"This is..."
Ai subconsciously raised her arm, her fingertips easily touching the back of her shoulder—a movement that usually required some effort, but now it was as easy as breathing.
Akemi suddenly realized: "So that's what 'flexibility' means!"
"It seems the effect is even better than expected."
Yuzuru's voice was clearly filled with pleasure.
The moment he saw the effect, he immediately thought of the best way to use it.
After all, Ai Haibara in her loli form is already quite flexible; adding even more flexibility means...
Those small games that were previously unplayable due to physical limitations.
Now all of these are possible.
Just thinking about it is a little exciting.
Akemi looked at her younger sister and chuckled softly, covering her mouth: "Ai looks just like a little kitten right now."
"No way!" Ai tried to respond in her usual indifferent tone, but the unusual softness of her body made her seem a little unsure of herself, and her voice unconsciously carried a hint of coquettishness.
She tried to break free from Yuzuru's embrace, but found that her waist felt boneless, easily encircled by his single arm.
Hanyu Nanami's fingertips gently pressed against Ai's waist, feeling its incredible flexibility. "Miss Scientist, in order to accurately record the data, I think we need to conduct some basic tests."
"well?"
The haughty little girl was stunned and didn't react.
Mingmei, as if on cue, promptly handed over a measuring tape: "Young Master, would you like some measuring tools?"
"How thoughtful." Yu Shengnan took the measuring tape.
Then he turned to the little girl in his arms, “First, let’s test the range of forward bend.”
Before Ai could react, Yuzuru had already gently grasped her smooth, delicate ankle and slowly pulled her slender leg forward, as if handling a fine work of art.
Surprisingly, Ai's body was almost folded in half, her forehead easily touching her knees, and her short brown hair fell between her legs.
"Perfect score!"
Yuzuru couldn't help but sigh, his gaze falling on Ai's taut back as she bent forward, her pajamas rolled up with the movement, revealing a section of her fair, snow-white lower back.
Ai quickly straightened up, angrily pulling off her clothes: "Enough! This kind of test has no scientific value whatsoever!"
"How could that be?" Yuzuru shook his head, feigning seriousness. "Next, we'll test your side-bending ability."
As he spoke, he placed one hand on Ai's shoulder and gently pushed her waist to bend to the side with the other.
Xiao Ai gasped in surprise, her body bending into an exaggerated arc like a willow branch. Her loose neckline opened due to gravity, revealing her delicate, porcelain-like collarbone and a small patch of snow-white skin, exuding a faint girlish fragrance in the air.
Yu Shengnan's fingers unconsciously lingered on her waist for a few more seconds.
"Yusuke Kusunoki!"
She struggled to return to her original state, but her body was too flexible, making it impossible for her to exert any strength. She could only hang on his arm like a limp ball, looking helpless and coquettish.
Akemi, watching with great interest, interjected at the opportune moment: "Young Master Yuzuru, how about we test if Ai can do the splits? I remember she could never do it in gymnastics class before..."
"Sister!" Ai glared at her older sister in embarrassment and indignation, only to be met with an innocent blink.
Yuzuru chuckled softly, "Good idea."
His hand slid down Ai's leg and gently grasped her knee. "Cooperate, Miss Scientist."
"I don't want to—ah!" Ai's protest turned into a short scream, because Yuzuru had decisively spread her legs apart and easily pulled her into a split.
What humiliated her even more was that, due to her greatly improved flexibility, her hips were almost completely pressed against the sofa, even more exaggerated than a standard split.
"Perfect!"
Yuzuru's gaze swept intensely over Ai's legs, which were tense from the movement. He gently pressed his fingers on the inside of her thigh and immediately felt the skin there tremble slightly due to its sensitivity, as if a string of a musical instrument had been gently plucked.
He added, "It seems that not only coordination has improved, but also muscle elasticity."
Ai's face turned as red as a ripe apple. She tried to close her legs, but due to her flexibility, she temporarily lost precise control of her muscles and could only twist her body in vain, angrily saying, "Let me go!"
Yuzuru, of course, pretended not to hear Ai's protest.
"The last test."
He released Ai's legs, then grabbed her waist with both hands and lifted her up with a gentle motion.
Xiao Ai gasped in surprise, instinctively wrapping her legs around his waist and her arms around his neck.
"Reverse bow test".
As Yuu Nan spoke, he steadily supported her hips with one hand, giving her ample support, while his other hand gently held her back, guiding Ai's upper body to bend backward into a graceful arc.
This position meant Ai's chest was almost touching his face, and the loose neckline of her loungewear was wide open, revealing glimpses of what lay beneath.
"I don't want to, let go of me..." Ai struggled, but her newly acquired flexibility allowed her to wriggle nimbly like a cat, almost causing Yuzuru to lose his grip.
Akemi smiled indulgently, "Young Master, be careful, Ai is very 'soft' right now~"
After finally managing to hold her properly again, Yuusuke chuckled and slowly straightened Ai's body, deliberately keeping her legs wrapped around his waist.
"Test results show that... flexibility has increased by about 300%, and muscle elasticity has increased by about 200%."
"What nonsense are you spouting!"
Ai finally regained some strength, but because of the large movement, she slipped out of Hanyu Nan's arms and hung on the sofa in an unbelievable position—her waist was bent into a beautiful arc and her legs could almost touch her shoulders.
The three of them were stunned at the same time.
A moment later, a dangerous glint flashed in Yuzuru's eyes: "It seems... we need to expand our experimental projects."
Akemi smiled gently and took Ai's hand: "Ai, shall we... help the young master test the effect together?"
She also ate the egg tarts that added chewiness.
Ai glanced at her sister's expectant eyes, then glared angrily at Yuzuru, only to find that her anger couldn't be mustered under the man's smiling gaze.
She turned her face away, choosing to bury her head in the sand like an ostrich.
I neither agree nor refuse.
Anyway, she was forced by her older sister and Yuzuru.
Yuzuru chuckled, putting one arm around Akemi's waist and picking up Ai with the other: "Then let's start with the most basic flexibility test..."
The sound gradually faded away at the corner of the stairs, leaving only the half-eaten egg tart on the coffee table and the sweet aroma that filled the air.
