Arriving at the desk, D saw the recording button on the phone on the desk shining, so she pressed it with one hand, and then a voice sounded.

“It’s me. I have something I need your help with. I’ll come to your place later.”

 “Dot? What trouble is he in?”

This voice is not unfamiliar to D. He is a policeman in the city where D is currently located. The two parties have cooperated several times. Generally speaking, Dot is a policeman with a strong sense of justice, and the two parties get along well. He also entrusted D to help investigate and solve several electronic demon cases.

 The call this time was probably for this reason.

Due to the Doomsday, satellites around the world have basically exploded, and the base stations used to transmit signals have been destroyed. For the sake of safety, mankind has now returned to the era of landlines and public telephones. After all, this is Gadgets are not afraid of being invaded and destroyed by electronic networks.

D doesn’t care about this, and it still has a retro aesthetic. Of course, it may be more troublesome for modern people who are accustomed to using mobile phones.

 “Dong dong dong.”

At this moment, there was a knock on the door. D sat on the chair and then changed his position.

 “Please come in.”

　　With D's voice, the door opened, and then a man wearing a police uniform walked in.

 “Yo, good morning, Duanmu.”

 “Good morning, Dot.”

 D also said hello to the man in front of him. Since it is anonymous now, the name D cannot be used. After all, in current education textbooks, D is included in the textbooks as a figure who influenced human history. It is too dangerous to use this name again.

 So...D decided to change the name.

 That’s right, what’s in front of you now is the 17-year-old youthful and invincible cute girl idol, Duanmu Ai! (<ゝω·)~KIRA☆

 Ahem, okay, the joke ends here.

 “You have a case for me?”

“Yes, this case is a bit strange.”

 Duanmu Huai - No, Duanmu Ai and Dote have had many interactions with each other, and they are familiar with each other. Dote also knows that this girl does not like to be polite, so he gets to the point directly. He took out a file and placed it in front of Duanmu Ai.

“Not long ago, we received a report that a teacher in a school was bullying students.”

"Um………"

This is not surprising to Duanmu Ai. After all, no matter what era or place, human beings will be divided into three, six or nine classes, and fights between each other are inevitable. Not to mention schools, bullying also exists within workplaces, companies, businesses and even families.

 It’s just that people who are bullied in a company or unit can just smash the keyboard into the other person’s face and shout “I’m quitting”, but unfortunately students don’t have this ability.

“I accepted the case and then investigated it, and found that the physical education teacher in that school was highly suspicious. According to the secret investigation, he was very likely to abuse and bully the students in the name of training.”

“So you don’t want me to disguise myself as a student and break into the school to investigate this matter.”

  “Half right.”

Hearing Duanmu Ai’s question, Dote chuckled.

 “In fact, the case is closed.”

　　　……Are you kidding me?”

Duanmuai stared at Dot, and if the latter said something wrong, she would smash the pear wood desk directly into his face.

 “Listen to what I have to say first.”

Seeing Duanmu Ai's expression was wrong, Dote also waved his hand hastily.

"It is indeed difficult to investigate this kind of bullying case, but we are not without progress, because during our investigation, a female student tried to commit suicide by jumping off the building because she couldn't stand the bullying by the teacher. Fortunately, she was rescued Come here. According to the results of our police examination, she has a lot of old bruises on her body, which are obviously beyond the scope of ordinary exercise from a medical point of view, so we want to ask her after she wakes up, if this If the female students are willing to assist the police, then we can take down that scum in one fell swoop!”

"but?"

"But... before the girl woke up, the teacher took the initiative to surrender."

"…………Aha?"

Hearing this, Duanmu Ai opened his eyes in surprise, and Lumiere standing next to him also showed an unexpected expression.

“Yes, he surrendered himself and confessed his criminal experience to us very heartbrokenly. He is currently in jail and awaiting trial.”

 “Isn’t this great? What’s the problem?”

From Duanmu Ai’s point of view, there seems to be nothing particularly strange about this case.

“Indeed, this is the reaction of most people.”

 Dot nodded.

“However, this case is a bit unusual. At least from my investigation, the teacher does not look like the kind of person who would repent.”

“Perhaps it’s because someone lost their life and they’re scared? Some people are just like that. They get carried away on weekdays, but when someone loses their life, they’re scared to death…”

"One day later, he also tried to expel the students who resisted him. How could such an unrepentant guy regret it? Moreover, before he surrendered, such an incident happened in his school."

As he spoke, Dote took out a piece of paper and handed it to Duanmu Ai, who took the letter and glanced at it. "The lustful shameless bastard——Teacher [XXXX], you impose your twisted desires on students who can't resist. We know very well how heinous what you do is, so we decided to steal your twisted desires, Let you confess your crime on your own. I will deal with you tomorrow, so be prepared - the Phantom Thieves of the Heart."

