Until Saturday, things were tense, but quiet. Meanwhile, one thing happened. Mineta and Ai Messenger's messages did not only deal with the present case. There were personal things among them. Of course, just to a limit, so it wasn't like Ai still single or like that. On Friday, though unwittingly, he ventured inside the "too personal" territory.
"I'm gonna ask you a weird question, but when we broke into Ryosuke's apartment, you weren't very impressed by the sight of there. May I ask what the reason is?"
"This is really a secret that I personally find very embarrassing. I'll tell you tomorrow, but in return you would tell a secret from you."
"Why?"
"You said it. Secret for a secret."
"Okay then."

At ten o'clock on Saturday morning, a bell rang at Ai's apartment. Learning from last week's incident, the door was now bolted, so it only opened a gap. There she was greeted by Mirio, Mineta and a smiling guy with green hair.
"Hi. My name is Midoriya Izuku. Nice to meet you."
After a while the door opened completely.
"Ai Hoshino. Nice to meet you."
After a quick bow, they said they would come back for him at 7 in the evening and then left. He took off his shoes and picked up a slipper.
"Feel yourself at home." Ai said, while she closed and bolted the door.
"Where are Masaya and his wife?"
"In the other half of the apartment. It's a big place, so it wasn't a big deal to move in. Even if this apartment is narrow."
Ai didn't lie very much. One and a half room apartment with a living room, kitchen, bathroom and a wardrobe. Mineta had no time to look around when someone grabbed his waist. Looking sideways, he saw that Aqua is.
"Safe!"
"It's not fair! You always did!" Ruby whined. They must have been playing catch.
"Aqua. Our guest has just arrived. He's not part of your game."
"Sorry, mom."
He noticed something. As if the kids just act. Perhaps the paranoia for events is behind it but could not scratch this feeling of yourself. He sat down in one of the armchairs while Aqua and Ruby continued to play.
"Forgive them for this. They're very lively." Ai apologized with a smile.
"It's okay. I have a little sister who is equally lively and constantly in need of attention."
"That's great. Can you take care of them while I make lunch?"
"Sure."
Ai left the living room. Mineta noticed that she was as sexy in her home outfit, as she was when she performed, in full makeup. That's what they say, it's not the clothes that make a man or woman. Aqua and Ruby then acted really strange. They stopped playing and looked into his eyes and came closer. As if they are not children, they are just pretending. He felt quite uncomfortable in present situation.
"Hello. Don't worry. I love your mom..."
"We know well. We owe gratitude for saving her life." Aqua said as if he really like an adult.
"Yes. You're a great hero to us. And also a great person." Ruby added with a cute smile. Mineta's brain didn't want to receive this information at first glance. He would have shouted almost after Ai, when they was waving to silence.
"Don't say a word. Mom doesn't know that we reincarnated in their kids." Aqua whispered.
"Of course. We learned about this very rare Quirk type. When one person does not want to die or is rapidly death, there is a 10 percent chance that his consciousness can be rebuilt in a newborn. Briefly, Reincarnation." Mineta said silently.
"You really have a very good mind." Ruby said appreciatively.
"It's more like memory and basic education on my part. Do you remember your old lives?"
"Yes. That's why we wanted to talk to you, and I'm grateful that Ai invited you over. My old name is Gorou Amiyama and my profession was gynecologist."
"Mine is Sarina Tendouji. I was a student." Ruby continued the introduction. "I died in illness. I knew Gorou myself because he was my doctor."
"Fortunately, I don't have to introduce myself. I have done it last week." Mineta laughed softly, but his voice became serious again. "I bet you guys didn't introduce yourself without a reason."
"Yes. I was murdered. I was on my shift the day I died, when someone stabbed me in the back. I couldn't identify the culprit because he was wearing a hood and a mask."
"I envy you on a certain level, for I could not wish for a more grateful rebirth myself. However, my sincere condolences are both."
"Thank you." They both laugh in the end.
"why are you telling me this?"
"I had a chance to see the attacker last week, and I think it was the same guy."
"Ryosuke? Then why didn't the police arrest him the day after your murder?"
"I don't know. That was four years ago..."
Aqua had to stop her sentence, because Ai opened the door. They looked into each other's eyes as an instant improvisation. The one who blinked last won (Which was Ruby.).
