On the way, Mineta felt that someone was watching them. He constantly looked behind his back or on the roofs of high houses, but the paranoia did not want to go away. Finally, they arrived at the Medical Center, where they went to the reception. There they saw that they had to go to the first floor. That's when Ai found out she had to go to the bathroom. Mineta went with her, but only until they were out of sight. There, hiding, they waited for the opportunity for the Big Three to go with Todoroki to the third, where his mother is being treated. As soon as they went up the elevator, they immediately rushed to the stairs.
"That was smooth so far." Ai remarked when they reached the first floor. They were welcomed by a spacious and colorful corridor, but they couldn't notice anything else because one of the sisters looked out of the room.
"Finally! Our volunteer has arrived. You should have started your shift an hour ago." she said.
"What? I mean...I'm sorry I'm late. The train's wheel is punctured." Ai said very fast. Mineta got the occasion.
"We really feel sorry for the delay, but my sister helped to move. Just go and then I'll get home."
"Okay, little brother." She laughed and went into the dressing room. Mineta got on the occasion quickly and as the nurse turned away, he started to rush immediately. He watched the rooms in a row until he reached the filing warehouse. Luckily the door was not closed so he slipped loosely and closed behind him. Inside was greeted by a big pile of cabinets, all in ABC order. He searched the section H and opened it. After a long research he found Hikaru Kamiki's file. He took out and read all. It sounded perfectly normal and was rated Quirkless. He would have almost given up hope when a message on the last page stood barely legible.
"To find out the reality, look for my partner's name." he read loudly. What can this writing refer to? To Marayoshi Izumi or Gorou Amiyama? They were the two victims four years ago. Of course! He remembered Aqua's message. Now he confidently pulled out Gorou's file and opened up. And this was crowned with success, because in the middle there was Hikaru's real file. As he guessed, he has a Quirk named Wrath Amplifier, but what's most disturbing thing is in his personality description. According to the then child psychologist, he struggled with a superiority complex. He also shows incredible aggressiveness when they are offended or mentioned to something that he hate or despise. But it was never treated. in addition, he has beaten someone more than once by influencing someone else with his Quirk. He put the file behind his clothes.
"That's why it was a double murder. Hikaru wants to destroy his real life. I definitely have to tell AI this."
He quickly put everything back and closed the cabinet. Then went out into the corridor.

Outside, he looked into the room where she had to go. She wasn't there, so he was heading for the dressing room. He looked in to spot the trouble and the rightness of paranoia was strengthened. the nurse who called her wanted to stab the panicking Ai in the neck with a scalpel.
"Do not worry! A single cut and go to hell. Idols like you are go to the right place... Ai Hoshino."
"No! Get away from me!" she shouted and tried to escape, but hit the wall. Mineta's brain switched immediately. Because if he had thrown his grape ball, he would just come forward and accidentally stabbed the target to save, so he made a bunch of balls into a shield and jumped between the two.
"GRAPE SHIELD!"he shouted triumphantly, and when the scalpel successfully drilled into one of the balls, he immediately kicked her in the face so that she was immediately stunned.
"The second time you saved my life. I'm really grateful to you." Ai whispered and fell to the ground. Mineta threw the shield and hugged her. They stayed like this for a long time when he was facing Nejire.
"Just escort her home? I knew you were investigating." she said with a smug. "We're not stupid either."
"Okay, I admit you caught us. But look at the good side. With this last puzzle piece we just have to trapped the culprit."
Mineta showed them the papers he got. Ai read it and looked in horror at the end. The smile on Nejire's face is gone.
"There is no fairy tale here. We will arrested Hikaru right now."
"That's not an option. He wash himself smoothly with his relationships. Most importantly, let he fall in a live broadcast in front of everyone's eyes. He can no longer do anything as the people will hate it too."
"I see. Just one more question. What about the nurse who attacked Ai?"
"She's innocent, only under the influence of Quirk. Put on a bench and let she rest. She will wake up with a hard headache."
Nejire did so, and they headed downstairs. There Mirio, Tamaki and Todoroki were waiting.
"Any progress?" Mirio asked. Mineta couldn't even answer when his phone rang. It was an unknown number. He picked up. a distorted voice spoke.
"Welcome, Minoru Mineta. You don't have to know who I am, but I tell you that you have something I need. I offer you a business that is better to get in. You give me the newly obtained document, in return guarantee the safety of Ai Hoshino. If you refuse, it will only cause the death of your friends, loved ones and beloved idol and you will be to blame. I'm waiting your answer... detective."
This made his hand clenched into a fist. Is the bastard even watching them? That's how he ran out of patience.
"You got a lot of skin on your face when you're threatened by a hero. Especially when you're do with the lives of all my loved ones. My answer is clear. No, and I'll catch you soon... Hikaru Kamiki."
He pushed out the phone with a similar irritated impulse, and then turned to the company.
"It's time to catch this punk. Can I count on everyone's help?"
The answer to that was yes. The Big Three escorted Ai home, while Mineta went back to the dormitory with Todoroki. Mirio's quick phone call caused both trips to be made by car. It was time to set the plan.

The most difficult task of the detectives has always been to uncovering the culprit. Especially if the culprit is a real cold -blooded psychopath who, moreover, can cut himself out of responsibility. As a result, Mineta had to make the most detailed plan as possible. The choosen location is the gym in U.A. Academy. since there's a room there that's soundproof, the suspect has a right to believe he can spill anything. Here comes the trap part. Namely, in a live broadcast, with hidden cameras, he record everything he'll no longer have a lawyer to protect this. As an alibi, they submit that B-Komachi is holding a small concert in the U. A., where Ai receives the last evidence in the said room. By Monday the plan was more or less in place, there was just one thing he wanted to clear up. He called her over late in the afternoon and explained the matter to her in the living room. The class was actively involved in the investigation, and Tsuyu, in camouflage, listened Mineta's whole telephone conversation with his father. So they already know the thing.
"Ai! There would be an important thing here. Not only does this matter affect this case, but your career will also be at risk." Mineta said in a serious voice and took Ai's hands.
"I know what you're trying to get at. I have to admit to the world that I have children."
"Yes. no matter how hard I try to get this segment out, the suspect can throw it in. Moreover, it is somewhat relevant to the case."
Ai's starry eyes showed inner conflict, but when she responded, she was absolutely determined.
"I have lied enough to the world. If I have to reveal a secret that means my life, then my career as an idol is completely secondary."
"We will love you same regardless. You could be perfect singer, or even an actress."
"Just don't go to work on some reality TV bullshit." Bakugo grumbled. "Then I'll also deny that I'm a fan of you."
Everybody laugh that. Deep down, Mineta was now completely sure of her own success.
