The goal is the Faculty of Medicine of Dongdae

After the detective agency regained consciousness, Atsushi Nakajima felt the long-lost relaxation.However, he immediately began to worry again, for no other reason than because of Izumi Kyoka who was brought back, he was not sure whether the detective agency would accept Kyoka who had killed 35 people.

When he saw that Kyoka was dressed in a maid outfit and was surrounded by Naomi Tanizaki and Miss Haruno excitedly, the corners of his mouth twitched, but he was inexplicably relieved.

Is this accepted... Nakajima Atsushi thought in his heart, he looked at Kunikida Doppo, who pushed his glasses: "Although the military police and the city police have set up an investigation team, but because Mafia works on the secret identities of the members, It should not have been exposed so far."

"But it's only a matter of time."

Atsushi Nakajima looked at Quan Jinghua worriedly, and the other party pursed his lips: "I want to stay here, I don't want to kill any more, I want to prove my worth."

With that deep determination and reason, Kunikida Doppo couldn't say anything against it.

"Then wait for the president to come back and decide."

"I'm back!" Edogawa Ranpo excitedly pushed open the door, and the one who stepped into the room was Fukuzawa Yukichi, the president of the Armed Detective Agency.

"President!"

Fukuzawa Yukichi nodded calmly, and was about to say something when the phone rang suddenly.Atsushi Nakajima hurried over and picked up the phone: "Hello, this is the Armed Detective Agency. Do you have any commission?"

"Good afternoon, Nakajima-kun."

Atsushi Nakajima was stunned when the slightly smiling voice of a young man rang in Atsushi Nakajima's ear.

"You still seem to remember my voice, so it would be great." Although the voice on the phone was slightly distorted, Atsushi Nakajima could still feel a certain pleasure revealed in the words, "I have some Something I want to talk to you about."

"Dun, what did the client say?"

"It's... the call from the young master of Mafia." Atsushi Nakajima raised his head, Kunikida Doppo and the Tanizaki brothers and sisters changed their expressions together, "The young master of Mafia at the port?!"

"According to the news, the port Mafia searched Yokohama a few days ago just to find this so-called 'young master'." Kunikida Doppo flipped through the ledger, his voice became serious, "Why did he call Looking for a detective agency?"

"Uh...that, Mr. Kunikida..." Atsushi Nakajima said awkwardly, "I...signed a treaty with that young master..."

"What?! Atsushi, what are you thinking!" Kunikida Doppo was almost pissed off by Atsushi Nakajima. He held back his anger and waited for Atsushi Nakajima to quickly explain the contents of the so-called treaty, and his frown quickly changed. Into a section of the geological layer, "What about the treaty?"

"It seems... the share I gave fell into the sea..."

Kunikida Doppo pressed his heart, with an expression on the verge of myocardial infarction.

"Mr. Kunikida, are you okay!" Atsushi Nakajima rushed up immediately, and Doppo Kunikida stood up firmly, "I, it's okay, what is he calling this time?"

"Say something you want to talk to us about." Atsushi Nakajima ran back to pick up the phone and pressed the speaker button.

"It seems that you have forgotten what I said before, Nakajima-kun." The boy's voice didn't change much, it was still as calm as ever, "But it doesn't matter, it doesn't conflict with what I want to say today. "

All members of the Armed Detective Agency quietly listened to the other party's words echoing in the room.

"Are you interested in making a deal, Nakajima-kun." I could hear the slight sound of the cup touching the table, and the silver spoon made a pleasant ding-dong sound with the cup wall as it rotated, "About you, Ms. Izumi Jinghua .”

Atsushi Nakajima subconsciously looked at Izumi Kyoka. The girl in kimono still had no expression on her face. He turned to Kunikida Doppo for help, who was lip-syncing to him, "Ask the specific content."

"Don't worry, I don't want to start a war with you. To show my sincerity, I'm already waiting for you at the Whirlpool Cafe on the first floor."

The black-haired young man sitting alone at the corner of the coffee shop took a sip of his coffee: "That clever detective can participate if he is interested, but I came alone, so I suggest no more than three people."

"What is your decision?"

"Mr. Kunikida..." Nakajima Atsushi looked at Kunikida Doppo, Kunikida Doppo looked at Fukuzawa Yukichi, Fukuzawa Yukichi was silent for a few seconds, looked at Edogawa Ranpo, and Ranpo stuffed a mouthful of potato chips, "If you want to promise, just promise."

"Ranpo..." Fukuzawa Yukichi spoke, and Edogawa Ranpo puffed up his face, "President, Ranpo-sama has never met that guy, and he didn't even clarify the treaty that Atsushi said. However, There will be no danger."

He is a detective, but it must be based on real evidence, not imagination.

"Then promise him." Kunikida Doppo resolutely said.Atsushi Nakajima nodded, "We agree."

"Then I'll be here to greet you."

The black-haired boy cut off the communication, but he didn't close the phone, but tapped something quickly on the keyboard.

"Well, Mr. Kunikida, I just remembered that the 'young master' said something strange to me before." Atsushi Nakajima said, "He asked me to ask you, what is the null hypothesis and the opposite hypothesis... ..."

"This is a statistical concept." Kunikida Doppo frowned, "The content of the hypothesis of the null hypothesis is generally a hypothesis that hopes to prove its error. For example, in the correlation test, "there is no relationship between the two" is generally taken as the Null hypothesis, and the opposite of the null hypothesis is the opposite hypothesis, that is, another possibility that hopes to prove to be correct, and can also be understood as the remaining possible results of the null hypothesis.”

