Tokyo, in an affordable apartment building.

A slender girl with short hair was sitting on her knees in a tatami room, packing daily necessities on the low table one by one.

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

Because soon she will never need these things...

Her hands and feet are quick, she separates useful things from unusable things, and packs them one by one.

However, in order to look more like a high school student in "Detective Koshien" starting the day after tomorrow, I still have to keep the school uniform from my school days.

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

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

The short-haired girl half-closed the curtains in the room, and her petite body shrank into the darkness that could not be seen by outsiders.

On the edge of the gray fabric curtain, one piece of underwear was thrown on the tatami at will, causing people to have endless reveries.

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

Koshimizu Nanatsuki stood in front of the dressing mirror and straightened the scarf of the sailor uniform and the folds of the hem of the long skirt in front of the mirror.

“It’s okay~”

Except for the chest being a little crowded, everything else is fine.

Just go to the tailor shop tomorrow and have it altered...

Koshimi Nanatsuki looked at herself in the mirror with satisfaction, but within a few seconds, her vision became blurred.

In a daze, she seemed to see another girl with twin tails in a sailor uniform standing next to her, talking and laughing with her.

Chanel…

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

Koshimi Nanatsuki was wearing his school uniform and repacking his luggage.

When the package was placed in a photo frame on the table, she hesitated.

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

The two have been childhood sweethearts since childhood and have always had a close relationship, almost inseparable.

After graduation, Koshimi Nanatsuki was admitted to university and continued his studies.

Kana Mizuguchi chose direct employment and worked as a maid in a wealthy family's villa.

Although their destiny trajectories were slightly different, they still kept in touch frequently after graduation, and Koshimizu Nanatsuki would also visit Mizuguchi Kana during holidays.

But fate plays tricks on people like this.

One day, Kana Mizuguchi called and said that the daughter of a wealthy family she was serving had hanged herself. She hoped that Nanatsuki Koshizu, who had solved many cases before, could come and help with the investigation.

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

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

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

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

But I didn't expect that half a year later, that thing would happen...

Koshimi Nanatsuki looked at the group photo and gradually tightened his fingers on the photo frame.

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

Because once a murder occurs on an uninhabited island, everyone's luggage will most likely be searched.

This photo cannot be kept with you under any circumstances.

"Sorry, Chanel."

Koshimi Nanatsuki packed the two piles of luggage thoroughly. One of the bags was put in a black plastic bag, and a "hazardous waste" sign was posted on the outside so that it would not be picked up by scavengers.

At this moment, there was a knock on the door from the direction of the entrance.

Koshimi Nanatsuki wiped the fine sweat on his forehead. He was startled at first, but then he remembered that the landlord he had notified before came to collect the donated items.

So, without thinking any more, she stood up from the tatami and responded.

"Coming!"

She picked up the package in a transparent bag with both hands, struggled to carry it to the door, and then used her free hand to unlock the door.

But when the security door opened, she was stunned on the spot by the two figures at the door.

The mixed-race man standing at the front is tall and has a handsome face.

Following next to him is a short-haired... boy?

"Excuse me, are you..."

Koshizui Nanatsuki had just subconsciously asked, but suddenly he felt that the man standing in front of him looked familiar.

Her brain reacted, and then she realized that this face had some impression on her.

This is none other than one of the two most famous private detectives in Tokyo, the famous detective Qin Zhibo!

Koshizui Nanatsuki's pupils trembled for a moment, but he quickly suppressed the shock in his heart and asked calmly: "Who are you two?"

Seeing Koshizu Nanatsuki's eyes change from shock to vigilance, Qin Zhibo also knew that the other party had recognized his identity.

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

"The person next to me is my disciple, Shiliang Zhenjun."

Sera Masumi took off her hat and gestured.

"I appear here because my client received an invitation from a TV show called 'Detective Koshien', but found out that the show was not worthy of its name and was 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, Koshimi Nanatsuki was shocked and realized that the person who came was not good.

But she still suppressed her expression and asked calmly: "You went to find the producer of that program, what's going on when you find me?"

"I am also a minor..."

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

"The fake director Hiroo Tsutsuki handed over the program planning to me an hour ago, and fully confessed that he was instructed by someone else."

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

"In addition, Miss Yueshui, your real age should be 20 years old. At this age, you are considered an adult legally."

Qin Zhibo glanced at the top of Koshizu Nanatsuki's head, and the age column clearly read: 20 years old.

Although she plans to disguise herself as a minor and participate in Detective Koshien, in daily life, her identity and age are still 20 years old.

However, Qin Zhibo's judgment surprised Shiliang on the side.

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

As for Yuesui Nanatsuki, her expression was startled when she heard that Qin Zhibo even told her her true age.

Has this detective already fully investigated my information?

Koshizui Nanatsuki frowned, still thinking of making the final argument and struggle, but Qin Zhibo refused to give her a chance and continued.

"Based on the information we currently have, Miss Koshimizu, your motive for planning this plan should be the Lavender Villa case that occurred on Shikoku Island a year ago."

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

"How about it?"

"Do you still want to talk?"

Looking at the confident look of the man in front of him, Koshimizu Nanatsuki also knew that he was being investigated very thoroughly, and even the motive was found.

The revenge plan must have failed, and now we can only accept our fate.

"All right……"

"Please come in."

Koshizui Nanatsuki stepped aside half of his body and invited Qin Zhibo and Sera Masumi into the room.

…

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

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

"Um……"

Koshizui Nanatsuki nodded, said nothing more, and turned around and entered the kitchen.

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

"Sorry, we only have boiled water here now."
