Only Ashido and Kirishima stayed in the living room of the college. They just discussed the results of the friday afternoon exercise. Mineta just greeted them, then sat down on one of the kitchen chairs and put his stuff down. That's when the last phone conversation recorded by Ryosuke came to his phone. He picked up his earphones and listened. At the other end of the line, a very silky but cold voice explained how Ryosuke could kill his target. At this moment, for some inexplicable reason, he felt hatred that increased every second. He wanted to finish with himself right away, but he had enough self -consciousness to think. Maybe a huge portion of pain may affect it, but it is a better option when Aizawa looks into his eyes with his Quirk. The Erasure erases the manipulating effect. Only one mistakes slipped into the execution, that he could not even open his mouth. Moreover, he took the large knife used for slicing in his left hand. Deep down, the voice told him to slit his wrists. Instead, he stabbed her in the right hand with all his might.

The effect was not lost for this. Kirishima and Ashido, who haven't been watched Mineta so far, now got their heads right now.
"What happened? Are you alright?" Ashido asked, processing the first shock.
"No... find... Aizawa... sensei."
There was no need to say twice, Kirishima immediately ran for him. Ashido tried to calm him down, but he always folded that he could only forgive anyone in his death. Their sensei arrived a minute later and looked Mineta in the eye without any questions, causing the manipulative quirk to vanish into thin air.
"Take it to the medical wing immediately. He's lost a lot of blood now." Aizawa suggested. Ashido picked him up and immediately ran with it to the medical wing. There, Recovery Girl immediately attended to the massive wound on his hand. He got up slowly and exhausted.
"Hi there." he said silently. "I hope no one was disturbed by my little interlude."
"Interlude?!" Ashido asked in astonishment voice. "You stabbed a huge knife on yourself and mumbled something that everyone just wanted to see dead! It was everything, just not an interlude!"
"Then that means that the culprit's Quirk is even up to a great deal of records."
"What?"
Mineta slowly sat up. He didn't even care if someone else in his classmate knew the details of the investigation. Maybe he's already been pushed them into the line of fire, or they're looking at the notebook and file he left behind.
"I knew the real culprit was using a Quirk when the first idol girl was killed by her own lifeless fan. And the footage found on my phone confirms this."
She looked at him only in bewilderment, but after the brief initiation everything became clear to her.
"Wow. You really deduct this whole thing very quickly." Ashido admitted.
"I left the file in the living room, so everybody know this. I'm going back."
"Unfortunately I can't let you." Recovery Girl said, while she's looked up her paperwork. "You'll spend the whole day in the medical wing."
"But the case..."
"Don't worry. If everyone knows, then let us help you." Ashido suggested. That's what he wanted to avoid in the beginning, but time really pushed him.
"Since there is no other solution, I ask you to examine the sound from the record. I'm sure a member is working at Sakura TV or famous personality. Only those, who can beat this Quirk should listen to the recordings. In addition, the origin of this Quirk should also be investigated. Write my notebook of what you have come to. I left it in the living room with the file. See if it can help."
Ashido then did something strange. She patted Mineta on the shoulder and gave him a kiss on the cheek.
"We'll figure it out. By the way, if you're mauling yourself because of your pervert things, there's only one thing I can say on behalf of all the girls. Although we are not cheerful when you try to voyeur us, or make dirty comments but our anger that comes from it evaporates after a while. You are part of our class, so one eye of the imaginary chain."
He smiled and went back to bed. He watched as Ashido leave and shook his head. No one knows what kind of real burden he have on his shoulders, only Ai. He told her his secret. The days before entering the U. A. when every single day was hell incarnate.

