Nagai Hikaru's Ke Xuexing

On Thursday at noon, Haibara Ai secretly set fire to the tulip fields, hoping that the teacher would postpone the parent-teacher open class.

She calmly listened to Conan's reasoning that she was the murderer who set the tulip fields on fire, touching the water stains in her pocket, and felt unexpectedly calm.

"I asked her to do it! It's not Ai's fault!" The little girl with twin ponytails and glasses shouted from behind, "I just wanted to cancel the open class so that mom wouldn't have to force herself to attend!"

Teacher Kobayashi suddenly realized: "So that's what's going on. Maria's mother barely managed to come to the last music concert, and her back pain got worse."

Conan looked at Haibara Ai for half a month and had a feeling that this was how it was. At this moment, he finally remembered something he had not told her this week.

After the principal punished Haibara Ai and Maria to take care of the tulip fields together for a month, Conan pulled Haibara Ai aside and whispered, "Ah, Haibara, I forgot to tell you before."

"Oh? The great detective also has bad memories sometimes?"

"It's Xiaoguang. He said he would come and be your parent." Conan was already accustomed to Haibara Ai's sarcasm and automatically omitted the sarcastic part.

"elder sister?"

"Yes, he said he would come as your sister." Conan laughed dryly, waved his hand, and said delicately, "So you don't have to worry about not having parents come to see you, your sister will definitely be the most conspicuous among the parents."

Huiyuan Ai grabbed the corner of her still wet clothes and said, "Sister, will you be my parent?"

"Well, so be mentally prepared." Conan felt stressed just thinking about his childhood sweetheart standing in the parents' seat and watching him take a second-grade class.

Kudo Yukiko, who was dressed as Edogawa Fumiyo, was surprised when she saw Nagai Hikaru in a white dress.

"Xiao Guang? Why are you here?" She was holding a tablet in her hand, on which was a live video broadcast of Maria's mother.

Nagai Hikaru lifted her blonde hair, and the red rose headband on her head was unusually bright: "I am Ai's sister. Of course I have to come to the parent open class."

"How cute." Edogawa Fumiyo smiled, covering her mouth with her hands, "I thought you were here to see Conan."

"Of course, Conan can also take a look." Nagai Mitsuru approached Edogawa Fumiyo with a smile, holding a small red handbag in his hand, and walked into the classroom with Edogawa Fumiyo's arm.

In class, Teacher Xiao Lin pointed to the question on the blackboard and said, "Think about it, what number should be filled in this square? Raise your hand to answer."

The children raised their hands enthusiastically.

Fumiyo Edogawa was holding a tablet, and Maria's mother was sitting on the hospital bed, looking at her child with shining eyes.

"Ah, Conan raised his hand." Nagai Mitsuru let go of Edogawa Fumiyo's arm and put his hands together with a smile on his face, "Great, Conan is so smart."

Conan raised his hands and lowered his head, wanting to bang his head against the desk to death.

Teacher Kobayashi smiled and said, "Mr. Edogawa, then you answer it."

"...I think it should be 2." Conan stood up and answered with a look of despair.

"Conan is amazing!" Nagai Hikaru applauded excitedly, "What a genius! He will definitely be able to get into the University of Tokyo!"

Conan glanced at Haibara Ai, who was covering her mouth and laughing so hard that tears were about to come out, and sat back on the chair with a thump: He was only thinking about moving Xiaoguang to become Haibara's parent, and completely forgot about Xiaoguang's bad character.

When the get out of class was over, Nagai Hikaru happily walked to Huihara Ai, unable to hide the smile on his face: "It's so interesting, Ai, I've decided to come and watch your parent open classes in the future."

Huiyuan Ai wiped the tears from her eyes and stood up: "Sister, don't you have to go to class today?"

"I don't have classes today, but even if I did, I would still take a leave for Ai." Nagai Mitsuru said happily.

Himimi walked up to the two of them, looked up at Nagai Hikaru, and timidly said, "Are you Ai's sister?"

"Yes, you can just call me Sister Xiaoguang." Nagai Mitsuru bent down and touched Himimiyuki's head, pressed down the horns on her head, and looked at the hair that bounced back.

Maori Kogoro walked over and scratched his ears: "Xiaoguang, isn't it a bit too bold for you to come out like this? The file says that you are..."

Before he could finish his words, Nagai Mitsuru nodded and said, "It's amazing. Anyway, I'm standing in front of you now."

Maori Kogoro gave up and shrugged his shoulders: "Forget it, I can't control your affairs." Then he squatted down and looked at Hime Miyuki with a smile on his face, "Meiyuki is great, she raised her hand for every question in class just now!"

Himimi was shy: "Actually, Ai can do it too, she's just too embarrassed to raise her hand."

"It's really great that Miyuki had the courage to raise her hand!" Kogoro Mouri picked up Miyuki Kisaki and walked towards Fumiyo Edogawa.

Even if the other children noticed Nagai Hikaru, their attention was distracted by him talking to his parents.

