At the moment Agnes Tachyon announced, "The experiment begins", the atmosphere of the entire dormitory changed.
"Directive confirmed, environmental module activated" she whispered into a communicator on her wrist.
The next second, the tense red laser grid in the room disappeared and was replaced by a soft and extremely ambiguous pink light pouring from the ceiling.
At the same time, sub-audible music, which Kaito had never heard before, silent yet resonant in his heart, began to play from hidden speakers.
He felt his blood flow accelerate.
"This is the 'Hormonal Resonance Overture' that I modulated based on the frequency of your pheromones; in theory, it can maximize the coupling efficiency of our bio-fields"
Agnes Tachyon explained with a terrifyingly calm tone, almost like an announcer, narrating data into his ear non-stop while kissing him.
Kaito felt completely controlled. He was no longer an individual, but the central and crucial part of this insane "experiment".
"Your heart rate has risen to 135 beats per minute, an excellent value; your systolic blood pressure is 140, and your unique pheromone concentration, the diastolic pressure, has reached an unprecedented peak..."
Her kisses became deeper and more fervent, yet her words remained as calm as if she were reading a thesis.
"Data... Perfect! Your body is sending me the most intense invitation signal!"
She looked at Kaito's face, flushed with passion, as if admiring a masterpiece she had created herself.
"Damn it..."
Kaito felt provoked by her attitude, which treated him entirely as an "experimental subject".
No! He couldn't let her lead him by the hand anymore! He had to regain the initiative!
With a sudden burst of strength, he flipped over, trying to pin the mad scientist beneath him, to let her taste what it was like to be "investigated".
However, Agnes Tachyon, trapped beneath him, didn't show the slightest hint of panic.
Instead, she revealed an even more excited and fervent smile than before.
"Oh, my God? Such amazing data! Is experimental subject A actually trying to control variables in reverse?"
Far from resisting, she extended her arms, actively and firmly wrapping them around Kaito's neck, with her legs also entwining him.
"Excellent! Very well! This unexpected situation will make our experimental data more valuable and diverse! Come, let me see how far you, as a 'miracle', can take this experiment to a marvelous climax!"
She wasn't afraid; in fact, she was even more expectant!
Kaito felt as if he were hitting cotton; all his initiative was turning into cooperation with her experiment.
"To make our 'fusion' more complete, I have prepared some small 'catalysts'"
Agnes Tachyon smiled mischievously, pulling out several small test tubes of different colors.
She uncapped them and applied the liquids they contained to herself and Kaito.
Some liquids, like flowing flames, produced a scorching heat the moment they touched the skin.
Other liquids, like arctic frost, slid over the hot skin, leaving an icy trail that chilled to the bone.
The intertwining of ice and fire produced an intense stimulation, unprecedented, extreme, contradictory yet harmonious at the same time.
In this "fusion experiment" full of cold scientific jargon and mad rituals, Kaito was completely lost.
It was no longer just a simple intertwining of emotion and desire; it was more like a shared exploration of unknown truths by two souls, the craziest chemical reaction mediated by the body.
(Ten thousand words are omitted here, enough to be published in a Nature sub-journal, detailing the shocking experimental process.)
...
The next morning.
Kaito woke up to a peculiar "beep-beep" sound.
He opened his eyes tiredly and found himself covered from forehead to ankles by dense silver sensors that glowed faintly.
The instrument beside the bed showed his stable heart rate and respiratory data.
The culprit, Agnes Tachyon, was wearing a white lab coat and glasses, like a doctoral student who had stayed up all night writing a paper, sitting at a nearby table with a pen in her hand, diligently writing in a thick report.
"Assistant-kun, are you awake? Excellent; it turns out I have some data from the second half of last night that I need to verify with you" she said without looking up.
Kaito struggled to sit up and looked at the cover of her report.
The title of the report was clearly written:
Preliminary Discussion and Verification Report on the Impact of 'Kaito' as a Biologically Active Polymer on the Physical and Mental State of Top Uma Musume as a Long-term Stable Partner.
Kaito's vision went black, and he almost fainted again.
At that moment, familiar voices were heard from outside the already dilapidated door of his bedroom.
"Knock, knock, knock! Kaito! Open up! Where the hell did you go last night?"
That was the furious roar of Gold City.
"Heh, heh, my dear protagonist, if you don't open the door soon, this Overlord will have to offer a splendid show of 'breaking down the door' in her own way; do you want that?"
This was the elegant threat of TM Opera O.
Accompanying the knocking were intermittent curses.
"It's all your fault, you crazy woman, for scaring him!"
"My goodness? Are you saying that as if you weren't the one who came running to bother him last night?"
Kaito heard the voices outside the door, then looked at the mad scientist who was still diligently writing her "experiment report" inside the room.
His three-way harem era, it seemed... had officially begun in a chaotic way that he could not control at all.