"You guys are really having fun." she laughed and go back to the kitchen. "Lunch will be ready in a few minutes."
All three sighed. Mineta took out her notebook and wrote down the information so far.
"I'll investigate this matter tomorrow. Thanks for the information."
"You're welcome. In exchange..."
"Don't worry, Gorou...I mean Aqua. Your secret will be under seven seals. Just one more question. were you a fan of Ai?"
"We still are. As much as you." Ruby answered. From that point on, however, the twin was act again.

At lunch, too, there was an absolutely family atmosphere. Mineta found that Ai wasn't really moving up to Gordon Ramsay's standards in culinary terms.
"I don't want to offend you, because it's delicious, but it does feel like you're still learning." he said with a smile when he finished meals.
"Well, yeah. when I got pregnant, I literally had to learn everything. Miyako, Masaya's wife, cooks for me and teaches me."
"If you needed, I'll tell Bakugo. He's an excellent cook and I think he'd love to share his science with you."
"That would be impossible. He's very mean. That's what I learned from the first meet with him."
Mineta laughed and voluntarily took the washing. Until then, Ai have time to lay the kids. Afterwards, she told him to wait in her room when he was done. He did so. There was no huge room and it seemed that her owner didn't really do anything. He went to bed and took out his notebook. He tried to make some planned plans to further the investigation. Aqua and Ruby's request were to keep their previous life secretly that made things difficult. In return, he only gave more research work, coupled with a lot of questions. If Ryosuke really killed Gorou, why didn't they investigate it? And what was the motive? Did he know that the real culprit was Aqua and Ruby's father? Does the last assassination attempt cover a similar motivation? His thinking was interrupted only by Ai when she was completely lying down on him.
"Well. Where did my little detective gone?" she asked vividly.
"Get of me!" he shouted.
"Quiet! I just laid the kids to slepp and if you don't stop, I'll choke you with my tits."
"I have to die in something."
They both laughed at this answer. She get off from Mineta, so their eyes met again. He immediately pulled himself together and closed his notebook.
"Do you record the evidence?"
"Yes. I use one of these on every case. I have to, otherwise I would often miss a detail. However, you told me you wanted to show me something."
"Oh, yeah." Ai smiled and stepped to her closet. "During Sunday's help, something didn't let my mind rest. The media slipped over it, but I haven't known for a while. I want to ask for your help in this."
She took out a file and handed it to Mineta. Looking inside, there were newspaper clippings. An idol girl was killed by her own fan four years ago. And the next day, the fan was found dead in his apartment. He committed suicide after he admitted in his farewell letter that he killed the singer he loved, because he was kicked off weeks ago. He flipped further, where the suspicion of the last week had begun to be strengthened. Another idol was killed, the perpetrator also committed suicide (The only difference was the motivation.). All this happened two years ago. Last year, a complete team was slaughtered by a too enthusiastic fan on the stage and then shot himself.
"Shit! That was I afraid of!"
"What is it?" Ai asked, preparing the worst answer.
"These are not isolated cases. They all happened on the same day and the script didn't change. The cops and the heroes didn't care, as it was smoothed out so that the culprit was found and the evidence didn't point to a third guy."
"Would it have been the same for me?"
"Exactly. The real culprit may have a quirk that is suspected of doing brainwashing or pumping up their anger. They kill the idol or idol team they love. The effect goes out and realize what they have done. They will kill themselves because of guilt or fear of prison."
"But now the chain is broken? Since I'm still alive."
"Yes. And since it was only rumored to be a hero protected you, the real culprit does not know the real identity of the savior. The worst thing for him was being a Pro Hero, like Endeavor, Hawks, Mirko, Edgeshot. Then the hero and the police will secretly look at all the cases. In that case he is more likely to be caught."
"So what are you gonna do?"
"In addition to sleeping little and drinking so much coffee while my blood type becomes that? I look more seriously at this incidents. From here we are talking about serial killer that makes my situation difficult, but I can start on a single thread."
Unfortunately, I can't provide good news either. In vain I tried to talk to Masaya's head, he won't let go of the Osaka concert to be held in two weeks."
"Does this idiot have money in his brain?"
"Unfortunately, yes. When I tried to argue that there could be an attack there, he just waved away. "This little bunch of grapes will solve it by then." Based on your logic we can say the fact that he takes this case too lightly."