Ashido went back to the living room. Bakugo was cleaning the blood off the counter and tile, while Tsuyu, Kirishima, Kyoka, Midoriya, and Momo looked at Mineta's files and his notebook.
"I knew Mineta was smart, but it's an even higher level than I ever imagined." Kyoka said appreciatively.
"Yes. and this is even more evident if we take the time into consideration." Midoriya added.
"I'm just not gonna clean his blood anymore!" Bakugo shouted. "Next time he stab the knife in his own hands, work after himself!"
"He did this under the influence of manipulating Quirk." Kirishima said. Ashido continued.
"The recording of said Quirk is on his phone, and I got it. That's what we need to find out. In turn, it should be heard by someone who has no anger or hatred in their heart."
"I'll do it." Kyoka said. "I'll upload it to my computer and disassemble it as audio tracks. Let's see if it can provide a solution."
"Okay. Until then, we look around the Quirk database. Maybe we can scroll ahead of Mineta's investigation."
"Why do we have to do his job?!" Bakugo asked with nervous tone.
"Because he is in the medical wing and needs rest, which in the present situation can mean for him a waste of time and the failure of his current case. Besides, it's voluntary. If you don't want to, I'll do it myself."
There were no more shouting or opposing voices. They all agreed to the investigation. If for no other reason, then for the complete unraveling of the case.

Kyoka took Mineta's phone into her room and connected it to her computer. There she looked up the recording and put it in the audio editing program. She went through the tracks thoroughly and noticed something. The program detected a frequency so high in the caller's voice that normal human ears cannot hear. It is certain that it directly affects the human brain in the chosen person. This may have caused the sudden and uncontrollable anger and hatred. She recorded the data in Mineta's notebook and immediately ran to the library. There, Tsuyu, Kirishima, Midoriya and Momo checked the database of all known Quirks.
"Guys! I have the results of my analysis. We're looking for an ability to act on the human brain through the ear. The sound which cause the mind of those who hear it is taken over by anger and hatred."
After a quick search, they found the only ability that came to mind. Midoriya read aloud.
"Wrath Amplifier! Emitter classified and main tools are sound, speech. The user can enhance anyone's negative emotions, especially anger and hate, so that it completely takes over common sense. The victim acts in such a way that he clearly remembers everything, long after the execution of the deed."
"The worst thing is that if a recording is made during the use of Quirk, it can work. The only downside is that version is weakened effect." Tsuyu added.
"Then that explains why Mineta stab a knife into his hand." Kirishima sighted and wrote the results in Mineta's notebook.
"According to the post here this Quirk disappeared ten years ago." Momo said.
"The first part is ready. I remove the high frequency emitted by the Quirk from the soundtrack, and that way we can more easily identify the sound of the culprit. By the way, where's Ashido and Bakugo?"
"They started to investigate after the culprit." Tsuyu answered. "Since Mineta found that the culprit is some great media member, they started on this thread."
"Let's help them."
They put the database on the quirks back in place and headed for the living room.

There, Bakugo read newspaper articles and posts from his phone. Ashido did the same, but she had a copy of the recording. Since she did not hate anyone, the extra frequency did not blur her mind.
"We have the quirk what we were looking for." Momo said and read Kirishima's note.
"That's a dam cruel Quirk when you think about it." Bakugo mourned.
"And I find the suspect. Hikaru Kamiki. Just as Mineta foretold." Ashido said.
"Is the famous movie star and one of the leaders of Sakura TV? Who appeared in films like "The Blind Woman Looks Back." or "The Submarine in the middle of the Sahara?" Kirishima asked.
"Not funny, red alarm!" Bakugo spoke loudly, looking up from his phone.
"But I see, you're smiling about that."
"Screw you..."
"Stop this. We have better things to do right now."
"You're right, Tsuyu." Kyoka said, then turn to Ashido. "How sure are you for that?"
"Well, in his statements, he views the idol industry as stupid and useless. He's grateful that he got the acting job offer at Sakura TV four years ago, because he couldn't stand another year in the music industry's asshole. Of course, this is his judgment."
"Not to mention that he dated Ai and is presumed to be Aqua and Ruby's father."
Everyone turned to this sound. Mineta was the one who was pale and exhausted. His right hand was completely healed but could barely move.
"Aren't you supposed to be in the medical wing?"
"I talked to Recovery Girl to let go. In return, I promised that I would not do any strenuousness. Where is my phone?"
"I'll give it back." Kyoka spoke and went to her room. When she returned, he had read the developments.
"It's all coming together. The description of quirk fits perfectly with the events of the last four years. Only motivation and direct evidence are missing. Thanks for the help. From here I will take over."
The team handed over everything they received from Mineta without question. Momo, on the other hand, could not stop the case.
"How are you going to get direct evidence?"
"Interesting question. First of all, let me see what my father has done."
His phone indicated that the results of Ryosuke's blood test had arrived. The Wrath Amplifier quirk was found in his blood. There was nothing surprising in this results. He told the others, but they could not come up with any good idea until dinner. They could be sure that they couldn't get close to Hikaru. Mineta, on the other hand thinking about something else.
"Momo! How do you know DNA research machines?"
"How does that relate to the current case?" she asked back confusedly.
"I want to connect two threads right now." he answered and rubbed his eyes.
"I have never researched such topics. But if you ask me, then..."
"No need for it. I will solve it differently."
Mineta didn't want to tell his father about it, but there was no other way. After dinner, he want to tell Ai how things are going.

