After listening to Yuzuru Hanyu explain the capabilities of the Super Backpack,

Ai Haibara's eyes immediately lit up; her backache and waist pain were gone.

With a slightly amused smile, Ai Haibara blushed as she accepted the schoolbag.

She didn't decide to go to school because the backpack was so magical.

I'm just curious how Shinichi Kudo, who also shrunk and went to school, is doing now.

Yes, that's it!

Ai Haibara found a plausible excuse for herself in her mind, and then nodded.

Curious, he started fiddling with the new schoolbag.

Looking at her obedient younger sister, Miyano Akemi secretly gave Hanyu Nan a thumbs up.

Yuzuru raised his head, as if to say: It's nothing, don't you know who I am?

...

After dinner, Akemi Miyano rushed to her room to help Ai Haibara pack the various items she would need for school the next day.

Yuzuru's gaze fell on Ai Haibara, who was still holding her schoolbag and concentrating on studying its functions.

With a slight smile, he summoned the superpower training box.

He has indeed been slacking off lately, training for only one hour a day and not participating himself.

No matter how much Ai Haibara waved her little hands and legs, Nanami Hanyu still picked her up, and the two of them trained together, staring at the superpower training box.

Feeling the warmth around her waist, Ai Haibara looked up at Nanami Hanyu's focused expression and silently cursed him as a "pervert."

She stopped struggling and focused on training together.

...

The next morning.

"Ai, be a good girl and go to school with Master Yuzuru!" Akemi Miyano stood at the villa entrance, smiling as she saw the two off.

These past few days have been like a dream for her. Not only is her sister by her side, but more importantly, she no longer has to worry about threats from the organization.

Watching their figures gradually disappear into the distance, Akemi Miyano was filled with mixed emotions.

"Keep it up, work hard to repay Master Yuzuru!"

Akemi Miyano clenched her fist, gave herself a pep talk, and turned back to clean the villa.

What Miyano Akemi didn't know was that she didn't need to work so hard to repay him.

There is another way to repay the debt, which is also a way that Yuzuru Hanyu is quite satisfied with.

...

Teitan School.

Yuu Nan took Haibara Ai's soft little hand and walked into the administration office of Teitan School.

Last night, Yuanzi made a phone call and all the relevant procedures were properly arranged.

You should know that the Suzuki Foundation is an important member of the Teitan School Board of Directors!

"Hello, you must be Mr. Hanyu Kusunoki, Ai Haibara's parent, right? I am Rumi Wakasa, Ai Haibara's assistant homeroom teacher."

Accompanied by a flurry of footsteps, a woman in a light blue business suit, wearing glasses, and appearing somewhat clumsy, emerged from the office to greet them warmly.

"Hello, I am indeed Ai Haibara's older brother, Kusunoki Hanyu."

Yuzuru politely shook hands with Rumi Wakasa, while keenly noticing the thick calluses on her palms.

This seemingly ordinary female teacher is probably not as simple as she appears!

Yuzuru's gaze involuntarily fell on Ai Haibara, who was sitting on the sofa, leisurely swinging her legs.

Hmm! It seems that Rumi Wakasa is indeed not a member of the Black Party, otherwise Ai Haibara's organization detection device would have already started beeping.

After exchanging pleasantries with Rumi Wakasa, Nanami Yuzuru nodded slightly, leaned down, and whispered to Ai Haibara, "Ai, you must study hard. Don't bully other classmates, but if anyone dares to bully you, don't be shy. It's okay to fight back appropriately, just don't kill them."

Yuzuru clearly remembers that Shiho Miyano was bullied when she was in school.

Ai Haibara raised her head and met Yuzuru Hanyu's gaze. The tenderness in the man's eyes warmed her heart, and she nodded obediently to show that she understood.

Rumi Wakasa witnessed all of this...

Do you want to hear what you're saying?

"Are all these powerful and wealthy families so domineering?" She subtly wiped the sweat from her forehead as she looked at the two people in front of her. They spoke in the most gentle and friendly tone, yet their words were so cold.

However, these things didn't concern Rumi Wakasa much, since she was just an ordinary assistant homeroom teacher.

...

"Have you heard? Starting today, our class will have another transfer student!"

"Really?" Genta asked excitedly upon hearing Ayumi's words.

Mitsuhiko chimed in, "Ever since Conan came, there haven't been any transfer students!"

"I wonder what kind of person they will be?"

Seeing the three excited children, Conan listlessly put his schoolbag away.

Conan has been feeling very tired lately. He finally managed to find some information about the Men in Black last time.

When he finally located the place where the man in black might be, a fire had already broken out there, and the trail went cold.

"Sigh! I still have to accompany these kids to school!"

Conan covered his head with a book, feeling as if everything was in darkness.

"Hey Conan, what kind of person do you think the other person is?"

Ayumi ran over and nudged Conan, who was slumped over the table.

"I think he's just a bookworm who only knows how to read!" Conan said impatiently, but then felt a chill run down his spine.

What happened?

Conan abruptly pulled back the book covering his eyes and saw Rumi Wakasa walking in from the podium with a girl with brown hair. The girl's lake-blue eyes were coldly staring at him.

"Heh, what's going on?" Conan's lips twitched, startled by the other person's gaze.

"Is this Shinichi Kudo?"

Ai Haibara stared at Conan below, as if she had seen a very interesting toy.

"This student's name is Ai Haibara, everyone please welcome her!"

Rumi Wakasa wrote her name on the blackboard and led the applause.

"This name is so strange, it sounds like my name?" Conan clapped listlessly, a strange sense of familiarity rising in his heart.

Conan stared intently at Ai Haibara on the podium, then was surprised to find her walking towards him.

"Hello, little white mouse."

"Huh?" Conan stared blankly at Ai Haibara sitting behind him, completely bewildered by her words.

What guinea pig? Are you saying I look like a guinea pig?

Conan, who wanted to turn back and ask again, had no choice but to turn away when he heard Rumi Wakasa say that class was in session.

Looking at Conan's back in front of her, a light flashed in Ai Haibara's eyes.

"Shinichi Kudo, the first successful human subject for APTX4869!"
