"It can eat, drink, run, and jump!"

Ai Haibara silently recited this sentence in her mind, her gaze fixed on subject number one—Conan Edogawa.

After observing for a whole day, she finally concluded that Shinichi Kudo's physical condition did not seem to be affected in any way after he became Conan.

However, Shinichi Kudo's mindset underwent an unexpected change.

She developed a particular fondness for acting cute and adorable, and would even deliberately play the role of a child.

Ai Haibara couldn't help but ponder, wondering whether this change was due to her body shrinking, or whether Shinichi Kudo was always like this.

Ai Haibara, filled with suspicion, glanced thoughtfully at Conan in front of her.

A little while later, she packed her schoolbag and prepared to go home after class.

If it weren't for this subject worthy of observation and research, Ai Haibara felt she couldn't stay at school for even a minute longer.

...

"Haibara-san!"

Ai Haibara slowly turned her head, her gaze falling on Ayumi, who was panting as she caught up from behind. Her steps unconsciously paused for a moment.

"Haibara-kun, where do you live? Do you want to come home with us?"

Ayumi Yoshida, who has made many friends, has once again embarked on a journey to make new friends.

The two wingmen beside him, Mitsuhiko Tsuburaya and Genta Kojima, chimed in at just the right moment: "Yes, we can take you home!"

Looking at the three enthusiastic little guys in front of her, Ai Haibara's gaze slowly turned to Conan, who was deep in thought behind them, and a slight smile appeared on her lips.

“Okay, I live at 2-26 Beika-cho.” Ai Haibara replied softly.

"Boom!"

It was as if a bolt of lightning struck Conan's mind.

"Wait, isn't that Yuzuru Nanami's house?"

Looking up, Conan met Ai Haibara's gaze, which held a strange smile and lingered on him for a moment.

That look sent a chill down Conan's spine.

"Who exactly is she? Why is she living in Yuzuru Hanyu's house...?"

...

Hanyu House.

Akemi Miyano spent the whole day cleaning the villa thoroughly, inside and out.

She checked the time and it was almost time. She decided to give her sister a surprise—to personally pick up Ai from school on her first day.

After all, this is very meaningful to her, and it can be considered as making up for her past regrets.

After quickly changing her clothes, Akemi Miyano happily walked out of the villa.

...

"To pick up Ai from school?"

"Please take me with you, please take me with you..." Sonoko clung tightly to Yuzuru's arm, shaking it and pleading.

When Yuzuru announced that he was going to pick up Ai Haibara after school, Sonoko, who was standing next to him, couldn't contain her excitement.

She had long wanted to experience what it's like to be an older sister, but unfortunately her parents weren't very supportive, so she could only continue to be the younger sister.

"Sonoko, if you go with them..."

Feeling the sensation on his arm, Yuzuru Hanyu appeared to be in a difficult position.

(Hmm...that's it, just a little harder.)

"Ran..." Seeing that Yuzuru didn't speak, Sonoko turned to Ran with a pleading look, tightening her grip on her hands, afraid that Yuzuru would take the opportunity to slip away.

Noticing Sonoko's gaze, Ran blushed slightly, slowly walked to Yuzuru's side, reached out and hugged his other arm, and swayed back and forth with Sonoko.

"Alright, let's go together then!" Yuzuru said with a look of reluctance (satisfaction).

Upon hearing this answer, Sonoko excitedly stood on tiptoe and gave Hanyu Nan a quick kiss on the cheek.

Touching the spot where he had been kissed, Yuzuru glanced at Ran as if nothing had happened.

Feeling Yuzuru's fiery gaze, a faint blush gradually appeared on Ran's snow-white face.

Urged on by Sonoko, Ran shyly tiptoed and gently kissed Yuzuru on the cheek.

Both of them have gone this far.

Yuzuru nodded in satisfaction, took their soft, smooth little hands, and walked forward.

"Set off!"

"Wuhu, Xiaolan, let's charge together..."

...

Ai Haibara, on the other hand, has no idea what's about to happen!

Perhaps because her body had shrunk, the various hormones secreted in her body also caused some subtle changes in her mentality.

On a whim, she was seized by a playful impulse and readily accepted the invitation from the kids to join the Junior Detective Club.

And so, led by this group of daredevils, Ai Haibara is heading towards the location of the mission they finally received—to the home of the client, Toshiya, to investigate clues about his missing brother.

Conan, who was following behind the group, had absolutely no interest in this so-called elementary school game of pretend play.

He just kept staring intently at Ai Haibara in front of him.

"How did this guy suddenly appear next to me? And he's even living in Hanyu Nan's house..." Conan wondered to himself.

"And what exactly did she mean by the 'guinea pig' she mentioned earlier?"

Could it be that Ai Haibara, like herself, shrunk in size after taking that strange drug?

The more Conan thought about it, the heavier his mood became.

Because he always suspected that Yuzuru Nan had known his true identity all along, and was even very likely an accomplice of the mysterious man in black who had forcibly given him that pill!

The thought that he might have been constantly exposed to the other party's sight, and that Yuzuru Nan even went to flirt with Ran while he was away, made Conan grit his teeth.

"I will definitely investigate and find out your true identities!"

...

"I understand, thank you for your help, teacher!"

When Miyano Akemi didn't see Haibara Ai at the school gate, she went inside and asked a teacher. That's when she learned that her younger sister had run off to play with some classmates right after school.

"It seems like sending Ai to school was a really good idea. She's made new friends so quickly."

Akemi Miyano put her hands on her hips, feeling quite pleased with herself, thinking how clever she was to have come up with this idea.

"If my parents were still here, they would definitely praise me!" Just as Miyano Akemi was still immersed in her beautiful fantasy, she suddenly saw three people walking towards her.

"Oh, Master Yuzuru, you're here too..."

Before she could finish speaking, Miyano Akemi was stopped by a timely look from Hanyu Nan.