An hour later, he went up to the Messenger. Ai must have been waiting for a while, because she had already sent him a message half an hour ago.
"Hello, my little detective. Did you get some development?"
"Hi, my dear idol. Well, thanks for you, my assumption come together."
"Wow. So are we really talking about serial killer that he always kill with someone else?"
"Yes. It is a sound -based, manipulating quirk that reinforces anger and hate to an extent that makes one not think clearly and therefore start killing."
"I don't like swearing but that's fucking creepy."
"Yeah. I have experienced myself that this also works for recording."
"Are you okay? Please don't die because of me. :("
"I'm fine. And what I have in common with the class is that I don't die easily. But right now, we neglected the other case a bit."
"The investigation about the real father of Aqua and Ruby?"
"Yes. Will be any celebration for Starberry Productions?"
"The company will celebrate the 8th anniversary of B-Komachi on Friday next week. Why do you ask?"
"Well, we should collect samples for DNA testing."
"What are you planning?"
"Everyone gets their own glass for the clapping. When they drank the drink, the glasses are taken away for washing. That's where my part comes in. Using cotton swabs, I take a saliva sample from the glass they use. And my father and I will make sure that they are examined. You have to do the same from one of your kids."
"This idea is brilliant. They gave you the samples without they thinking."
"Yes. Do you have a place for this event?"
"Not yet. Our old one was closed last year."
Mineta looked up. There were a few classmates in the living room.
"Guys! Did you know a good place to make a party of at least twenty people? Also, they can cooperate with me?"
Midoriya answered instantly.
"My neighbor is a restaurant owner. It operates a pretty good place with a great selection and decent price. The place name is Totomo Restaurant and Bar. I can't answer your second question."
"Thank you." He said and looked back at his phone.
"Can you convince Masaya to book a giant table at Totomo Restaurant and Bar?"
"After all, I can try it with him. Did you want to take part? ;)"
"Without second thinking."
"I'll talk to him tomorrow. But I have to go. Putting the little ones to bed."
"I'll save myself for tomorrow. Take care, my dear idol."
"You too, my little detective."

The next morning, Mineta woke up, but not the alarm sound. Rather, a newly received SMS message. In his message only that was all that.
"Hi, Mineta. I'm Aqua. I just remembered that before my death. I would have received the real identity of the man who made Ai pregnant. But I couldn't look at the result and later disappeared in the sink. Also, my pediatrician colleague, Marayoshi Izumi, was killed at the same time as me. During my last conversation with him, he would have entrusted me with a document. Unfortunately, I didn't get it, so I have no idea what it is. I remember that much. Don't tell anyone this."
Mineta didn't even think much about this, he just wrote it in his notebook. He knew that Hikaru arranged it this way too, but the reason is completely foggy for now. Did he want to eliminate his paternity or could have been a different reason? But he no longer wanted to collect more theoretical evidence. That is why he will have to attend the ceremony.