 After reading this letter, Duanmu Ai raised his head in confusion.

"What's this?"

“This was on the school bulletin board one day after the girl jumped off the building, and a few days later, the man surrendered.”

“So, you think everything above is true? Someone stole that man’s sinful desire, so he turned himself in because of his conscience?”

 Duanmu Ai shook the letter paper in his hand, and Dote nodded.

"Yes, we suspect that this is probably the work of the electronic demon."

"Electronic Demon... Electronic Demon can indeed affect the minds of others to a certain extent, but I think you should have tested that man long ago."

Duanmu Ai is not surprised by what electronic demons say. After all, many electronic demons can impose states like 'chaos,' coma, and 'charm' on the human spirit to a certain extent. However, these states can be easily detected once checked. It will be discovered. Departments like Dortmund naturally have similar processes.

"Yes, that's the problem. The test results showed that he was innocent, and he himself said that he didn't know anything about the Phantom Thieves. He just suddenly thought about it. In other words, he was not affected by some kind of spiritual magic. But his personality suddenly changed 180 degrees. There must be something wrong with this, and coupled with the previous letter - we suspect that there must be someone causing trouble."

 “So you came to me.”

 At this moment, Duanmu Ai finally understood.

"Yes, we hope that you will enter that school as a transfer student and investigate as a student. You may be able to find those who distort and change other people's minds. You should understand how dangerous this kind of thing is."

"certainly."

Duanmu Ai nodded slightly, although on the surface, everything the other party did was good. But in fact, this is a very dangerous behavior, because it means that anyone's mind can be changed at will. If this continues, no one will dare to trust anyone else. Once this incident is exposed, the impact on society will be considerable.

“So, we announced the closure of the case on the surface, but privately the police station has begun to secretly investigate the case, so I found you and I hope you can help.”

"No problem, then if I find the Phantom Thieves, should I arrest them or beat them to death on the spot?"

 “Uh…don’t be too violent anyway.”

Hearing Duanmu Ai's question, Dot silently wiped away the cold sweat.

“We still want to ask them how they manipulate other people’s hearts, and then…”

"Then you can control this power to manipulate other people, well, I'd better kill them on the spot."

　　　…………”

Facing Duanmu Ai’s ridicule, Dot had nothing to say and could only stand up.

"No matter what, this matter has attracted attention, and we must find a way to solve this case. Everything about this case is here. As for what to do next... you can decide."

"give it to me."

 After the conversation, Dot left the office, and at this time Lumière also came over and picked up the case file.

 “This is really a strange case.”

“Indeed, Lumière, what do you think? Is there any electronic demon that can do this?”

“As far as I know, there seems to be no electronic demon that can do this.”

 Lumière thought about everything and shook his head.

“Most electronic demons’ mind control abilities are short-term and will fail. Nightmares are experts in this area. We can ask them what they think.”

 “Then it’s decided.”

Hearing this, Duanmu Ai also stood up.

 “Let’s ask the experts for their opinions first.”

 For Duanmu Ai, this is not a difficult thing.

 “Completely distort the human mind in a short period of time?”

 Sitting behind the bar, wearing a leather jacket and a pair of bat wings on her back, the female nightmare looked at Duanmu Ai curiously.

"We don't have such an ability, or rather, no electronic demon has such an ability. Indeed, if it is a long-term mental invasion, we may be able to change other people's perceptions step by step through hints and brainwashing. Of course, this requires It’s a process, and it also depends on how strong the other person’s will is. But turning one person into another person in a short period of time? Impossible, it’s absolutely impossible.”

The female nightmare shook her head, and then raised her chin to the side. Under the dim light, she could see a group of humans lying on the bed. There were men and women among them. At this moment, everyone closed their eyes tightly and fell into In deep sleep. This reminded Duanmu Ai of the original Chaomeng in this world - well, the difference is that these people enjoy it at a higher level than Chaomeng.

"The human spirit is very fragile. In my case, I can indeed stimulate other people's spirits a lot in a short period of time, causing their cognition to collapse. But such an outcome will either turn humans into madmen, or make them crazy. He will become a slave who obeys orders, but to completely distort his personality and become another person, not even the Nightmare Clan can do it."

 “Do you know any electronic demons who can do this?”

"Perhaps you can ask Lady Lilith, but I think the answer will not change. If we had this ability, we would have conquered humans long ago."

 “That is, if you had this ability, you would all be dead long ago.”

Duanmu Ai is also sure that electronic demons do not have such power. There are many people in the Ten Disasters who can do similar things, but that is just like the female nightmare said, simply turning the other party into a submissive one. A slave, rather than a complete change of heart and a completely different person.

 It seems that the only way to determine the situation is to go to that school and investigate.
