The Grammatical Investigator in Conan

In a cheap apartment building in Tokyo.

A thin girl with short hair was kneeling in a tatami room, packing up the daily necessities on the low table one by one.

However, she did not plan to take these things anywhere, but to give the still usable things to the landlord, and find a place to throw away the personal belongings that could no longer be used.

Because she would never need these things again soon...

She was quick and nimble, and she separated the useful things from the unusable things and packed them one by one.

However, in order to pretend to be more like a high school student in the "Detective Koshien" starting the day after tomorrow, the school uniform from her student days had to be kept.

"I haven't worn this dress for a long time..."

"I don't know if it still fits?"

The girl with short hair pulled the curtains of the room halfway up, and her petite body shrank into the darkness that outsiders could not see.

At the edge of the gray fabric curtains, one piece of underwear after another was thrown casually on the tatami, which aroused people's endless reverie.

After a while, a young and beautiful figure reappeared at the window.

Nanatsuki Koshimizu stood in front of the dressing mirror and adjusted the scarf of her sailor suit and the wrinkles on the hem of her long skirt.

"It's OK~"

Except that her chest is a little squeezed, everything else is OK.

I'll just go to the tailor shop to have it altered tomorrow...

Natsuki Koshimizu looked at herself in the mirror with satisfaction, but within a few seconds, her vision blurred.

In a daze, she seemed to see another girl with twin ponytails wearing a sailor suit standing next to her, talking and laughing with her.

Kana...

I'll find that high school detective soon and avenge you.

Natsuki Koshimizu wore her school uniform and repacked her luggage.

When she packed to a photo frame on the table, she hesitated.

In the photo frame was a photo of herself and Kana Mizuguchi in high school. The two were wearing school uniforms and smiling brightly among the flowers.

The two were childhood sweethearts who had grown up together and had always had a good relationship and were almost inseparable.

After graduation, Nanatsuki Koshimizu was admitted to university and continued her studies.

Kana Mizuguchi chose to find a job directly and worked as a maid in a villa of a wealthy family.

Although the fate of the two was slightly different, they still kept in touch after graduation, and Nanatsuki Koshimizu would go to play with Kana Mizuguchi during holidays.

But fate is so tricky.

One day, Kana Mizuguchi called and said that the daughter of a wealthy family she served had hanged herself, and hoped that Nanatsuki Koshimizu, who had solved many cases, would come to help investigate.

So Nanatsuki Koshimizu asked for leave from school and came to Shikoku Island to investigate.

After a series of careful investigations, Nanatsuki Koshimizu was very sure that the daughter had simply committed suicide by hanging.

In addition, from Kana Mizuguchi, she learned that before the daughter committed suicide, she had just experienced a failed relationship and was deeply hit by a scumbag, and fell into depression for a time.

Therefore, the local police closed the case as suicide, and Nanatsuki Koshimizu returned to university after comforting Kana Mizuguchi.

But unexpectedly, half a year later, that incident happened...

Nanatsuki Koshimizu looked at the group photo on the photo, and the fingers pinching the photo frame gradually tightened.

But in the end, she reluctantly threw the photo frame and the photo into the useless garbage package classification.

Because once a murder occurs on an uninhabited island, there is a high probability that everyone's carry-on luggage will be searched.

This group photo cannot be kept on you anyway.

"Sorry, Chana."

Nanatsuki Koshimizu packed the two piles of luggage thoroughly, put one of the bags in a black plastic bag, and then put a "hazardous waste" label on the outside so that it would not be picked up by scavengers.

Just then, there was a knock on the door from the direction of the entrance.

Nanatsuki Koshimizu wiped the fine sweat on her forehead, and was startled at first, but then she remembered that it should be the landlord she had notified before coming to pick up the gift.

So, she didn't think about it anymore, and responded while standing up from the tatami.

"Here we go!"

She picked up the package in the transparent bag with both hands, and carried it to the door with great effort, then freed one hand to unlock the door.

But when the security door opened, the two figures at the door stunned her on the spot.

The mixed-race man standing in the front was tall and had a handsome uncle face.

Next to him was a short-haired... boy?

"Excuse me, who are you..."

Nanatsuki Koshimizu asked subconsciously, but suddenly felt that the man standing in front of her looked familiar.