"For All Might's sake! Then I have to catch the culprit before that." he sighted and closed the file. "I'll take this, but I'll give it back at the end of the case."
"Go ahead. If I need something, I am available from your assistance."
In the end, Ai just showed the sign of peace and winked. Mineta laughed a bit of this.

While Aqua and Ruby were napping, Mineta and Ai continued their discussion, which was more of a friendly conversation. The main reason for this is that they have been able to make so much progress in this situation. Mineta, on the other hand, came to the point about one thing.
"Before I forget, you didn't answer the question I asked yesterday. Why is it a secret that you smoothly tolerated Ryosuke's apartment, while Nejire openly stated that she would never keep me in search again?"
Then Ai's smile so far was down. Instead, her facial expression became quite grim.
"Of course, if you tell me, you can ask me anything. Secret for secret."
"Fine, after all, you asked me to be honest with you. But please don't tell anyone my secret. Especially not the media."
"You could trust me completely until now. It won't change now either."
She just sat down next to him and then she started.
"I'm sure you know very well what I told the media about my family background."
"Yes. Very idyllic family, who supported me throughout your carrier."
"As you can guess, it's just a lie. For a reason, since idols can't say the bitter truth, otherwise there is an illusion of perfection was destroyed. Actually my father and mother were criminals. I grew up in the poorest neighborhood. No one wanted me to be born, so there was no miracle that I did not receive a true parental love. They was raised, but in a really lousy way. For them, money meant a lot more than having children. When I became three years old, the first change happened."
"What?"
"My parents were arrested when they broke into a wealthy family. Since I had no other living relatives, I ended up in an orphanage. That was a little better, but only to the extent that I had a stable roof over my head."
"I'm really sorry, but that doesn't answer my question."
"You're right. The point is, I grew up in a mess that took me to Ryosuke's apartment. I remember when the guardian representative vomited himself when he entered the apartment and did not know how to live in such circumstances, especially not to catch any illness. Let's say it's an exaggeration because then I was chickenpox."
"At this point, your lie is no wonder. I can say the opposite about family situation. My mother and my father loves me. Plus supports me in everything. I have a three year old little sister who is also adored."
"Then you really have a great life."Ai grinned at the end before Mineta patted her on the shoulder.
"You too. In fact, it's hard to be a single mother. Especially for me I don't have a kid and I'm a teenager male (Ai almost laughed out loud at this statement.). But you have two beautiful children whom you love and care for with all your heart. You have learned from past mistakes. Also, if you need help outside of the case, I am at your service."
"You're such a sweet cutie pie. I wouldn't be able to thank all of what you have done for me and do."
Ai hugged Mineta with a smile. She felt like someone really cared about her. After a while, however, she asked a question.
"What do I mean to you? I mean, how did you become a fan?"
Now it was his turn to stop smiling.
"To this day, I still have the memory of experiencing the most depressed period of my life. I didn't want a job in the police force, even though I had a place secured by my father and mother. I wanted to be more of a hero, get noticed and be loved by girls. The outside world reacted by trampling to the muddy ground. No one believed in me, ambition here or there. But when your first song was posted online and I listened to it, it was feeling as if I had been replaced. It gave me enormous strength and confidence to me. When I saw you at B-Komachi's first concert, I was sure I would love you and your team until death. Your music saw deep into my soul and gave all the will to overcome any obstacle. I know, exaggeration, but for me I understand more than any kind of enthusiastic speech. Because of you, I got in the U.A. Hero Academy, plus pseudonym I became a successful crime writer."
The joy was visible in Ai's eyes. She hugged Mineta again, now tighter.
"Then it was worth starting an idol career. You can feel that I love my fans."
That's when Aqua and Ruby came. They spent so much time talking, so the kids got up. Ai broke out of the embrace and picked them up.
"Then let's go eat some snacks. You have to go back to the dormitory soon, isn't it?"
Mineta got up with a smile.

Seven o'clock in the evening came soon enough. Mirio and Midoriya were already at the door. Ai also opened.
"I hope nothing bad happened while Mineta was here." Midoriya said.
"Nothing. As a matter of fact, send my regards to your class. I am grateful to you for having a classmate like him."
"Well, the female part is no longer on this opinion." They laughed at Mirio's comment. As they went to the dormitory, Mineta decided completely about his next move. Tonight he will not sleep until you come up with a specific plan for the case.