Nagai Hikaru squatted down and looked at Huihara Ai, and said with a smile: "Do you want me to carry you home after school?"

Haibara Ai stuffed her books into her schoolbag and nodded obediently.

Wakasa Rumi came over and stood next to Huihara Ai's desk: "Hello, are you Huihara's parent?"

"Yes, I'm her sister." Nagai Hikaru stood up and said, "Hello, Mr. Wakasa. Thank you for taking care of Ai at school."

Wakasa Rumi looked closely at Nagai Hikaru's face and said, "You two don't look much alike."

"Because I look like my mom and she looks like my dad." Nagai Hikaru said as a matter of course, "But it's obvious that we are both mixed-race, right?" Nagai Hikaru pointed to his face and said proudly, "You can tell from our faces that our parents are both handsome and beautiful."

Wakasa Rumi looked at Nagai Hikaru carefully: "You seem to be similar to the person online recently..."

"Ah, you know, in some families, the family relationships are more complicated." Nagai Mitsuru raised his hand and made a pause gesture, with an expression that this matter was very complicated, and it would be a bit presumptuous if you asked again.

Wakasa Rumi looked down at Huihara Ai again, then smiled and said, "Huihara-san is very smart and often knows some very advanced knowledge for her age. Your education is very good."

"It has nothing to do with our education, it's just that our family has a smart bloodline." Nagai Hikaru raised his head proudly: "Ai watches Magical Girl Detective and will figure out every detail on her own and even check it online. She will immediately figure out if there is something she doesn't understand. She is a very serious child."

"Is that so? I always think she's too smart to be a child." Wakasa Rumi looked at Nagai Hikaru again, "But I just found out she has a sister."

"Because our parents are gone and I have to go to school, I let Ai live with Professor Agasa." Nagai Mitsuru said obediently, holding her handbag with both hands.

"Oh, so Sister Huibara is still studying? Which high school is she attending?"

"Eastern University."

Wakasa Rumi was surprised: "You're already in college?"

"I told you, our family has a smart bloodline." Nagai Hikaru blinked and raised his hand to adjust the red rose headband. "Teacher Wakasa is very concerned about Ai. Is there a problem?"

"No, I just think..."

"Teacher Wakasa," Nagai Hikaru interrupted, "Speaking of intelligence, I think Ai's friends, the kids from the Junior Detective League, are all very smart and sensible. I hope the teacher can treat these kids more equally. I hope she can have a complete childhood."

Haibara Ai looked up at Nagai Hikaru and held his hand.

Parents took their children out of school and began to leave the campus one after another.

Mitsuhiko Ayumi and Genta turned around and looked at Hikaru Nagai in confusion, then took their parents' hands and left the classroom.

Nagai Hikaru pulled Haibara Ai and followed behind Edogawa Fumiyo and Mori Kogoro.

Ai Huihara carried her schoolbag and looked up at Hikaru Nagai: "Sister..."

"You are my biological sister. I made the decision unilaterally." Nagai Hikaru patted his chest confidently, "I will pay child support to Dr. Agasa."

"…No. That's not what I wanted to talk about. That Wakasa-sensei is weird…" Huibara sighed. She was thinking about talking about alimony, but just because of the long-term cooperation with Fusae, the doctor has now achieved complete financial freedom.

"I can see that one of her eyes seems to be a prosthetic eye, right?" Nagai Mitsuru nodded.

Shiraha Yuba, who was waiting at the school gate, walked forward and stood on the other side of Nagai Hikaru, walking side by side with him.

"Have you seen Wakasa Rumi?" Nagai Hikaru turned to look at Hashira Hana.

Hanaba Haku nodded: "That woman... might be very strong."

"Ah?" Haibara Ai looked at Hashira Haba.

"When I was at OK Ranch, I picked up a shogi piece. But after I was ambushed and knocked unconscious, the shogi piece disappeared," recalled Hanaba. "At the time, the only people around who could take action were her and Kobayashi Sumiko."

"Do you suspect that she attacked you and knocked you out?" Nagai Mitsuru took off Haibara Ai's schoolbag naturally, handed it to Hakuhata, then bent down, picked up Haibara Ai and continued walking.

"Well, she's more likely than Xiaolin." Habashiro took Huihara Ai's schoolbag and carefully recalled the scene at that time. He clenched his other hand into a fist and then unclenched it, frowning and saying, "I was locked in the basement at the time. It was very dark around me. I was knocked down in just a moment. That person is much... stronger than me."

"…Investigate her!" Nagai Hikaru frowned, his face serious, "Why is she in this class? And she's targeting Ai, it's definitely not a coincidence."

"Yes."

"Her left eye is a prosthetic one, so it should be easier to start from there."

Haibara Ai was shocked by Nagai Hikaru's serious look. She pulled the lace edge of the collar of Nagai Hikaru's white skirt and whispered, "Is it okay? I'll be more careful."

"Ai, this isn't just a safety issue for you, it's also about Miyuki and Conan." Nagai Hikaru patted her back gently, "Don't worry, I'm just being safe."