Her brain reacted for a moment, and then she realized that she had some impression of this face.

This is one of the two most famous private detectives in Tokyo, the famous detective Qin Zhibo!

Nanatsuki Koshimizu's pupils trembled instantly, but she quickly suppressed the shock in her heart and asked calmly: "Who are you two?"

Looking at Nanatsuki Koshimizu's eyes turning from shock to vigilance, Qin Zhibo also knew that the other party had recognized his identity.

But he did not make it public, but introduced himself with a smile: "Let me introduce myself, my name is Qin Zhibo, and I am a well-known private detective."

"The person next to me is my disciple, Sera Masumi."

Sera Masumi took off his hat and gestured.

"I am here because my client received an invitation from a TV program called "Detective Koshien", but found that this program is not worthy of its name and is suspected of deceiving minors."

"In order to prevent minors from being persecuted by criminals, I was ordered to investigate the producer of "Detective Koshien"..."

Hearing this, Nanatsuki Koshimizu was startled and realized that the visitor was not friendly.

But she still suppressed her expression and asked calmly: "You went to find the producer of that program, and what's the matter with finding me?"

"I am also a minor..."

As soon as Nanatsuki Koshimizu finished speaking, Qin Zhibo took the program plan from Sera and showed it in front of Nanatsuki Koshimizu.

"The fake director Tsuchio Hiroo handed the program plan to me an hour ago and explained that he was instructed by someone."

"Based on our investigation, we believe that the source of this program plan should come from one of the participants of the program, Nanatsuki Koshimizu."

"In addition, Miss Koshimizu, your real age should be 20 years old, which is considered an adult in law."

Qin Zhibo looked at Nanatsuki Koshimizu's head and saw the age column clearly written: 20 years old.

Although she planned to pretend to be a minor to participate in Detective Koshien, in her daily life, her identity and age are still 20 years old.

However, Qin Zhibo's judgment surprised Shira who was standing by.

Because in her eyes, the girl in front of her was wearing the most common sailor suit for high school girls. Except for the brown hair, she looked like a high school student.

As for Nanatsuki Koshimizu, she was also stunned when she heard Qin Zhibo even said her real age.

Could it be that this detective has already investigated my information completely?

Nanatsuki Koshimizu frowned and wanted to make a final quibble and struggle, but Qin Zhibo did not give her a chance and continued.

"According to the current situation we have, Miss Koshimizu, your motive for planning this project should be the lavender villa case that occurred on Shikoku Island a year ago."

"In addition, I also have a very important piece of information about that case..."

"How about it?"

"Do you want to talk about it?"

Looking at the confident look of the man in front of her, Nanatsuki Koshimizu also knew that she had been investigated very thoroughly, and even her motives had been found out.

The revenge plan must have failed, and now she had to accept her fate.

"Okay..."

"Please come in."

Nanatsuki Koshimizu made way for Tomohiro Qin and Masumi Sera to come into the room.

...

Entering the room, there were several packages on the tatami floor, and the rest of the room looked empty.

"Miss Koshimizu, are you planning to leave here?"

"Yeah..."

Nanatsuki Koshimizu nodded, said nothing more, and turned to the kitchen.

After a while, she brought out two glasses of water and placed them in front of Tomohiro Qin and Sera.

"Sorry, there is only boiled water here now."

"It's okay, I'm not thirsty anyway."

On this side of the low table were Tomohiro Qin and Masumi Sera, and on the other side was Nanatsuki Koshimizu.

The two sides sat opposite each other, their eyes were full of confrontation.

Although Nanatsuki Koshimizu indirectly admitted that the program planning was related to her, she did not intend to expose all her plans.

And it was incredible that the other party could investigate her so thoroughly.

"Half an hour ago, Tsuchiwei called me. Did you ask him to make that call?"

"Not exactly..."

Qin Zhibo shook his head. "I actually called you by pretending to be Tsuchiwei, and then used technology to track your address."

"Because you are always waiting to participate in the 'Detective Koshien', I guess you should live not far from Tokyo Port."

"The result is exactly as I expected..."

Qin Zhibo told her the method he used to track down Nanatsuki Koshimizu without reservation, which made Nanatsuki Koshimizu look surprised.

