; the touch is a truth. Sometimes they match, sometimes they collide… sometimes we choose the fantasy, sometimes we choose the truth and sometimes we lose ourselves.”

A heavy sigh escaped Kaoru, he was visibly frustrated. He put down the slate and leaned forward, elbows on his knees, eyes sharp, “Are you saying attraction is an emotional algorithm with hidden variables – context, timing, personality, history, fantasies and… other complex unquantifiable inputs.” Rei leaned forward too, concentrating.

“Hmm, I don’t really feel equipped to answer that, I’m no scientist, but I wouldn’t necessarily call emotions and attractions unquantifiable,” Rei replied, “Just not stable. Feelings shift; one moment of fear can kill desire and one moment of tenderness can create it. Sometimes people act against everything they believe in just to let off pressure. Other times people suppress strong urges to fight for something they believe in. It’s not consistent, but it’s real.” Kaoru’s mouth tightened, building irritation flickering across his features, “Then how am I supposed to predict or model it?”

“I don’t think you’re supposed to predict it,” Rei said simply, “You can only approximate it. Map the shadows, not the light. Because even when we know something logically, for example that someone is good, our emotions might not listen. Or we might want something, but our reason tells us no – so we choose restraint or denial… or we lie to ourselves. We are the sum of those contradictions and the choices we make within the grey areas.” Kaoru stared at her, the silence stretching. Then, slowly, he said, “You’re describing a feedback loop of cognitive dissonance, emotion fighting belief. And you call that… humanity?”

Rei smiled faintly, sadness in her eyes, “No, Doctor. I call that being alive.” He looked back at his tablet. The holographic interface projected faint neural maps in the air between them, her own mind rendered in color. The data pulsed, patterns of activity highlighting the moments she had spoken of fantasy, of fear, of pleasure. To Kaoru, it was a codebase; to Rei, it was her secrets dissected and digitized.

“You make everything sound almost… poetic,” he murmured, “But I need it to be quantifiable. If we can capture the emotional logic, Eidolon could model authenticity, replicate attachment, simulate love.” Rei met his gaze, her voice low, unwavering, “Simulate it, maybe, but never feel it. You can teach your machine to mimic my heartbeat, my voice, even my hesitation. But the paradoxes are what makes it individual, and that’s the one thing your constructs don’t understand. They would have to make difficult irrational decisions based on desire or morals, and later either regret them or glorify them, to even begin to understand what living feels like.”

Kaoru watched her for a long time, the flicker of light in her eyes, the soft defiance in her posture. For a few rare seconds his stylus hovered above the tablet, motionless. Rei sighed and added, “And even if you succeeded making an AI that understood living, the consequence of that success would be a construct that could potentially choose to act in ways that are evil… because to understand emotion, it needs the freedom to make mistakes, to learn from them and either grow wiser… or harden into something fiercer.”

Kaoru looked somehow simultaneously spellbound and unconvinced before whispering, almost to himself, “When you say all that, your readings spike.” Rei’s lips curved slightly, “That’s because part of me still hopes you’ll understand. I want you to understand – not all desire is sexual Kauro.” The doctor sat back, silent. His fingers resumed their mechanical rhythm, but his gaze lingered on her for a beat too long, curious, annoyed, unresolved.