Nakajima Atsushi and Tanizaki brothers and sisters had blank expressions on their faces, and Kunikida Doppo couldn't help feeling angry when he saw this: "Forget about Atsushi, Tanizaki, you went to school, why don't you even know this."

"That...we're not very good at math..." Junichiro Tanizaki smiled awkwardly.

"Isn't it obvious? That guy wants to tell us that the purpose of the 'buyer' who bought a human tiger is not for the superpower of 'becoming a tiger'." Edogawa ranpo chewing potato chips , "Also, he let Dun go on purpose."

"what?!"

"Can't you see that, Kunikida-kun." Edogawa Ranpo squinted his eyes and said, "When you rushed to the seaside port, didn't you even meet a guard who stopped you?"

"Indeed, I boarded the yacht so smoothly... It's a bit strange now that I think about it..." Kunikida Doppo frowned and thought deeply, "What the hell is that guy trying to do..."

"This doesn't belong to the category of famous detectives. A famous detective is only responsible for seeing through the truth, and doesn't care what other people are thinking."

"In that case, Don, I'll go with you."

"And me." Quan Jinghua said.

"Jinghua, this is too dangerous for you!"

"If I want to join the detective agency, I will definitely face it." Quan Jinghua said firmly.

"But including Mr. Ranpo, there are more than three people..."

"Ranpo and I are waiting on top of the detective agency." Fukuzawa Yu said, "Kunikida, take this with you, and send the password immediately if you are in danger."

"Yes, President."

It didn't take much effort for them to see the boy sitting in the corner drinking coffee and reading a book. He was indeed alone as the other party said, but Kunikida Doppo didn't relax his vigilance. It's too easy to hide people around here.

"Good afternoon, everyone in the Armed Detective Agency."

The teenager closed the book, and Atsushi Nakajima saw the words 'Analysis of Human Nerve Distribution' written on the cover.He put the book on the table casually, and said to the waitress: "Please give me another chocolate parfait, what do you want to drink?"

"Ordinary coffee." Kunikida Doppo said quickly, and Rintaro nodded, "Nakajima-kun, Miss Izumi, how about you?"

"Uh, I'm the same as Mr. Kunikida, Kyoka, why don't you have a glass of milk?" Atsushi Nakajima noticed Kunikida Doppo's gaze of 'Underage not allowed to drink coffee' and said hastily.

Quan Jinghua grabbed Nakajima Atsushi's sleeve and remained silent.

"Two cups of coffee and a cup of milk, please put it on their account." The boy said happily.

Atsushi Nakajima twitched the corner of his mouth.

"I know everyone's time is precious, and so am I. Then, please let's get to the point." Rintaro said, he put his hands crossed on the table, his back straightened slightly, and Kunikida Doppo and Nakajima Atsushi couldn't help but change their minds. Get serious.

"First of all, I was entrusted by Hongye-san to come to confirm Miss Izumi Kyoka's thoughts." Rintaro looked at Izumi Kyoka who was wearing a kimono, the girl raised her head and stared at him, her blue eyes showed no expression , "Miss Quan Jinghua, have you confirmed that you left the organization voluntarily and joined the Armed Detective Agency instead of being coerced, threatened or otherwise involuntarily forced?"

"Of course she did it voluntarily! You guys have been coercing her to kill people!" Atsushi Nakajima couldn't help shouting, but the boy raised his hand to stop him, "I'm asking Quan Jinghua now. Miss, only her own expression is valid."

Quan Jinghua silently grasped the corner of Atsushi Nakajima, raised her head, her sky blue eyes were extremely firm: "I don't want to kill any more, I want to join the detective agency, I won't go back."

"Kyoka." Nakajima Atsushi held Izumi Kyoka's hand, "I will ask the president with you to stay in the detective agency."

"Okay." Lin Taro didn't seem to be touched by such a moving scene, he bent down and took out a box from under the table, and pushed it over, "Here are the supplies and clothes Miss Izumi Kyoka put in the organization, and, Since you left the organization before the full month, all wages for this month will be deducted."

"Also, here is a document, please Ms. Izumi Jinghua sign on the spot. After leaving the organization, the organization will no longer provide any help and protection, as well as your subsequent compensation due to your actions against Akutagawa. The corresponding expenses will be deducted from Miss Jinghua's salary card."

Atsushi Nakajima felt in a daze that what he was facing here was not a vicious Mafia, but a property transfer law department dealing with civil disputes.

From the corner of the eye, I saw Quan Jinghua take the document and sign it without hesitation, and Atsushi Nakajima, who had no time to stop him: "Wait...wait?"

"Have you read the entire content? This has legal effects." Kunikida Doppo frowned disapprovingly, but Izumi Kyoka said, "I have made up my mind, and I can do anything to join the detective agency. You can give up anything."

"But... wait, didn't you Mafia issue a killing order to the traitors?"

"Oh, regarding this point, Hongye-san has already saved Ms. Izumi Kyoka, so no killing order will be issued." Lin Taro turned the pen casually, "Therefore, we decided to deal with Ms. Izumi Kyoka's resignation through normal resignation procedures." Behavior."

"Normal...resignation procedures?" Kunikida Doppo frowned, why didn't he know that Mafia had allowed normal resignation?