Is this the strength of one of the most famous private detectives in Tokyo?

Although they are all detectives, she has only seen such technological methods as pretending to be someone else's voice and tracking the location of the other party's phone in spy movies.

I didn't expect that there would be detectives in reality who would use such high-tech methods...

It seems that she didn't lose unfairly.

"Okay, I really give up..."

Nanatsuki Koshimizu smiled helplessly, "But I prepared this project to compete with the best high school detectives in the country, and I have no other ideas."

"Of course, you can also sue me for using false information to deceive minors..."

"But the premise is that my deception has caused any losses to minors."

This is Nanatsuki Koshimizu's trump card.

Although she was caught by the pigtail, fortunately, nothing has happened yet. She was at most an attempted deception.

And in her program plan, there was no prepayment of registration fees, program shooting fees, etc. The police could only criticize and educate her.

The only pity is that her plan to avenge Kana can only be put on hold for a while.

Nanatsuki Koshimizu's completely irresponsible attitude made Sera Masumi slightly clench her fists under the table.

And Qin Zhibo is of course aware of these problems.

"You make a lot of sense. I really can't do anything to you..."

"But what if I say I know who the detective is who made the Shikoku police change the verdict of the Lavender Villa case half a year ago?"

As soon as Qin Zhibo finished speaking, Nanatsuki Koshimizu's pupils widened instantly and asked immediately, "Who is it!"

"Don't be impatient..."

Qin Zhibo's voice was still steady, "If you want to know the information here, you have to tell me your plan in full."

"Of course, from your point of view, it's just assuming that the immature reasoning competition plan can continue..."

Hearing this, Nanatsuki Koshimizu's eyes gradually calmed down.

She understood what Qin Zhibo wanted her to say.

Of course, it was the real purpose of her holding the "Detective Koshien".

Although those plans were related to her desire to avenge Chana, as Qin Zhibo said, everything was just based on assumptions and could not be convicted.

But correspondingly, she could get the name of the person who killed Chana.

As long as she waited until the storm was over, she would still have a chance to take revenge.

"Okay, then let's talk about my plan based on the assumption..."

Natsuki Koshimizu's expression relaxed slightly and she began her story.

In the "assumption", she planned to accept the invitation to go to the uninhabited island, but before boarding the boat, she bribed the boatman with money to let him conceal the location of the boat from all those who came to ask.

After that, she would see who solved the puzzle first after Tsuchio and Kotani Renzo finished the first puzzle.

Because the room on the uninhabited island has a lot of hints about the lavender case, plus the mystery of the murder in the closed room, the detective who "solved" the case half a year ago will definitely think of it immediately.

And she only needs to do what she should do after knowing the name of that person...

"What should be done?"

"Does it mean to kill that person?"

Qin Zhibo narrowed his eyes and asked Yueshui Nanatsuki.

The latter's mouth corners slightly raised, and he did not answer, but his attitude was obviously tacit.

Qin Zhibo saw this, so he continued to ask: "You are willing to do this, it should not be just because the high school detective once overturned your reasoning?"

"I'm afraid there are some deeper reasons?"

Facing Qin Zhibo's question, Yueshui Nanatsuki's eyes were extremely calm, and he asked back: "I have explained everything I should explain, and you should keep your promise and tell me the name of that person, right?"

But at this time, Qin Zhibo shook his head calmly.

"No..."

"Although I hate people who seek fame and reputation by solving cases, I am not so crazy as to get rid of such people in that way."

"So I will not tell you the name of that person until your revenge ideas change."

After being clearly rejected by Qin Zhibo, Nanatsuki Yueshui, who was calm the last second, suddenly glared at Qin Zhibo.

She put her hands on the table and yelled hysterically.

"What do you know!"

"That person killed my best friend! He doesn't deserve to live in this world!"

"Tell me the name of that person!"

Seeing Nanatsuki Yueshui suddenly go crazy, Qin Zhibo was also a little surprised.

But before he could stop her, Masumi Sera, who had been unable to bear it for a long time, suddenly stood up and slapped Nanatsuki Yueshui in the face.

"In this world, no one can judge other people's lives so easily!"

"You stupid girl!"
